Searching for a destination

When you want to locate a destination using Maps, the most straightforward method is to search for it:

1. Tap inside the Search box at the top of the screen.
2. Type the name, address, or a keyword or phrase that describes your destination.
3. In the on-screen keyboard, tap Search. Maps locates the destination, moves the map to that area, and drops a pin on the destination, as shown in Figure 11.2.

Now that you have your destination pinpointed (literally), you can read the map to find your way by looking for street names, local landmarks, nearby major intersections, and so on. (You also can use the Maps app to get specific directions; I show you how that works later in this chapter.) The map is also rotatable so, for example, if you’re physically facing east, you can rotate the map so that it also faces east and you can more easily get your bearings. To rotate the map, place two fingers on the screen and rotate either clockwise or counterclockwise.

Getting info about a destination

Knowing where a destination is located is a good thing, but you might also want to find out more about that destination. Maps has you covered there, as well, because it not only provides you with general info such as a phone number, street address, and website address, but it also ties into Yelp, a service that offers user-generated content — particularly ratings, reviews, and photos — of millions of locations around the world. Tap the destination banner and, as you can see in Figure 11.3, Maps offers tons of data about the destination, including basic info, reviews, and photos.

Displaying your current location

When you arrive at an unfamiliar shopping mall and you need to get your bearings, your first instinct might be to seek out the nearest mall map and look for the inevitable You are here marker. This gives you a sense of your current location with respect to the rest of the mall, so locating Pottery Barn shouldn’t be all that hard.

When you arrive at an unfamiliar part of town or a new city, have you ever wished you had something that could provide you with that same You are here reference point? If so, you’re in luck because you have exactly that waiting for you right in your iPhone. Tap the Tracking icon in the lower left corner of the screen, as pointed out in Figure 11.4. (If this is the first time you’ve used the Tracking icon, Maps asks for permission to use your current location, so be sure to tap OK.)

That’s it! Your iPhone examines GPS coordinates, Wi-Fi hotspots, and nearby cellular towers to plot your current position. When it completes the necessary processing and triangulating, your iPhone displays a map of your current city, zooms in on your current area, and then adds a blue dot to the map to pinpoint your current location, as shown in Figure 11.4. Amazingly, if you happen to be in a car, taxi, or other moving vehicle, the blue dot moves in real time.

Seeing what’s near you

Knowing where you are is a good thing, but it’s even better to know what’s nearby. For example, suppose you’re in a new city and you’re dying for a cup of coffee. You could tap Search in the menu bar, tap the Search box, type something like coffee (or perhaps café or espresso, depending on what you’re looking for), and then tap Search. That works, but you might notice something interesting: When you tap inside the Search box, Maps displays icons for a bunch of categories, including Food, Drinks, Shopping, and Fun, as shown in Figure 11.5. Tap a category icon to see its subcategories, as shown in Figure 11.6. Tap one of these icons (such as Coffee Shops) and Maps drops a bunch of pins that correspond to nearby locations that match the subcategory you tapped. Tap a pin to see the name, and tap the banner to see the location’s phone number, address, and other info.

Displaying a map of a contact’s location

In the old days (that is, a few years ago), if you had a contact located in an unfamiliar part of town or even in another city altogether, visiting that person required a phone call or email asking for directions. You’d then write down the instructions, get written directions via email, or perhaps even get a crudely drawn map faxed to you. Those days, fortunately, are long gone thanks to myriad online resources that can show you where a particular address is located and even give you driving directions to get there from here (wherever here may be).

Even better, your iPhone takes it one step further and integrates with Maps to generate a map of a contact’s location based on the person’s contact address. So as long as you’ve tapped in (or synced) a contact’s physical address, you can see where he or she is located on the map.

To display a map of a contact’s location, follow these steps:

1. In the Home screen, tap the Contacts icon. The Contacts app appears.
2. Tap the contact you want to map. Your iPhone displays the contact’s data.
3. Tap the address you want to view. Your iPhone switches to the Maps app and drops a pushpin on the contact’s location.

Mapping an address from an email

Addresses show up in all kinds of email messages these days. Most commonly, folks include their work or home addresses in their email signatures at the bottom of each message. Similarly, if the email is an invitation, your correspondent almost certainly includes the address for the event somewhere in the message.

If you need to know where an address is located, you might think that you need to copy the address from the message and then paste it into the Maps app. Sure, that works, but it’s way too much effort! Instead, just do this:

1. In the Mail app, display the message that includes the address.
2. Tap and hold on the address in the message to display a list of actions. If the address is displayed as a link (that is, underlined in a blue font), it means Mail recognizes it as an address, so you can just tap the address and skip the next step.
3. Tap Open in Maps. The Maps app opens and drops a pushpin on the address.

Specifying a location when you don’t know the exact address

Sometimes you have only a vague notion of where you want to go. In a new city, for example, you might decide to head downtown and then see if there are any good coffee shops or restaurants. That’s fine, but how do you get downtown from your hotel in the suburbs? Your iPhone can give you directions, but it needs to know the endpoint of your journey, and that’s precisely the information you don’t have. Sounds like a conundrum, for sure, but there’s a way to work around it. You can drop a pin on the map in the approximate area where you want to go. The Maps app can then give you directions to the dropped pin.

Here are the steps to follow to drop a pin on a map:

1. In the Maps app, display a map of the city you want to work with:
   • If you’re in the city now, tap the Tracking icon in the lower left corner of the screen.
   • If you’re not in the city, tap Search, tap the Search box, type the name of the city (and perhaps also the name of the state or province), and then tap the Search button.
2. Use finger flicks to pan the map to the approximate location you want to use as your destination.
3. Tap Info (i) in the lower right corner of the screen. The Maps app displays a list of map options.
4. Tap Drop a Pin. The Maps app drops a purple pin in the middle of the current map.
5. Tap and hold the purple pin until it’s released, then drag the pin to the location you want. The Maps app creates a temporary bookmark called Dropped Pin that you can use when you ask the iPhone for directions (as described next).

Getting directions to a location

One possible navigation scenario with the Maps app is to specify a destination (using a contact, an address search, or a dropped pin) and then tap the Tracking icon. This gives you a map that shows both your destination and your current location. You can then eyeball the streets to see how to get from here to there. Depending on how far away the destination is, you may need to zoom out — by pinching the screen or by tapping the screen with two fingers — to see both locations on the map.

“Eyeball the streets”? Ha, how primitive! The Maps app can bring you into the twenty-first century not only by showing you a route to the destination but also by providing you with the distance and time it should take and by giving you street-by-street, turn-by-turn instructions, whether you’re driving or walking. It’s one of the sweetest features of your iPhone, and it works like so:

1. Use the Maps app to add a pushpin for your journey’s destination. Use whatever method works best for you: the Contacts list, an address search, a dropped pin, or a bookmark.
2. Tap Directions in the menu bar (pointed out earlier in Figure 11.2). The Maps app displays a route that assumes you want to leave from your current location and that you want to drive. If those assumptions apply, skip to Step 7.
3. Tap inside the location box at the top of the screen. Maps opens the Directions screen, as shown in Figure 11.7.
4. If you want to use a starting point other than your current location, tap the Start box and then type the address of the location you want to use.
5. Tap Route. Maps returns to the route.
6. Tap the button for the type of directions you want: Drive, Walk, or Transit. Maps figures out the best routes and then displays them on the map in the Overview screen, which also shows the trip distance and approximate time.
7. Tap the route you prefer to take.
8. Tap Start. The Maps app displays the first leg of the journey.

Maps features turn-by-turn directions for driving and walking. This means that as you approach each turn, Siri tells you what to do next, such as “In 400 feet, turn right onto Main Street.” The Maps app also follows along the route, so you can see where you’re going and what turn is coming up. You can see your estimated time of arrival, remaining travel time, and distance remaining by tapping the screen.

After tapping the screen, you can also tap Overview to see the entire route. Instead of seeing the directions one step at a time, you might prefer to see them all at once. Tap the screen and then tap the List icon in the middle of the menu bar at the bottom of the screen.

Getting live traffic information

Okay, it’s pretty darn amazing that your iPhone can tell you precisely where you are and precisely how to get somewhere else. However, in most cities it’s the getting somewhere else part that’s the problem. Why? One word: traffic. The Maps app might tell you the trip should take 10 minutes, but that could easily turn into a half-hour or more if you run into a traffic jam.

That’s life in the big city, right? Maybe not. If you’re on a highway in a major city, the Maps app can most likely supply you with — wait for it — real-time traffic conditions! This is really an amazing tool that can help you avoid traffic messes and find alternative routes to your destination. Maps can also show you traffic construction sites, and it gathers real-time information from Maps users to generate even more accurate traffic data. If you’re in the middle of turn-by-turn directions, Maps even recognizes an upcoming traffic delay and offers an alternative route around it!

To see the traffic data, tap the lower right corner of the screen, and then tap Show Traffic. As you can see in Figure 11.8, Maps displays an orange dotted line to indicate traffic slowdowns, a red dashed line to indicate very heavy traffic, and Road Closed icons to indicate route closures.

Viewing transit info

If you’re trying to get around in an unfamiliar city (or an unfamiliar part of town), some of the most common questions you might asks are, “Where’s the nearest subway stop?” and “What streetcar line is this?” The latest version of the Maps app is happy to answer such questions thanks to its new Transit layer that shows information about transit stops and lines. To see this layer, tap the blue More Info icon in the lower right corner, then tap Transit.

Controlling Maps with Siri voice commands

You can use the Siri voice-activated assistant to control Maps with straightforward voice commands. You can display a location, get directions, and even display traffic information. Tap and hold the Home button (or press and hold the Mic button of the iPhone headphones, or the equivalent button on a Bluetooth headset) until Siri appears.

To display a location in Maps via Siri, say “Show location” (or “Map location” or “Find location” or “Where is location?”), where location is an address, name, or a Maps bookmark. Similarly, to get directions from Siri, say “Directions to location,” where location is an address, name, or a Maps bookmark. To see the current traffic conditions, say “Traffic location,” where location can be a specific place or someplace local, such as “around here” or “nearby.” To get your current location, you can say “Where am I?” or “Show my current location.”

Turning off location services

The next couple of sections show you how to turn off location services for individual apps as well as individual system services. That fine-grained control is the best way to handle location services, but there may be times when you prefer a broader approach that turns off location services altogether. For example, if you’re heading to a secret rendezvous (how exciting!) and you’re bringing your iPhone with you, you might feel more comfortable knowing that no app or service on your iPhone is tracking your whereabouts. On a more mundane level, location services use up battery power, so if your iPhone is getting low or if you just want to maximize the battery (for a long bus ride, for example), then turning off location services completely will help.

Follow these steps to turn off all location services on your iPhone:

1. On the Home screen, tap Settings. The Settings app appears.
2. Tap Privacy. The Privacy settings appear.
3. Tap Location Services. The Location Services settings appear.
4. Tap the Location Services switch to the Off position. If you have Find My iPhone activated (see Chapter 2), your iPhone asks you to confirm.
5. Tap Turn Off. Your iPhone shuts off all location services.

Controlling app access to GPS

When you open an app that comes with a GPS component, the app displays a dialog like the one shown in Figure 11.9 to ask your permission to use the GPS hardware in your iPhone to determine your current location. Notice that iOS only allows apps to access your location while you use the app. Once you exit the app, it can no longer access your location. Tap Don’t Allow if you think that your current location is none of the app’s business, or tap Allow if that’s just fine with you.

A slightly different scenario is when an app must use your location to function. A good example is Foursquare, which requires your location to show you nearby business and to let you “check in” to those places. In this case, iOS automatically gives the app access to your location while you’re using the app, but the app might request access to your location even when you’re not using it, as shown in Figure 11.10. Again, tap Don’t Allow if you think the app is overstepping its bounds, or Allow if it’s all good.

Whatever type of permission you choose, after you make your decision, you might change your mind. For example, if you deny your location to an app, that app might lack some crucial functionality. Similarly, if you allow an app to use your location, you might have second thoughts about compromising your privacy.

Whatever the reason, you can control an app’s access to GPS by following these steps:

1. In your Home screen, tap Settings. The Settings app appears.
2. Tap Privacy. The Privacy settings appear.
3. Tap Location Services. The Location Services screen appears.
4. Configure app access to GPS as follows:
   • If you want to deny your current location to all apps, tap the Location Services switch to Off.
   • If you want to deny your current location to a specific app, tap the app and then tap Never.
   • If you want to allow a specific app to access your current location, tap the app and then tap either While Using the App (the app can only access your location when you use it) or Always (the app can access your location even when you’re not using it).

Enabling or disabling system location services

Your iPhone also provides location services to various internal system services that perform tasks, such as calibrating the iPhone compass, setting the time zone, and serving up iAds that change depending on location data. If you don’t want your iPhone providing any of these services, you can turn them off this way:

1. On the Home screen, tap Settings. The Settings app appears.
2. Tap Privacy. The Privacy screen appears.
3. Tap Location Services. The Location Services screen appears.
4. Tap System Services. The Settings app displays the System Services screen.
5. For any system service to which you don’t want to provide access to location data, tap its switch to Off.
