In this course, Garrick Chow provides in-depth instruction on all aspects of the Apple iPhone and iPod touch (OS 5.0): making calls, emailing, browsing the web, managing time, getting around town, taking notes, shooting photos, and listening to music. New features in iOS 5, including iMessage, the streamlined Notification Center, and Apple's new online storage solution, iCloud, are discussed in depth. The course also includes hands-on demonstrations of how to accurately type and efficiently use finger gestures, and includes tips for setting up the iPhone and iPod touch so they behave as expected. An extensive section on troubleshooting helps when the occasional glitches happen.
One of the most significant new features introduced back with the release of iOS 4 was Multitasking. Multitasking allows you to leave multiple applications running and quickly switch between them. This helps you to do things like start playing games exactly where you left off, leave GPS applications running in the background or have music apps keep playing music while you perform other apps on your device. Multitasking is available on the iPhone 3GS, the iPhone 4 and 4S and the 2nd Generation iPod touch and later. Let's take a look at how it works. I have an app called Pandora installed on my iPhone. It's a popular streaming Internet music app.
So here on my iPhone running iOS 5, I can start some playing and once the music is playing, I can start doing other things on my iPhone while the music continues to play in the background. I'll tap my Home button and maybe I want to work on some email or maybe I want to check the weather. As you can hear, Pandora continues to play music the entire time. Now so far, I've been switching between apps by pressing my Home button to return to the Home screen and then tapping the app I want to run, but another way is to use the Multitasking Bar.
You invoke the Multitasking Bar by double-clicking the Home button, which opens the Multitasking Bar at the bottom of the screen. Here you'll find the icons for all the apps you've most recently opened just tap an app to switch back to it. For example, I'll tap Pandora. Now I can see the status or progress of the music that's currently playing, or in this case, I'll pause it, or I can double-click again to go back to mail right where I left off. And what we'll find is that all your most recent apps are going to appear in the Multitasking Bar and you can access them by flicking the bar to the left to browse through them.
Multitasking also comes in handy when a call comes in interrupting whatever important work you're doing at the time. For example, let's say I'm playing a game and then a call comes in. I can answer the call, have my conversation and when I hang up, the last app I was using in this case the game gets shuffled back to the front exactly where I left off. Now, this doesn't mean every single program here is running in the background and eating a processing and battery power. First of all, apps have to be optimized by their creators to support multitasking, but many app creators have already implemented the support.
Also, the apps listed in the Multitasking Bar may still have to boot up from the beginning instead of where you left off if you haven't opened them awhile. You must recently use apps that always pick-up where you left off though. Another use of the Multitasking Bar is for quitting applications. Occasionally, you'll have an app that starts acting funny or not working properly but since current apps are always running, you may have to force it to quit so you can reboot it. To do this, open the Multitasking Bar by double-clicking the Home button and then hold-down your finger on one of the apps until all the icons start to wiggle. Then tap the red Close icon on the app you're having problems with to quit it.
You can then close the Multitasking Bar and try starting up the app again by tapping its icon. The final features of the Multitasking Bar I want to show you, it can be found by double-clicking the Home button to invoke multitasking and then flicking to the right revealing Music Control buttons which can control both your iPod music and certain enabled apps like Pandora when they are running. We'll look more of these controls in the chapter on using the iPod part of your phone but this is also where you can find the Orientation Lock. Most applications are designed to rotate their displays when you rotate the phone. For example, if I open mail, I can work in both portrait and landscape orientation.
But sometimes, you don't want the content of an app to rotate. For example, if you like to read your iPhone in bed while lying on your side, you don't want the screen to rotate into Landscape Mode. So just double-click the Home button to open the Multitasking Bar, click to the right, and make sure the Orientation Lock button has a Lock icon in it. Then close the Multitasking Bar, incidentally, you can see the Orientation Lock icon in the top right corner of your screen. So now when I rotate my phone, the display remains in Portrait Mode and that's how multitasking works on the iPhone and iPod touch.
