8 iPad and iPhone Tips and Tricks As you learn more about iOS 9’s new features throughout this book, you’ll also discover how to best utilize them by executing the necessary taps, swipes, pinches, and other finger gestures. As in previous editions of the iOS, when you turn on the device or wake it up from Sleep mode, virtually all of your interaction with the smartphone or tablet is done though the following finger movements and taps on the device’s highly sensitive multitouch display: ■ Tap —Tapping an icon, button, or link that’s displayed on your device’s screen serves the same purpose as clicking the mouse when you use your main computer. ■ Hold —Instead of a quick tap, in some cases it is necessary to press and hold your finger on an icon or onscreen command option. When a hold action is required, place your finger on the appropriate icon or command option, and hold it there with a slight pressure. There’s never a need to press down hard on the smartphone or tablet’s screen. (Hold works with all iOS mobile devices running iOS 9, and is different from the Peek and Pop gestures that are exclusive to the iPhone 6s and iPhone 6s Plus.) ■ Swipe —A swipe refers to quickly moving your finger along the screen from right to left, left to right, top to bottom, or bottom to top, in order to scroll left, right, up, or down, depending on which app you’re using. ■ Pinch —Using your thumb and index finger, perform a pinch motion on the touchscreen to zoom out when using certain apps. Or “unpinch” (by moving your fingers apart quickly) to zoom in on what you’re viewing on screen when using many apps. TIP Another way to zoom in or out when looking at the device’s screen is to double-tap the area of the screen on which you want to zoom in. This works when you’re surfing the Web in Safari or looking at photos using the Photos app, as well as in most other apps that support the zoom in/out feature. To zoom out again, double-tap the screen a second time. ■ Pull-down —Using your finger, swipe it from the very top of the iPhone or iPad’s screen quickly in a downward direction. This causes the Notification Center window to appear. You can hold the device in portrait or landscape mode for this to work. As you’ll discover in Chapter 1, “Tips and Tricks for Customizing Settings,” the functionality of Notification Center and the information you can access from it has been enhanced in iOS 9 and is more customizable than before.
