iPhone: Seven Basic Finger Techniques

The way you operating The iPhone is quite different compare with other machine. You do everything on the touch screen instead of with physical buttons. Here’s what you need to know.

Tap
You’ll do a lot of tapping on the iPhone’s on-screen buttons. They’re usually nice and big, giving your fleshy fingertip a fat target. You can’t use a stylus, fingernail, or pen tip; only skin contact works.

Drag
When you’re zoomed into a map, Web page, email, or photo, you scroll around just by sliding your finger across the glass in any direction—like a flick (see below), but slower and more controlled. It’s a huge improvement over scroll bars, especially when you want to scroll diagonally.

Slide
In some situations, you’ll be asked to confirm an action by sliding your finger across the screen. That’s how you unlock the phone’s buttons after it’s been in your pocket, for example. It’s ingenious, really; you may bump the touch screen when you reach into your pocket for something, but it’s extremely unlikely that your knuckles will randomly slide it in just the right way.

You also have to swipe to confirm that you want to turn off the iPhone, to answer a call on a locked iPhone, or to shut off an alarm. Swiping like this is also a great shortcut for deleting an email or text message.

Flick
A flick is a fast, less controlled slide. You flick vertically to scroll lists on the iPhone. You’ll discover, usually with some expletive like “Whoa!” or “Jeez!,” that scrolling a list in this way is a blast. The faster your flick, the faster the list spins downward or upward. But lists have a real-world sort of momentum; they slow down after a second or two, so you can see where you wound up.

At any point during the scrolling of the list, you can flick again (if you didn’t go far enough) or tap to stop the scrolling (if you see the item you want to choose).

Pinch and Spread
In the Photos, Mail, Web, and Google Maps programs, you can zoom in on a photo, message, Web page, or map by spreading.

That’s when you place two fingers (usually thumb and forefinger) on the glass and spread them. The image magically grows, as though it’s printed on a sheet of rubber.

Once you’ve zoomed in like this, you can then zoom out again by putting two fingers on the glass and pinching them together.

Double-Tap
Double-tapping is actually pretty rare on the iPhone, at least among the programs supplied by Apple. It’s not like the Mac or Windows, where doubleclicking the mouse always means “open.” Because the iPhone’s operating system is far more limited, you open something with one tap.

A double tap, therefore, is reserved for three functions:

• In Safari (the Web browser), Photos, and Google Maps programs, doubletapping zooms in on whatever you tap, magnifying it.
• In the same programs, as well as Mail, double-tapping means, “restore to original size” after you’ve zoomed in.
• When you’re watching a video, double-tapping switches aspect ratios (video screen shape)

Two-Finger Tap
This weird little gesture crops up only in one place: in Google Maps. It means “zoom out.” To perform it, you tap once on the screen—with two fingers.
