it isn’t quite like using any 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, pen tip, or anything else; only skin contact
works. That’s too bad for people who wear gloves on the job.
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, 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 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 placing two fingers (usually thumb
and forefinger) on the glass and spreading 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.
The english language has failed apple here. Moving your thumb and forefinger closer together has a perfect verb: pinching. But there’s no word to describe moving them the opposite direction. apple uses the oxymoronic expression pinch out to describe that move (along with the redundant-sounding pinch in). in this book, the opposite of “pinching” is “spreading.”
Double-Tap
Double-tapping is actually pretty rare on the iPhone. It’s not like the Mac or
Windows, where double-clicking 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.
