iPhone的18個(gè)秘密功能！老公老公你別跑？

Group texting is great... until it’s not. To rid yourself of the the ongoing deluge of messages, you can see yourself out by tapping "Details" and scrolling down to where it says "Leave This Conversation.” You’re welcome.

If your short fingers make it difficult to comfortably access the upper rows of apps on the home screen, here a handy tip: double touch (read: do not press) the Home button. It’ll bump the top rows down about halfway.

You can set any video or audio messages that you text someone to disappear two minutes after they're watched or listened to. To set it up, go to Settings > Messages and scroll to the bottom.

Whether you’re in a meeting, out to dinner, or simply ain’t got time for that, you can decline the call and shoot the caller a text by hitting the "Message" button above the "Slide to Answer" notification. Choose from a drop-down of default options including "Sorry, I can’t talk right now," "I’m on my way," and "I’ll call you later?" You can also add custom message options under Settings > Phone.

If you’re too lazy to open the calculator app, you can get answers to any math equation (or get a quick unit or currency conversion) by typing it in plain English in the Spotlight search field (at the top of the screen when you swipe right from the home screen).

If you use the calculator app with any regularity you’ve probably noticed there's no backspace to fix a number you may have typed by mistake. But rather than start over when you mess up, you can swipe left or right in the display to delete your last-typed entry.

You don’t need a full toolbox to hang your pictures -- your iPhone comes with its own built-in level. To access it open the Compass app and swipe left.

When you want to shoot a panoramic shot but would prefer to capture the scene from left to right, rather than the default right to left, just tap the arrow that tracks your stability and it’ll switch sides.

If you think you might die without your iPhone, well, you might be on to something. See, you can set things up so that certain critical medical info can be accessed from the emergency section of your lock screen -- should anyone, EMT or otherwise, find you unresponsive with your phone nearby. To do it, go to the Health app and fill out your Medical ID.

Occasionally, certain Apple apps can be the root cause of all your phone’s wonkiness. If you notice one is being particularly janky, try clearing its cache. In the Podcasts, Music, Game Center, Phone, and App Store apps, tap any single tab at the bottom of its launch screen 10 times in a row.

When you don’t want to interrupt whatever action you're shooting, but also want to capture a killer still, just tap the small white shutter button beside the one you pressed to record and the camera will shoot and save a photo without skipping a beat.

Did you just accidentally ax a tab you were reading? No problem, you can access any you’ve recently closed by holding down the "+" at the bottom of the “New Window” view in Safari.

To find any and all mentions of a specific word or name in Safari, go up to the URL field and type it in. At the bottom of the drop-down of suggested Google searches or recently visited pages that shows up, click “On this page,” and it will highlight any matches in yellow.

If you’ve gone down the rabbit hole on a Wikipedia page (or any article in Safari) and don’t feel like scrolling all the way back to the top, a simple tap of the clock at the top jumps back up. The same trick also applies to text messages.?

Want to check something in your inbox or in another email without leaving whatever email you’re currently responding to? Tap and slide the email subject downwards until it locks to the bottom of the screen, freeing you up to go back and read other messages. When you’re ready to resume what you were working on, tap the subject once and the message will pop back open.
