blocks|key|2301888|text|非常容易实现：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2301889|1)让iOS知道哪个视图控制器是响应器链中的第一个：|2301890|override+func+viewDidLoad()+{

Super easy to implement:

1) Let iOS know which view controller is the first in the responder chain:

<pre><code>override func viewDidLoad() {
 super.viewDidLoad()
 self.becomeFirstResponder()
} 
override func canBecomeFirstResponder() -&gt; Bool {
 return true
}
</code></pre>

2) Handle the event in some fashion:

<pre><code>override func motionEnded(motion: UIEventSubtype, withEvent event: UIEvent?) {
 if(event.subtype == UIEventSubtype.MotionShake) {
 print("You shook me, now what")
 }
}
</code></pre>

blocks|key|2301912|text|Speedy99的快速答案是在Objective+C版本中|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2301913|-+(void)viewDidLoad+{

}

-+(BOOL)canBecomeFirstResponder{

Speedy99's swift answer is in the Objective C version

<pre><code>- (void)viewDidLoad {
 [super viewDidLoad];
 [self becomeFirstResponder];
}

- (BOOL)canBecomeFirstResponder{
 return true;
}

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event{
 if(event.subtype == UIEventSubtypeMotionShake){
 NSLog(@"Why are you shaking me?");
 }
}

You no longer need to add becomeFirstResponder() method.

You just need to add motionEnded function to your code.

<pre><code>override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?) 
{
 // code here
}
</code></pre>

Swift 5

Just add following methods to ViewController and execute the code

<pre><code>override func becomeFirstResponder() -&gt; Bool {
 return true
}

override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?){
 if motion == .motionShake {
 print("Shake Gesture Detected")
 //show some alert here
 }
}
</code></pre>

++++++++if+motion+==+.motionShake+{

}|code-block|syntax|javascript|2302003|此外，您还可以覆盖motionBegan(_:with:)和motionCancelled(_:with:)。与覆盖某些触摸事件不同的是，不需要调用super。|2302004|entityMap^0|0|9|0|0|7|0|6|D|K|G|11|6|18|8|1I|B|0|0|9|K|U|O|0^^$0|@$1|2|3|4|5|6|7|T|8|@$9|U|A|V|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|Z|8|@$9|10|A|11|B|J]|$9|12|A|13|B|J]|$9|14|A|15|B|J]|$9|16|A|17|B|J]|$9|18|A|19|B|J]]|D|@]|E|$]]|$1|K|3|L|5|M|7|1A|8|@]|D|@]|E|$N|O]]|$1|P|3|Q|5|6|7|1B|8|@$9|1C|A|1D|B|J]|$9|1E|A|1F|B|J]]|D|@]|E|$]]|$1|R|3|-4|5|6|7|1G|8|@]|D|@]|E|$]]]|S|$]]

Swift 4, 5 
iOS 10+
<code>UIApplication</code>, <code>UIViewController</code>, <code>UIView</code>, and <code>UIWindow</code> are all <code>UIResponder</code> objects by default which means they can all handle motion events, like shake, without any special configuration. Therefore, simply override the appropriate motion method:
<pre><code>class YourViewController: UIViewController {
 override func motionEnded(_ motion: UIEvent.EventSubtype, with event: UIEvent?) {
 if motion == .motionShake {
 print(&quot;device did shake&quot;)
 }
 }
}
</code></pre>
Additionally, you can override <code>motionBegan(_:with:)</code> and <code>motionCancelled(_:with:)</code>. And unlike overriding certain touch events, there is no need to call super.

I'm developing a app with a gesture system, basically if I turn the iPhone to left my app will do a function, if I turn the iPhone to Right, other function, with others gestures.

I don't have idea how to work with that, i'm trying search in google but not work, the result is only touch gesture and not motion gesture.

someone have a tutorial to help me?

我正在开发一个带有手势系统的应用程序，基本上，如果我把iPhone转到左边，我的应用程序会做一个功能，如果我把iPhone转到右边，其他功能，和其他手势。我不知道如何使用它，我尝试在谷歌搜索，但没有工作，结果只是触摸手势，而不是运动手势。有没有人有教程可以帮我？
