This article mainly introduces the problem of IOS detection shaking, which is very detailed and has a certain reference value. Friends who are interested must read it!

IOS3.0 can be used later as follows

-(void) motionBegan: (UIEventSubtype) motion withEvent: (UIEvent *) event {

}

-(void) motionCancelled: (UIEventSubtype) motion withEvent: (UIEvent *) event {

}

-(void) motionEnded: (UIEventSubtype) motion withEvent: (UIEvent *) event {

}

These three methods detect mobile phone shaking events.

I said two things to pay attention to.

1. To achieve rickety view or viewController, you must add

-(BOOL) canBecomeFirstResponder {

Return YES

}

Note that it is not the-(BOOL) becomeFirstResponder; method.

two。 Add [view becomeFirstResponder] to the viewController of this view, or add it to viewController

[self becomeFirstResponder]

Note that the above code must be added to the

-(void) viewDidAppear: (BOOL) animated {

[super viewDidAppear:animated]

[self becomeFirstResponder]

}

Here

(it will be invalid if it is added elsewhere.)

At the beginning, I added it as follows

-(void) viewWillAppear: (BOOL) animated {

[super viewWillAppear:animated]

}

It seems almost the same here, but in fact it is far from receiving the shaking event at all.
