IOS shake function implementation

When we use it, do we feel that the shake function is dazzling? Is it difficult to implement it?

In fact, otherwise, these are all encapsulated by Apple, which provides a very simple portal for me.

These methods are available in uiresponder:

-(Void) motionbegan :( uieventsubtype) motion withevent :( uievent *) event {nslog (@ "began");}-(void) motioncancelled :( uieventsubtype) motion withevent :( uievent *) event {nslog (@ "cancel");}-(void) motionended :( uieventsubtype) motion withevent :( uievent *) event {nslog (@ "end ");}

These methods can be used directly in the subclass of uiviewcontroller, because uiviewcontroller also inherits from uiresponder.

In implementation, the viewcontroller class must support the shake function.

Code:

[[Uiapplication sharedapplication] setapplicationsupportsshaketoedit: Yes]; [self becomefirstresponder];

-(Bool) canbecomefirstresponder {

Return yes;

}

OK. These two codes support this function.
