我不能在我的设备上晃动/移动

Question

这是我的代码。

-(void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event 
{ 
    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(shake) name:@"shake" object:nil]; 
    if(event.type == UIEventTypeMotion && event.subtype == UIEventSubtypeMotionShake) 
    { 

     // SOMETHING HERE 
    } 
      NSLog(@"motion Began"); 
    } 
    else 
    { 
     NSLog(@"Shake Is Over"); 
    } 
} 

我想动摇我device.I /运动使用的代码，但它不工作..

Answer 1

写下下面的代码...然后检查

-(BOOL) canBecomeFirstResponder { 

return YES; 

} 

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

} 

-(void)viewDidAppear:(BOOL)animated { 

[self becomeFirstResponder]; 

} 

-(void)viewDidDisappear:(BOOL)animated { 

[self resignFirstResponder]; 

} 

让我知道它工作与否！

快乐编码！
