標籤：

開始抖動

-(void)BeginWobble{    srand([[NSDate date] timeIntervalSince1970]);    float rand=(float)random();    CFTimeInterval t=rand*0.0000000001;    [UIView animateWithDuration:0.1 delay:t options:0  animations:^     {         要抖動的視圖.transform=CGAffineTransformMakeRotation(-0.05);     } completion:^(BOOL finished)     {         [UIView animateWithDuration:0.1 delay:0 options:UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse|UIViewAnimationOptionAllowUserInteraction  animations:^          {              要抖動的視圖.transform=CGAffineTransformMakeRotation(0.05);          } completion:^(BOOL finished) {}];     }];}

停止抖動

-(void)EndWobble{    [UIView animateWithDuration:0.1 delay:0 options:UIViewAnimationOptionAllowUserInteraction|UIViewAnimationOptionBeginFromCurrentState animations:^     {         要抖動的視圖.transform=CGAffineTransformIdentity;     } completion:^(BOOL finished) {}];}
