视图抖动

- (void)shakeAnimationForView:(UIView *) view{    // 获取到当前的View        CALayer *viewLayer = view.layer;        // 获取当前View的位置        CGPoint position = viewLayer.position;        // 移动的两个终点位置        CGPoint x = CGPointMake(position.x + 10, position.y);        CGPoint y = CGPointMake(position.x - 10, position.y);        // 设置动画        CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position"];        // 设置运动形式        [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];        // 设置开始位置        [animation setFromValue:[NSValue valueWithCGPoint:x]];        // 设置结束位置        [animation setToValue:[NSValue valueWithCGPoint:y]];        // 设置自动反转        [animation setAutoreverses:YES];        // 设置时间        [animation setDuration:.06];        // 设置次数        [animation setRepeatCount:3];        // 添加上动画        [viewLayer addAnimation:animation forKey:nil];            }

创建要抖动的视图

view1 = [[UIView alloc]initWithFrame:CGRectMake(50, 100, 50, 50)];    view1.backgroundColor = [UIColor blueColor];    view1.layer.cornerRadius = 25;    [self.view addSubview:view1];

调用抖动方法

- (IBAction)beginView:(id)sender {    [self shakeAnimationForView:view1];}
