iOS动画

1.UIView属性动画

<1>方法一

- (IBAction)animationAction1:(UIButton *)sender {
    NSLog(@"属性动画");
    // 1.开始动画 第一个参数是名字
    [UIView beginAnimations:@"属性动画" context:nil];
    // 2.设置属性
    // 1)设置动画的持续时间
    [UIView setAnimationDuration:2];
    // 2)动画延迟执行时间
    [UIView setAnimationDelay:1];
    // 3)设置重复次数
    [UIView setAnimationRepeatCount:2];
    // 4)设置自动翻转
    [UIView setAnimationRepeatAutoreverses:YES];
    // 5)设置动画效果控制
    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
    // 设置代理
    [UIView setAnimationDelegate:self];
    // 6)给动画开始的时候添加事件(一定要先设置代理)
    [UIView setAnimationWillStartSelector:@selector(startAnimation)];
    // 7)给动画结束的时候添加事件
    [UIView setAnimationDidStopSelector:@selector(stopAnimation)];
    // 动画效果
    _redView.center = CGPointMake(300, 80);
    // 3.结束动画
    [UIView commitAnimations];
   }

<2>方法二 block

    // 设置持续时间
    sition.duration = 2;
    // 设置过渡方向
    sition.subtype = kCATransitionFromBottom;

    // 1.系统提供的样式 
   sition.type = kCATransitionPush;
    // 2.私有API
    sition.type = @"suckEffect";
    // 添加动画
