UIView动画

UIView动画

一、commitAnimations方式使用UIView动画

1、commitAnimations方式使用UIView动画

[UIView beginAnimations:@"animation" context:nil]; //UIView开始动画，第一个参数是动画的标识，第二个参数附加的应用程序信息用来传递给动画代理消息

2、延时动画时间（秒）

[UIView setAnimationDuration:1]; //动画持续时间（秒）

3、设置动画曲线，控制动画速度

[UIView setAnimationCurve:UIViewAnimationCurveLinear];

4、设置动画方式，并指出动画发生的位置

[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES]; 

5、 设置动画代理

[UIView setAnimationDelegate:self];

6、 动画结束后调用的方法，注意设置次方法之前要先设置代理

[UIView setAnimationDidStopSelector:@selector(stop)];

7、 提交动画

[UIView commitAnimations];

二、交换本视图控制器中2个view位置

1、创建动画

[UIView beginAnimations:@"animation" context:nil];

2、动画持续时间

[UIView setAnimationDuration:1];

3、动画曲线

[UIView setAnimationCurve:UIViewAnimationCurveLinear];

4、交换位置

[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];

[self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1];//交换位置

5、在commitAnimations消息之前，可以设置动画完成后的回调，设置方法是：

[UIView setAnimationDidStopSelector:@selector(animationFinish:)];

三、使用：CATransition

1、创建动画

CATransition *ansition = [CATransitionanimation];

2、动画持续时间

ansition.duration = 2;

3、 动画循环次数

ansition.repeatCount = 2;

4、 设置动画类型

ansition.type = @"cameraIrisHollowOpen";

5、 设置动画方向

ansition.subtype = kCATransitionFromLeft;

6、设置动画代理

ansition.delegate = self;

7、替换

[self.view exchangeSubviewAtIndex:1 withSubviewAtIndex:0];

8、添加动画

[view.layeraddAnimation:ansition forKey:@"12"];

9、animateWithDuration

[UIView animateWithDuration:1 animations:^{

         //要执行的操作

         _view.frame = CGRectMake(20, 140, 200, 100);

        }];

       [UIView animateWithDuration:1 animations:^{

            //要执行的操作

        } completion:^(BOOL finished) {

            动画结束

        }]；

（1）transition.type 的类型可以有
 淡化、推挤、揭开、覆盖
NSString * const kCATransitionFade;
NSString * const kCATransitionMoveIn;
NSString * const kCATransitionPush;

NSString * const kCATransitionReveal;

 

（2）transition.subtype
 也有四种
NSString * const kCATransitionFromRight;
NSString * const kCATransitionFromLeft;
NSString * const kCATransitionFromTop;

NSString * const kCATransitionFromBottom;

（3）私有的类型的动画类型：

animation.type = @”cube”

animation.type = @”suckEffect”

animation.type = @”oglFlip”//没有方向

animation.type = @”rippleEffect”

animation.type = @”pageCurl”

animation.type = @”pageUnCurl”

animation.type = @”cameraIrisHollowOpen”

animation.type = @”cameraIrisHollowClose”

 

四、具体代码

- (void)viewDidLoad {
    [super viewDidLoad];
    UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeCustom];
    btn1.frame = CGRectMake(50, 50, 100, 30);
    //btn1.backgroundColor = [UIColor blackColor];
    [btn1 setTitle:@"动画一" forState:UIControlStateNormal];
    [btn1 setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
    [btn1 addTarget:self action:@selector(btn1) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn1];
   
    UIButton *btn2 = [UIButton buttonWithType:UIButtonTypeCustom];
    btn2.frame = CGRectMake(120, 50, 100, 30);
    [btn2 setTitle:@"动画二" forState:UIControlStateNormal];
    [btn2 setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
    [btn2 addTarget:self action:@selector(btn2) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn2];
   
    UIButton *btn3 = [UIButton buttonWithType:UIButtonTypeCustom];
    btn3.frame = CGRectMake(190, 50, 100, 30);
    [btn3 setTitle:@"动画三" forState:UIControlStateNormal];
    [btn3 setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
    [btn3 addTarget:self action:@selector(btn3) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn3];
   
    UIView *view = [[UIView alloc]initWithFrame:CGRectMake(375/2.0-50, 300, 100, 100)];
    view.tag = 1;
    view.backgroundColor = [UIColor greenColor];
    [self.view addSubview:view];
}

-(void)btn1{
    UIView *view = [self.view viewWithTag:1];
    [UIView beginAnimations:@"1" context:nil];//创建动画
    [UIView setAnimationCurve:UIViewAnimationCurveEaseIn];//动画曲线
    [UIView setAnimationDelay:0];//延时动画
    [UIView setAnimationDuration:2];//动画持续时间
    [UIView setAnimationRepeatCount:2];//动画循环次数
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:view cache:YES];//设置动画效果，以及要执行的view（动画发生位置，此处是view）
    [UIView setAnimationDelegate:self];//设置动画代理
    [UIView setAnimationDidStopSelector:@selector(stop)];//动画结束后调用的方法，注意设置次方法之前要先设置代理
    [UIView commitAnimations];//提交动画
   
}
-(void)btn2{
    UIView *view = [self.view viewWithTag:1];
    CATransition *ansition = [CATransition animation];//创建动画
    ansition.duration = 2;//动画持续时间
    //ansition.repeatCount = 2;//动画循环次数
    ansition.type = @"cameraIrisHollowOpen";//设置动画类型
    ansition.subtype = kCATransitionFromLeft;//设置动画方向
    ansition.delegate = self;//设置动画代理
    [view.layer addAnimation:ansition forKey:@"12"];//添加动画
   
}
-(void)btn3{
    UIView *view = [self.view viewWithTag:1];
    CGPoint center = view.center;
    //放大效果
//    [UIView animateWithDuration:1 animations:^{
//        view.frame = CGRectMake(10, 10, 300, 300);
//        view.center = center;
//       
//    }];
    //放大缩小连续
    [UIView animateWithDuration:1 animations:^{
        view.frame = CGRectMake(10, 10, 300, 300);
        view.center = center;
    } completion:^(BOOL finished) {
        [UIView animateWithDuration:1 animations:^{
            view.frame = CGRectMake(375/2.0, 300, 100, 100);
            view.center = center;
        } completion:^(BOOL finished) {
            [self btn3];//添加动画
        }];
    }];
   
    //实现缩小和放大

    [UIView animateWithDuration:1 delay:1 options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{
        view.frame = CGRectMake(10, 10, 300, 300);
        view.center = center;
    } completion:^(BOOL finished) {
        [UIView animateWithDuration:1 animations:^{
            view.frame = CGRectMake(375/2.0, 300, 100, 100);
            view.center = center;
        }completion:^(BOOL finished) {
            [self btn3];
        }];

    }];

   
}

-(void)stop1{
    NSLog(@"动画停止");
}
-(void)animationDidStart:(CAAnimation *)anim{
    NSLog(@"动画开始");

}
