UIView 动画    //1.属性动画    //UIView 做动画有两种方式, 动画块方式和block方式, 通常我们使用block方式.    //常用的属性有 背景色, alpha, center, frame, bounds等.    //二. CALayer 核心 绘画层    //UIView 和 CALayer 的关系    //UIView 并不进行渲染和绘画,真正负责渲染的是CALayer    //UIView可以看做是CALayer的代理,负责展示内容以及用户进行交互.    //UIView创建的时候带一个CALayer,UIView与绘制和渲染相关的属性其实是CALayer的属性,比如背景颜色.    //CALayer有很多的属性,UIView可以直接使用只是其中一部分,比如CALayer的圆角等.    //1.创建一个CALayer对象    CALayer *layer = [[CALayer alloc] init];    //2.设置属性    layer.frame = CGRectMake(200, 50, 100, 100);    //圆角    layer.cornerRadius = 50; // 0.5 宽    //边框宽度    layer.borderWidth = 2;    //边框颜色    layer.borderColor = [UIColor redColor].CGColor;    //阴影颜色    layer.shadowColor = [UIColor blueColor].CGColor;    //阴影透明度,默认为 0    layer.shadowOpacity = 0.5;    //阴影偏移量    layer.shadowOffset = CGSizeMake(10, 10);    //背景颜色    layer.backgroundColor = [UIColor yellowColor].CGColor;    //锚点    //x , y  0.0 ~ 1.0 之间数    //默认为 0.5 , 0.5 中心点    layer.anchorPoint = CGPointMake(0, 0);    layer.position = CGPointMake(200 + 50, 50 + 50);    // anchorPoint 默认在视图的中心点，    // layer 的postion 就是 anchorPoint 在父坐标系中的位置为 x: frame.x + 0.5 * width    // y: frame.y + 0.5 * height    // 我们通常设置 如果想要设置position 和 frame 相等。则只要设置 锚点为左上角，则 postion 和 frame 就相等了，但是如果之前设置了frame 会发现 更改锚点后，实际位置会发生变化，这是因为    // 本来    // position.x  = frame.x +   0.5 * width    //      250            200         50    // position.y = frame.y + 0.5 *height    //      100           50       50    // frame 为 200 50  position 为 250 100    // 设置锚点为0 。0 后，重新绘制了视图 position 和 frame相等    // 因此frame 变为  200  50  ---->  250 100    //3.添加到父 layer上    [self.view.layer addSublayer:layer];    //需求:设置一张圆角图片,QQ个人头像    //更改imageView的layer    //圆角    _imageView.layer.cornerRadius = 50;    //边框    _imageView.layer.borderWidth = 2;    _imageView.layer.borderColor = [UIColor yellowColor].CGColor;    //边界马赛克, 边界遮罩    _imageView.layer.masksToBounds = YES; //显示到边界    // Do any additional setup after loading the view, typically from a nib.}#pragma mark-------- 1.UIView属性动画------------- (IBAction)propertyAnimation:(id)sender {    //iOS3.0之前UIView的动画方法都是类方法,需要我们把动画写在一个动画块里面.    /*     [UIView beginAnimation:]     //设置动画属性     [UIView commitAnimations]    */    //1.开始动画    [UIView beginAnimations:@"动画名称" context:@"传递给代理的参数"];    //2.设置动画    //动画持续时间,重复几次,是否反转等等.
