CAAnimation
需要添加库，和包含头文件

caanimation有多个子类

CABasicAnimation

CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"opacity"];
//@""里的字符串有多种，可以自己找相关资料，一定要填对，动画才会执行 opacity设置透明度 bounds.size设置大小
[animation setFromValue:[NSNumber numberWithFloat:1.0]]; //设置透明度从几开始
[animation setToValue:[NSNumber numberWithFloat:0.3]];//设置透明度到几结束
[animation setDuration:0.1]; //设置动画时间
[animation setRepeatCount:100000];//设置重复时间
[animation setRepeatDuration:4]; //会限制重复次数
[animation setAutoreverses:NO];//设置是否从1.0到0.3 再从0.3到1.0 为一次如果设置为NO则 1.0到0.3为一次
[animation setRemovedOnCompletion:YES]; //完成时移出动画默认也是
[view.layer addAnimation:animation forKey:@"abc"];//执行动画

CAKeyframeAnimation

CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"position"];//设置view从初始位置经过一系列点
NSArray *postionAraay = [NSArray arrayWithObjects:[NSValue valueWithCGPoint:CGPointMake(100, 20)], [NSValue valueWithCGPoint:CGPointMake(40, 80)],[NSValue valueWithCGPoint:CGPointMake(30, 60)],[NSValue valueWithCGPoint:CGPointMake(20, 40)],[NSValue valueWithCGPoint:CGPointMake(0, 100)],nil];//设置点

NSArray *times = [NSArray arrayWithObjects:[NSNumber numberWithFloat:0.3],[NSNumber numberWithFloat:0.5],[NSNumber numberWithFloat:0.6],[NSNumber numberWithFloat:0.1],[NSNumber numberWithFloat:1.0], nil]; //设置移动过程的时间

[animation setKeyTimes:times];
[animation setValues:postionAraay];
[animation setDuration:5]; //设置动画时间
[bigImage.layer addAnimation:animation forKey:@"dd"]; //执行动画

CATransition

CATransition *animation = [CATransition animation];
animation.duration = 0.5f;
animation.timingFunction = UIViewAnimationCurveEaseInOut;
animation.fillMode = kCAFillModeForwards;
    /*
     kCATransitionFade;
     kCATransitionMoveIn;
     kCATransitionPush;
     kCATransitionReveal;
     */
    /*
     kCATransitionFromRight;
     kCATransitionFromLeft;
     kCATransitionFromTop;
     kCATransitionFromBottom;
     */
animation.type = kCATransitionPush;
animation.subtype = kCATransitionFromBottom;
[view.layer addAnimation:animation forKey:animation];
type也可以直接用字符串
/*
     cube
     suckEffect 卷走
     oglFlip    翻转
     rippleEffect 水波
     pageCurl   翻页
     pageUnCurl
     cameraIrisHollowOpen
     cameraIrisHollowClose
*/
