IOS常用的简单动画

第一种 隐式动画

这是一种最简单的动画，不用设置定时器，不用考虑线程或者重画

实现代码：

#import <QuartzCore/QuartzCore.h>

-(void)clickButton:(UIButton*)button
{
    [UIView beginAnimations:nil
                    context:nil];
    CGAffineTransform transform=CGAffineTransformMakeTranslation(180, 200);
    [self.imageView.layer setAffineTransform:transform];
    self.imageView.layer.opacity=1;
    [UIView commitAnimations];
}

 第二种、显示动画

 
    CABasicAnimation *opAnim=[CABasicAnimation animationWithKeyPath:@"opacity"];
    opAnim.duration=6.0;
    opAnim.fromValue=[NSNumber numberWithFloat:25];
    opAnim.toValue=[NSNumber numberWithFloat:1.0];
    opAnim.cumulative=YES;
    opAnim.repeatCount=1;
    [self.imageView.layer addAnimation:opAnim forKey:@"animateOpacity"];
    
    CGAffineTransform moveTransform=CGAffineTransformMakeTranslation(200, 200);
    CABasicAnimation *moveAnim=[CABasicAnimation animationWithKeyPath:@"transform"];
    moveAnim.duration=6.0;
    moveAnim.toValue=[NSValue valueWithCATransform3D:CATransform3DMakeAffineTransform(moveTransform)];
    [self.imageView.layer addAnimation:moveAnim forKey:@"animateTransform"];

CAKeyframeAnimation *opAnim=[CAKeyframeAnimation animationWithKeyPath:@"opacity"];
    opAnim.duration=6.0;
    opAnim.values=@[@0.25,@0.75,@1.0];
    opAnim.keyTimes=@[@0.0,@0.5,@1.0];
    [self.imageView.layer addAnimation:opAnim forKey:@"animateOpacity"];
    
    CGAffineTransform moveTransform=CGAffineTransformMakeTranslation(180, 200);
    CABasicAnimation *moveAnim=[CABasicAnimation animationWithKeyPath:@"transform"];
    moveAnim.duration=6.0;
    moveAnim.toValue=[NSValue valueWithCATransform3D:CATransform3DMakeAffineTransform(moveTransform)];
    moveAnim.delegate=self;
    [self.imageView.layer addAnimation:moveAnim forKey:@"animateTransform"];

keyTimes是一个每个帧片段持续的时间比例，取值范围是0.0-1.0之前
