简单动画

首先创建storyboard

#import "ViewController.h"

@interface ViewController ()

@property (retain,nonatomic) IBOutletUIImageView *showImage;

@end

@implementation ViewController

- (void)viewDidLoad

{

    [superviewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

}

//组合动画

- (IBAction)group:(id)sender {

    

    CAAnimationGroup * group = [CAAnimationGroupanimation];

    group.duration =3.0f;

    group.repeatCount =INFINITY;

    

    //放大缩小(transform.scale里的属性)

    CABasicAnimation * scale = [CABasicAnimation        animationWithKeyPath:@"transform.scale"];

//把图片大小转换成动画播放的是时常,所以得转换成NSNumber,从fromValue到toValue;

    scale.fromValue = [NSNumbernumberWithFloat:1.0];

    scale.toValue = [NSNumbernumberWithFloat:2.0];

    

    //设置透明度(opacity里的属性)

    CABasicAnimation * basic = [CABasicAnimationanimationWithKeyPath:@"opacity"];

    

    //应为透明度是从1到0得,但是动画播放的是时常,所以得转换成NSNumber,从fromValue到toValue;

    basic.fromValue = [NSNumbernumberWithFloat:1];

    basic.toValue = [NSNumbernumberWithFloat:0];

    

    //将两个动画放到group里

   NSArray * arr = [NSArrayarrayWithObjects:scale,basic, nil];

    [self.train.layeraddAnimation:group forKey:@"group"];

  //[self.train.layer removeAnimationForKey:@"group"];  //移除动画

    

}

//透明度

}

//layer动画能还原

}

- (IBAction)frameAction:(id)sender {
