Question

我有CABasicAnimation .fromValue和.toValue在PNG图像中移动202张图片并逐个显示

我还使用CALayer来保存image.png

它按顺序传递所有图像的问题我希望按照我将放在NSArray

中的帧来显示图像

这是我的代码：

CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"sampleIndex"];
anim.fromValue = [NSNumber numberWithInt:1];
anim.toValue = [NSNumber numberWithInt:203];
anim.duration = 1.75f;
anim.repeatCount = HUGE_VALF;
anim.autoreverses = YES; 
[myImage addAnimation:anim forKey:nil];

并且帧数组是：

frames =   (753, 377, 798, 422)  ,
  (706, 377, 751, 422)  ,
  (659, 377, 704, 422)  ,
  (612, 377, 657, 422)  ,
  (565, 377, 610, 422)  ,
  (518, 377, 563, 422)  ,
  (518, 424, 563, 468)  ,
  (471, 424, 516, 468)  ,
  (424, 424, 469, 468)  ,
  (471, 377, 516, 422)  ,
  (424, 377, 469, 422)  ,
  (377, 377, 422, 422)  ,
  (330, 377, 375, 422)  ,

依旧......

任何想法？

与您的帧阵列类似，您可以将所有需要的图像（帧）添加到UIImageView。这是一个例子：

NSArray *images = [NSArray arrayWithObjects: 
              [UIImage imageNamed:@"frame753.png"],
              [UIImage imageNamed:@"frame377.png"],
              [UIImage imageNamed:@"frame798.png"], 

              nil];
yourImageView.animationImages = images; 
yourImageView.animationDuration = 1.75; 
yourImageView.animationRepeatCount = 0;
[yourImageViewstartAnimating];

希望这有帮助。

带有数组帧的CABasicAnimation
