IOS中UIImageView方法实现简单动画

animationImages;
highlightedAnimationImages;
animationDuration;
animationRepeatCount;
- startAnimating;
- stopAnimating;
- isAnimating;

self.imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"test.jpg"]];
[self.view addSubview:self.imageView];
self.imageView.frame = CGRectMake(0, 0, 150, 450);
self.imageView.animationImages = 
@[[UIImage imageNamed:@"f-0.jpg"],
[UIImage imageNamed:@"f-1.jpg"],
[UIImage imageNamed:@"f-2.jpg"],
[UIImage imageNamed:@"f-3.jpg"],
[UIImage imageNamed:@"f-4.jpg"],
[UIImage imageNamed:@"f-5.jpg"],
[UIImage imageNamed:@"f-6.jpg"],
[UIImage imageNamed:@"f-7.jpg"],
[UIImage imageNamed:@"f-8.jpg"],

[UIImage imageNamed:@"f-12.jpg"],
[UIImage imageNamed:@"f-13.jpg"],
[UIImage imageNamed:@"f-14.jpg"],
[UIImage imageNamed:@"f-15.jpg"],];
self.imageView.animationDuration = 5.0;
self.imageView.animationRepeatCount = 0;
[self.imageView startAnimating];
