iOS 一个简单的GIF动画

---

创建imageview那一部分就省略了，我用xib直接拖拽的。

先给imageview创建一个触摸手势。这里不要忘记给imageview设置userInteractionEnabled为YES。

//设置动画开始前的图片

appview.Imageview.image=[UIImage imageNamed:@"动态01.png"];

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(setImage)];

//设置imageview为可以响应事件

appview.Imageview.userInteractionEnabled = YES;

[appview.Imageview addGestureRecognizer:singleTap];

singleTap.delegate = self;//设置代理为自身

[singleTap setNumberOfTapsRequired:1];//1次点击

[singleTap setNumberOfTouchesRequired:1];//1个手指操作

接下来是触摸后响应的方法。

-(void)setImage{

NSLog(@"开始执行动画");

//动画结束后要显示的图片

appview.Imageview.image=[UIImage imageNamed:@"动态13.png"];

appview.Imageview.userInteractionEnabled = NO;

NSMutableArray  *arrayM=[NSMutableArray array];

for (int i=0; i<13; i++) {

[arrayM addObject:[UIImage imageNamed:[NSString stringWithFormat:@"动态%02d.png",i+1]]];

}

//设置动画数组

[appview.Imageview setAnimationImages:arrayM];

//设置动画播放次数

[appview.Imageview setAnimationRepeatCount:1];

//设置动画播放时间

[appview.Imageview setAnimationDuration:8*0.1];

//开始动画

[appview.Imageview startAnimating];

//动画结束后响应事件（我这里是显示了一个关闭按钮）

//[self performSelector:@selector(over) withObject:nil afterDelay:0.8];

//清理动画数组

[appview.Imageview performSelector:@selector(setAnimationImages:) withObject:nil afterDelay:appview.Imageview.animationDuration];

}

OK，搞定了。
