本文介绍了一种使用UIImageView实现轮播图效果的方法，通过设置图片数组、动画重复次数及持续时间等属性，使得轮播图的实现更为简便。

以前我们做轮播图的时候一般都用NSTimer和UIScrollowView，现在我发现其实使用UIImageView也是能实现的，还更简单了！

代码如下：

@interface ViewController (){
    NSArray *images;
}
@property (weak, nonatomic) IBOutlet UIImageView *myImageView;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    //如果要做轮播图效果，下面的图片就区网络中取
    images=[NSArray arrayWithObjects:[UIImage imageNamed:@"Tutorial_p1.png"],[UIImage imageNamed:@"Tutorial_p2.png"],[UIImage imageNamed:@"Tutorial_p3.png"],[UIImage imageNamed:@"Tutorial_p4.png"],[UIImage imageNamed:@"Tutorial_p5.png"],[UIImage imageNamed:@"Tutorial_p6.png"],[UIImage imageNamed:@"Tutorial_p7.png"],[UIImage imageNamed:@"Tutorial_p8.png"],[UIImage imageNamed:@"Tutorial_p9.png"], nil];
    self.myImageView.contentMode=UIViewContentModeScaleAspectFill;
    //加载图片数组
    //self.myImageView.animationImages=images;
    self.myImageView.animationImages=images;
    //重复次数如果要实现无穷循环播放可以把值设置成HUGE_VALF

    self.myImageView.animationRepeatCount=5;
    //持续时间
    self.myImageView.animationDuration=10;
    [self.myImageView startAnimating];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
- (IBAction)stopAction:(id)sender {
    [self.myImageView stopAnimating];
}
