使用三个UIImageView实现图片的无限循环，可手动拖拽和点击交互

添加到你的项目

手动添加

1. 将ZPLoopScrollView.h和ZPLoopScrollView.m添加到你的项目中。ZPLoopScrollView需要ARC。

使用

- (void)viewDidLoad {
      [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    //    NSString * path = [[NSBundle mainBundle] pathForResource:@"ImageInfo.plist" ofType:nil];
    //    NSDictionary  * dic = [NSDictionary dictionaryWithContentsOfFile:path];
    //    
    //    NSMutableArray * array = [NSMutableArray array];
    //    for (NSString * str  in dic.allKeys) {
    //        UIImage * i = [UIImage imageNamed:str];
    //        [array addObject:i];
    //    }

        [self.view addSubview:self.scrollView];
        //设置展示图片
        //self.scrollView.images = array;
        //设置网络图片
        self.scrollView.imagesURL = @[@"http://img4.duitang.com/uploads/item/201204/11/20120411162656_eJJiZ.jpeg",
                                      @"http://img.ycwb.com/news/attachement/jpg/site2/20110226/90fba60155890ed3082500.jpg",
                                      @"http://imgsrc.baidu.com/forum/pic/item/b03533fa828ba61e78ab1c894134970a314e59cb.jpg",
                                      @"http://pic27.nipic.com/20130227/7224820_020411089000_2.jpg"];
         //设置pageControl在self.scrollView高度的比例,默认为0.8
         self.scrollView.pageControllCenterYScale = 0.5;
}
#pragma mark - delegate
- (void)scrollViewLoopDidEndClicked:(ZPLoopScrollView *)scrollViewLoop index:(NSUInteger)index
{

}
#pragma mark - setter & getter
 - (ZPLoopScrollView *)scrollView
{
    if (!_scrollView) {
    _scrollView = [[ZPLoopScrollView alloc]initWithFrame:self.view.bounds];
    _scrollView.delegate = self;
    }
    return _scrollView;
}
