我的博客：iOS使用UIScrollView处理图片的缩放(图片浏览器)<br />

//效果图

//代码示例

- (IBAction)btnClick:(UIButton *)sender {
    LLPhotoBrowser *photoBrowser = [[LLPhotoBrowser alloc] initWithImages:_images currentIndex:1];
    photoBrowser.delegate = self;
    [self presentViewController:photoBrowser animated:YES completion:nil];
}

- (void)photoBrowser:(LLPhotoBrowser *)photoBrowser didSelectImage:(UIImage *)image {
    NSLog(@"选中的图片为:%@",image);
}
