iOS装置：用于KTPhotoBrowserDataSource

Question

创建动态URL我用这API创建我的应用程序的在线图片库，但问题是我需要创建一个动态库，从示例代码的代码显示来自Flickr只是一些图片，我需要演出从这里URL图像是代码：

例如：www.mysite.com/gallery

并在此URL有很多照片！

- (id)init { 
    self = [super init]; 
    if (self) { 
     // Create a 2-dimensional array. First element of 
     // the sub-array is the full size image URL and 
     // the second element is the thumbnail URL. 
     images_ = [[NSArray alloc] initWithObjects: 

       [NSArray arrayWithObjects:@"http://farm5.static.flickr.com/4001/4439826859_19ba9a6cfa_o.jpg", @"http://farm5.static.flickr.com/4001/4439826859_4215c01a16_s.jpg", nil], 

       [NSArray arrayWithObjects:@"http://farm4.static.flickr.com/3427/3192205971_0f494a3da2_o.jpg", @"http://http://farm4.static.flickr.com/3427/3192205971_0f494a3da2_o.jpg" , nil]; 
    }

}

#pragma mark KTPhotoBrowserDataSource 

- (NSInteger)numberOfPhotos { 
    NSInteger count = [images_ count]; 
    return count; 
} 

- (void)imageAtIndex:(NSInteger)index photoView:(KTPhotoView *)photoView { 
    NSArray *imageUrls = [images_ objectAtIndex:index]; 
    NSString *url = [imageUrls objectAtIndex:FULL_SIZE_INDEX]; 
    [photoView setImageWithURL:[NSURL URLWithString:url] placeholderImage:[UIImage imageNamed:@"photoDefault.png"]]; 
} 

- (void)thumbImageAtIndex:(NSInteger)index thumbView:(KTThumbView *)thumbView { 
    NSArray *imageUrls = [images_ objectAtIndex:index]; 
    NSString *url = [imageUrls objectAtIndex:THUMBNAIL_INDEX]; 
    [thumbView setImageWithURL:[NSURL URLWithString:url] placeholderImage:[UIImage imageNamed:@"photoDefault.png"]]; 
}

是否Gallery网站返回JSON或XML？如果没有，那么你需要阅读从图库网站返回的HTML并检索图像标签。您可以使用http://github.com/topfunky/hpple/tree/master或http://github.com/zootreeves/Objective-C-HMTL-Parser解析HTML。对于简单的HTML，这种方法应该可行。

如果HTML是复杂的，然后使用YQL to scrape画廊网站，并转换成JSON。
