当我使用Three 20的Thumb ViewController时，如何在缩略图视图底部添加加载更多按钮？

Question

我使用了Three20并使用TTThumbViewController创建了缩略图照片视图。我已在缩略图视图中成功显示图像。现在我想从服务器添加更多图像，所以我需要在视图底部“加载更多”按钮，或者当页面滚动到底部时，它将自动加载更多图像。 非常感谢你！

在你的Photosource类中试试这个

- (void)load:(TTURLRequestCachePolicy)cachePolicy more:(BOOL)more {

if (more) {
    page++;
}

//http://www.theblacksheeponline.com/partypics.php?page=2

NSString *Page =  [NSString stringWithFormat:@"%lu", (unsigned long)page];

NSString *url = [@"http:/.......pics.php?page=" stringByAppendingString:Page];

NSLog(@"ALPhotoSource url: %@", url);

TTURLRequest* request = [TTURLRequest requestWithURL:url delegate:self];

request.cachePolicy = cachePolicy;

// sets the response
request.response = responseProcessor;

request.httpMethod = @"GET";

// Dispatch the request.
[request send];

}

希望这有帮助！
