当我使用Three20的TTThumbViewController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。我已经成功在缩略图视图中显示图像。现在我想从服务器添加更多图像，因此我需要在视图底部添加“加载更多”按钮，或者当页面滚动到底部时，它会自动加载更多图像。 非常感谢！

试试这个在您的光源类

- (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]; 

}

希望这有助于！
