當我使用Three20的TTThumbViewController時，如何在縮略圖視圖底部添加加載更多按鈕？

Question

我使用了Three20並使用TTThumbViewController創建了縮略圖照片視圖。我已經成功在縮略圖視圖中顯示圖像。現在我想從服務器添加更多圖像，因此我需要在視圖底部添加「加載更多」按鈕，或者當頁面滾動到底部時，它會自動加載更多圖像。 非常感謝！

試試這個在您的光源類

- (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]; 

}

希望這有助於！
