ASINetworkQueue请求allways失败 - ios

Question

我正面临一点点的麻烦，发现我的代码有什么问题，因为我试图从不同的URL下载多个图片，并且请求无法通过。

你们能帮我一下吗？

这里是我的代码：

     [networkQueue addOperation:request]; 



    } 


    [networkQueue go]; 
} 

- (void)requestFinished:(ASIHTTPRequest *)request 
{ 
    // You could release the queue here if you wanted 
    if ([networkQueue requestsCount] == 0) { 

    // Since this is a retained property, setting it to nil will release it 
     // This is the safest way to handle releasing things - most of the time you only ever need to release in your accessors 
     // And if you an Objective-C 2.0 property for the queue (as in this example)  the accessor is generated automatically for you 
     [self setNetworkQueue:nil]; 
    } 

    //... Handle success 
    NSLog(@"Request finished"); 
}

     [self setNetworkQueue:nil]; 
    } 

    //... Handle failure 
    NSLog(@"Request failed"); 
}

Answer 1

嗯，这是不好的URL格式相关的问题。

我是路过的http：/somesite.com/someimage.png强似http://somesite.com/someimage.png

我失踪了/因为当我使用stringByAppending路径追加BASEURL字符串的文件名部分它消除了一个斜线HTTP：//。

现在解决！
