检索HTTPResponse / HTTPRequest状态代码iPhone SDK？ [英] Retrieve HTTPResponse/HTTPRequest status codes iPhone SDK?

问题描述

我需要检查并评估我的iPhone应用中的HTTP状态代码。我有一个NSURLRequest对象和一个成功（我认为）连接到网站的NSURLConnection：

I need to check and evaluate the HTTP Status Codes in my iPhone app. I've got an NSURLRequest object and an NSURLConnection that sucessfully (I think) connect to the site:

// create the request
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com/"]
                        cachePolicy:NSURLRequestUseProtocolCachePolicy
                    timeoutInterval:60.0];
// create the connection with the request
// and start loading the data
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection) {
    // Create the NSMutableData that will hold
    // the received data
    // receivedData is declared as a method instance elsewhere
    receivedData=[[NSMutableData data] retain];
} else {
    // inform the user that the download could not be made
}

我在这里得到了这个代码： http://developer.apple.com/iphone/library/documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html

I got this code here: http://developer.apple.com/iphone/library/documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html

但它没有（据我所知）说出有关访问HTTP状态代码的任何信息。

But it doesn't (as far as I can see) say anything about accessing HTTP Status codes.

任何人都知道如何建立与网站的连接，然后检查该连接的HTTP状态代码？

Anyone have any idea how to make a connection to a site and then check the HTTP Status Codes of that connection?

提前致谢！

推荐答案

我就是这样做的：

    #pragma mark -
    #pragma mark NSURLConnection Delegate Methods
    - (void)connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse*)response {
         NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;
         int responseStatusCode = [httpResponse statusCode];
    }

但我使用的是异步NSURLConnection，所以这可能对您没有帮助。但我希望它能做到！

But I'm using an asynchronous NSURLConnection, so this may not help you. But I hope it does anyway!
