iphone - 已弃用的 NSURLConnection 方法，是否有替代方法？

Question

我正在设置一个 NSURLConnection 来访问远程服务器:

NSURL *url = [[NSURL alloc] initWithString:projectURL];
NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:60];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

使用以下委托(delegate)方法:

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data

- (void)connectionDidFinishLoading:(NSURLConnection *)connection

- (NSCachedURLResponse *)connection:(NSURLConnection *)connection willCacheResponse:(NSCachedURLResponse *)cachedResponse

所有这些方法都说“在 iOS 2.0 到 iOS 4.3 中可用”。我的问题是我应该以另一种方式为当前的 iOS5 做这件事吗？我需要异步传输，需要传递一个 NSURLCredential 来进行 UID/PWD 认证。

编辑:

所以如果我采用协议(protocol) <NSURLConnectionDelegate>在我的 header 中并使用上面的委托(delegate)方法我这样做是正确的吗？

Answer 1

对于 iOS 5，看起来你可以利用新的 NSURLConnectionDelegate protocol (为您链接的文档)。

And here's a related (or maybe even duplicate?) question that explains even better .
