I wrote this answer to another question, but I think it will help you. Have a look in particular at the methods
我在另一个问题上写了这个答案，但我认为它会对你有所帮助。特别看一下方法
-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
and
和
-(void) connectionDidFinishLoading:(NSURLConnection *)connection
-(void) connectionDidFinishLoading:(NSURLConnection *)connection
-(void) requestPage
{
NSString *urlString = @"http://the.page.you.want.com";
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageAllowed timeoutInterval:20.0f];
responseData = [[NSMutableData alloc] init];
connection = [[NSURLConnection connectionWithRequest:request delegate:self] retain];
delegate = target;
}
-(void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
if ([response isKindOfClass:[NSHTTPURLResponse class]])
{
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*) response;
//If you need the response, you can use it here
}
}
-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[responseData appendData:data];
}
-(void) connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
[responseData release];
[connection release];
}
-(void) connectionDidFinishLoading:(NSURLConnection *)connection
{
if (connection == adCheckConnection)
{
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
//You've got all the data now
//Do something with your response string
[responseString release];
}
[responseData release];
[connection release];
}

NSHTTPURLResponse * httpResponse = (NSHTTPURLResponse *) response;
int errorCode = httpResponse.statusCode;
NSString *fileMIMEType = [[httpResponse MIMEType] lowercaseString];
For more information, check iOS Docs : NSHTTPURLResponse.
有关更多信息，请查看 iOS 文档：NSHTTPURLResponse。
And be patient: not all connections return NSHTTPURLResponse
并耐心等待：并非所有连接都返回 NSHTTPURLResponse

If you expect that the connection is receiving some data you can use.
如果您希望连接正在接收一些您可以使用的数据。
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
you can then simply convert data to NSString.
然后，您可以简单地将数据转换为NSString.

You can create a subclass and override the - (NSString*) descriptionmethod.
您可以创建一个子类并覆盖该- (NSString*) description方法。
