cocoa – 在委托中区分NSURLConnection对象

概述我有两个请求一个接一个地开始.像这样开始请求 NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.google.com"]];NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadI 我有两个请求一个接一个地开始.像这样开始请求

NSURL *url = [NSURL URLWithString:[Nsstring stringWithFormat:@"http://www.Google.com"]];NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];NSURLConnection * connection = [[NSURLConnection alloc]                                initWithRequest:request                                delegate:self startImmediately:NO];[connection scheduleInRunLoop:[NSRunLoop mainRunLoop]                      forMode:NSDefaultRunLoopMode];[connection start];

和另一个这样开始的请求.

NSURL *url1 = [NSURL URLWithString:[Nsstring stringWithFormat:@"http://www.apple.com"]];NSURLRequest *request1 = [NSURLRequest requestWithURL:url1 cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60];NSURLConnection *connection1 = [[NSURLConnection alloc] initWithRequest:request1 delegate:self];[connection1 release];

如何在委托方法中区分这两者？

-(voID)connectionDIDFinishLoading:(NSURLConnection *)connection{}

不希望为此目的保留任何额外的类变量.

解决方法 这很简单 ：

-(voID)connectionDIDFinishLoading:(NSURLConnection *)connection{     if (connection == connection1)     {         //It's for connection1.     }     else if (connection == connection2)     {         //It's for connection2.     }}

你可以通过这个美丽的SO问题：Managing multiple asynchronous NSURLConnection connections
