方法的多个副本。因此，如果您想获取某些URL的内容，则可以使用以下代码这种方法的问题是它将阻塞您在其上调用的任何线程。因此，您可以在线程中调用它，也可以使用其他方法之一。 第二种方法是使用NSURLConnection。这使用委托以事件驱动的方式处理流程。这里有一个很好的方法总结。但是您还需要在委托方法中区分请求。例如-(void) connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *) response { if(connection == connection1) { //Do something with connection 1 } else if(connection == connection2) { //Do something with connection 2 } }- (IBAction)grabURLInBackground:(id)sender { NSURL *url1 = [NSURL URLWithString:@\"http://example.com/path/1\"]; ASIHTTPRequest *request1 = [ASIHTTPRequest requestWithURL:url1]; request1.delegate = self; request1.didFinishSelector = @selector(request1DidFinish); [request1 startAsynchronous]; NSURL *url2 = [NSURL URLWithString:@\"http://example.com/path/2\"]; ASIHTTPRequest *request2 = [ASIHTTPRequest requestWithURL:url2]; request2.delegate = self; request2.didFinishSelector = @selector(request2DidFinish); [reques2 startAsynchronous]; } - (void)request1DidFinish:(ASIHTTPRequest *)request { NSString *responseString = [request responseString]; } - (void)request2DidFinish:(ASIHTTPRequest *)request { NSString *responseString = [request responseString]; }- (IBAction)grabURLInBackground:(id)sender { NSURL *url = [NSURL URLWithString:@\"http://example.com/path/1\"]; __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request setCompletionBlock:^{ NSString *responseString = [request responseString]; }]; [request startAsynchronous]; NSURL *url2 = [NSURL URLWithString:@\"http://example.com/path/2\"]; __block ASIHTTPRequest *request2 = [ASIHTTPRequest requestWithURL:url]; [request2 setCompletionBlock:^{ NSString *responseString = [request2 responseString]; }]; [request2 startAsynchronous]; }
