• 이 목표 - C와 IOS에 메신저의 새로운 .. 내가 ASIHTTPRequest을 사용 ..
• 문제입니다 "NSLog (@"표시 자 : % @ ", mArrData)"를 파싱 및 표시하는 동안 동결 상태가 발생했습니다.이 코드를 개선 할 수있는 방법이 있습니까?
• 나는 GCD (그랜드 센트럴 파견)에 대해 들어
• URL 요청에 대해 수행 다만 ASINetworkQueue 같은 다른 스레드에서 그 일을 같은 코드를 개선하기 좋아하지만 .. 유용 얼마나 심지어 알고
해달라고 것

사전에서

고맙습니다 당신이 ASINetworkQueue을 사용하고 단순한 ASIHTTPRequest을 사용하고 startAsynchronous를 사용하지 않는 시도? 예를 들어 : 여러 요청이있는 경우

NSURL *url = [NSURL URLWithString:@"http://mikan-box.x10.bz/testing/json_test.php"]; 
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; 
[request setDelegate:self]; 
[request startAsynchronous]; 

당신은 requestFinished:에서 그들을 구별하는 [request setTag:tag]를 사용할 수 있습니다.
