当我尝试在设备上运行应用程序时出现此错误.当我在模拟器上运行它并且post请求正常工作时,我没有收到此错误.这是我的代码片段：
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:300.f]; [request setHTTPMethod:@"POST"]; NSData* data = [paramString dataUsingEncoding:NSUTF8StringEncoding]; [request setHTTPBody:data]; [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; [connection start];
任何帮助表示赞赏.谢谢
