NSURLRequest *req = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:@"https://google.com"]];
NSURLConnection * connect = [[NSURLConnection alloc] initWithRequest:req delegate:self];
[connect start];
这是同步还是异步? NSURLConnection默认是1?nsurlconnection默认是什么?同步还是异步?
我如何在主线程上触发nsurlconnection? 而我该如何做到背景? – MainakChoudhury 2015-04-09 08:26:14
