NSURLConnection sendSynchronousRequest没有阻塞

Question

我在NSOperation中调用了NSURLConnection - sendSynchronousRequest，但该方法立即返回。我希望它能阻止操作，直到收到所有数据。这是我的误解吗？

Answer 1

将NSURLConnection对象的委托设置为self

NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

然后实现connectionDidFinishLoading方法

-(void)connectionDidFinishLoading:(NSURLConnection *)connection{
//your code
}
