如何判断请求何时结束(使用ASIHTTPRequest)?这是我正在使用的代码:
[request setDidFinishSelector:@selector(requestFinished:)];
...
-(void)requestFinished:(ASIHTTPRequest *)request {
NSLog(@"The request is done.");
}
但是,当请求完成时,“请求已完成”永远不会打印到日志中。难道我做错了什么?感谢。

也许你的连接失败了?在这种情况下,您应该测试 - (void)requestFailed:(ASIHTTPRequest *)请求
您是否设置了请求委托?示例代码:
- (IBAction)grabURLInBackground:(id)sender
{
NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[request startAsynchronous];
}
- (void)requestFinished:(ASIHTTPRequest *)request
{
// Use when fetching text data
NSString *responseString = [request responseString];
// Use when fetching binary data
NSData *responseData = [request responseData];
}
- (void)requestFailed:(ASIHTTPRequest *)request
{
NSError *error = [request error];
}

我忘了将代表设置为自己。糟糕!
[request setDelegate:self];
