Question

您好我有一个使用NSurlConnection的项目我只想用NSUrlSession替换它。下面是代码.KIndly帮助改变。

- (IBAction)getResponse:(id)sender
{
    [status setText:@"Retrieving response async"];
    [response setText:@""];

    NSURL *requestUrl = [[NSURL alloc] initWithString:url.text];
    NSURLRequest *request = [NSURLRequest requestWithURL:requestUrl cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:60.0];
    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
    [connection start];
}

- (void)connection:(NSURLConnection *) connection didReceiveResponse:(NSURLResponse *)response
{
    NSLog(@"Response recieved");
}

- (void)connection:(NSURLConnection*) connection didReceiveData:(NSData *)data
{
    NSLog(@"Data recieved");
    NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    [response setText:responseString];
    [status setText:@"Response retrieved async"];
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
}

试试这个

   [[[NSURLSession sharedSession]dataTaskWithRequest:request 
  completionHandler:^(NSData * _Nullable data, NSURLResponse * 
  _Nullable response, NSError * _Nullable connectionError) {
   //Handle your response
   }] resume];

将NSUrlConnection替换为NSUrlSession
