Objective C https 请求在恢复主线程之前不等待响应

Question

我的 https 请求有问题（我认为是问题所在）。我的问题是我有一个登录页面询问我编写的 php Web 服务，以检查尝试登录的用户是否可以这样做。从 Xcode 启动应用程序时，HTTPS 请求工作正常，但经过苹果验证后，我在 App Store 上发布了该应用程序，但不知何故，当我从 App Store 下载它时，当我按下启动请求的登录按钮时，应用程序冻结...

这是我的请求代码：

NSString *url = [NSString stringWithFormat:@"https://cataloguetest.tabuleo.fr/Appmobile/webServ_firstCo.php?username=%@",username];
__block BOOL endOfBlock = false;
__block NSArray *ret;
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:@"GET"];
[request setURL:[NSURL URLWithString:url]];

[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:
  ^(NSData * _Nullable data,
    NSURLResponse * _Nullable response,
    NSError * _Nullable error) {

      NSString *strData = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
      NSLog(@"Data received: %@", strData);
      NSError *jsonerror;
      NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:0 error:&jsonerror];
      NSString *validity =[jsonDict objectForKey:@"valid"];
      NSLog(@"get validity ok..");
      NSString *userInbase = [jsonDict objectForKey:@"usrIn"];
      NSLog(@"validity: %@",validity);
      NSLog(@"inBase: %@", userInbase);
      ret = @[validity ,userInbase];
      endOfBlock = true;
  }] resume];
while (!endOfBlock) {};

感谢您的帮助。

好的，我设法找到了几乎完美的方法：

NSString *urlCheck = [NSString stringWithFormat:@"YOUR URL"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:@"POST"];
[request setURL:[NSURL URLWithString:urlCheck]];
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:
^(NSData * _Nullable data,
NSURLResponse * _Nullable response,
NSError * _Nullable error) {
  //do things with request's return
}] resume];

while(!postRequestReturned){

[[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate          distantFuture]];

}
NSLog(@"REQUEST resumed main thread");
