【问题描述】：

这些错误是什么以及如何找出这些错误。在我的应用程序中，我使用 GoogleAnalytics、Fabric、Mix 面板、Core Data，我正在向服务器发送参数并从服务器获取数据。

这是我的代码：

- (IBAction)searchButton:(id)sender 

if (sender == self.searchButton) 

    Reachability *networkReachability = [Reachability reachabilityForInternetConnection];
    NetworkStatus networkStatus = [networkReachability currentReachabilityStatus];

    if (networkStatus == NotReachable) 

        UIAlertController * alert = [UIAlertController alertControllerWithTitle : @"Message"
                                                                        message : @"No Internet!Please Connect and try again."
                                                                 preferredStyle : UIAlertControllerStyleAlert];

        UIAlertAction * ok = [UIAlertAction
                              actionWithTitle:@"OK"
                              style:UIAlertActionStyleDefault
                              handler:^(UIAlertAction * action)
                               ];

        [alert addAction:ok];
        dispatch_async(dispatch_get_main_queue(), ^
            [self presentViewController:alert animated:YES completion:nil];

        );

        //        NSLog(@"There IS NO internet connection");
     else 


if ([self.selectOptionButton.currentTitle isEqualToString:@"Select Your Option"]) 

    UIAlertController * alert = [UIAlertController alertControllerWithTitle : @"Message"
                                                                    message : @"Please select option."
