Back button not responding ?

Question

I am newbie in iOS development and currently stuck on creating back button. I already placed popViewControllerAnimated method on tapping button, also I test it on debugging mode and back button method is calling but popViewControllerAnimated is not working.

Here is the code.

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIButton *backButton = [[UIButton alloc] initWithFrame:CGRectMake((self.view.frame.size.height-100), 30, 80, 20)];
    [backButton setTitle:@"Back" forState:UIControlStateNormal];
    [backButton addTarget:self action:@selector(BackButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:backButton];

    //some piece of code...

}//end of viewDidLoad method


-(void)BackButtonClicked: (id)sender{  
    [self.navigationController popViewControllerAnimated:YES];
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"testing" message:@"some message" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:@"NO", nil];
    [alert show];

}

On tapping back button this alert is showing but screen is not going back.

Any help regarding this issue will be highly appreciable.

I called this viewController by writing this code in my previous viewController

PlaceTranslatedDetailsViewController *secondViewController =
[self.storyboard instantiateViewControllerWithIdentifier:@"placeTranslatedDetail"];
[self presentViewController:secondViewController animated:YES completion:NULL];

However, this viewController and previous viewController were designed programmatically

Answer 1

use this code:

 [self dismissViewControllerAnimated:YES completion:NULL]
