iOS 8: UIAlertView / UIAlertController not showing text or buttons

I have an UIAlertView which is getting shown perfectly in iOS 7 but in iOS 8, it does not show any buttons or labels. Alert is still visible but just a small white box.
The OK and cancel buttons take their events as well but no texts are visible.

I have used this alert to show on click of a button

- (IBAction)sel_btnLogout:(id)sender {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Logout!" message:@"Are you sure you want to logout?" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];
[alert show];

I checked the frame in iOS 8: it is giving (0,0,0,0) but in iOS 7 it is giving a definite value.

I also checked for iterating into the subviews of uialertview. In iOS7, it goes in the loop, as it finds alert's subviews. In iOS8, it says there are no subviews of alertView.

Answer Source

I got the answer to my issue. The issue was that I was using UIFont+Replacement category in my project. This was working fine on iOS 7 but on iOS 8 it was using few deprecated methods. Due to this, I don't know why, but only my alert view was not showing any labels.

Solution: Deleted the category from the project and set font through xib. Once we place the .tff file of any font in our project workspace, we see those font names in the xib under custom fonts. NO NEED TO USE UIFont+Replacement category.
