I just moved from Xcode 4.1 to 4.5 in order to supporting IOS version 6.0. 
I modified launch image as 640x1136 pixels and Base SDK is iOS 6.0.
The problem is when I launch the app it throws SIGABRT on main.m and I added exception breakpoint to get more information but It gave breakpoint 1.1 on the same line of the implementation.
However I have noticed that I got a new warning with Xcode 4.5. Warning and Code are written below. Thanks for help.

Warning: 

```
Semantic Issue: 'CountrySettingsViewController' may not respond to 'initWithTitle'

```

Code:

```
CountrySettingViewController *countrySettingView = [[[CountrySettingViewController alloc] initWithTitle:NSLocalizedString(@"selectCountry",@"Select the country title")]retain];

```
