iPhone App crashes after localization of xib file

Question

I am creating my first iPhone app in which the first screen displays a table view the user selects from. It works before localization using the method below.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

// Override point for customization after application launch.
navigationController = [[UINavigationController alloc] init];

[self.window addSubview:[self.navigationController view]];

if(self.selectCategoryViewController == nil)
{
    SelectCategoryViewController *viewTwo = [[SelectCategoryViewController alloc] initWithNibName:@"SelectCategoryViewController" bundle:[NSBundle mainBundle]];
    self.selectCategoryViewController = viewTwo;
    [viewTwo release];
}
[self.navigationController setNavigationBarHidden:YES];//this will hide the navigation bar
[self.navigationController pushViewController:self.selectCategoryViewController animated:YES];


//self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];

return YES;
}

After I localized it by adding the Japanese localization file and changing the above to this:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

// Override point for customization after application launch.
navigationController = [[UINavigationController alloc] init];

[self.window addSubview:[self.navigationController view]];


if(self.selectCategoryViewController == nil)
{

    NSBundle *myLocalizedBundle=[NSBundle bundleWithPath:[NSString stringWithFormat:[[NSBundle mainBundle]bundlePath],"en.lproj"]];
    NSLog(@"the localized bundle is %@",myLocalizedBundle);
    SelectCategoryViewController *viewTwo=[[SelectCategoryViewController alloc] initWithNibName:@"SelectCategoryViewController" bundle:myLocalizedBundle];

    self.selectCategoryViewController = viewTwo;
    [viewTwo release];


}
[self.navigationController setNavigationBarHidden:YES];//this will hide the navigation bar
[self.navigationController pushViewController:self.selectCategoryViewController animated:YES];

[self.window makeKeyAndVisible];

return YES;
}

it crashes with the following error:

Any suggestions on how I should call the SelectCategoryViewController for the selected language?

you have... somewhere in your code.. substringWithRange / NSRange? stackoverflow.com/a/6515336/1702413 — TonyMkenu
I am using it in the set up of the first view, but it does not crash before I localize the xib file (i.e. the nib). So I do not think that is the problem. It is as if it cannot find the localized file. Yet, when I have created a simple project with this same xib file but localized, it runs fine. BTW, I am using Xcode 3.2.6. — user1653733

This line looks wrong to me:

NSBundle *myLocalizedBundle=[NSBundle bundleWithPath:[NSString stringWithFormat:[[NSBundle mainBundle]bundlePath],"en.lproj"]];

You probably meant something like this:

NSString* path= [[NSBundle mainBundle] pathForResource:@"en" ofType:@"lproj"];
NSBundle* bundle:myLocalizedBundle = [NSBundle bundleWithPath:path];
SelectCategoryViewController *viewTwo = [[SelectCategoryViewController alloc] initWithNibName:@"SelectCategoryViewController" bundle:myLocalizedBundle];

This is discussed more here: Manually loading a different localized nib in iOs

Note that this is only required if you want to do an in-app language selection. Localization should typically use the iOS device's selected language, in which case all this is much more straightforward (you simply let iOS pick the bundle for you).
