Summary:
In an iOS application that is localized in multiple languages where there are Localizable.strings files for English, Dutch and Dutch (Belgium), when Dutch is set as the device language and Belgium as the country, the Dutch strings are used and NOT the Dutch-Belgium strings.

The Locale is set:
NSLocale *locale = [NSLocale currentLocale];
NSString *language = [locale displayNameForKey:NSLocaleIdentifier value:[locale localeIdentifier]];
NSLog(@"language %@", language);
> language Nederlands (België)

But NSLocalizedString get the Dutch resource, not the Dutch (Belgium) one

Steps to Reproduce:
1) Create a localized app with the above language string resources, build and install on Device
2) Go to Settings App and select Dutch as Language and Belgium as Region
3) Open the app

Expected Results:
When Dutch (Belgium) is selected the appropriate resources should be used for NSLocalizedString.

Actual Results:
The Dutch resources are used for NSLocalizedString

Regression:
The problem does not occur when first selecting Netherlands as Language and then selecting Vlaams (Flemish).
