Iphone sdk - Get Localized text from specific localized.strings file

Question

Is it possible to get a localized string from a specific localized.strings file, rather than from the system chosen localized.strings file, ONLY ONE TIME. I do not need to change all the localized texts, only some of them.

What I want to do is to have localized strings defined from language preferences but also localization. So that a user from Brazil location with English lang will get the application in English but some texts will be specific to the region so I want them in Portuguese.

But a user from Argentina, also with iPhone in English will get the application in English but some texts will be in Spanish.

Something like

 NSLocalizedStringFromTable("string.key","pt_BR",nil)

I thought that sending that to the table parameter would work but it didn't as it looks for the name of the file and not for the language.

You can use the different bundle to choosing specific language:

NSString * path = [[NSBundle mainBundle] pathForResource:@"pt-PT" ofType:@"lproj"];
NSBundle * bundle = nil;
if(path == nil){
    bundle = [NSBundle mainBundle];
}else{
    bundle = [NSBundle bundleWithPath:path];
}
NSString * str = [bundle localizedStringForKey:@"a string" value:@"comment" table:nil];

Swift 3.0:

extension Bundle {
    static let base: Bundle = {
        if let path = Bundle.main.path(forResource: "Base", ofType: "lproj") {
            if let baseBundle = Bundle(path: path) {
                return baseBundle
            }
        }
        return Bundle.main
    }()
}

let localizedStr = Bundle.base.localizedString(forKey: key, value: nil, table: table)
