In a nutshell :

Localize your application

Override NSLocalizedString

NSLocalizedString(key,
comment)

MYLocalizedString(key,
comment)

#define
MYLocalizedString(key, comment) [[MYLocalizationSystem sharedInstance] localizedStringForKey:(key) value:(comment)];

MYLocalizationSystem

Set user language

[[MYLocalizationSystem
sharedInstance] setLanguage:@"fr"];

- (void)setLanguage:(NSString *)lang
{
NSString *path = [[NSBundle mainBundle] pathForResource:lang ofType:@"lproj"];
if (!path)
{
_bundle = [NSBundle mainBundle];
NSLog(@"Warning: No lproj for %@, system default set instead !", lang);
return;
}

_bundle = [NSBundle bundleWithPath:path];
}

Return localized string

- (NSString *)localizedStringForKey:(NSString *)key value:(NSString *)value
{
// bundle was initialized with [NSBundle mainBundle] as default and modified in setLanguage method
return [self.bundle localizedStringForKey:key value:value table:nil];
}
