localizable.strings not working with Arabic string - ios

Question

I created a Localizable.strings file in XCode and then 2 languages in it.(english + Arabic )
I filled up these files with the language translations, but the just show translation in english, when I start with Arabic the key appear!
in my code :
NSLocalizedString("title", comment: "")
Localizable.strings(english)
"title" = "Error" ;
Localizable.strings(Arabic)
"title" = "خطأ" ;

Answer 1

I careated sample one and tried in Objective C.I got it.
I set "title" = "خطأ" in Arabic Localization files
"title" = "عنوان";
Now I have to change English to Arabic.
First I set the design in storyboard
Then Click Project.Choose Localization in Info
If you click the +(Below Localization) it shows the pop up view
Now choose Arabic.When click Arabic it shows window.You should click finish.
We need to create the string file for the localization now.I set string file name as LocalizationArabic
Once you create the String file it looks like below.
Then click File Inspector when pressing LocalizationArabic string file.Now click the Localization.It shows Empty Check box Arabic and English like below.
Here we must check the check box.Also when we check the check box the LocalizationArabic folder creates with three string files like below
Then I entered the language which I want to translate from English to Arabic in string file.
Finally I created the Header file for the Localization Language
The Header file name is LanguageHeader.It looks like below.
Now the code part starts here
First the Localization class of NSObject class
Localization.h
#import <Foundation/Foundation.h>
#import "LanguageHeader.h"
#interface Localization : NSObject
+(Localization *)sharedInstance;
+(NSString*) strSelectLanguage:(int)curLang;
+(NSString*) languageSelectedStringForKey:(NSString*) key;
#end
Localization.m
#import "Localization.h"
int currentLanguage,selectedrow;
#implementation Localization
+(Localization *)sharedInstance
{
static Localization *sharedInstance = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
sharedInstance = [[Localization alloc] init];
});
return sharedInstance;
}
+(NSString*) strSelectLanguage:(int)curLang{
if(curLang==ARABIC){
[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:#"ar", nil]forKey:#"AppleLanguages"];
}
else{
[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:#"en", nil]forKey:#"AppleLanguages"];
}
[[NSUserDefaults standardUserDefaults] synchronize];
currentLanguage=curLang;
NSString *strLangSelect = [[[NSUserDefaults standardUserDefaults]objectForKey:#"AppleLanguages"] objectAtIndex:0];
return strLangSelect;
}
+(NSString*) languageSelectedStringForKey:(NSString*) key
{
NSString *path;
NSString *strSelectedLanguage = [[[NSUserDefaults standardUserDefaults]objectForKey:#"AppleLanguages"] objectAtIndex:0];
//When we check with iPhone,iPad device it shows "en-US".So we need to change it to "en"
strSelectedLanguage = [strSelectedLanguage stringByReplacingOccurrencesOfString:#"en-US" withString:#"en"];
if([strSelectedLanguage isEqualToString:[NSString stringWithFormat: #"en"]]){
currentLanguage=ENGLISH;
selectedrow=ENGLISH;
path = [[NSBundle mainBundle] pathForResource:#"en" ofType:#"lproj"];
}
else{
currentLanguage=ARABIC;
selectedrow=ARABIC;
path = [[NSBundle mainBundle] pathForResource:#"ar" ofType:#"lproj"];
}
NSBundle* languageBundle = [NSBundle bundleWithPath:path];
NSString* str=[languageBundle localizedStringForKey:key value:#"" table:#"LocalizationArabic"];
return str;
}
#end
Then ViewController.h
#import <UIKit/UIKit.h>
#import "Localization.h"
#interface ViewController : UIViewController{
Localization *localization;
}
#property (strong, nonatomic) IBOutlet UILabel *lblTitle;
- (IBAction)actionChangeLanguageToArabic:(id)sender;
#end
ViewController.m
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
#synthesize lblTitle;
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
localization = [Localization sharedInstance];
lblTitle.text = [Localization languageSelectedStringForKey:#"title"];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (IBAction)actionChangeLanguageToArabic:(id)sender {
[Localization strSelectLanguage:ARABIC];
lblTitle.text = [Localization languageSelectedStringForKey:#"title"];
}
#end
Above code works perfectly.
