There are some features within my application that are supposed to be based on the language settings of the device where it's running.
I want to get the actual language and not some country settings. Foe example, if the language is English, I don't care if it's US, UK, Australia, etc...
I'm familiar with the NSLocale object, but it seems to relate to the Region Format setting and not to the Language setting (see screen shot below) so when I try to retrieve the language out of it using [locale displayNameForKey:NSLocaleIdentifier value:[locale localeIdentifier] I get things like English (United States) instead of English; also, I think that what I need is the Language data and not the Region Format (am I right?).
Can anyone direct me to how to retrieve the language setting?
User preferred languages are stored can be retrieved from locale as array and current language identifier is the first object in that array:
NSString *currentLanguage = [[NSLocale preferredLanguages] objectAtIndex:0];
If you want language in more readable form then use displayNameForKey:value: method of NSLocale:
NSString *langID = [[NSLocale preferredLanguages] objectAtIndex:0];
NSString *lang = [[NSLocale currentLocale] displayNameForKey:NSLocaleLanguageCode value:langID];
Try this:
NSUserDefaults* userDefaults = [NSUserDefaults standardUserDefaults];
NSArray* arrayLanguages = [userDefaults objectForKey:#"AppleLanguages"];
NSString* currentLanguage = [arrayLanguages objectAtIndex:0];
Getting language and region in Swift:
LF.log("language", NSLocale.preferredLanguages())
LF.log("locale", NSBundle.mainBundle().preferredLocalizations)
In my case I'm getting:
language: '(
"zh-Hans"
)'
locale: '(
en
)'
In Swift 4:
let currentLanguage = Locale.current.languageCode
It will give you just the language code, no country code.
Swift:
let language = NSBundle.mainBundle().preferredLocalizations[0] as NSString
Working solution:
let language = NSLocale.preferredLanguages()[0]
let languageDic = NSLocale.componentsFromLocaleIdentifier(language) as NSDictionary
//let countryCode = languageDic.objectForKey("kCFLocaleCountryCodeKey")
let languageCode = languageDic.objectForKey("kCFLocaleLanguageCodeKey") as! String
print(languageCode)
NSString * language = [[NSLocale preferredLanguages] objectAtIndex:0];
Find the solution in XCode's helper document, it wrote:
Getting the Current Language
To get the language that the app is using from the main application bundle, use the preferredLocalizations method in the NSBundle class:
NSString *languageID = [[NSBundle mainBundle] preferredLocalizations].firstObject;
Use below code to fetch Localised language without having trouble to the en-india, en-us etc..
NSString *Ph = [[[NSBundle mainBundle] preferredLocalizations] objectAtIndex:0];
In and After ios9 this code need to take in cosideration
To know the current language selected within your localizations use
[[NSBundle mainBundle] preferredLocalizations]
Example:
NSString *language = [[[NSBundle mainBundle] preferredLocalizations] objectAtIndex:0];
To get two letter word
NSString *language = [[[[NSBundle mainBundle] preferredLocalizations] objectAtIndex:0] substringToIndex:2];
Swift:
let language = NSBundle.mainBundle().preferredLocalizations.first as NSString

I would like to get language name selected by the user device.
I got language id and it's display name
NSString *langID = [[NSLocale preferredLanguages] objectAtIndex:0];
NSLog(#"langID %#",langID);
lang = [[NSLocale currentLocale] displayNameForKey:NSLocaleLanguageCode value:langID];
NSLog(#"lang %#",lang);
If I select device language as 'Chinese Traditional',the output is
langID zh-Hant-US display name 中文.
I want to display name in the English language like 'Chinese', not in the Chinese language. So my question is "Is it possible to get language name in English?" If yes then "How can we achieve it?" any suggestions would be greatly appreciated.
Thanx in Advance.
Try this :
NSString *langID = [[NSLocale preferredLanguages] objectAtIndex:0];
NSLocale *local = [NSLocale localeWithLocaleIdentifier:#"EN"];
NSString * lang = [local displayNameForKey:NSLocaleLanguageCode value:langID];
Let say I already put everything on Localizable.strings for several language. As for now I use NSLocalizedString and it return the text based on [[NSUserDefaults standardUserDefaults] objectForKey:#"AppleLanguages"] setting. Now I need to get specific string for each language.
Let say I want to put it on select language setting and show it when user press Submit button. So it will show a dialog with a message "Select this language?" on respective language that user select.
You can get any translation from any language file by loading it manually:
- (NSString *)localizedString:(NSString *)string forCountry:(NSString *)countryCode {
NSString *bundlePath = [[NSBundle mainBundle] pathForResource:#"Localizable" ofType:#"strings" inDirectory:nil forLocalization:countryCode];
NSBundle *dataBundle = [[NSBundle alloc] initWithPath:[bundlePath stringByDeletingLastPathComponent]];
return NSLocalizedStringFromTableInBundle(string, #"Localizable", dataBundle, nil); }
Does this help?
How I get now the actual system language? It seems that they put regional suffix after last dash. So before cs is now cs-DE if the language is Czech and regional setting is German. But there are some languages which don't have the suffix like GB language is en-GB but regional setting is German.
NSUserDefaults* defs = [NSUserDefaults standardUserDefaults];
NSArray* language = [defs objectForKey:#"AppleLanguages"];
NSString* preferredLang = [language objectAtIndex:0];
NSLog(#"localeIdentifier: %#", preferredLang);
Use the componentsFromLocaleIdentifier method from NSLocale class
Here is the documentation
You can do like this:
NSString* localeID = [NSLocale currentLocale].localeIdentifier;
NSDictionary* components = [NSLocale componentsFromLocaleIdentifier:localeID];
NSString* languageID = components[NSLocaleLanguageCode];
EDIT
Getting the language this way will create some issues if the language the app is currently translated in is not the device's language. Indeed,
components[NSLocaleLanguageCode] will return the device's language.
To get the app's current language, you should use [[NSBundle mainBundle] preferredLocalizations].firstObject.
To get the device's region, you can still use components[NSLocaleCountryCode]
I just run into this problem recently. According to Apple's documentation, you will get the locale id with region designator which for like [language designator]-[region designator] on iOS 9.
I found a solution if you just wanna get the locale id, you could use
[[NSBundle mainBundle] preferredLocalizations].
One more solution, If any of you like,
NSArray *languages = [[NSUserDefaults standardUserDefaults] objectForKey:#"AppleLanguages"];
NSString *currentLanguage = [languages objectAtIndex:0];
if ([[currentLanguage componentsSeparatedByString:#"-"] count] == 2)
currentLanguage = [[currentLanguage componentsSeparatedByString:#"-"] objectAtIndex:0];
// Only for chinese Language.
else if ([[currentLanguage componentsSeparatedByString:#"-"] count] == 3)
currentLanguage = [NSString stringWithFormat:#"%#-%#", [[currentLanguage componentsSeparatedByString:#"-"] objectAtIndex:0],
[[currentLanguage componentsSeparatedByString:#"-"] objectAtIndex:1]
];
"currentLanguage" Will give you your current langauge so you can use it for localise or any further use.
I am looking to get the base value or english value for a localized string from a .string file. I am showing the user in the view controller the localized string but my function uses the base value or english value. I have searched everywhere but I cannot find a solution for this.
It depends on how you show your localized string. If you are using something as below you can update code:
-(NSString *)languageSelectedStringForKey:(NSString *) key showKey: (BOOL) show
{
NSString *language = [[NSString alloc] init]
if (!show)
language = [[NSUserDefaults standardUserDefaults] stringForKey:#"Language"];
else
return key;
NSString *path = [[NSBundle mainBundle] pathForResource:language ofType:#"lproj"];
if ( !path )
return NSLocalizedString(key, nil);
return [[NSBundle bundleWithPath:path] localizedStringForKey:(key) value: #"" table:nil];
}
So where you need, you can show only key (your base value)..
I want to use iOS 7 new speech synthezis API, and my application is localized in french & english.
For this to work, 2 things have to be localized :
speech text : I put it in usual localizable.string file, and retrieve it in code using NSLocalizedString macro.
speech language : AVSpeechSynthesisVoice has to be chosen for corresponding language.
Class instanciation method is AVSpeechSynthesisVoice voiceWithLanguage:(NSString *)lang.
I'm currently using [NSLocale currentLocale].localeIdentifier as parameter for this method.
Problem : if user's device language is Portuguese, [NSLocale currentLocale] select portuguese prononciation, while text resolved by NSLocalizedString is english.
How can I know which locale is currently read by NSLocalizedString ?
Ok, I finally managed to make sense of Apple APIs :
[NSLocale currentLocale] : DOESN'T return current language picked by User in Settings > General > international, but returns the region code selected by user in same screen.
[NSLocale preferredLanguages] : This list DOES give device language, it's the first string in this list
[[NSBundle mainBundle] preferredLocalizations] return language bundle resolved by application. I guess this is what NSLocalizedString uses. It only has 1 object in my case, but I wonder in which cases it can have more than one.
[AVSpeechSynthesisVoice currentLanguageCode] returns the system predefined language code.
[AVSpeechSynthesisVoice voiceWithLanguage:] class instanciation method needs complete language code : with language AND region. (e.g. : passing #"en" to it will return nil object, it needs #"en-US", or #"en-GB"... )
[AVSpeechSynthesisVoice currentLanguageCode] gives default voice, determined by OS.
So this is what my final code looks like
// current user locale (language & region)
NSString *voiceLangCode = [AVSpeechSynthesisVoice currentLanguageCode];
NSString *defaultAppLang = [[[NSBundle mainBundle] preferredLocalizations] firstObject];
// nil voice will use default system voice
AVSpeechSynthesisVoice *voice = nil;
// is default voice language compatible with our application language ?
if ([voiceLangCode rangeOfString:defaultAppLang].location == NSNotFound) {
// if not, select voice from application language
NSString *pickedVoiceLang = nil;
if ([defaultAppLang isEqualToString:#"en"]) {
pickedVoiceLang = #"en-US";
} else {
pickedVoiceLang = #"fr-FR";
}
voice = [AVSpeechSynthesisVoice voiceWithLanguage:pickedVoiceLang];
}
AVSpeechUtterance *mySpeech = [[AVSpeechUtterance alloc] initWithString:NSLocalizedString(#"MY_SPEECH_LOCALIZED_KEY", nil)];
frontPicUtterance.voice = voice;
This way, a user from NewZealand, Australien, GreatBritain, or Canada will get the voice that correspond most to his usual settings.
Vinzzz's answer was a great start -- I've generalised it to work with any language:
NSString *language = [[[NSBundle mainBundle] preferredLocalizations] objectAtIndex:0];
NSString *voiceLangCode = [AVSpeechSynthesisVoice currentLanguageCode];
if (![voiceLangCode hasPrefix:language]) {
// the default voice can't speak the language the text is localized to;
// switch to a compatible voice:
NSArray *speechVoices = [AVSpeechSynthesisVoice speechVoices];
for (AVSpeechSynthesisVoice *speechVoice in speechVoices) {
if ([speechVoice.language hasPrefix:language]) {
self.voice = speechVoice;
break;
}
}
}
