How to compare Localized string with the string from the database? - ios

I have a to compare a string with the string from the db.
var variableFromDB = "test"
if "test" == variableFromDB{
print("Success")
}
It works fine in the English Language. I don't know how to compare it in the arabic language. Is the need to check in arabic language also. Please tell me know to check it.

In general it's a bad idea for your code to make decisions based on display strings. That goes double for display strings.
If your primary audience is Arabic-speaking, you could make your development language Arabic and then localize for other languages as needed.
In any case, I would suggest using a set of fixed strings as keys, and then calling NSLocalizedString(_:tableName:bundle:value:comment:) or one of it's variants to fetch a display string. Example:
Put this code somewhere central so the keys can be shared:
let screen1Prompt = "screen1Prompt"
Then when you need a localized string for display:
let prompt = NSLocalizedString(screen1Prompt)
Where the actual prompt string might be "Please select the date for your payment." in English, Arabic, etc.
Then if you need to match something in your database, look it up using the unlocalized key, not the localized display string.
That way if you later change the display string, your code still works.

var language: String
UserDefaults.standard.set("AE", forKey: "Apple") // manually set language
UserDefaults.standard.synchronize()
self.language = UserDefaults.standard.object(forKey: "Apple")as! String
// self.language = Locale.current.languageCode // your device language
extension String {
func stringlocalized(lang:String) ->String {
let path = Bundle.main.path(forResource: lang, ofType: "lproj")
let bundle = Bundle(path: path!)
return NSLocalizedString(self, tableName: nil, bundle: bundle!, value: "", comment: "")
}}
// Check You Localization string from your current language
let str = “ test”.localized(lang: self.language! )
if str ==variableFromDB
{ // Your logic here
}

Set default language with localization

Is it possible to use a default language for the localization? for example if a key is not found for one language, than the system will look at it automatically in the English language? If it's not possible to do it automatically, would it be possible to do it manually? look for a key in the current language, if not found then force the system to look at it in the English language? In my current app, when a key is not set, the key name is returned.
Here is a method that do what you want (I didn't find an "official" way to do it).
func localizedString(_ key: String) -> String? {
let localeString = NSLocalizedString(key, comment: "")
// Base can be changed by en or the default language of your choice
if localeString == key,
let path = Bundle.main.path(forResource: "Base", ofType: ".lproj"),
let baseBundle = Bundle(path: path) {
return baseBundle.localizedString(forKey: key, value: nil, table: nil)
}
return nil
}

Wrong language code swift

I set the language of the simulator to French. To check the language code, I used a couple of solutions:
let lang = NSLocale.autoupdatingCurrent.languageCode
print(lang)
let pre = Locale.preferredLanguages[0]
print(pre)
The result are:
Optional("en")
fr-US
What I expected to get is:
fr
How can I achieve that?
Try below code,
let requiredString = pre.components(separatedBy: "-").first ?? pre //fr
/*if pre.contains("-"), then requiredString = before("-") else requiredString = pre*/
print(Locale.components(fromIdentifier: Locale.preferredLanguages[0])["kCFLocaleLanguageCodeKey"]!)
this will print language code only.
If you want the Language instead of the Language_Region, then I suggest to take the sub string before the _ from the string to neglect the Region.
(If the string contains no _ then take the entire string since it doesn't contain the region in it)

Localizable strings from JSON runtime on iOS

I have user localizable strings for the strings used in storyboard or source files which are fixed. These are defined in files like Localizable.string (Spanish), Localizable.string (German) etc. But I have a requirement where these strings can keep changing. These strings are received as a response to REST API call. My question is how can I use it.
Current code is let text = NSLocalizedString("Some string", comment: "")
Where NSLocalizedString looks for Localizable.string file. How can I make NSLocalizedString look for localized words from my custom dictionary/Json?
Try this
First you need to copy that files in document directory .
Get Localised Label
let localisedString = self.getLocalizatioString(key: "your key", stringFileName: "test.strings") //
Function
func getLocalizatioString(key : String?, stringFileName : String ) -> String {
let doumentDirectoryPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString
let destinationPath = doumentDirectoryPath.appendingPathComponent(stringFileName)
let dict = NSDictionary.init(contentsOfFile: destinationPath)
return (dict?.object(forKey: key!) as? String)!
}
Output
In String file

iOS Base localization was not used for missing key

Let's say I have this 2 strings files in my project:
Localizable.strings (Base)
"hello_key" = "Hello";
"bye_key" = "Goodbye";
and
Localizable.strings (Chinese Traditional)
"hello_key" = "您好";
And I use the following code to localize the "hello" string
NSLocalizedString("hello_key", comment: "")
It works fine for "hello_key", but if I use "bye_key" in my iPhone with phone language set to Tradition Chinese, I get "bye_key" as the localized string.
In another word, the Base localization was not used. Is it possible to show the Base English "GoodBye" in this case?
Thanks.
This is the case of unsupported phrase, because your did not translate completely for Traditional Chinese.
Apple will not fallback to the base language, but simply return the key. This is just how it behaves. I wrote more about it in my blog.
You have to write a custom NSLocalizedString like this (the example uses en as the fallback language):
public func LS(_ key: String) -> String {
let value = NSLocalizedString(key, comment: "")
if value != key || NSLocale.preferredLanguages.first == "en" {
return value
}
// Fall back to en
guard
let path = Bundle.main.path(forResource: "en", ofType: "lproj"),
let bundle = Bundle(path: path)
else { return value }
return NSLocalizedString(key, bundle: bundle, comment: "")
}

How to get detailed language of device in swift

I have a database on the server that contains all the languages keywords that I use inside my applications and these languages could be changed any time.
In the language table of database there is column for Language (id , key, value, lang).
In the android application I read the language from device and it returns for example en-GB or en-US.
But in the iOS application I can't get the language like the above example , It always returns just the language (en , es, fr).
So I can't query to database to get the language specified keywords on the iOS application. Because the languages on the database is en-GB, en-US style.
var langId: String? = NSLocale.preferredLanguages().first as? String
How can I get the language with more details ?
Start with the currentLocale() and ask questions about it. For example:
let lang = NSLocale.currentLocale().localeIdentifier
Or, at a finer level of granularity:
let langId = NSLocale.currentLocale().objectForKey(NSLocaleLanguageCode) as! String
let countryId = NSLocale.currentLocale().objectForKey(NSLocaleCountryCode) as! String
let language = "\(langId)-\(countryId)" // en-US on my machine
Swift 3 does not have an NSLocaleCountryCode, this is replaced by regionCode
https://developer.apple.com/reference/foundation/nslocale.key/1417845-countrycode
solution in Swift 5:
let langCode = Locale.current.languageCode ?? ""
let regionCode = Locale.current.regionCode ?? ""
let language = "\(langCode)-\(regionCode)"
Another solution is NSLocale.current.identifier
This will return e.g. en_us
You could replace _ for -. it will look like this: NSLocale.current.identifier.replacingOccurrences(of: "_", with: "-")
No need an extra effort, just use the following as per your requirement.
Locale.current.identifier //en_US
Locale.current.collatorIdentifier //en-US
For Swift 4 use instead:
NSLocale.current.identifier //Output: en-US, pt-BR
Swift 5
Locale.currentLanguage.rawValue
just use this code line can solve:
let identifier = Locale.current.identifier
