No this is not possible - user can only change their language in the settings.

However you can give the user an "English" keyboard if you choose (or ask them their preference) 

you do this using: <code>UIKeyboardTypeASCIICapable</code>

You can change keyboard directly on the keyboard by pressing "globe icon" on the bottom row. 

First, you have to enable those language for input in Settings. Then pressing the globe button on the keyboard would toggle between those languages.

blocks|key|252963|text|例如，这似乎可以更改为希腊语键盘：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|252964|[[NSUserDefaults+standardUserDefaults]+setObject:[NSArray+arrayWithObjects:@"el",+nil]+

This seems to work to change, for instance, to a Greek keyboard:

<pre><code>[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObjects:@"el", nil] 
 forKey:@"AppleLanguages"]; 

[[NSUserDefaults standardUserDefaults] synchronize]; 
</code></pre>

I know it is old question, but here it is my way to change keyboard language. 

Thank to @the4kman for the mark: this way can change current keyboard only to those which were added in Settings.

Swift 3:

<pre><code>class CustomTextField: UITextField {

 private func getKeyboardLanguage() -&gt; String? {
 return "en" // here you can choose keyboard any way you need
 }

 override var textInputMode: UITextInputMode? {
 if let language = getKeyboardLanguage() {
 for tim in UITextInputMode.activeInputModes {
 if tim.primaryLanguage!.contains(language) {
 return tim
 }
 }
 }
 return super.textInputMode
 }

}
</code></pre>

Declaration:

<pre><code>@IBOutlet var yourTextField:cTextField!;
</code></pre>

Use:

<pre><code>yourTextField.languageCode = "ru";
</code></pre>

Class cTextField:

<pre><code>class cTextField: UITextField {

 // ru, en, ....
 var languageCode:String?{
 didSet{
 if self.isFirstResponder{
 self.resignFirstResponder();
 self.becomeFirstResponder();
 }
 }
 }

 override var textInputMode: UITextInputMode?{
 if let language_code = self.languageCode{
 for keyboard in UITextInputMode.activeInputModes{
 if let language = keyboard.primaryLanguage{
 let locale = Locale.init(identifier: language);
 if locale.languageCode == language_code{
 return keyboard;
 }
 }
 }
 }
 return super.textInputMode;
 }
}
</code></pre>

blocks|key|253032|text|都是很棒的答案。但在Swift中，您可以在扩展中覆盖父类(UIResponder)中定义的方法和变量。所以没有必要进行子类化。用更快的一行程序替换for循环也很不错。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|253033|public+extension+UITextField+{++
++++override+var+textInputMode:+UITextInputMode?+{
++++++++return+UITextInputMode.activeInputModes.filter+{+$0.primaryLanguage+==+"emoji"+}.first+??+super.textInputMode
++++}
}|code-block|syntax|javascript|253034|而不是"emoji“，可能是类似Utils.currentAppLanguage的东西。|253035|entityMap^0|T|B|21|3|0|0|G|O|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@]|E|$]]|$1|M|3|-4|5|6|7|X|8|@]|D|@]|E|$]]]|N|$]]

All great answers. But in Swift you can override methods and variables defined in parent class (<code>UIResponder</code>) in an extension. So it's not necessary to subclass. And it's nice to replace the <code>for</code> loop with a more swift like one-liner.

<pre><code>public extension UITextField { 
 override var textInputMode: UITextInputMode? {
 return UITextInputMode.activeInputModes.filter { $0.primaryLanguage == "emoji" }.first ?? super.textInputMode
 }
}
</code></pre>

Instead of "emoji" probably will be something like <code>Utils.currentAppLanguage</code>

I am trying to provide a different language support on my iOS 5.x application whenever native Keyboard is opened. Provide this language in native keyboard programmatically. Could someone guide me how can i support it? I saw a carbon framework, but looks like its for Mac apps.

Thanks.

iPhone: Change Keyboard language programmatically

每当打开本机键盘时，我都会尝试在我的iOS 5.x应用程序上提供不同的语言支持。以编程方式在本机键盘中提供此语言。有人能指导我怎样才能支持它吗？我看到了一个carbon框架，但看起来像是针对Mac应用程序的。谢谢。
