LAContext change the name of the UIAlertController button

Question

I have included TouchID in my application using LAContext , for example:

However, I want to change the name of the button name from "Enter Password" to enter "Enter Security Code" (or something like that), for example:

How do I change the name of this button?

Here is the LAContext documentation and here is my code:

 var touchIDContext = LAContext() if touchIDContext.canEvaluatePolicy(LAPolicy.DeviceOwnerAuthenticationWithBiometrics, error: &msgError) { touchIDContext.evaluatePolicy(.DeviceOwnerAuthenticationWithBiometrics, localizedReason: touchIDMessage) { (success: Bool, error: NSError!) -> Void in if success { println("Success") } else { println("Error: \(error)") } } } 

Answer 1

Set the localizedFallbackTitle property:

Objective-C:

 LAContext *context = [[LAContext alloc] init]; context.localizedFallbackTitle = @"YOUR TEXT HERE"; 

Swift:

 var touchIDContext = LAContext() context.localizedFallbackTitle = "YOUR TEXT HERE" 

Answer 2

From Apple documentation localizedCancelTitle is available for iOS 10

 // Fallback button title. // @discussion Allows fallback button title customization. A default title "Enter Password" is used when // this property is left nil. If set to empty string, the button will be hidden. @property (nonatomic, nullable, copy) NSString *localizedFallbackTitle; // Cancel button title. // @discussion Allows cancel button title customization. A default title "Cancel" is used when // this property is left nil or is set to empty string. @property (nonatomic, nullable, copy) NSString *localizedCancelTitle NS_AVAILABLE(10_12, 10_0);
