我已经使用LAContext将TouchID合并到我的应用程序中,如下所示:
但是,我想要从“输入密码”更改按钮标题的名称,以输入“输入安全代码”(或类似的东西),如下所示:
如何更改按钮标题?
这是LAContext documentation,这是我的代码:
- 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)")
- }
- }
- }
解决方法
设置localizedFallbackTitle属性:
Objective-C的:
- LAContext *context = [[LAContext alloc] init];
- context.localizedFallbackTitle = @"YOUR TEXT HERE";
迅速:
- var touchIDContext = LAContext()
- context.localizedFallbackTitle = "YOUR TEXT HERE"
