我们有一个UILabel隐藏的登录屏幕,最初用于表示用户退出应用程序时的消息.

当在iOS中打开VoiceOver并且用户尝试从应用程序注销时,理想情况下应该读出注销消息标签.相反,它会读出登录屏幕的密码文本字段.

注销按钮的操作具有以下实现代码.

let loginStoryboard = UIStoryboard(name: "Login", bundle: nil)
        let loginViewController = loginStoryboard.instantiateInitialViewController() as! LoginViewController
        loginViewController.modalPresentationStyle = UIModalPresentationStyle.CurrentContext
loginViewController.logOut = true
self.presentViewController(loginViewController, animated: true, completion:nil)

注销指示器设置为显示注销消息标签. LoginViewController viewDidLoad码.

if(!logOut){
            self.logOutMsg.hidden = true
}else{
            self.logOutMsg.text = NSLocalizedString("LoggedOutMsg", comment: "Logged out message")
            self.logOutMsg.hidden = false
}

登录屏幕字段是故事板中启用的辅助功能.

行为不一致:有时会读取注销消息标签,有时会读出密码文本字段.每当VoiceOver读取密码文本字段时,我都会在控制台日志中看到错误.
