如何在 UIAlertController 中以编程方式更改特定按钮文本颜色

How to change the specific button text colour programmatically in the UIAlertController

我想将 UIAlertController 中 "Cancel" 按钮的颜色更改为橙​​色,并保持 "Log Out" 按钮的颜色不变。我在下面附上了警报控制器的屏幕截图和代码。

警报视图代码

alert = UIAlertController(title: "", message: "Are you sure you want to log out?", preferredStyle: UIAlertControllerStyle.Alert)
    alert.view.tintColor = UIColor.blackColor()
    alert.addAction(UIAlertAction(title: "Log out", style: UIAlertActionStyle.Cancel, handler:{ (UIAlertAction)in

        println("Log Out button clicked.")

        prefs.setBool(false, forKey: "Isloggedin")
        NSUserDefaults.resetStandardUserDefaults()
        prefs.setBool(true, forKey: "IsEmail")
        prefs.setObject(email, forKey: "loggedemail")
        prefs.synchronize()
        let mainview = self.storyboard?.instantiateViewControllerWithIdentifier("mainscreen") as! mainViewController

        self.navigationController?.pushViewController(mainview, animated: true)
    }))

    //alert.view.tintColor = UIColor.yellowColor()
    alert.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Default, handler:{ (UIAlertAction)in
        println("Cancel button clicked.")
    }))

    self.presentViewController(alert, animated: true, completion: {
        println("completion block.")


    })

我已经创建了一个自定义提醒,我们可以根据需要在其中进行更改。
