Question

Xcode9.2, iOS 11, swift

I'm working on a project where user have to enter some text using Keyboard. User can use English & Japanese keyboard. now, when i start typing using English keyboard it works good no problem at all. but when i change keyboard to Japanese and start entering a same character multiple times. it shows selected text in UITextField .

here is my UITextField setup,

    self.tf.font = self.font
    self.tf.textAlignment = .center
    self.tf.returnKeyType = .done
    self.tf.inputAccessoryView = nil
    self.tf.text = " "
    self.tf.tintColor = UIColor.clear
    self.tf.textColor = UIColor.darkGray

要更改UITextField的文本选择颜色，只需更改tint color属性：

textField.tintColor = UIColor.purple
