ios - 图像图标未显示在 swift 文本框的右侧

Question

1. 图像位于文本框右侧，但图像填充不正确:

   let imageView = UIImageView();
   let imageDown = UIImage(named: "down-arrow.png");
   imageView.image = imageDown;
   imageView.frame = CGRect(x: 0, y: 0, width: iconWidth, height: iconHeight)
   pickerSelect.rightViewMode = .always
    pickerSelect.rightView = imageView
   

2. 文本框中的右侧没有填充。如何设置图像的内边距。

Answer 1

保持简单:

txtField.rightViewMode = .always
txtField.rightView = UIImageView(image: UIImage(named: "down-arrow.png"))
