改变 UIStepper 的外观

问题描述

UIStepper 非常方便，但我想改变它的外观，我需要自定义图标而不是加号和减号，并且我想改变控件的颜色.我怎样才能做到这一点?提前致谢！

UIStepper is very convenient but I want to change the appearance of it, I need to have customized icon not the plus and minus and also I want to change the color of the control. How can I achieve this? Thanks in advance!

推荐答案

你目前不能这样做.如果要自定义图标，则必须编写自定义 UIControl 对象.

You cannot presently do this. You'll have to write a custom UIControl object if you want to customize the icons.

来自 UIStepper 类参考，您唯一可以更改的参数是

From the UIStepper Class Reference, the only parameters you can change are

  continuous  property
  autorepeat  property
  wraps  property
  minimumValue  property
  maximumValue  property
  stepValue  property

  value  property

您不能自定义图标.

不过，由于它是UIView的子类，你可以尝试改变backgroundColor.

However, since it is a subclass of UIView, you can try changing the backgroundColor.
