自定义UISlider外观 [英] Customizing UISlider look

问题描述

要自定义UISlider的视觉外观，您可以设置缩略图和轨道图像。部分轨道图像被拉伸到适当的。从文档：

To customize the visual look of a UISlider you can set the thumb and track images. Part of the track images gets stretched to the appropriate with. From the documentation:

可伸展区域位于两个
端盖区域之间。端盖定义
的图像的部分保持
为原样，不拉伸。
可伸展区域是一个1磅宽的
区域之间的端帽，可以
复制，使图像出现
更长。

A stretchable region sits between two end cap regions. The end caps define the portions of the image that remain as is and are not stretched. The stretchable region is a 1-point wide area between the end caps that can be replicated to make the image appear longer.

现在我的问题是我的可伸展区域需要超过1点宽。 （这是一个模式）不幸的是，1点宽度似乎是硬编码在SDK中。

Now the problem I have is that my stretchable region needs to be more than 1-point wide. (It's a pattern) Unfortunately the 1-point width seems to be hard coded in the SDK.

任何人有想法如何解决这个问题？或者我将从头开始编写自己的滑块吗？

Anyone having an idea how to work around this? Or will I have to write my own slider from scratch for this?

推荐答案

我相信你必须编写自己的滑块来做。似乎没有（公共）API来改变UISlider关于可伸展区域的行为。

I believe you'll have to write your own slider to do that. There seems to be no (public) API to change UISlider's behavior regarding the stretchable region.
