自定义 UISlider 外观

Customizing UISlider look(自定义 UISlider 外观)

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位置.来自文档:

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:

一个可拉伸的区域位于两个之间端盖区域.端盖定义图像中剩余的部分按原样，不拉伸.这可拉伸区域为 1 点宽端盖之间的区域，可以是复制以使图像出现更长.

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.

现在我遇到的问题是我的可拉伸区域需要超过 1 磅宽.(这是一种模式)不幸的是，SDK 中似乎对 1 点宽度进行了硬编码.

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.

有人知道如何解决这个问题吗?还是我必须为此从头开始编写自己的滑块?

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

我相信您必须编写自己的滑块才能做到这一点.似乎没有(公共)API 可以更改 UISlider 关于可拉伸区域的行为.

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.
