如何让 UISlider 变厚? [英] How to make UISlider thicker?

问题描述

我想创建一个非常厚的水平方向UISlider.我知道让它变长很容易，但是我如何使轨迹(以及可以注册触摸事件的区域)变厚?

I want to create a really thick horizontally oriented UISlider. I know it is easy to make it longer, but how do I make the track (and therefore the area in which touch events can be registered) thicker?

推荐答案

将 UISlider 子类化，然后进行以下修改:

Subclass the UISlider and then make this modification:

- (CGRect)trackRectForBounds:(CGRect)bounds
{
    return bounds;
}

(我刚刚在 UICatalog -- 这是一组非常好的 Apple 示例代码 -- 并且效果很好).

(I just tried this out in UICatalog -- which is a very nice set of Apple sample code -- and it works perfectly great).
