UISearchBAR scopeBar tintColor [英] UISearchBAR scopeBar tintColor

问题描述

是否有人设法为 UISearchBar 的范围栏部分着色，它有一个 tintColor 属性，但设置它不会影响附加的范围栏 UISegmentedControl.我有一个把手可以给它上色，但似乎不起作用，即:

Has anyone managed to color the scopebar portion of a UISearchBar, it has a tintColor property but setting it does not affect the attached scopebar UISegmentedControl. Ive got a handle on the bar to tint it but doesnt seem to work ie:

for (id subview in searchBar.subviews){
  if([subview isMemberOfClass:[UISegmentedControl class]]){
     UISegmentedControl *scopeBar=(UISegmentedControl *) subview;
    scopeBar.tintColor=UIColorFromRGB(0x990066);
 }
}

干杯，尼尔

推荐答案

这很有趣，原来范围栏是一个有点自定义的分段控件.

This is interesting, turns out the scope bar is a somewhat customised segmented control.

来自文档:UISegmentedControl 仅在分段控件的样式为 UISegmentedControlStyleBar 时使用此属性.

From the docs: UISegmentedControl uses this property only if the style of the segmented control is UISegmentedControlStyleBar.

现在范围栏分段控件看起来像 UISegmentedControlStyleBar 但不是，它是一些未记录的样式:

Now the scope bar segmented control looks like UISegmentedControlStyleBar but isn't, it's some undocumented style:

NSLog(@"scope bar style is %d", scopeBar.segmentedControlStyle);
> scope bar style is 7

你可以试试这个，它确实设置了色调，但看起来像屁股:

You can try this, which does actually set the tint but it looks like arse:

[scopeBar setSegmentedControlStyle:UISegmentedControlStyleBar];
[scopeBar setTintColor: UIColorFromRGB(0x990066)];
> scope bar style is 2

在内部有一些实例变量会影响此:_segementedControlFlags.style 和 _barStyle 但除非绕过受制裁的 API，否则您无法破解它们.

Internally there are some instance variables influencing this: _segementedControlFlags.style and _barStyle but you cannot hack those unless you bypass the sanctioned API.

最好的做法是向 Apple 提出该问题，并希望他们在未来的版本中包含修复程序.

The best course of action is to raise it with Apple and hope they include a fix in a future release.
