它改变了段颜色。请帮助我..

Answer 1

无法在UISegmentedControl中设置所选片段标题的自定义颜色。 UIControlState中的forState:用于设置正常和选定状态的段文本属性。

来自您的代码：

[[UIsegmentControl.subviews objectAtIndex:segment.selectedSegmentIndex] setTintColor:[UIColor redColor]];

试用此代码：

[segmnt_cntrl setTitleTextAttributes:@{NSFontAttributeName:[UIFont fontWithName:@"Arial" size:16.0],
                                                          NSForegroundColorAttributeName:[UIColor redColor],
                                                          NSShadowAttributeName:shadow}
                                                         forState:UIControlStateNormal];

将segmnt_cntrl替换为Segment Cotrol的对象。试试这个，它可以帮助你实现你的全部目标。

如果你需要更改iOS 7中突出显示的片段的文字颜色，这里有一个解决方案（花了我一段时间才找到，但是thanks to this post）：

[[UISegmentedControl appearance] setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor colorBlack]} forState:UIControlStateSelected];

更新了Swift 4.1

# use, i.e. don't skip the full RPATH for the build tree
SET(CMAKE_SKIP_BUILD_RPATH  FALSE)

# when building, don't use the install RPATH already
# (but later on when installing)
SET(CMAKE_BUILD_WITH_INSTALL_RPATH FALSE)

# the RPATH to be used when installing
SET(CMAKE_INSTALL_RPATH "${FCL_SOURCE_DIR}/libs")

# don't add the automatically determined parts of the RPATH

Swift 3.1

UISegmentedControl.appearance().setTitleTextAttributes([NSAttributedStringKey.foregroundColor: UIColor.red], for: .selected)

对于早期的Swift版本：

UISegmentedControl.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.red as Any], for: .selected)

Answer 4

在UISegmentedControl中没有标准API来设置单个段的文本属性。您可以使用未经推荐的方法挖掘分段控件的视图层次结构，找到所需的UILabel（如果有）并设置该标签的属性。更好的方法是查找（或编写）模拟UISegmentedControl的自定义控件，并允许以您需要的方式自定义单个段。

编辑：

实际上，我从错误的角度来看待这个问题。我的答案是基于尝试为特定的段索引设置属性。但事实上，这可以通过设置UIControlStateSelected状态的文本属性来实现。对不起，感到困惑。
