UISegmentedControl 在每个分段索引中有多个字符串

Question

我试图在每个分段索引中显示 2 个文本字符串，而不是一个长文本。当前视图看起来像这样

我想要 "Repeat task" 和 "One time task" 下面的另一个字符串，如图中红线所示。目前我的模型是

class SegmentedControlItems:NSObject{
    let title: String
    let subtitle: String

    init(title:String, subtitle:String) {
        self.title = title
        self.subtitle = subtitle
    }
}

我的 table 视图 header 中的代码是

        let items:[SegmentedControlItems] = {
            let item1 = SegmentedControlItems(title: "Repeat task", subtitle: "2 left")
            let item2 = SegmentedControlItems(title: "One time task", subtitle: "3 left")
            return [item1, item2]
        }()

        let segmentedControl: UISegmentedControl = {

            let segmentedControl = UISegmentedControl(items: items.map({
                [=11=].title
            }))
            segmentedControl.tintColor = UIColor(red:0.44, green:0.75, blue:0.27, alpha:1.0)
            segmentedControl.selectedSegmentIndex = 0
            segmentedControl.translatesAutoresizingMaskIntoConstraints = false
            return segmentedControl
        }()
        headerView.addSubview(segmentedControl)

我在 swift4 中以编程方式创建所有视图。有人可以帮忙吗？

用 Objective C here

找到了类似的东西

对于 iOS 11 和 Swift 4:

对于多行，试试这个。可能对你有帮助。

UILabel.appearance(whenContainedInInstancesOf: [UISegmentedControl.self]).numberOfLines = 0

for i in 0..<items.count {

     var str = items[i].title
     if items[i].subtitle != "" {
       str += "\n\(items[i].subtitle)"
     }

     let myMutableString = NSMutableAttributedString(string: str, attributes: [:])
     myMutableString.addAttribute(NSAttributedStringKey.foregroundColor, value: UIColor.red, range: NSRange(location:items[i].title.characters.count + 1, length:items[i].subtitle.characters.count))
     myLabel[i].attributedText = myMutableString
     mySegment.setTitle(myMutableString.string, forSegmentAt: i)
}

Output look like this (In UILabel its working, but not in UISegmentControl) Hope someone will do that:

UISegmentedControl with multiple strings in each segmented index
