Question

在表格视图中，我可以通过这样做选择多个数据源 if（tableView == self.tableOutletName）

但是当谈到分段我该怎么办？这里我有3个segmentControls

@IBOutlet weak var segmentView1: SJFluidSegmentedControl!

@IBOutlet weak var segmentView2: SJFluidSegmentedControl!

@IBOutlet weak var segmentView3: SJFluidSegmentedControl!

我将如何重写此功能

func numberOfSegmentsInSegmentedControl(_ segmentedControl: SJFluidSegmentedControl) -> Int 

{

    return 6

}

这样我就可以分别给每个段控制6个4和3个段。

此处更新的代码我遇到致命错误

Answer 1

您可以switch：

switch segmentedControl {
    case segmentView1: return 6
    case segmentView2: return 4
    case segmentView3: return 3
    default: return 0
}

请记住将self设置为所有分段控件的数据源！

Answer 2

在数据源方法中使用switch / if语句，如下所示：

func numberOfSegmentsInSegmentedControl(_ segmentedControl: SJFluidSegmentedControl) -> Int {
    switch segmentedControl {
    case segmentView1 : 
         return 6
    case segmentView2 : 
         return 4
    case segmentView3 :
         return 3
    default :
         return 0
    }
}

Answer 3

您始终可以为每个分段控制数据源创建单独的类，而不是将所有分段控制数据源指向同一个视图控制器。它比通过代码使用switch / if / else语句更清晰。
