问题描述

我有一个带有 4 个段的 UISegmentedControl.当它被选中时，它应该弹出视图.当弹出窗口关闭并尝试单击相同的段索引时，它应该再次显示弹出窗口.使用以下在弹出关闭后点击同一段索引没有任何动作.

当按下段控件时写下面的代码.

when the segment controll is pressed write below code.

@IBAction func segHeaderPressed(sender: UISegmentedControl) {

@IBAction func segHeaderPressed(sender: UISegmentedControl) {

如果 segHeader.selectedSegmentIndex == 0{

if segHeader.selectedSegmentIndex == 0{

让 sortedViews = sender.subviews.sort( { $0.frame.origin.x <$1.frame.origin.x } )

let sortedViews = sender.subviews.sort( { $0.frame.origin.x < $1.frame.origin.x } )

        for (index, view) in sortedViews.enumerate() {
            if index == sender.selectedSegmentIndex {
                view.backgroundColor = iOSBlueColor // UIColor.blueColor()
            } else {
                view.backgroundColor = UIColor.clearColor()
            }
        }

selectedInd = -1

selectedInd = -1

//你的代码...}else if(segHeader.selectedSegmentIndex == 1){

//your code ... }else if(segHeader.selectedSegmentIndex == 1){

        let sortedViews = sender.subviews.sort( { $0.frame.origin.x < $1.frame.origin.x } )

        for (index, view) in sortedViews.enumerate() {
            if index == sender.selectedSegmentIndex {
                view.backgroundColor = iOSBlueColor //UIColor.blueColor()
            } else {
                view.backgroundColor = UIColor.clearColor()
            }
        }

//你的代码...}else if(segHeader.selectedSegmentIndex == 2){

// your code ... }else if(segHeader.selectedSegmentIndex == 2){

让 sortedViews = sender.subviews.sort( { $0.frame.origin.x <$1.frame.origin.x } )

let sortedViews = sender.subviews.sort( { $0.frame.origin.x < $1.frame.origin.x } )

        for (index, view) in sortedViews.enumerate() {
            if index == sender.selectedSegmentIndex {
                view.backgroundColor = iOSBlueColor //UIColor.blueColor()
            } else {
                view.backgroundColor = UIColor.clearColor()
            }
        }

}else if(segHeader.selectedSegmentIndex == 3){

}else if(segHeader.selectedSegmentIndex == 3){

让 sortedViews = sender.subviews.sort( { $0.frame.origin.x <$1.frame.origin.x } )

let sortedViews = sender.subviews.sort( { $0.frame.origin.x < $1.frame.origin.x } )

        for (index, view) in sortedViews.enumerate() {
            if index == sender.selectedSegmentIndex {
                view.backgroundColor = iOSBlueColor //UIColor.blueColor()
            } else {
                view.backgroundColor = UIColor.clearColor()
            }
        }

}}

基本上分段控制功能是一旦被选中，如果你再次点击它不会响应.所以我只是改变所选片段的背景颜色.希望它可以帮助某人.

basically segmented controll functionality is once it is selected if you tap again same it will not respond. so am just changing the background colors of selected segment. hope it helps someone.
