ios - Swift - UITableView didSelectRowAtIndexPath & didDeselectRowAtIndexPath Add & Remove indexPath IDs -

-

यह कोड है: 

  समारोह tableView (tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath ) {जाने SelectedItem = items.objectAtIndex (indexPath.row) स्ट्रिंग के रूप में जाने Itemid = selectedItem.componentsSeparatedByString ( "$% ^") // Itemid [1] - मद आइडी} समारोह tableView (tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {जाने SelectedItem = items.objectAtIndex (indexPath.row) स्ट्रिंग के रूप में जाने Itemid = selectedItem.componentsSeparatedByString ( "$% ^") // Itemid [1] - मद आइडी}

कैसे करें आइटम आईडी "अर्रे या स्ट्रिंग में या कुछ और ..." जोड़ें? जब आप 0,1,4,5 पंक्तियों का चयन करते हैं, उदाहरण के लिए आपके पास अलग-अलग आइटम आईडी हैं "ऐरे या स्ट्रिंग में" और फिर जब मैं उन्हें अचयनित करना चाहते हैं, तो IndexPath.row से सटीक आइटम आईडी को कैसे अचयनित करना है जो अचयनित है और ढूंढता है यह "सरणी या स्ट्रिंग में या कुछ और ..." और इसे हटा दिया? मेरे टूटी हुई अंग्रेजी के लिए क्षमा करें यदि आपके पास कोई प्रश्न पूछने पर पूछते हैं और मैं समझाऊंगा कि क्या मैं

आप

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

-
We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
