I had a customcell for my tableView.Recently I have changed some controls in the cells.I am facing a problem.The new controls are not showing when I am running my application.
Even I removed all the labels, uibuttons from the cellView.But nothing is working.It's something like it's stored the controls in the memory.How can I get rid of this?
Try to clean the project and build again.

I'm new to react and fluentui development and am having trouble getting the Grouped List examples to work https://developer.microsoft.com/en-us/fluentui#/controls/web/groupedlist
Nothing renders until I remove the SelectionZone element. But then I can't select items.
I'm seeing the following error in the console (which doesn't mean much to me):
useFocusRects.js:67 Uncaught TypeError: Cannot read properties of undefined (reading 'current')
How should I troubleshoot this?
-- Edit --
I created a CodePen
https://codepen.io/matthewfitzmaurice/pen/NWMbXNP . But the CodePen works fine...
I've also noticed that a form that I created containing TextField, DatePicker and ComboBox has stopped working. The error occurs when I use a ComboBox. It's fine if I only use TextFields and DatePickers.
My ComboBoxes were working and now are not. This seems to indicate that I've installed something and broken some of the FluentUI controls.
In case anyone else runs into the same issue, my problem was version related.
Updating my npm packages fixed the issue.
npm outdated
npm update
Further to my earlier question
Migrating iOS Hybrid App from UIWebView to WKWebview
I have made good progress and only have a few loose ends to tidy up. The overall performance improvement over UIWebView is outstanding.
In UIWebView it was possible to set the focus on a text field programatically using
webView.keyboardDisplayRequiresUserAction = NO ;
However this is not available in WKWebView and ever since 2016 programmers have been developing an updating work arounds (swizzles) to overcome this.
I have tried implementing the latest of these I could find on Stack Overflow, which I found at https://stackoverflow.com/a/55344531/5948260
However as I am very inexperienced at coding in XCode please could someone tell me exactly how I add the above solution to my project. I have tried in vain to find examples of how exactly to do this i
on GitHub or elsewhere but to no avail.
So far I have tried copying the code provided in the above answer into a .m file and adding it to my project, but I got 20 or so errors, I then added an import statement for Foundation and most of these went away but XCode complained that it did not know what class WebViewInjection is. Also must there be a corresponding header file?. Must there be a corresponding interface statement? How does the method defined in the answer get invoked?
As I could not answer any of these, I also tried adding the method into my ViewController class. Whilst this was accepted with no errors, it had no effect on my app, ie. the keyboard did not come up automatically.
I would also want the webview to resize to appear above the keyboard and not to scroll to where the text field is as this seems a very messy solution to me.
All help very gratefully received.
I have now managed to get the keyboard displayed by adding
[self allowDisplayingKeyboardWithoutUserAction];
to viewDidLoad
I kept the allowDisplayingKeyboardWithoutUserAction method declaration inside my ViewController but changed the + infront of the method declaration to a - and this seems to have worked.
I still do not know how to resize the webview when the keyboard is displayed.
I'm working on an app that'll have a range of images and the collectionview is not showing up at all. I was following this article, which I translated to C#.
here is an example app I made to show a minimal example of what I'm trying to do.
When I run through the code, GetCell in the collection source isn't firing which I know is the problem, but I don't know why it's not firing and I'm simply at a lost on what I'm missing.
I test it again today and I can make sure that the problem is caused by the MosaicCollectionLayout.
What I did today is that I removed your collectionView and add a new collectionView, then I add Constrains to it with a fixed height and width(to make sure it appears even if there is no data), then I change the layout to FlowLayout, it works, here is the screenshot:
After that, I changed the layout back to MosaicCollectionLayout, I get an exception in the line _cachedAttributes.Reverse(lastIndex.Row, firstMatchIndex.Value); inside the method LayoutAttributesForElementsInRect.
I checked the article and did not find a solution yet. Maybe there is some mistakes in the codes translated from swift to C#. So the problem is not related to the xib, please check the code in the method LayoutAttributesForElementsInRect.You can also try add Constrains to your collectionView. Hope these information helps you.
I am using SetWindowText() of CMDIChildWnd from CScrollView for setting the title from , when I open a document. But title did not get updated, untill I click on the image or when I minimize the application.
I have tried with calling Invalidate(), UpdateWindow() but none of these are working, but I anyhow need to update the title.
Can anyone please let me know how can I do this.
Thanks!
Call the documents SetTitle() method with the title you want. SetTitle() will call CDocument::UpdateFrameCounts(), UpdateFrameCounts() will call the CMDIChildWnd::OnUpdateFrameTitle(TRUE) which will update your frame.
I would think SetWindowText() would work, but it might be that OnUpdateFrameTitle() is getting called afterwards because of UI updating or something, and that OnUpdateFrameTitle() is setting the title back to what it was. Try a breakpoint in CMDIWHildWnd::OnUpdateFrameTItle() or in the CMDIFrameWnd version as well.
I am new to iPhone. I have Develop one aplication that is of ViewBased Application.
Everything is right but while i run the application, instead of showing list of content it shows the white screen. After doing studies come to know that it may be for the XIB file references. As my code is right at all. So will u tell me while it appear like it ?
Thanks in advance.
check your .xib file and see whether you have link it to datasource and delegate or not.
Check your xib and properly check inteface builder that a datasource and delegate is set or not. for showing a view you have to set datasource and delegate..and also you have to check in appdelegate file that a object of your view controller have been made or not... i.e. you have to allocate memory of your view controller in app delegate file..
