view-controller | Separate business logic from UI logic | Form library

I'm working on an app that requires locking the orientation in each view controller. I read this article, but it did not work for me. In the project settings, I set the device orientation to Portrait, Landscape Left, and Landscape right.

I have two view controllers, VC1 and VC2, and I want to lock the VC1's orientation vertically only. I want to lock the VC2's orientation, on the other hand, horizontally only.

Then I added the following code in VC1.

Visual Studio 2019 here, Community Edition, latest update.

Whenever I try to create a project using the template "ASP.NET Core WEB App (Model View-Controller)" it creates nothing. It shows me "Solution [name] (0) project (see the image below)

What is the problem? I uninstalled and reinstalled Visual Studio to no avail. .NetCore web development platform workload and asp.net workload are both installed.

Here's some screenshots of the installer => https://imgur.com/a/0Cxk8Bv Here - it looks like it creates some files in the specified location, but nothing shows in solution explorer at all => https://imgur.com/a/15iRIrC

I'm migrating an ASP.NET MVC 5 web app to ASP.NET Core (with .NET 5). In the previous web app I used glyphicons, but in the new one it seems that there are no available.

I created a new ASP.NET Core Web App (Model-View-Controller) project with .NET 5. I didn't change anything about bootstrap, it is v4.3.1, and if I use this HTML code no icon is shown.

I tried this solution, adding a link to v3.4.0 stylesheet, but this changes the style of the current web page.

Is it possible to use glyphicons in ASP.NET Core project without changing web's main style?

I am using sqliteOpenHelper class for sqlite. I am learning a android book for concepts. Everything is same as in book code. But in my case app crash and showing error.Please help me for resolve this problem. In logcat Column content does not exist. When i run app on device then app crash and logcat showing this

The app keeps crashing whenever I tap the push notification when the app is closed. If it's in the background or open when I tap the push notification then it loads just fine.

I've tried the suggestions over here: Swift - How to open specific view controller when push notification received?

Below are the relevant functions in the app delegate. Any print functions to determine where exactly the crash is caused is not being registered so I cannot debug properly. The only message I see is:

Message from debugger: Terminated due to signal 9

I feel like Model-View-Controller @ docs.nestjs.com doesn't cover this use case - there is "Dynamic template rendering" section + Fastify but both combined together don't seem to work well.

I've tried the following snippet:

I am developing a web app using the Net Core MVC structure. I have a page that is many search criteria and I want to send parameters over URL with getting request. I am using many select components on my view and it can be selected multiple values. I am sending one or multiple values over URL with the request. There is a paging system in my view and after making get request with filter values not retrieving or set values to select components. I am also using Select2 components. Briefly, paging creates a problem retrieving or sending values between view-controller.

I am updating an old iPad app, but I'm unable to stop iOS from rotating a controller that should only be viewed in portrait mode. The app has a UISplitViewController, but at one point I need to present another controller fullscreen in portrait mode regardless of whether the iPad was in portrait or landscape before.

I have two issues:

• If the UI was in landscape mode, the portrait view controller also appears in landscape
• The rotation is no longer blocked, so the user can rotate the device even if the controller was displayed in the correct orientation

The documentation says that all rotation-related methods were deprecated in iOS 8, and instead iOS will call viewWillTransitionToSize on the window's root viewcontroller. I am therefore calling [window setRootViewController] to setup my portrait-only controller, and indeed iOS calls viewWillTransitionToSize on my controller. However, at that point it's already too late! I need to stop the transition before it begins.

After spending many hours googling and trying variations, I am no closer to a solution – there is so much old stuff on the 'net (and here on Stack Overflow) that it's really hard to find current information.

I have tried setting modalPresentationStyle = UIModalPresentationFullScreen both in viewDidLoad, viewWillAppear and viewDidAppear, and then overriding preferredInterfaceOrientationForPresentation. My override is never called.

I still have the old methods supportedInterfaceOrientations, shouldAutorotate and shouldAutorotateToInterfaceOrientation, but none of them is ever called.

I tried implementing application:supportedInterfaceOrientationsForWindow in my app delegate, but the method is never called. (from the answers to this question)

What's the correct way of doing this on iOS 14? Should I use a modal full-screen presentation? Or use the trait environment with UITraitCollection somehow?

I'm presenting a simple view controller. To follow MVC, I moved my programmatic view code into a separate UIView subclass. I followed the advice here of how to set up the custom view.

This works ok in iPhone. But, on iPad, the view controller is automatically presented with the new post-iOS 13 default modal style .pageSheet, which causes one of my buttons to be too wide. I looked into the view debugger and it's because the width constraint is set to self.bounds.width * 0.7, and self.bounds returns the full width of the iPad (1024 points) at the time the constraint is set, not the actual final view (which is only 704 points wide).

Three questions:

1. In general, am I setting up the custom view + view controller correctly? Or is there a best practice I'm not following?

2. How do I force an update to the constraints so that the view recognizes it's being presented in a .pageSheet modal mode on iPad, and automatically update the width of self.bounds? I tried self.view.setNeedsLayout() and self.view.layoutIfNeeded() but it didn't do anything.

3. Why is it that the Snooze button is laid out correctly on iPad, but not the Turn Off Alarm button... the Snooze button relies on constraints pinned to self.leadingAnchor and self.trailingAnchor. Why do those constraints correctly recognize the modal view they're being presented in, but self.bounds.width doesn't?
