I am trying to use the PopoverController in Ionic 6 with Vue 3 (Composition API). Now, as I can not just add an #custom-event to my popover, I do not know, how to respond to custom events from my popover inside the parent component. Of course, you could pass callbacks as props, but that's pretty much an anti-pattern in vue.
Any ideas on how to pass custom events from the popover created by the popover controller to the parent?

I have a TabBarIOS which contains five navigators. I need to track each view on screen for google analytics, but ReactNative doesn't provide a lifecycle for that.
I'v tried to track in the componentDidMount of those views, but it will be only called once in its lifecycle for each view. Switching between tabs will not trigger componentDidMount again.
Furthermore, when I push()/pop() a view into/from a navigator, I need a callback to find which component will be shown.
Is there any callback method or delegate method which would be called when a component is going to show (like -viewDidAppear: in iOS)?
TabBarIOS.Item has a property named onPress() that gets called when the item is pressed. You can use this callback to update analytics.
I had a problem with Aurelia's binding system. I want so.e clarification on how view and viewmodels interact.
Lets say I have a div. This div has child divs that get generated by Aurelia's "repeat.for". I then have a function that does something to the parent div and its children. Where or when do I call this function. From experience, I cant call the function in the attached() hook because Aurelia's binding system is asynchronous so not all child divs may be ready by the time I call my function
I have something like a modal view controller that I need to display above my other view controllers. I’m not using the regular modal controller feature (presentViewController: and friends), since I need better control over the process. Instead I am using the view controller containment feature (the addChildViewController: method group).
The containment feature makes the code fairly straightforward. When I need to present the “modal” view controller, I add it as a child to the view controller hierarchy and everything works as expected. One small catch is that the regular view controllers are wrapped in a navigation controller. Therefore I have to add the modal controller as a child of the navigation controller, otherwise it would be covered by the navigation bar and toolbar.
Now the problem is that calling addChildViewController: on a navigation controller also sets the new controller as the topViewController, as if the controller was pushed using the regular pushViewController: method. This means that while the modal controller is displayed, the regular controller underneath it does not receive the appearance and rotation callbacks.
This feels like a bug, or am I missing something?
I had the same problem. I resolved this by writing my own custom view controller, containing a UINavigationController (added via addChildViewController:) and then exposing the UINavigationController as a readonly property. Then you can add your modal view controller as a child of your new custom view controller instead of as a child of the UINavigationController
I missed this sentence in the documentation for addChildViewController:
This method is only intended to be called by an implementation of a
custom container view controller.
So I guess it’s my fault and this scenario is simply not supported. Which sucks, because it’s very convenient to design whatever modal things as regular view controllers and connect them to the hierarchy like proper first-class citizens. I would probably have to rewrite the navigation controller on my own to have built-in support for this.
I'm new to yii development.
In my system I'm trying to create a submenu system. The submenu will be shown based on the
controller. The submenu will be separate views, that I'll load in main layout.
I want to separate the logic of loading the submenu view from the main layout. But, I'm not sure where to write it.
Does Yii has view helpers like in RoR. Or, should I write it as a component?
Please give suggestions.
Thanks.
I'd just create a component for this, and instantiate that with the relevant menu options from the controllers. If present in all controllers, implement support in a BaseController and just set up an array of items in the child controllers.
Your default generated Yii application has a parent Controller in protected/components/Controller.php. If you need to access additional parameters in layout, add public properties to Controller, set them in your child controller, and use them in your view/layout files.
In your case, add a function to this parent Controller that returns a rendered submenu (with a renderPartial call for example) and call this function from your layout.
I'm looking for a solution to create a sort of template in Objective C. I'll try to explain my problem.
I would create a sort of main view which has 1 side bar that remain always visible. This side bar have controls. The main view is responsible to load a Navigation Controller (UINavigationController seems to be ok) that manages other views. When switching a view to another, the sidebar always remain visible under the Navigation Controller and its views.
Through the controls of the sidebar, it's possible to send event to a specific view loaded by the Navigation Controller.
Any idea to create a similar template?
Thank you. Best regards.
It sounds like you want a splitview which is implemented by UISplitViewController.
