Drag and drop Xamarin Forms (iOS only) objects - xamarin

Dello, I have a project in xamarin forms.
As you can see in the picture, I have drug images and buttons that contain the ingredients in the drugs.
I want to drag and drop buttons to the drug images so that I can tell the user that they are correct or wrong. Does anyone have an idea ?

Ionic 4 popover and/or actionsheet on PWA?

I'm building an Ionic 4 PWA and I am looking for a "simple" solution to the following:
For each item in a list e.g. a newsfeed or comments list: I want a "more" icon (the dotdotdot icon) to show a list of options the logged in user has available e.g. if they own the comment or newsfeed item they will have extra options like "edit" and "delete" etc.
Now I can use an ActionSheet to show these options and dynamically add the correct options into the sheet - all well and good. But this only looks good on a mobile device. If the user is on a desktop then an action sheet looks out of place. So, a Popover would look better but only on the desktop view.
Is it possible to dynamically create a popover in code without having to create a component for it as the items in the popover list will vary depending on what type of object it is e.g. newsfeed, comment etc and their access rights to that object e.g. edit/delete etc.
Not sure if I have explained this very well but looking for a slick, simple UI Ionic 4 way of displaying "options" to the user when then click/tap on the more icon depending on device.
I did go down the route of having ActionSheet for mobile users and Material Design Mat-Menu for the desktop but it just seems over complicated.
Any advice would help.
Thanks,
Rowie
How about a popover with a custom css class that is using a screen media query?

Xcode 4: Iphone - Adding a table view to an existing project

I'm new to programming IOS and I'm creating a small App for our College. This app consists of a main view that has a couple of buttons to open different things (Map, Welcome message from the Dean, Intro video, etc...). One of these buttons will open a table view that will show our 5 campuses. When they select a campus it will open a UIWebView that shows the information about that campus.
My problem is that I was able to add a nib to my project and place a tableview object in that nib. It displays, but I,m not able to get the navigation bar or navigation button to show.
Would you have any site or suggestions?
Thanks
Ren
You should try using an Navigation Controller. When you connect the other views to it, it will automatically add the bar and the button.
Good luck!

In WP7, how to Add Tile form My ListBox Item?

I try to add Tile form ListBox Item of my app:
Like Friend hub, Game hub...
Let User tap one item, show "pin to start",
then more Tiles on start page with different picture or word.
Is it possible ?
If you mean adding to the phone home screen, there can only be one tile for your app. This is added via the application list to the right of the home screen via tap and hold on your app icon.
Do you mean that you want to add more than one tile for your application to the home page in the same way that you can with map locations from the Map app and with notes from the OneNote application? If so, then you can't do this with the current development framework, though I personally hope that it will be available in the future.
