Split this into three tasks:
Containing the data you want into an appropriate UIView-based class/subclass
Handling the relevant touch events to initiate and end the drag and drop
Animating the move between your source and destination
You can implement these one at a time in order to develop precisely the drag and drop functionality you need.
You shouldn't need to convert your view to an image, as UIView subclasses can be animated by Core Animation. This SO post has more info on handling touch events.
Good luck!

I have created a custom accessory view to supplement the standard Apple alpha iOS keyboard.
The purpose is to add a line of numeric keys to prevent flipping back and forth between keyboard views. At first, I created a toolbar and loaded it with a set of 0 - 9 titled buttonItems and it functioned quite well. However, it looked terrible, not at all like the alpha keys despite adding a rounded rect background image to each key because the system apparently prevents customizing font size and button spacing inside the stack view of the toolbar. Therefore, I created a UIView xib and loaded it with a stackView full of customized numerical buttons. When I add the UIView as the accessory view it looks pretty darn close to the rest of the Apple Alpha keyboard. The issue now is that the touch-up events go to the UIView class of the accessory view. Is there a clever, efficient way to have the button presses in the accessory emulate the std keyboard feeding into TextField: shouldChangeCharactersIn? I could package the button presses into a local notification event to get it into the class holding the textField but that seems terribly inelegant! Any suggestions would be greatly appreciated. Stay Safe!
Not the best answer, but I did implement notification on key button press with an observer in the main view class. The observer does a TextField.insertText which is suboptimal since I will need to refactor the several hundred lines of code that performs real-time language translation in the shouldChangeCharacters methods. Ah well.

I am making app like sudoku (9*9 boxes) but it has only binary choices (on/off) and using button gave me horrible results. Can anyone give me demo version of 9*9 (or 3*3) box where depending upon the tap location, that specific box gets toggled (on/off)
You could create a custom subclass of UIView that had an attached tap gesture recognizer and interpreted the tap location to figure out which cell is being tapped, but it would be a lot of work.
It would be better to have custom view that contains a grid of buttons and set up the button actions to do what you want.
You said "...using button gave me horrible results." Can you elaborate? That should be a good way to go, so any "horrible results" are likely the result of something you did wrong, rather than that being the wrong way to go.
So i'm making an application for tracking livestock. I have made a table view for the animals to go in. I have a navigation controller at the top with a button in side of it.Here is what i have so far.
I would like to have a floating table view come up when the button is pressed similar to the 3D touch menu.
Like these.
My question is how would i go about doing this. Sorry if this is a commonly done thing im pretty new to swift and xcode
If you just wanna to implement，you could search the key words as 'pop over', 'kxmenu' or 'menu' on GitHub/CocoaControls. such like this: https://github.com/zpz1237/NirKxMenu https://github.com/liufengting/FTPopOverMenu
Also, you should make it yourself. When the button is pressed, first you should create a custom window and make it key window. Secondly, add a tableView or a view contains tableView to the custom window. then, use block or delegate to deal with data communication and respond user interaction. After that, design animation you need. At last, remove subviews from custom window and make the original window key window.
I want to get the keyboard size without using NSNotification. When I press the plus button, it can replace the keyboard with a custom UIView like this:
Then the plus button is pressed and the view loaded:
How can I achieve this?
I already made same rookie mistake like you want to do here. The problem is you will write a lot only to realize you do not want to avoid standard flow provided you by iOS team. For example you will definitely have a bad time dealing with issue like this one (there is additional bar which is part of standard keyboard for Chinese locale):
I solved this by using other people's work from DAKeyboardControl project. You do not need to attach observer (or if you use DAKeyboardControl - block) directly to your bar with buttons, but to your controller and check what user is trying to do and animate this bar accordingly. In the sources you can see how to get keyboard's animation duration and timing function. It may sound more complicated than it indeed is, just give it a try.
I want to create a custom Field to show news. I have 20 news headlines, but only one will be visible. The field will have a timer that will change the new headline every 3 seconds. Creating a timer task is fine. But the real problem is, the animation while the headline change. I want to create a flip animation. How to do flip animation on the field?
I have used screen transition. But that does animation for the entire screen. But my requirement is to flip a screen widget.
Looking to develop for 5.x and above.
Unfortunately there is no transition for fields, so you could use third party code or write it yourself. You could find more insights here:
