iOS拖放

Question

I would like to make an easy app - game with a letters.

I am searching for an example, how to drag an image and drop it to a position which belongs only to this image.

There will be for example a picture of apple on background and 5 UIImageView with letters A, P, P, L, E. You take a letter A and bring it to the right UIImageView (which belongs only to the letter A - in another you can´t). Than letter L and so on ... until there is written apple.

I can drag and drop each letter everywhere on a screen (there exists a lot of tutorials :)).

But I don´t know, how to drop for example letter A - to the right UIImageView who was made only for a letter A.

Do you know about some tutorial or source code or example?

Thank you very much...

There's a simple open-source framework for iOS called "iOS-DragAndDrop" that does exactly what you need. You can define any UIView as a draggable view, and you can define specific views (including invisible ones) that that draggable view can be dropped into.

Check it out: iOS-DragAndDrop on Github

There's documentation at that link as well.
