ToDo-App Checkmark

Each todo app has a empty box on the left handside, when you touch the box, it changes to a checked box. When you tap it again, the checkmark disappears. I think everybody knows what I mean.

As you see it here (right):

How would I realize something like that ? Is it a UIButton ? I'm working with Core Data, how would I save the state ? With a boolean varibale ?

I tried to solve my problem now for days, but wasn't able to get it work.

Would be soo nice, when you could help me. Thx a lot ! Sebastian

Solution

  • You can use a UIButton with different images for the default and selected states. Then, if you set the selected property to YES, the selected image will show instead.

    To store it, I'd say that a BOOL should be enough.
