Question

I’m doing a custom nav in ios for the first time. I have six buttons laid out in a row. When I tap the button, I want the image to change. However, the button is not togglable. The only way a button can be unselected is if another button is touched. Only one button can be active at any given time.

My idea:

• use UIButtons
• change UIButton image on touch
• keep track of the active button inside the navigation class
• when an inactive button is touched, make the currently active button inactive and turn the touched button to active

I want the end product to work like a custom TabBarController, but without switching layouts. I just want to edit the content in the current ViewController.

Is there a better way to do this?

Answer 1

I setup the UIButtons in the Interface Builder like so:

• Default with unselected background image
• Disabled with selected background image

On touch, a button is self.enabled = NO which makes the UIButtons look change. However, the button goes dim, so I also implemented self. adjustsImageWhenDisabled = NO.

This way a button can’t be re-selected once it’s “active”.
