iOS Tab Bar icons keep getting larger

问题

I am having a problem with my icons in my tabBar.

Tapping the same tab bar button repeatedly will keep increasing the tab bar icon's size.
If I push a different one, it goes back to its original size.

Any ideas what I should fix?

回答1:

As per the project shared by the OP (see question comments), it seems the tab bar image insets seem to be messing things up.

Steps to resolve the issue:

1. Select the tab bar item of the problematic ViewControllers in IB
2. Go to Size Inspector section (on the right)
3. Ensure your image insets are balanced
   • If you give 5px inset to top then balance with a -5px inset to bottom
   • If you give 5px inset to left then balance with a -5px inset to right

^{I have no explanation for this, sorry... but if anyone does then kindly comment/post}

try This..

myDealNavigationController.tabBarItem.imageInsets = UIEdgeInsetsMake(5, 0, -5, 0);

I was also running with same issue and above accepted answer helped me.

Just to show case what steps to do:

While setting image to tab bar select image and balance image insets from all sides.

Need to keep few things in mind:

As shown in below image, balance from all four sides.

It will make UI proper.

Thanks
