iOS back button turns totally black

During the test process of my app, only 2 people said their back button turns totally black, showed in the following image: enter image description here

I've searched the Internet but failed to find a similar problem. Can someone tell me why does this happen?

Edit: Well actually my code that has sth to deal with the tint color is only this single one: [[UINavigationBar appearance] setBarTintColor:[UIColor BBTAppGlobalBlue]]; In AppDelegate.m In which BBTAppGlobalBlue is a custom color, which should be a kind of blue.

Solution

  • I am not sure for this ans.Try once changing button shape.
