We code with Swift 2.2, and make 2 buttons on the top navigation bar :
one on the left called addFriend
, one on the right setting
. On the page of setting I've added a back button.
We test with devices whose system are lower than iOS 10, they work fine, but with iOS 10, after tapping on the right button (setting
) and then tap back button to go back to the view (which have left and right buttons ), images of the buttons (left and right) disappear, but they remain functional.
How can I make them appear ?
