ios 11 - UIButton inside UIBarButtonItem causes an autolayout error

Question

I\'ve a known issue with adding a UIButton into UIBarButtonItem. I\'ve tried to add auto layout constraints as suggested in stackoveflow but I\'m getting an error described

Answer 1

Use this simple way to create button with auto layout. Create button will have with flexible width according to size of the UIView. There is no need to add extra constraints.

UIButton *sortButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [sortButton setFrame:CGRectMake(10, 0, self.view.frame.size.width - 10, 30)];
