navigationBar上面添加自定义leftBarbuttonItem和rightBarbuttonItem,自定义titleView的时候不能居中，根据leftBarbuttonItem的位置计算titleView的宽度和x还是位置还是不能居中，求大神解答
走同样的路，发现不同的人生
By default, set leftBarbuttonItem and rightBarbuttonItem, then set titleView, titleView is centered. If possible, you can send a screenshot of the code to help you find the problem.
估计是你计算错了吧
I encountered the same problem. After searching everywhere, there was no answer. Finally, I tried it out with code.
How to say:I added the following code after setting the custom titleView after ViewDidLoad:[self.navigationItem.titleView layoutIfNeeded];
