导航栏中重叠的标题

Question

I have ViewController with a button that animated pushes second viewController to navigation stack.

On that second controller I have a button with action that animated pop itself from navigation stack.

If i repeatedly and quickly press them one by one, titles in the navigation bar will overlap each other.

Here is a screenshot of overlapped titles:

How can I rid of this problem?

Edit:

I have same issue, it generates randomly. I have UIViewController with UITableView , by tapping UITableViewCell it navigates to UITableViewController.

Sometimes UITableViewController 's title is overlapping with UIViewController 's title when I click on back button.

NOTE: There is no custom title or custom navigation items, all controls are default controls.

Navigation title was set using below code:

self.title = @"Mail (28)";

I'm using

Xcode Version 8.0 (8A218a)

Simulator iPhone 7 - iOS10 (14A345)

Answer 1

Inside your 1st ViewController , assign Blank String upon transition (line before you triggered the 2nd ViewController ):

self.title = ""

And onViewWillAppear() of the 1st ViewController , reassign the

self.title = "previousvalue"
