删除导航栏中的后退按钮文本和中心标题

Question

I've removed the text for UIBarButton in AppDelegate:

[[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -1000.f) forBarMetrics:UIBarMetricsDefault];

Which works like a charm:

As you can see, this doesn't align the navigation title at horizontal center. What is the best solution to accomplish this globally for all views.

PS: I am using Storyboard.

You can create your own custom titleView with a UILabel as follows:

UIView *titleView = [[UIView alloc]initWithFrame:CGRectMake(0,0,100,50)];
UILabel *titleLabel = [[UILabel alloc]initWithFrame:CGRectMake(0,0,100,50)];

titleLabel.textAlignment = NSTextAlignmentCenter;
titleLabel.text = @"PAKKELISTE";
[titleView addSubview:titleLabel];

self.navigationItem.titleView = titleView;

The details of the frames, text, alignment, etc. are just an example. The main idea though is that you set a custom UIView as the navigationItem's titleView.

It could also be an issue with your back button offset. Try this approach instead for removing the "back" text (I haven't tried this before, but I'm curious if it will work).

self.navigationController.navigationBar.topItem.title = @"";
