UINavigationController Back button title always sh

Question

I am developing an IOS application. I am using navigation controller. If I push to next page then back button title not shown previous page title in IOS 7. Back button title always "Back" in IOS 7. I set all pages titles in viewWillAppear, viewDidload like below. But it is not working.

self.navigationItem.title=@"Previous Page Title";
self.title  = @"Previous Page Title";

What can I set back button title with previous page title in IOS 7

Thanx

Answer 1

If the title is large, back button shows back only.Try with short titles,like

self.title = @"Test";

if you want Long title , go for custom back button.

If you want to force to always have the back button, but still let the system create it for you (will handle "Back" localization, abbreviate the button to a single "<" if the current title is really long, etc), then just use an absurdly long back button title:

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"                                                                                               really long never shown title"
                                                                         style:UIBarButtonItemStylePlain                                                                               
                                                                        target:nil
                                                                        action:nil];

Try this code:

[[UIBarButtonItem alloc] initWithTitle:@"Your Title Here"
                         style:UIBarButtonItemStylePlain                                                                               
                         target:nil action:nil];

Or you can set an image for button like this:

UIBarButtonItem *barBtn = [[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"arrow.png"] style:UIBarButtonItemStylePlain target:self action:@selector(back:)];

self.navigationItem.leftBarButtonItem = barBtn;

And @selector method:

-(void)back:(id)sender{
  [self.navigationController popViewControllerAnimated:YES];
}

In iOS 7 the back button length is constrained (I think to 11 chars). You can set a custom "back button title" like this, for example in viewDidAppear in the view controller with the long title (not the current view controller!):

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back Title"
                                                                         style:UIBarButtonItemStylePlain                                                                               
                                                                        target:nil
                                                                        action:nil];
