How to make leftBarButtonItem looking like backBarButtonItem? - ios

Question

The default solvings are not appropriate:
to change the previous ViewController title - I need to make my own function controlling the button touches up
to make a leftBarButtonItem and hide backBarButtonItem - leftBarButtonItem doesn't look like a default backBarButtonItem.

Answer 1

Here's an example to create a custom leftBarButtonItem:
UIImage *buttonImage = [UIImage imageNamed:#"backbutton.png"];
UIButton *aButton = [UIbutton buttonWithType:UIButtonTypeCustom];
[aButton setImage:buttonImage forState:UIControlStateNormal];
aButton.frame = CGRectMake(0.0,0.0,buttonImage.size.width,buttonImage.size.height);
[aButton addTarget:self action:#selector(aSelector) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:aButton];
self.navigationItem.leftButtonItem = backButton;
Hope it helps...
Edit:
Try this...
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"yourimage.jpg"] style:UIBarButtonItemStyleBordered target:self action:#selector(aSelector)];
self.navigationItem.leftBarButtonItem = backButton;
I don't remember what type of button is the backbutton, try to change the default style to other. Good luck!

Answer 2

Just create a custom barbuttonitem and customize it with a picture similar to the back button item.
You can get its text from the view controllers in the navigation stack.
Then handle the taps to implement the desired effect

Answer 3

You can assign your custom views as the bar buttons to your navigation controller, like this:
UIBarButtonItem *customItem = [[UIBarButtonItem alloc] initWithCustomView:yourCustomizedControl];
[yourCustomizedControl release];
self.navigationItem.leftBarButtonItem = customItem;
[customItem release];
Check this Apple documentation for a more detailed explanation, if you want.

Answer 4

Here is a hack to add a back-like button:
UINavigationItem* backNavigationItem = [[UINavigationItem alloc] initWithTitle:#"Back"];
[_navigationBar pushNavigationItem:backNavigationItem animated:NO];
[backNavigationItem release];
You can add more items (such like title, right button) this way:
UINavigationItem *navigationItem = [[UINavigationItem alloc] initWithTitle:#"Title"];
navigationItem.rightBarButtonItem = // Some UIBarButtonItem
[_navigationBar pushNavigationItem:navigationItem animated:NO];
[navigationItem release];
