How to change a UIBarButtonItem in a UINavigationBar

Question

I\'m trying to set up a list of items that can be edited. I have a main view, with a UINavigationBar at the top and a UITableView directly under it. I\'d like to have my \"edit\

Answer 1

I create one button that can change from Edit to Done. It's a tip from More iPhone Development book.

- (void)viewDidLoad {
    [super viewDidLoad];

    UIBarButtonItem *editButton = self.editButtonItem;  
    [editButton setTarget:self]; 
    [editButton setAction:@selector(toggleEdit)]; 
    self.navigationItem.leftBarButtonItem = editButton; 
}

And the method toggleEdit

- (IBAction)toggleEdit { 
    BOOL editing = !self.tableView.editing; 
    self.navigationItem.rightBarButtonItem.enabled = !editing; 
    if (editing) {
        self.navigationItem.leftBarButtonItem.title = NSLocalizedString(@"Done", @"Done");
        //Added in the edition for this button has the same color of the UIBarButtonSystemItemDone
        self.navigationItem.leftBarButtonItem.style = UIBarButtonItemStyleDone;
    } else {
        self.navigationItem.leftBarButtonItem.title = NSLocalizedString(@"Edit", @"Edit"); 
        //Added in the edition for this button has the same color of the UIBarButtonSystemItemDone
        self.navigationItem.leftBarButtonItem.style = UIBarButtonItemStylePlain;
    }
    [self.tableView setEditing:editing animated:YES]; 
} 

Then you don't need replace any of them.
