UIBarButtonItem as a BackButton

Question

I have two view controllers. The first is the login page and the second is the user cabinet. When I sign in and go to second view I can see back button "FirstController" at the Navigation Bar. But I don't need of this button and I want to have rect button as a "Sign Out".

Question: how can I set rect button "Sign Out" as a back button?

Answer 1

Hide UINavigationbar's Hide button while requesting to load from login page & while loading "FirstController", initialize your UIBarButtonItem with custom view - UIButton (Sign Out button) and also set selector to respond as click on "Sign Out".

Sample Code:

To Hide back button:

self.navigationItem.hidesBackButton = TRUE;

To add "Sign Out" button:

-(void)setMySignOut
{
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button setImage:[UIImage imageNamed:@"btn_logout.png"] forState:UIControlStateNormal];
    [button setImage:[UIImage imageNamed:@"btn_logout_h.png"] forState:UIControlStateHighlighted];
    button.frame = CGRectMake(0, 0, 70, 30);
    [button addTarget:self action:@selector(btnLogoutClicked:) forControlEvents:UIControlEventTouchUpInside];
    self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc] initWithCustomView:button];
}

-(void)btnLogoutClicked:(UIButton *)sender
{
    // your logic goes here...
}
