I have been trying to subclass the UINavigationController class for modifying things like background

  • 0

I have been trying to subclass the UINavigationController class for modifying things like background image, navigation bar size, back button, tittle font and so on.
After a couple of hours and a lot of reading I have understand that I should not subclass the UINavigationController class…

I would like to have specific design and transfer that design to all screens that use my custom NavigationController…

SO far I haven’t fount any elegant solution for this, most of the solutions are based on configuring something for showing in the next screen only (next view).

How can I achieve this? Maybe using categories?
Thanks in advance.

    I am showing code for custom leftbarbutton of UINavigationcontroller. You can add this code in each view controller and for both button( right and left)

        leftButton = [UIButton buttonWithType:UIButtonTypeCustom];    
    [leftButton setImage:[UIImage imageNamed:@"Yourcutomeimage.png"] forState:UIControlStateNormal];    
    leftButton.frame = CGRectMake(0, 0, 30, 30);
    [leftButton addTarget:self action:@selector(youraction:) forControlEvents:UIControlEventTouchUpInside];  

    self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:leftButton]autorelease];

    //or

    self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:leftButton]autorelease];

    Hope, this will help you..
