Question

I have an app with a navcontroller created in the appdel. Each vc pushed in has a block of code in the viewdidload that sets up the toolbar. The toolbar is always the same. Is there a way for me to just create this code once – and not put it in every vc?

    [self.navigationItem setHidesBackButton:YES];

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Home" style:UIBarButtonItemStyleBordered target:self action:@selector(backClicked)];

UIBarButtonItem *flexibleSpaceLeft = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];

UIBarButtonItem *storyBtnItem = [[UIBarButtonItem alloc]initWithTitle:@"Sto" style:UIBarButtonItemStyleBordered target:self action:@selector(toolbarControl:)];
storyBtnItem.tag = 1;
UIBarButtonItem *renderBtnItem = [[UIBarButtonItem alloc]initWithTitle:@"Ren" style:UIBarButtonItemStyleBordered target:self action:@selector(toolbarControl:)];
renderBtnItem.tag = 2;
UIBarButtonItem *amenBtnItem = [[UIBarButtonItem alloc]initWithTitle:@"Ame" style:UIBarButtonItemStyleBordered target:self action:@selector(toolbarControl:)];
amenBtnItem.tag = 3;
UIBarButtonItem *availBtnItem = [[UIBarButtonItem alloc]initWithTitle:@"Availability" style:UIBarButtonItemStyleBordered target:self action:@selector(toolbarControl:)];
availBtnItem.tag = 4;
UIBarButtonItem *eopBtnItem = [[UIBarButtonItem alloc]initWithTitle:@"Eq" style:UIBarButtonItemStyleBordered target:self action:@selector(toolbarControl:)];
eopBtnItem.tag = 5;
UIBarButtonItem *stkBtnItem = [[UIBarButtonItem alloc]initWithTitle:@"St" style:UIBarButtonItemStyleBordered target:self action:@selector(toolbarControl:)];
stkBtnItem.tag = 6;
UIBarButtonItem *movBtnItem = [[UIBarButtonItem alloc]initWithTitle:@"Fi" style:UIBarButtonItemStyleBordered target:self action:@selector(toolbarControl:)];
movBtnItem.tag = 7;
NSArray *items = [NSArray arrayWithObjects:flexibleSpaceLeft, stoBtnItem, reBtnItem, ameBtnItem, avaBtnItem,  eBtnItem, stBtnItem, mvBtnItem, nil];  
[self setToolbarItems:items];
[self.navigationController.toolbar setTintColor:[UIColor colorWithRed:79.0/255.0 green:145.0/255.0 blue:205.0/255.0 alpha:1.0]];

Answer 1

Just do vc.toolbarItems = self.toolbarItems (where vc is the view controller to be pushed) in the method where you are pushing the next view controller.

eg:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIViewController *vc = [UIViewController new];
    vc.toolbarItems = self.toolbarItems
    [self.navigationController pushViewController:vc animated:YES];
    [vc release]; // if not using ARC
}

Also, you don’t need to do this in the -viewDidLoad method, setting the navigation items and toolbar items does not require the view to be loaded and can thus be done in your init or awakeFromNib method. If you do it in -viewDidLoad you are potentially setting the items multiple times.
