Change NavigationBar Title (font and color) in different View Controllers

Question

I was trying to customize the look of the Navigation Bar Title in my app.

I had to build a Custom Navigation Controller (not just for this issue), so I thought to override the setTitle function like this

- (void)setTitle:(NSString *)title
{
    NSLog(@"SETTING TITLE %@", title);
   [super setTitle:title];
   UILabel *titleView = (UILabel *)self.navigationBar.topItem.titleView;
   NSLog(@"title view is %@", titleView);
    if (!titleView) {
        titleView = [[UILabel alloc] initWithFrame:CGRectZero];
        titleView.backgroundColor = [UIColor clearColor];
        titleView.font = [UIFont fontWithName:@"TradeGothicLTStd-Bold-Accent-Accent" size:20];
        titleView.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
        titleView.textColor = [UIColor whiteColor];
        self.navigationBar.topItem.titleView = titleView;
        [titleView release];
    }
    titleView.text = [title uppercaseString];
    [titleView sizeToFit];

    self.navigationBar.tintColor= [UIColor colorWithRed:130.0f/255.0f green:120.0f/255.0f blue:90.0f/255.0f alpha:1.0f];
}

Everything was working as expected. Now the issue is that inside a navigation controller I have a TableView. When clicking a cell, the app drills down to another TableView, which should have again the custom title.

this is the code for the didSelectRowAtIndexPath:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:indexPath];
    NSString *category_id = [[managedObject valueForKey:@"category_id"] stringValue];
    NSString *name = [[[managedObject valueForKey:@"name"] description] capitalizedString];
    CategoryViewController *category = [[CategoryViewController alloc] initWithNibName:@"CategoryViewController" bundle:nil];
    category.category_id = category_id;
    category.name = name;
    category.managedObjectContext = self.managedObjectContext;
    // ...
    // Pass the selected object to the new view controller.
    [self.navigationController pushViewController:category animated:YES];
    [category release];
}

....but when the selected view appears, it shows with the standard font.

EDIT I noticed that if in the second view I set the title in the viewDidAppear method, it happens something different. if I write

- (void)viewDidAppear:(BOOL)animated
{
self.navigationController.title = name;
[super viewDidAppear:animated];
}

...the title in the navigation bar has the right (custom) font, but the title is like appearing only when the view has finished to slide in....? Again, I'm obviously doing something wrong here, any help would be appreciated :)

Thx for your time!

Answer 1

The code snippet

[[UINavigationBar appearance] setTintColor:[UIColor colorWithRed:107.0/256.0 green:145.0/256.0 blue:35.0/256.0 alpha:1.0]]; 

Will change the color of the navigation bar of whole app.

Just place it in Appdelegate's didFinishLauncing method.

Answer 2

Since iOS 5 you can do that directly with an UINavigationBar

https://developer.apple.com/library/ios/#documentation/UIKit/Reference/UINavigationBar_Class/Reference/UINavigationBar.html Customizing the Appearance of a Navigation Bar

Just set the titleTextAttributes dictionary

Answer 3

For iOS7 and later the solution is this:

[UINavigationBar appearance].barTintColor = [UIColor redColor];

paste this code in the AppDelegate (didFinishLaunching:) method, and everything should work just fine.

请不要在viewDidAppear方法中设置它，而是在viewDidLoad方法中执行此操作。
