UINavigationBar needs to be transparent - ios

I have got UINavigationBar styling set in AppDelegate but it doesn't seem to be taking effect on my app. I am using XCode 5 and my code is as follows:
- (void) customizeApp
{
UIImage* menuBackground = [UIImage imageNamed:#"menu-bar.png"];
[[UINavigationBar appearance] setBackgroundImage:menuBackground forBarMetrics:UIBarMetricsDefault];
// Customize the title text for *all* UINavigationBars
[[UINavigationBar appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0],
UITextAttributeTextColor,
[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8],
UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"HelveticaNeue-Light" size:0.0],
UITextAttributeFont,
nil]];
}
Im not sure what Im doing wrong and why its not working. This was working in XCode 4/iOS6

[self.navigationController.navigationBar setBackgroundImage:menuBackground forBarMetrics:
UIBarMetricsDefault];

Can black navigationbar title color change?

My navigationBar is black:
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
but can not change textcolor in title, it has no effect, why?
NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], NSForegroundColorAttributeName, nil];
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];
Try using this code:
NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor],UITextAttributeTextColor,
[UIColor blackColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(-1, 0)], UITextAttributeTextShadowOffset, nil];
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];
Try this code.You can change your title color easily :)
self.navigationController.navigationBar.tintColor = White;
self.navigationController.navigationBarHidden=NO;
self.navigationItem.title = #"yourTitle";
[self.navigationController.navigationBar setTitleTextAttributes:
#{NSForegroundColorAttributeName:White}];
self.navigationController.navigationBar.barTintColor = [UIColor blackColor];
[[UINavigationBar appearance] setTitleTextAttributes:#{NSFontAttributeName:[UIFont fontWithName:kBoldFontName size:16],NSForegroundColorAttributeName:[UIColor blueColor]}];
It is working fine for me please try once.
I tried below code it is working fine.I am using Xcode 8 and iOS 10.2
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
self.navigationItem.title = #"your Title here";
[self.navigationController.navigationBar setTitleTextAttributes:
#{NSForegroundColorAttributeName:[UIColor greenColor]}];
self.navigationController.navigationBar.barTintColor = [UIColor lightGrayColor];

Is there a way to change title in navigation bar to Italic, Bold and underlined without changing font?

I use the UIAppearance to change attributes of my title in Navigation Bar like so:
[[UINavigationBar appearance] setTitleTextAttributes:#{NSForegroundColorAttributeName : [MM mainTitleColor]}];
But I have not found the way to make text underlined or italic, is there a way to do this without changing the font alltogether?
No. These properties you cant change unless font changing. Because the available keys under the appearance proxy are
UITextAttributeFont
UITextAttributeTextColor
UITextAttributeTextShadowColor
UITextAttributeTextShadowOffset
Change these properties to customize the UINavigationBar
If you looking for font change, then see the below example
[[UINavigationBar appearance] setTitleTextAttributes:#{
UITextAttributeTextColor: TEXT_COLOR,
UITextAttributeTextShadowColor: SHADOW_COLOR,
UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
UITextAttributeFont: [UIFont fontWithName:#"Arial-Bold" size:0.0],
}];
Try this one.
You have to customise your navigation controller with adding a imageview.
UIFont *yourFont = [UIFont fontWithName:#"Helvetica-BoldOblique" size:[UIFont systemFontSize]];
if ([[UINavigationBar class]respondsToSelector:#selector(appearance)]) {
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"myimage.png"] forBarMetrics:UIBarMetricsDefault];
}
[[UINavigationBar appearance] setTitleTextAttributes:#{
UITextAttributeTextColor : [UIColor clearColor],
UITextAttributeTextShadowColor : [UIColor blackColor],
UITextAttributeTextShadowOffset : [NSValue valueWithUIOffset:UIOffsetMake(1, 0)],
UITextAttributeFont : yourFont
}];
You can use :
Optima-BoldItalic
TimesNewRomanPS-BoldItalicMT
Baskerville-BoldItalic
HelveticaNeue-BoldItalic
TrebuchetMS-Bold
Helvetica-BoldOblique
You can try below code to make your text italic and bold.
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
shadow.shadowOffset = CGSizeMake(0, 1);
[[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName,
shadow, NSShadowAttributeName,
[UIFont fontWithName:#"HelveticaNeue-BoldItalic" size:21.0], NSFontAttributeName, nil]];
[self setTitle:#"Title text"];

iOS 7.1 Black Nav Bar with bright colors

This is how the Navigation Bar in my App looks like:
This is how I want it to look like (iTunes App, video page):
What can I do to achieve this bright colorful blur effect in my navigation bar?
Here's the code I use so far:
navigationController.navigationBar.barTintColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5];
navigationController.navigationBar.tintColor = [UIColor colorWithRed:88.0/255.0 green:204.0/255.0 blue:249.0/255.0 alpha:1.0];
navigationController.navigationBar.translucent=YES;
NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:1 green:1 blue:1 alpha:1.0],UITextAttributeTextColor,
[UIColor clearColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(-1, 0)], UITextAttributeTextShadowOffset, nil];
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];
Set your navigationaBar style to Translucent.
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
self.navigationController.navigationBar.translucent = YES;

iOS 5: tabBarItem setTitleTextAttributes for selected vs unselected state

The attributes set for UITabBarItem UIControlStateNormal overrides of UIControlStateSelected!
[navigationCtrl.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [Util colorFromHex:#"474747"], UITextAttributeTextColor, [UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0], UITextAttributeTextShadowColor, [NSValue valueWithUIOffset:UIOffsetMake(1.0, 1.0)], UITextAttributeTextShadowOffset, nil] forState:UIControlStateNormal];
[navigationCtrl.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [Util colorFromHex:#"FCFCFC"],UITextAttributeTextColor, nil] forState:UIControlStateSelected];
Why?

iOS - Globally change navigation bar title color using appearance?

This crashes the app:
[[UINavigationBar appearance] setTitleColor:[UIColor darkGrayColor] forState:UIControlStateNormal];
Is there a way to do this using appearance?
This worked:
NSDictionary *textTitleOptions = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor darkGrayColor], UITextAttributeTextColor, [UIColor whiteColor], UITextAttributeTextShadowColor, nil];
[[UINavigationBar appearance] setTitleTextAttributes:textTitleOptions];
Here's an example of how to do this in Swift:
UINavigationBar.appearance().titleTextAttributes =
[NSFontAttributeName:UIFont(name:"Exo2-Bold", size: 18) as! AnyObject,
NSForegroundColorAttributeName:UIColor.whiteColor()]
That crashes the app before UINavigationBar doesn't have a title or state... Those are UIButton methods
You need
[[UINavigationBar appearance] setTintColor:[UIColor darkGrayColor]];
The #RyJ answer is great and worked for me. Thought I'd chip in that there's a good tutorial on this in Ray Wenderlich's site, titled (excuse the pun):
User Interface Customization in iOS 6
See the section Customizing UINavigationBar
Here's the code snippet for the navigation bar title, to change globally:
// Customize the title text for *all* UINavigationBars
[[UINavigationBar appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0],
UITextAttributeTextColor,
[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8],
UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
UITextAttributeTextShadowOffset,
[UIFont fontWithName:#"Arial-Bold" size:0.0],
UITextAttributeFont,
nil]];
One other minor point is that it seems there's a default shadow on the title bar, so to get rid of it, you can't just remove the attribute. Instead you have to set a shadow offset:
UITextAttributeTextShadowOffset : [NSValue valueWithUIOffset:UIOffsetMake(0, 0)]
for iOS 15
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = <PREFERRED BACKGROUND COLOR>
appearance.titleTextAttributes = [.foregroundColor : <PREFERRED TITLE COLOR>]
navigationBar.tintColor = <PREFERED TINT COLOR> //for bar buttons
navigationBar.standardAppearance = appearance;
navigationBar.scrollEdgeAppearance = navigationBar.standardAppearance
I used following code to change the title bar's color.
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor blackColor];
shadow.shadowOffset = CGSizeMake(1, 0);
NSDictionary *titleTextAttributes = #{NSForegroundColorAttributeName:[UIColor whiteColor],
NSShadowAttributeName:shadow};
[[UINavigationBar appearance] setTitleTextAttributes:titleTextAttributes];
Using modern syntax and code that actually runs, this is how to globally style your UINavigationBar title text:
NSShadow *navigationBarTitleShadow = [[NSShadow alloc] init];
navigationBarTitleShadow.shadowColor = [UIColor colorWithWhite:0.5
alpha:0.5];
navigationBarTitleShadow.shadowOffset = CGSizeMake(2.0, 2.0);
[[UINavigationBar appearance] setTitleTextAttributes:#{ NSForegroundColorAttributeName : [UIColor blackColor],
NSFontAttributeName : [UIFont fontWithName:#"Arial-BoldMT"
size:30.0],
NSShadowAttributeName : navigationBarTitleShadow }];
Note: NSShadow's shadowBlurRadius property is not respected.
Note: Shadows are so iOS 6. Don't ever use them.
