Changing NavigationItem’s font - iphone

I have used this code to change a NavigationItem’s title:
self.navigationItem.title = #"My Name is ABC";
How can I change the font size and font as well?

Sample Code :
CGRect frame = CGRectMake(0, 0, 400, 44);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:8.0];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.text = #"Sample custom Title With small Fonts ";
self.navigationItem.titleView = label;

As of iOS5+, you can use the UIAppearance protocol to change the font of the nav title, here's code:
NSMutableDictionary *titleBarAttributes = [NSMutableDictionary dictionaryWithDictionary: [[UINavigationBar appearance] titleTextAttributes]];
[titleBarAttributes setValue:[UIFont fontWithName:#"Helvetica-Bold" size:18] forKey:UITextAttributeFont];
[[UINavigationBar appearance] setTitleTextAttributes:titleBarAttributes];

Since iOS5 you can use the new titleTextAttributes property like so:
NSMutableDictionary *newAttributes = [[NSMutableDictionary alloc] init];
[newAttributes setObject:[UIFont boldSystemFontOfSize:18] forKey:UITextAttributeFont];
[self.navigationController.navigationBar setTitleTextAttributes:newAttributes];
Possible keys are:
UITextAttributeFont
UITextAttributeTextColor
UITextAttributeTextShadowColor
UITextAttributeTextShadowOffset

To make the above example centered you have to have the size be only as wide as the text, this should do the trick
UIFont * font = [UIFont fontWithName:#"Helvetica" size:18.0f];
CGRect frame = CGRectMake(0, 0, [#"Lorem Ipsum" sizeWithFont:font].width, 44);

As of iOS5, you can do this in 1 line:
[[UINavigationBar appearance] setTitleTextAttributes: #{UITextAttributeFont: [UIFont fontWithName:#"Helvetica" size:20.0f]}];

Swift 4
in AppDelegate.swift
UIBarButtonItem.appearance().setTitleTextAttributes([NSAttributedStringKey.font: UIFont(name: "Helvetica-Bold", size: 15)!], for: .normal)

Here is the modern Swift 2 solution:
let customFont = UIFont(name: "Helvetica", size: 17)
UINavigationBar.appearance().titleTextAttributes = [NSFontAttributeName : customFont!]

//Appearance setup for navigation title font throught application...
let customFont = UIFont(name: "Helvetica-Bold", size: 15)
UINavigationBar.appearance().titleTextAttributes = [NSAttributedStringKey.font : customFont!]

I have found some good answer for this .I think it's similar to the accepted answer however please find it in some more detail.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self){
// this will appear as the title in the navigation bar
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:20.0];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor yellowColor]; // change this color
self.navigationItem.titleView = label;
label.text = NSLocalizedString(#"PageThreeTitle", #"");
[label sizeToFit];
}
return self;
}
For more details, Please refer this Link

For swift 3
self.navigationController?.navigationBar.titleTextAttributes = [NSFontAttributeName :UIfont(named:"test") ]

set the alignment of title of navigation bar

I'm trying to align the title of the navigation bar to the center in my app but it seems the title is staying on the right side (please find the screen shot). I'm using the code below:
-(void)viewDidLoad {
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithTitle:#"Home" style:UIBarButtonItemStylePlain target:self action:#selector(goToHomePage:)];
[self.navigationController.navigationItem.rightBarButtonItem setTarget:self];
self.navigationItem.rightBarButtonItem = addButton;
[addButton release];
}
in viewWillAppear() as below
[self.navigationItem setTitle:offertitle];
and tried this too
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(40, 0, 120, 40)];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:14.0];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = UITextAlignmentLeft;
label.textColor =[UIColor whiteColor];
label.text=offertit;
self.navigationItem.titleView = label;
the title displays center aligned title when I hide the back button. Is there any method to set the appearance attributes of back button?

Can anyone guide me where i may have gone wrong.
You don't have to use UILabel. You can directly use this code:
[self.navigationItem setTitle:#"Your Title"];
and you're good to go! This code will automatically lay its self to the center of the navigation bar.
Or if you actually have an instance of UINavigationController, use:
[self setTitle:#"Your Title"];
You need to set self.title = "" in the viewWillDisappear method in the previous viewcontroller.
Eg. ViewControllerB is opening from ViewControllerA then set self.title = "" in ViewControllerA's "viewWillDisappear" method
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
{
// this will appear as the title in the navigation bar
UILabel *label = [[[UILabel alloc] initWithFrame:CGRectZero] autorelease];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:20.0];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor yellowColor]; // change this color
self.navigationItem.titleView = label;
label.text = NSLocalizedString(#"PageThreeTitle", #"");
[label sizeToFit];
}
return self;
}
Just call this in ViewDidLoad
- (void)prepareNavigationTitle
{
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(-50, 0.0, 240.0, 40.0)];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:14.0];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = UITextAlignmentLeft;
label.textColor =[UIColor whiteColor];
label.text=offertit;
self.navigationItem.titleView = label;
}
If you have a navigation controller then just add: self.title=#"Your Title";
Try using self.navigationItem.title = #"YourTitle"; this code will place the title in the center of the navigation bar .

Using UIAppearance to change label height

Is there any way to use UIAppearance to change the height of a label inside of a UINavigationBar. Here's the code and an image of what's going on so you can understand what the problem is.
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:-5.0 forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:-5.0 forBarMetrics:UIBarMetricsLandscapePhone];
NSDictionary *textAttributes = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:[UIFont fontWithName:#"MarketingScript" size:34.0], nil]
forKeys:[NSArray arrayWithObjects:UITextAttributeFont, nil]];
I ended up solving this by creating a custom UIView:
+(NavigationBarTitleLabel *)titleLabelWithTitle:(NSString *)title {
// this will appear as the title in the navigation bar
NavigationBarTitleLabel *labelWrapper = [[NavigationBarTitleLabel alloc] initWithFrame:CGRectMake(0, 0, 200, 34)];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 8, 200, 32)];
label.font = [UIFont fontWithName:#"MarketingScript" size:28.0];
label.text = title;
label.textColor = XHEXCOLOR(0XFFFFFF);
label.textAlignment = UITextAlignmentCenter;
label.backgroundColor = [UIColor clearColor];
label.layer.shadowColor = [UIColor blackColor].CGColor;
label.layer.shadowRadius = 2;
[labelWrapper addSubview:label];
[labelWrapper sizeToFit];
return labelWrapper;
}
and then setting the titleView property on the navigationItem:
self.navigationItem.titleView = [NavigationBarTitleLabel titleLabelWithTitle:self.title];
Probably you can get the UIAppearance for UILabel inside UINavigationBar.

Customizing Title in the NavigationBar for a ABPeoplePickerNavigationController

I have created an AddressBook kind of application where I display a list of people in a UITableView, when a person is selected an ABUnknownPersonViewController is pushed. From this ABUnknownPersonViewController the user is able (by using the built in functionality) to either add the person to a "New Contact" or "Existing Contact".
This is where my problem is located. I am using a Custom UILabel for the NavigationBar title throughout my application. And I need to be able to do this for the views that are pushed by "Add New Contact" / "Add to Existing Contact" as well.
I solved this for the "Add New Contact" by creating a category for ABNewPersonViewController, but the same approach doesn't work for the "Add to Existing Contact". I guess this might be due to the fact that is it an ABPersonPickerNavigationController that is pushed.
#implementation ABPeoplePickerNavigationController (customTitle)
-(void)viewDidLoad {
[super viewDidLoad];
self.navigationBar.tintColor = [UIColor colorWithRed:102/255.0 green:102/255.0 blue:102/255.0 alpha:1];
}
The change of color for the NavigationBar's tintColor works fine, but I cant find a proper way to access the title. Help that include a working example where you are able to change the title in a ABPeoplePickerNavigationController that is pushed from a ABUnknownPersonViewController would be much appriciated.
This is how the category for ABNewPersonViewController (that works) looks like:
#implementation ABNewPersonViewController (customTitle)
-(void)viewDidLoad {
[super viewDidLoad];
self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:102/255.0 green:102/255.0 blue:102/255.0 alpha:1];
}
-(void)setTitle:(NSString *)theTitle {
CGRect frame = CGRectMake(0, 0, 45, 45);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont systemFontOfSize:20.0];
label.shadowColor = [UIColor colorWithWhite:255.0 alpha:1];
label.shadowOffset = CGSizeMake(1, 1);
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor colorWithRed:23/255.0 green:23/255.0 blue:23/255.0 alpha:1];
self.navigationItem.titleView = label;
label.text = theTitle;
[label sizeToFit];
}
#end
I use custom labels for this purpose. You can also change font size with this code.
Example:
UILabel * label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 320 / 11)];
label.font = 16.0;
label.textColor = [UIColor blackColor];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.backgroundColor = [UIColor clearColor];
label.textAlignment = UITextAlignmentCenter;
label.text = #"Your title";
self.navigationItem.titleView = label;
[label release];
Hope this helps.

UINavigationItem titleView position

I'm using UINavigationItem's titleView property to set a custom UILabel with my desired font size/color. Here's my code:
self.headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 400.0, 44.0)];
self.headerLabel.textAlignment = UITextAlignmentCenter;
self.headerLabel.backgroundColor = [UIColor clearColor];
self.headerLabel.font = [UIFont boldSystemFontOfSize:20.0];
self.headerLabel.textColor = [UIColor colorWithRed:0.259 green:0.280 blue:0.312 alpha:1.0];
self.navigationItem.titleView = self.headerLabel;
In the navigation bar I also have a left bar button. The result is: the text isn't properly centered. I've tried setting the x origin of the label, but this has no effect.
In stead of initWithFrame just use init and put [self.headerLabel sizeToFit] after your last line of code.
If you make the headerLabel a subview of the titleView, you can then set headerLabel's frame to control where it goes within the titleView.
The way you are doing it now, you don't have that control. I think the OS chooses the titleView's frame for you based on the space available.
Hope this helps!
I've used custom title labels for my nav bars in every app I have in the app store. I've tested many different ways of doing so and by far the easiest way to use a custom label in a navigation bar is to completely ignore titleView and insert your label directly into navigationController.view.
With this approach, it's easy to have the title label's frame always match the navigationBar's frame -- even if you are using a custom navBar with a non-standard size.
- (void)viewDidLoad {
[self.navigationController.view addSubview:self.titleLabel];
[super viewDidLoad];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
- (void)didRotateFromInterfaceOrientation:
(UIInterfaceOrientation)fromInterfaceOrientation {
[self frameTitleLabel];
}
- (UILabel *) titleLabel {
if (!titleLabel) {
titleLabel = [[UILabel alloc]
initWithFrame:self.navigationController.navigationBar.frame];
titleLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size:18];
titleLabel.text = NSLocalizedString(#"Custom Title", nil);
titleLabel.textAlignment = UITextAlignmentCenter;
titleLabel.lineBreakMode = UILineBreakModeTailTruncation;
}
return titleLabel;
}
- (void) frameTitleLabel {
self.titleLabel.frame = self.navigationController.navigationBar.frame;
}
The one caveat to this approach is that your title can flow over the top of any buttons you have in the navBar if you aren't careful and set the title to be too long. But, IMO, that is a lot less problematical to deal with than 1) The title not centering correctly when you have a rightBarButton or 2) The title not appearing if you have a leftBarButton.
I have a same problem; I just somehow solved this issue by calculating the title length and set the label frame width accordingly. Although this is not a perfect one but can be manageable. Here is the code.
label = [[UILabel alloc] init];
label.backgroundColor = [UIColor clearColor];
label.font = [ UIFont fontWithName: #"XXII DIRTY-ARMY" size: 32.0 ];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.0f];
label.textAlignment = UITextAlignmentCenter;
label.textColor =[UIColor orangeColor];
//label.text=categoryTitle;
CGFloat verticalOffset = 2;
NSString *reqSysVer = #"5.0";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
if ([currSysVer compare:reqSysVer options:NSNumericSearch] != NSOrderedAscending)
{
if (categoryTitle.length > 8)
{
label.frame = CGRectMake(0, 0, 300, 44);
}else {
label.frame = CGRectMake(0, 0, 80, 44);
}
self.navigationItem.titleView = label;
self.navigationItem.title=label.text;
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:verticalOffset forBarMetrics:UIBarMetricsDefault];
[[UIBarButtonItem appearance] setTintColor:[UIColor newBrownLight]];
}
Just calculate exact frame size needed and align to left:
UIFont* font = [UIFont fontWithName:#"Bitsumishi" size:20];
CGSize maximumLabelSize = CGSizeMake(296,9999);
CGSize expectedLabelSize = [title sizeWithFont:font constrainedToSize:maximumLabelSize lineBreakMode:UILineBreakModeCharacterWrap];
CGRect frame = CGRectMake(0, 0, expectedLabelSize.width, expectedLabelSize.height);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.font = font;
label.textAlignment = UITextAlignmentLeft;
label.text = title;
self.titleView = label;
UIView *vw = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 40)];
lbl.text = #"Home";
lbl.textAlignment = UITextAlignmentCenter;
lbl.backgroundColor = [UIColor clearColor];
lbl.textColor = [UIColor whiteColor];
lbl.font = [UIFont fontWithName:#"HelveticaNeue-Bold" size:20];
lbl.shadowColor = [UIColor blackColor];
lbl.shadowOffset = CGSizeMake(0,1);
self.navigationItem.titleView = vw;
[self.navigationItem.titleView addSubview:lbl];
What worked for me was to update the titleView frame in the viewDidAppear method.
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
UIView *titleView = self.navigationItem.titleView;
CGRect navBarFrame = self.navigationController.navigationBar.frame;
[titleView setFrame:CGRectMake((CGRectGetWidth(navBarFrame) - TitleWidth) / 2, (CGRectGetHeight(navBarFrame) - TitleHeight) / 2, TitleWidth, TitleHeight)];
}
