Adjust font size in Navigation Title - ios

Is there any way to make the font of the title of the navigation bar adjusted with the width?
Same behaviour as a [UILabel setAdjustsFontSizeToFitWidth:YES].
I'm trying setting the appearance of the NavigationBar, but no success so far.

Try doing something like:
self.navigationItem.titleView = titleLabel;
where titleLabel is a custom UILabel that you've initialized and customized.
Check out this Fontful code, for example.

There's no way to do this with the standard title item. You can still add your custom UILabel to the navigation bar and take care of the title changes.

You can not change the font of title.
Instead try out this..
self.title = #"My title is this.";
CGRect frame = CGRectMake(0, 0, [self.title sizeWithFont:[UIFont boldSystemFontOfSize:20.0]].width, 44);
UILabel *label = [[UILabel alloc] initWithFrame:frame];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:17.0];
label.textAlignment = UITextAlignmentCenter;
self.navigationItem.titleView = label;
label.text = self.title;
[label release];

Shifting the text of UINavigationBar title left or right

I would like to be able to control the position of the title in a UInavigationBar. For example, right now my titles are centered, but for some views, I need to shift the title origin a few px to the left or so. Is this possible?
Thank you!
You can add a custom titleView to your navigation item, and place an off-center UILabel in it to hold your title. Another easier way, might be to just append a space character or two to the end of your title if that gives you the amount of displacement you need.
your code here
- (void) customNavBarTitleWithText:(NSString *) text andFontsize:(float) fontsize
{
// Custom nav bar back button
UIImage *img = [UIImage imageNamed:#"back_btn.png"];
UIButton *backbtn = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, img.size.width, img.size.height)];
[backbtn setImage:img forState:UIControlStateNormal];
[backbtn addTarget:self action:#selector(backBtnClicked) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backBarBtn = [[UIBarButtonItem alloc] initWithCustomView:backbtn];
[self.navigationItem setLeftBarButtonItem:backBarBtn];
//Custom nav bar title
UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:fontsize];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = NSTextAlignmentCenter;
// Use UITextAlignmentCenter for older SDKs.
label.textColor = [UIColor whiteColor]; // change this color
self.navigationItem.titleView = label;
label.text = text;
label.lineBreakMode = NSLineBreakByWordWrapping;
label.numberOfLines = 0;
[label sizeToFit];
// Set nav bar background image
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"top_bar_bg.png"] forBarMetrics:UIBarMetricsDefault];
}
in there:
label.textAlignment = NSTextAlignmentCenter;
you can use another mode: NSTextAlignmentLeft, NSTextAlignmentRight, NSTextAlignmentJustified, etc..
Hope it work for you!

Centering UINavigationBar title text issue

In my UINavigationBar I have a multi line title, I am using the following the code to setup:
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 480, 50)];
label.backgroundColor = [UIColor clearColor];
label.numberOfLines = 2;
label.font = [UIFont boldSystemFontOfSize: 15.0f];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = NSTextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.text = #"Headloss due to Friction (Hazen Williams Eq.)";
self.navigationItem.titleView = label;
Since this is on a sub-view it has a "Back" button, added by the UINavigationController. So I figured that by adding the label.textAlignment = NSTextAlignmentCenter; my title would be centered, but it's actually centering my title from the end of my "Back" button to the end of my screen.
How can I override this so that my title is actually centered based on my screen dimension, (basically, the way it would be by default should the back button not be present).
Good question that's pretty tough. If I find a more elegant solution I'll edit my answer but this is what I came up with:
UIView *spaceView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 30, 20)];
UIBarButtonItem *space = [[UIBarButtonItem alloc] initWithCustomView:spaceView];
self.navigationItem.rightBarButtonItems = [NSArray arrayWithObject:space];
And just adjust the width of the UIView for how far you want your titleLabel to move.

UITableView controller removes custom NavBar TitleView

I have a bit of code that allows me to customize the Navigation Bar title of a view to allow for shrinking / truncating of long titles. The code works fine almost everywhere, however when it's used in a UITableViewController, the title never appears.
The code in question is:
- (void)viewDidLoad
{
[super viewDidLoad];
//Nav bar title for truncating longer titles
CGRect frame = CGRectMake(0, 0, 400, 44);
UILabel *label = [[UILabel alloc] initWithFrame:frame];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont boldSystemFontOfSize:20.0];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.adjustsFontSizeToFitWidth = YES;
label.minimumFontSize = 10.0f;
label.lineBreakMode = UILineBreakModeTailTruncation;
label.text = #"This is a really long title. It will shrink and eventually get truncated correctly.";
self.navigationItem.titleView = label;
}
I've put together a small demo project that illustrates the problem.
https://sites.google.com/site/coffeestainit/files/NavTitleError.zip
I just went through your project. The problem is that in your storyboard, you have not connected your tableViewController to the FirstViewController. So the viewDidLoad of the
FirstViewController is never called.
When I set the custom class of your TableViewController to FirstViewController in the storyboard, it set the label as title, as expected

Set a navigation button for the title of a UINavigationBar

I want to make a standard navigation bar button for my bar's title. I can set a custom view. In the sample below, I've done this with a UILabel. But I don't see how to make a standard navigation button.
-(void) setTitleButtonWithText: (NSString*) text {
self.title = text;
UIFont* font = [UIFont boldSystemFontOfSize:18];
CGSize size = [text sizeWithFont:font];
size.width+=6;
size.height+=6;
UILabel* titleLabel = [[UILabel alloc]init];
CGRect frame = CGRectZero;
frame.size = size;
self.navigationItem.titleView = titleLabel;
titleLabel.frame = frame;
titleLabel.textColor = [UIColor redColor];
titleLabel.text = text;
titleLabel.font = font;
}
titleView is a UIView property, so since UIBarButtonItem is not a UIView it cant be used here, as an alternative you could try making a UIButton with the same style and set that as the titleView

iPhone Navigation Bar Title text color

It seems the iOS Navigation Bar title color is white by default. Is there a way to change it to a different color?
I am aware of the navigationItem.titleView approach using an image. Since my design skills are limited and I failed to get the standard glossy, I prefer changing the text color.
Any insight would be much appreciated.
Modern approach
The modern way, for the entire navigation controller… do this once, when your navigation controller's root view is loaded.
[self.navigationController.navigationBar setTitleTextAttributes:
#{NSForegroundColorAttributeName:[UIColor yellowColor]}];
However, this doesn't seem have an effect in subsequent views.
Classic approach
The old way, per view controller (these constants are for iOS 6, but if want to do it per view controller on iOS 7 appearance you'll want the same approach but with different constants):
You need to use a UILabel as the titleView of the navigationItem.
The label should:
Have a clear background color (label.backgroundColor = [UIColor clearColor]).
Use bold 20pt system font (label.font = [UIFont boldSystemFontOfSize: 20.0f]).
Have a shadow of black with 50% alpha (label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5]).
You'll want to set the text alignment to centered as well (label.textAlignment = NSTextAlignmentCenter (UITextAlignmentCenter for older SDKs).
Set the label text color to be whatever custom color you'd like. You do want a color that doesn't cause the text to blend into shadow, which would be difficult to read.
I worked this out through trial and error, but the values I came up with are ultimately too simple for them not to be what Apple picked. :)
If you want to verify this, drop this code into initWithNibName:bundle: in PageThreeViewController.m of Apple's NavBar sample. This will replace the text with a yellow label. This should be indistinguishable from the original produced by Apple's code, except for the color.
- (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 = NSTextAlignmentCenter;
// ^-Use UITextAlignmentCenter for older SDKs.
label.textColor = [UIColor yellowColor]; // change this color
self.navigationItem.titleView = label;
label.text = NSLocalizedString(#"PageThreeTitle", #"");
[label sizeToFit];
}
return self;
}
Edit: Also, read Erik B's answer below. My code shows the effect, but his code offers a simpler way to drop this into place on an existing view controller.
I know this is a pretty old thread, but I think it would be useful to know for new users that iOS 5 brings a new property for establishing title properties.
You can use UINavigationBar's setTitleTextAttributes for setting the font, color, offset, and shadow color.
In addition you can set the same default UINavigationBar's Title Text Attributes for all the UINavigationBars throughout your application.
For example like so:
NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor],UITextAttributeTextColor,
[UIColor blackColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(-1, 0)], UITextAttributeTextShadowOffset, nil];
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];
In iOS 5 you can change the navigationBar title color in this manner:
navigationController.navigationBar.titleTextAttributes = #{NSForegroundColorAttributeName: [UIColor yellowColor]};
Based on Steven Fisher's answer I wrote this piece of code:
- (void)setTitle:(NSString *)title
{
[super setTitle:title];
UILabel *titleView = (UILabel *)self.navigationItem.titleView;
if (!titleView) {
titleView = [[UILabel alloc] initWithFrame:CGRectZero];
titleView.backgroundColor = [UIColor clearColor];
titleView.font = [UIFont boldSystemFontOfSize:20.0];
titleView.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
titleView.textColor = [UIColor yellowColor]; // Change to desired color
self.navigationItem.titleView = titleView;
[titleView release];
}
titleView.text = title;
[titleView sizeToFit];
}
The advantage of this code, besides dealing with the frame properly, is that if you change the title of your controller the custom title view will also get updated. No need to update it manually.
Another big advantage is that it makes it really simple to enable custom title color. All you need to do is to add this method to the controller.
Most of the above suggestions are deprecated now, for iOS 7 use -
NSDictionary *textAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor],NSForegroundColorAttributeName,
[UIColor whiteColor],NSBackgroundColorAttributeName,nil];
self.navigationController.navigationBar.titleTextAttributes = textAttributes;
self.title = #"Title of the Page";
Also, checkout the NSAttributedString.h for various text properties that could be set.
In IOS 7 and 8, you can change the Title's color to let's say green
self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor greenColor] forKey:NSForegroundColorAttributeName];
To keep the question up-to-date, I'll add Alex R. R. solution, but in Swift:
self.navigationController.navigationBar.barTintColor = .blueColor()
self.navigationController.navigationBar.tintColor = .whiteColor()
self.navigationController.navigationBar.titleTextAttributes = [
NSForegroundColorAttributeName : UIColor.whiteColor()
]
Which results to:
Swift Version
I found most of you guys presented the answers of Objective_C version
I would like to implement this function by using Swift for anyone who needs it.
In ViewDidload
1.To make NavigationBar background becomes color (for example: BLUE)
self.navigationController?.navigationBar.barTintColor = UIColor.blueColor()
2.To make NavigationBar background becomes Image (for example : ABC.png)
let barMetrix = UIBarMetrics(rawValue: 0)!
self.navigationController?.navigationBar
.setBackgroundImage(UIImage(named: "ABC"), forBarMetrics: barMetrix)
3.To change NavigationBar title (for example :[Font:Futura,10] [Color:Red])
navigationController?.navigationBar.titleTextAttributes = [
NSForegroundColorAttributeName : UIColor.redColor(),
NSFontAttributeName : UIFont(name: "Futura", size: 10)!
]
(hint1: don't forget the "!" mark after the UIFont)
(hint2: there are lots of attributes of the title text, command click
the "NSFontAttributeName" you can enter the class and view keyNames
and the Objects types they required)
I hope I can help!:D
Method 1, set it in IB:
Method 2, one line of code:
navigationController?.navigationBar.barTintColor = UIColor.blackColor()
The solution by tewha works well if you are trying to change the color on a page, but I want to be able to change the color on every page. I made some small modifications so that it would work for all pages on a UINavigationController
NavigationDelegate.h
//This will change the color of the navigation bar
#import <Foundation/Foundation.h>
#interface NavigationDelegate : NSObject<UINavigationControllerDelegate> {
}
#end
NavigationDelegate.m
#import "NavigationDelegate.h"
#implementation NavigationDelegate
- (void)navigationController:(UINavigationController *)navigationController
willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
CGRect frame = CGRectMake(0, 0, 200, 44);//TODO: Can we get the size of the text?
UILabel* label = [[[UILabel alloc] initWithFrame:frame] 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];
//The two lines below are the only ones that have changed
label.text=viewController.title;
viewController.navigationItem.titleView = label;
}
#end
From iOS 5 onwards we have to set title text color and font of navigation bar using titleTextAttribute Dictionary(predefined dictionary in UInavigation controller class reference).
[[UINavigationBar appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor blackColor],UITextAttributeTextColor,
[UIFont fontWithName:#"ArialMT" size:16.0], UITextAttributeFont,nil]];
Short and sweet.
[[[self navigationController] navigationBar] setTitleTextAttributes:#{NSForegroundColorAttributeName: [UIColor redColor]}];
Use the code below in any view controller viewDidLoad or viewWillAppear method.
- (void)viewDidLoad
{
[super viewDidLoad];
//I am using UIColor yellowColor for an example but you can use whatever color you like
self.navigationController.navigationBar.titleTextAttributes = #{NSForegroundColorAttributeName: [UIColor yellowColor]};
//change the title here to whatever you like
self.title = #"Home";
// Do any additional setup after loading the view.
}
This is my solution based upon Stevens
Only real difference is I put some handling in for adjust the position if depending on the text length, seems to be similar to how apple do it
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(([self.title length] < 10 ? UITextAlignmentCenter : UITextAlignmentLeft), 0, 480,44)];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.font = [UIFont boldSystemFontOfSize: 20.0f];
titleLabel.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
titleLabel.textAlignment = ([self.title length] < 10 ? UITextAlignmentCenter : UITextAlignmentLeft);
titleLabel.textColor = [UIColor redColor];
titleLabel.text = self.title;
self.navigationItem.titleView = titleLabel;
[titleLabel release];
You may want to adjust the 10 value depending on your font size
Swift 4 & 4.2 version:
self.navigationController.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.green]
I ran into the problem with my nav buttons throwing the text out of center (when you only have one button). To fix that I just changed my frame size like so:
CGRect frame = CGRectMake(0, 0, [self.title sizeWithFont:[UIFont boldSystemFontOfSize:20.0]].width, 44);
I've customized the navigationBar's background image and left button item, and the gray title not fit the background. Then I use:
[self.navigationBar setTintColor:[UIColor darkGrayColor]];
to change the tint color to gray. And the title is white now! That's what I want.
Hope to help also :)
It's recommended to set self.title as this is used while pushing child navbars or showing title on tabbars.
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// create and customize title view
self.title = NSLocalizedString(#"My Custom Title", #"");
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
titleLabel.text = self.title;
titleLabel.font = [UIFont boldSystemFontOfSize:16];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.textColor = [UIColor whiteColor];
[titleLabel sizeToFit];
self.navigationItem.titleView = titleLabel;
[titleLabel release];
}
}
This is a pretty old thread but I think of providing answer for setting Color, Size and Vertical Position of Navigation Bar Title for iOS 7 and above
For Color and Size
NSDictionary *titleAttributes =#{
NSFontAttributeName :[UIFont fontWithName:#"Helvetica-Bold" size:14.0],
NSForegroundColorAttributeName : [UIColor whiteColor]
};
For Vertical Position
[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:-10.0 forBarMetrics:UIBarMetricsDefault];
Set Title and assign the attributes dictionary
[[self navigationItem] setTitle:#"CLUBHOUSE"];
self.navigationController.navigationBar.titleTextAttributes = titleAttributes;
This works for me in Swift:
navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.white]
self.navigationItem.title=#"Extras";
[self.navigationController.navigationBar setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:#"HelveticaNeue" size:21], NSFontAttributeName,[UIColor whiteColor],UITextAttributeTextColor,nil]];
Use like this for Orientation support
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,40)];
[view setBackgroundColor:[UIColor clearColor]];
[view setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight ];
UILabel *nameLabel = [[UILabel alloc] init];
[nameLabel setFrame:CGRectMake(0, 0, 320, 40)];
[nameLabel setBackgroundColor:[UIColor clearColor]];
[nameLabel setAutoresizingMask:UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin |UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin];
[nameLabel setTextColor:[UIColor whiteColor]];
[nameLabel setFont:[UIFont boldSystemFontOfSize:17]];
[nameLabel setText:titleString];
[nameLabel setTextAlignment:UITextAlignmentCenter];
[view addSubview:nameLabel];
[nameLabel release];
self.navigationItem.titleView = view;
[view release];
to set font size of title i have used following conditions.. maybe helpfull to anybody
if ([currentTitle length]>24) msize = 10.0f;
else if ([currentTitle length]>16) msize = 14.0f;
else if ([currentTitle length]>12) msize = 18.0f;
An update to Alex R. R.'s post using the new iOS 7 text attributes and modern objective c for less noise:
NSShadow *titleShadow = [[NSShadow alloc] init];
titleShadow.shadowColor = [UIColor blackColor];
titleShadow.shadowOffset = CGSizeMake(-1, 0);
NSDictionary *navbarTitleTextAttributes = #{NSForegroundColorAttributeName:[UIColor whiteColor],
NSShadowAttributeName:titleShadow};
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];
I do believe proper way to set the colour of UINavigationBar is:
NSDictionary *attributes=[NSDictionary dictionaryWithObjectsAndKeys:[UIColor redColor],UITextAttributeTextColor, nil];
self.titleTextAttributes = attributes;
Code above is written is subclass on UINavigationBar, obviously works without subclassing as well.
This is one of those things that are missing. Your best bet is to create your own custom Navigation Bar, add a text box, and manipulate the color that way.
After encountering the same problem (as others) of the label that moves when we insert a button in the navBar (in my case i have a spinner that i replace with a button when the date is loaded), the above solutions didn't work for me, so here is what worked and kept the label at the same place all the time:
- (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
//CGRect frame = CGRectMake(0, 0, [self.title sizeWithFont:[UIFont boldSystemFontOfSize:20.0]].width, 44);
CGRect frame = CGRectMake(0, 0, 180, 44);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] 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];
self.navigationItem.titleView = label;
label.text = NSLocalizedString(#"Latest Questions", #"");
[label sizeToFit];
}
return self;
You should call [label sizeToFit]; after setting the text to prevent strange offsets when the label is automatically repositioned in the title view when other buttons occupy the nav bar.
Can use this method in appdelegate file and can use at every view
+(UILabel *) navigationTitleLable:(NSString *)title
{
CGRect frame = CGRectMake(0, 0, 165, 44);
UILabel *label = [[[UILabel alloc] initWithFrame:frame] autorelease];
label.backgroundColor = [UIColor clearColor];
label.font = NAVIGATION_TITLE_LABLE_SIZE;
label.shadowColor = [UIColor whiteColor];
label.numberOfLines = 2;
label.lineBreakMode = UILineBreakModeTailTruncation;
label.textAlignment = UITextAlignmentCenter;
[label setShadowOffset:CGSizeMake(0,1)];
label.textColor = [UIColor colorWithRed:51/255.0 green:51/255.0 blue:51/255.0 alpha:1.0];
//label.text = NSLocalizedString(title, #"");
return label;
}
titleTextAttributes
Display attributes for the bar’s title text.
#property(nonatomic, copy) NSDictionary *titleTextAttributes
Discussion
You can specify the font, text color, text shadow color, and text shadow offset for the title in the text attributes dictionary, using the text attribute keys described in NSString UIKit Additions Reference.
Availability
Available in iOS 5.0 and later.
