As it seems that it is not possible to apply a custom font through Interface Builder, I tried to define a new UILabel-derived class and set in its - (id)init method the custom font I'd like to use: this doesn't lead to the expected result as the font used at runtime seems to be still the 'Helvetica' (my custom font is 'african' and it works if set via code).
Here is my UILabel-derived snippet:
- (id)init {
UIFont *font = [UIFont fontWithName:#"african" size:10];
[self setFont:font];
return self;
}
Therefore I'm currently solving the problem by forcing the font via code:
NSLog(#"Before FONT NAME IS ------------> %#", myLabel.font.fontName);
UIFont *font = [UIFont fontWithName:#"african" size:10];
[myLabel setFont:font];
myLabel.text = #"HELLO!";
NSLog(#"After FONT NAME IS ------------> %#", myLabel.font.fontName);
The printout is the following:
Before FONT NAME IS ------------> Helvetica
After FONT NAME IS ------------> African
It seems that the default font I set in the init method is overwritten: where else should I set it?
If you use your init function like that "self" will have no value… All init functions have to look like this
- (id)init {
self = [super init];
if (self) {
// Your init code here
}
return self;
}
Additionally make sure you'll override "initWithFrame:" too, and perhaps "initWithCoder:" if you want to use it from IB.

I'm using Constantia font family in my app, regular bold and italic style is my requirement, the problem I am facing is, I can only get output of regular style, and not the bold and italic, I've already added all three styled fonts into app, and in plist file under Fonts provided by application section. I tried with following
UIFont *bFont = [UIFont fontWithName:#"Constantia-Bold" size:24.0];
UIFont *bFont = [UIFont fontWithName:#"ConstantiaBold" size:24.0];
UIFont *bFont = [UIFont fontWithName:#"Constantia_Bold" size:24.0];
UIFont *iFont = [UIFont fontWithName:#"Constantia-Italic" size:24.0];
UIFont *iFont = [UIFont fontWithName:#"ConstantiaItalic" size:24.0];
UIFont *iFont = [UIFont fontWithName:#"Constantia_Italic" size:24.0];
but not a single case is working, only UIFont *font = [UIFont fontWithName:#"Constantia" size:24.0]; is working. I know that I'm missing something in font name only.
I tried find font into Mac font's option, I got this font under All Fonts section (left top), one strange this I found is, all Constantia bold, italic and regular are installed as a single name, i.e. Constantia only.
P.S. Fonts can be downloaded from here.
This is Step for, How to add custom font in Application.
1 - Add .TTF font in your application
2 - Modify the application-info.plist file.
3 - Add the key "Fonts provided by application" to a new row
4 - and add each .TTF file (of font) to each line.
For more info read This and This site.
For Bold
// Equivalent to [UIFont fontWithName:#"FontName-BoldMT" size:17]
UIFont* font = [UIFont fontWithFamilyName:#"FontName" traits:GSBoldFontMask size:17];
And bold/italic
UIFont* font = [UIFont fontWithMarkupDescription:#"font-family: FontName; font-size: 17px; font-weight: bold/italic;"]; // set here, either bold/italic.
Here is how you can see the real name of every font available for use by your app:
// Log fonts
for (NSString *family in [UIFont familyNames])
{
NSLog(#"Font family %#:", family);
for (NSString *font in [UIFont fontNamesForFamilyName:family])
NSLog(" %#", font);
}

for (NSString *fontFile in [[NSBundle mainBundle] pathsForResourcesOfType:#"ttf" inDirectory:nil])
{
if ([fontFile rangeOfString:#"_"].location != NSNotFound && verizon) {
newFontCount += GSFontAddFromFile([fontFile UTF8String]);
}
if ([fontFile rangeOfString:#"-"].location != NSNotFound && !verizon) {
newFontCount += GSFontAddFromFile([fontFile UTF8String]);
}
}
}
}
}
return newFontCount;
}
I'm using the function usually :)
I don't think such type of font is exist in IOS. Please check from here http://iosfonts.com/
How to change the Font of the Placeholder of the text filed?
Is this possible to change the default font of the Placeholder of the text filed?
If anyone know it please help me.
Thanks.
Create a subclass of UITextField and overwrite the drawPlaceholderInRect:
- (void) drawPlaceholderInRect:(CGRect)rect {
[[self placeholder] drawInRect:rect withFont:[UIFont systemFontOfSize:16.0]];
}
#fannheyward's answer was good. However, – drawInRect:withFont: is deprecated in iOS 7.0. In iOS 7, you should use:
- (void) drawPlaceholderInRect:(CGRect)rect {
UIFont *font = [UIFont fontWithName:#"STHeitiTC-Light" size:14.0];
[self.placeholder drawInRect:rect withAttributes:#{NSFontAttributeName: font}]
}
please also note that the "real" font name may be different from the one it shows on interface builder. You can use the following code to get the "real" name of available fonts in your project:
for (NSString *familyName in [UIFont familyNames]) {
for (NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) {
NSLog(#"%#", fontName);
}
}
I want to change the font of label. And font which i am using is shown in image.
How use it in my application. I have already add in .plist as show in image. But it not working proper. How i manage it?
Thanks in advances...
Use this to set the font programmatically:
[TheLabelName setFont:[UIFont fontWithName:#"American Typewriter" size:18]];
Custom fonts in IOS
to set an label font just
yourLabel.font = [UIFont fontWithName:#"CloisterBlack" size:64.0];
If you want to use the standard font, then just as usually: you can set it in the interface builder for this label or programmatically for this label.
If you want to apply your custom font (according to the image you want that), then you can do smth. like
UIFont *font = [UIFont fontWithName:#"MyFont" size:20];
[label setFont:font];
Also you can explore this ref:
Can I embed a custom font in an iPhone application?
it might be useful in your case.
Add your custom font file .ttf in resourse and use every time when you want to display formatted font like
headLbl.font = [UIFont fontWithName:#"Museo-700" size:20.f];
Add a font in your resource directory like this image that you have already done now main thing you cann't wirte the name of the font that you have added as it is check my image font having name ROCKB.ttf but i have write the Rockwell-Bold so you have to check by what name it has been installed in your code then pick the name from there and then put that name in lable the font will reflect the label now.
label.font = [UIFont fontWithName:#"Rockwell-Bold" size:20];
and font family by this code NSArray *familyNames = [[NSArray alloc] initWithArray:[UIFont familyNames]];
NSArray *fontNames;
NSInteger indFamily, indFont;
for (indFamily=0; indFamily<[familyNames count]; ++indFamily)
{
NSLog(#"Family name: %#", [familyNames objectAtIndex:indFamily]);
fontNames = [[NSArray alloc] initWithArray:
[UIFont fontNamesForFamilyName:
[familyNames objectAtIndex:indFamily]]];
for (indFont=0; indFont<[fontNames count]; ++indFont)
{
NSLog(#" Font name: %#", [fontNames objectAtIndex:indFont]);
}
[fontNames release];
}
[familyNames release];
Is there any way to How to Apply global font [new custom font] to whole application in iphone objective-c.
I know that we can use below method to set font for each label
[self.titleLabel setFont:[UIFont fontWithName:#"FONOT_NAME" size:FONT_SIZE]];
But I want to change for whole application.
Please help me if anyone know.
Apparently to change ALL UILabels altogether you will need to setup a category on UILabel and change the default font. So here's a solution for you:
Create a file CustomFontLabel.h
#interface UILabel(changeFont)
- (void)awakeFromNib;
-(id)initWithFrame:(CGRect)frame;
#end
Create a file CustomFontLabel.m
#implementation UILabel(changeFont)
- (void)awakeFromNib
{
[super awakeFromNib];
[self setFont:[UIFont fontWithName:#"Zapfino" size:12.0]];
}
-(id)initWithFrame:(CGRect)frame
{
id result = [super initWithFrame:frame];
if (result) {
[self setFont:[UIFont fontWithName:#"Zapfino" size:12.0]];
}
return result;
}
#end
Now ... in any view controller you want these custom font labels, just include at the top:
#import "CustomFontLabel.h"
That's all - good luck
Ican's solution with category might be prefered just to save the day. But avoid using category to override existing methods as apple explains:
Avoid Category Method Name Clashes
... If the name of a method declared in a category is the same as a method in the original class, or a method in another category on the same class (or even a superclass), the behavior is undefined as to which method implementation is used at runtime. ...
Note also that overriding -(id) init; would be safer than overriding -(id)initWithFrame:(CGRect)frame. You would not face with the problem of not receiving touch events when clicking on a label on UIButtons.
Is this what you mean?
#interface GlobalMethods
+(UIFont *)appFont;
#end
#implementation GlobalMethods
+(UIFont *)appFont{
return [UIFont fontWithName:#"someFontName" size:someFontSize];
}
#end
...
[self.titleLabel setFont:[GlobalMethods appFont]];
In case you want to do it somehow automatically (without using setFont on each control), I don't believe it's possible.
If you can limit your application – or this particular feature – to iOS 5, there’s a new API coming that lets you skin the default UI very conveniently. I can’t give you details, since they are still under NDA at the time I am writing this. Take a look at iOS 5 beta SDK to find out more.
CustomLabel.h
#import <UIKit/UIKit.h>
#interface VVLabel : UILabel
#end
CustomLabel.m
#import "CustomLabel.h"
#define FontDefaultName #"YourFontName"
#implementation VVLabel
- (instancetype)initWithCoder:(NSCoder *)aDecoder {
self = [super initWithCoder: aDecoder];
if (self) {
// Initialization code
// Static font size
self.font = [UIFont fontWithName:FontDefaultName size:17];
// If you want dynamic font size (Get font size from storyboard / From XIB then put below line)
self.font = [UIFont fontWithName:FontDefaultName size:self.font.pointSize];
}
return self;
}
Im extending the UIButton Class to be able to set the font and color of the UINavigationBarButton ( from this code example: switch on the code )
I goes like this:
#interface NavBarButtonGrey : UIButton
-(id)init;
#end
#implementation NavBarButtonGrey
-(id)init {
if(self = [super init]) {
self.frame = CGRectMake(0, 0, 49.0, 30.0);
self.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
self.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
UIImage *image = [UIImage imageNamed:#"greyNavButton.png"];
UIImage *stretchImage =
[image stretchableImageWithLeftCapWidth:15.0 topCapHeight:0.0];
[self setBackgroundImage:stretchImage forState:UIControlStateNormal];
self.backgroundColor = [UIColor clearColor];
[self setTitleShadowColor:[UIColor blackColor] forState:UIControlStateNormal];
self.titleShadowOffset = CGSizeMake(0, -1);
self.titleLabel.font = [UIFont boldSystemFontOfSize:13];
}
return self;
}
#end
This is ok, but of course not very flexible.
How do I incorporate using a typedef enum (like Apple does) for all the different
colors, fonts and sizes I would like my custom button to conform to.
The only thing I can get out of the interface files from UIKit is that it is done like this:
typedef enum {
RGCustomNavBarButtonStyleBlue,
RGCustomNavBarButtonStyleGrey,
RGCustomNavBarButtonStyleBlack,
RGCustomNavBarButtonStyleGreen,
RGCustomNavBarButtonStyleRed,
} RGCustomNavBarButtonStyle;
How to get from that and into a working implementation that takes font, size, color etc. from the values of the enum through the constructor(initWithStyle)?
Does one overload constructors in Objective C? multiple constructors?
Hope it makes sense and thank you for any help given:)
To expand on what ennuikiller said above, I was taught (Hillegass's book) to pick one initializer—usually the one with the most options, like your initWithFont:andColor:—and have the other initializers call it. That main initializer is referred to as the designated initializer.
So your code would have a fully-implemented initWithFont:andColor: that calls [super init], and then you'd also have an initWithFont: that looks something like this:
-(MyClass) initWithFont: (UIFont) font
{
[self initWithFont:font andColor:RGCustomNavBarButtonStyleBlack];
}
Then your initWithFont:andColor: would handle all the other setup and calling [super init].
You can have multiple constructors such as;
-(MyClass) initWithFont: (UIFont) font;
-(MyClass) initWithFonmt: (UIFont) font andColor: (UIColor) color;
etc.
Then call [super init] as the first line in each of your custom constructors.
