How to change all UIButton fonts to custom font?

Question

Is there any way to do this? I want to have a custom font that I've downloaded to show on ever UIButton.

Solution 1

If you use IBOutletCollection then this should be direct.

@property (nonatomic, retain) IBOutletCollection(UIButton) NSArray *buttons;

Connect the buttons to this outlet collection and later alter the font in a single shot using,

[self setValue:[UIFont fontWithName:@"Helvetica" size:30] forKeyPath:@"buttons.font"];

Solution 2

One way you could do it is to subclass UIButton setup your desired font and use your subclass instead of UIButton.

Edit

//
//  MyUIButton.h
//

@interface MyUIButton : UIButton {

}
+ (id)buttonWithType:(UIButtonType)buttonType;
@end

//
//  MyUIButton.m
//


#import "MyUIButton.h"


@implementation MyUIButton

+ (id)buttonWithType:(UIButtonType)buttonType{
   UIButton *button = [UIButton buttonWithType:buttonType];
   [[button titleLabel] setFont:[UIFont fontWithName:@"Helvetica-Bold" size:12]];
   return button;
}

@end

Then just use it like this:

[MyUIButton buttonWithType:UIButtonTypeCustom]

The other thing you can try is writing a category for UIButton and overriding it there.

Edit2

    //
    //  UIButton+Font.h
    //

#import <Foundation/Foundation.h>

@interface UIButton (DefaultFontExtension)
+ (id)buttonWithType:(UIButtonType)buttonType;
@end


    //
    //  UIButton+Font.m
    //

#import "UIButton+Font.h"

@implementation UIButton (DefaultFontExtension)

+ (id)buttonWithType:(UIButtonType)buttonType{
       UIButton *button = [UIButton buttonWithType:buttonType];
       [[button titleLabel] setFont:[UIFont fontWithName:@"Helvetica-Bold" size:12]];
       return button;
    }

@end

Now just import "UIButton+Font.h" it will override the default UIButton settings.

https://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIButton_Class/UIButton/UIButton.html#//apple_ref/doc/uid/TP40006815

button.titleLabel.font = [UIFont fontWithName:FONT_NAME size:FONT_SIZE];

Apple's documentation is quite good. Try looking it up there first, then search SO, then search Google, then write a question. :)

Edit: Well, the easiest way is to replace any fontWithName parameters with a constant, such as a macro.

#define BUTTON_FONT_NAME @"Helevetica"

If you haven't done that, then you will have to replace them all.

Yes, I know that, but is there a way to change all fonts in all buttons at once?

[vburojevic]

I think you misunderstood me :) I want to know if there is avoid this: [code] button1.titleLabel.font = [UIFont fontWithName:FONT_NAME size:FONT_SIZE] button2.titleLabel.font = [UIFont fontWithName:FONT_NAME size:FONT_SIZE] button3.titleLabel.font = [UIFont fontWithName:FONT_NAME size:FONT_SIZE] [/code] So I don't have to change one by one, is there any way to set the default font for all UIButtons?

This would work, but will force you to replace all your UIButtons or add another method. So, regardless you will have to go through and make changes.

@Wikiboo: Just stuff it in a subclass and just set your custom class of all your UIButtons to that subclass. Edit: Just like Patrick said.

If you will use a category you will only have to import your category header file

Nice. I guess this is the least cumbersome way.

Technically, they are different fonts. The first argument will have to change. In Helvetica's case, it will be Helvetica-Bold. It is mostly predictable but isn't guaranteed. Take a look at the font names here.

What if you don't use IBOutletCollection?
