How to Set Custom Fonts in Objective-C Using Xcode

Objective-C and IOS Programming: A Simplified Approach to Developing Apps for the iPhone and iPad

Are you looking to add some extra flair to your iOS app by customizing its font? Look no further! In this article, we will explore how to set custom fonts in Objective-C using Xcode.

Setting Custom Fonts in Objective-C

To get started, you'll need to create a category for the UIFont class. This allows you to add extra functionality without subclassing or changing the actual object. Let's call our category 'CustomFonts.'

To create the category, open your Xcode project and click on File > New > File. Choose Objective-C file, enter your category name (e.g., CustomFont), choose file type as Category, and class as UIFont. Click Next followed by Create.

Once you've created the category, open the header file (UIFont+CustomFonts.h) and declare a method that will set the custom font.

Here's an example of what the code might look like:

```objective-c

#import

@interface UIFont (CustomFonts)

+(UIFont *)setProductSansRegularFont;

@end

```

Now, open the implementation file (UIFont+CustomFonts.m) and implement the method:

```objective-c

#import 'UIFont+CustomFonts.h'

@implementation UIFont (CustomFonts)

+(UIFont *)setProductSansRegularFont {

return 'UIFont fontWithName:@'Product-Sans-Regular' size:17.0';

}

@end

```

This code sets the custom font to Product Sans Regular with a size of 17.0.

Using the Custom Font

To use your custom font in your iOS app, you'll need to import the category and call the method in your view controller or wherever you want to display the text.

Here's an example:

```objective-c

#import 'UIFont+CustomFonts.h'

UIViewController *viewController = ''UIViewController alloc' init';

UILabel *label = ''UILabel alloc' initWithFrame:CGRectMake(0, 0, 200, 50)';

label.text = @'Hello World!';

label.font = 'UIFont setProductSansRegularFont';

'label removeFromSuperview';

```

This code creates a view controller and a label with the custom font.

In this article, we've seen how to set custom fonts in Objective-C using Xcode. By creating a category for the UIFont class and implementing a method that sets the custom font, you can add some extra flair to your iOS app. Remember to import the category and call the method wherever you want to display the text.

So there you have it! With these simple steps, you can customize your iOS app's font in no time.
