How can I change the font of labels with one command

if i have 3 labels called total, score and name and i want to change the font of the text i use this command

[total setFont:[UIFont fontWithName:@"Times New Roman" size:22]];
[score setFont:[UIFont fontWithName:@"Times New Roman" size:22]];
[name setFont:[UIFont fontWithName:@"Times New Roman" size:22]];

What if I have more than 20 labels in one view and all with different names like the common name of the score.

Is there a shorter way to change the font for all of them to the same font type?

make a quick listing.



 for( UIView *view in self.subviews)
    {
    if([view isKindOfClass:[UILabel Class]])
    {
    [(UILabel *)view setFont:[UIFont fontWithName:@"Times New Roman" size:22]];

    }
    }

For a specific label;



    for( UIView *v in self.view.subviews) {
        if([v isKindOfClass:[UILabel Class]]) {
            if (v.tag == 1453)
               [(UILabel *)v setFont:[UIFont fontWithName:@"Times New Roman" size:22]];
        }
    }

in .h

UIFont * myCustomFont;

in .m

myCustomFont = [UIFont fontWithName: @ "Times New Roman" size: 22];

[Name setFont: myCustomFont]; // Name is your UILabel //

Or directly in the prifix.pch file to execute the project.

This effect can be achieved also through the UILabel category using the Swizzling method: http://darkdust.net/writings/objective-c/method-swizzling#Step_2:_Create_the_wrapper_method

Title:

#import <UIKit/UIKit.h>

@interface UILabel (Swizzling)

- (UIFont *)swizzledFont;

@end

Implementation:

#import "UILabel+Swizzling.h"
#import <objc/runtime.h>

@implementation UILabel (Swizzling)

- (UIFont *)swizzledFont
{
    return [UIFont fontWithName:@"SourceSansPro-Light" size:[[self swizzledFont] pointSize]];
}

+ (void)load
{
    Method original, swizzled;

    original = class_getInstanceMethod(self, @selector(font));
    swizzled = class_getInstanceMethod(self, @selector(swizzledFont));
    method_exchangeImplementations(original, swizzled);
}

@end

Override UIFont

as such:

Create UIFont+SytemFontOverride.h

:

#import <UIKit/UIKit.h>

@interface UIFont (SytemFontOverride)
@end

and UIFont+SytemFontOverride.m

:

#import "UIFont+SytemFontOverride.h"
@implementation UIFont (SytemFontOverride)

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wobjc-protocol-method-implementation"

+ (UIFont *)boldSystemFontOfSize:(CGFloat)fontSize {
    return [UIFont fontWithName:@"Bryant-Bold" size:fontSize];
}

+ (UIFont *)systemFontOfSize:(CGFloat)fontSize {
    return [UIFont fontWithName:@"Bryant-Regular" size:fontSize];
}

#pragma clang diagnostic pop

@end

Change the font names accordingly.
