一，。

二，工程圖。

三，代碼。

RootViewController.h

#import <UIKit/UIKit.h>@interface RootViewController : UIViewController@end

 

RootViewController.m

#import "RootViewController.h"#import "Utils.h"@interface RootViewController ()@end@implementation RootViewController- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil{    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];    if (self) {        // Custom initialization    }    return self;}- (void)viewDidLoad{    [super viewDidLoad];    // Do any additional setup after loading the view.        //初始化背景圖    [self addView];        //初始化button    [self initButton];    }#pragma -mark -functions//初始化背景圖-(void)addView{    self.title=@"UIFont";}//初始化button-(void)initButton{    UIButton *rightButton = [[UIButton alloc] initWithFrame:CGRectMake(50, 100, 100, 50)];    [rightButton setTitleColor:[UIColor grayColor] forState:UIControlStateNormal];    rightButton.backgroundColor=[UIColor redColor];    //給按鈕上的字設定大小    [Utils setDefaultFont:rightButton size:20];    [rightButton setTitle:@"完成" forState:UIControlStateNormal];    [self.view addSubview:rightButton];}- (void)didReceiveMemoryWarning{    [super didReceiveMemoryWarning];    // Dispose of any resources that can be recreated.}

 

Utils.h

#import <Foundation/Foundation.h>@interface Utils : NSObject+ (void)setDefaultFont:(id)sender size:(float)size;@end

 

Utils.m

#import "Utils.h"@implementation Utils//給某個按鈕上的數字設定大小+ (void)setDefaultFont:(id)sender size:(float)size{    [sender setFont:[UIFont fontWithName:@"Helvetica" size:size]];}@end
