【代码笔记】关于UIFont的一些define

一，效果图。

二，工程图。

三，代码。

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. //初始化背景图
 [self addView]; //初始化button
 [self initButton]; } #pragma -mark -functions
//初始化背景图
-(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]; //给按钮上的字设置大小
    [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 //给某个按钮上的数字设置大小
+ (void)setDefaultFont:(id)sender size:(float)size{ [sender setFont:[UIFont fontWithName:@"Helvetica" size:size]]; } @end
