纯属笔记学习

自定义button

//
//  MyButton.m
//  自定义控件纯代码布局 
//
//  Created by xuqing on 2023/3/15.
//

#import "MyButton.h"
@interface  MyButton()
@property(nonatomic ,weak)UILabel * numberLable;
@end

@implementation MyButton

- (void)setTitle:(NSString *)title num:(int)num{
    
 
}

- (instancetype)initWithFrame:(CGRect)frame{
    self= [super initWithFrame: frame];
    if(self){
        [self initViews];
    }
    return  self;
}

- (void)awakeFromNib{
    [super awakeFromNib];
    [self initViews];
    
}
-(void)initViews{
    UILabel *lable=[[UILabel alloc]init];
    lable.font=[UIFont systemFontOfSize:16];
    lable.textColor=[UIColor whiteColor];
    lable.backgroundColor=[UIColor redColor];
    [self addSubview:lable];
    self.numberLable=lable;
}
-(void)layoutSubviews{
    [super layoutSubviews];
    self.numberLable.frame=CGRectMake(10, 10, 16, 16);
   
}
@end

在viewcontroller 里面使用

//
//  ViewController.m
//  自定义空间纯代码
//
//  Created by xuqing on 2023/3/15.
//
#import "ViewController.h"
#import "MyButton.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
    MyButton * mybutton=[[MyButton alloc]init];
    [mybutton setTitle:@"系统消息" num:1];
    [mybutton setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
    mybutton.frame=CGRectMake(50, 400, 130, 65);
    [self.view addSubview:mybutton];
}
@end

最后总结

记录今天都学习 每天进步一点好好学习 天天向上
