本文介绍如何在iOS应用中使用自定义MKBeCopyLabel类实现文本复制功能。通过创建一个可交互的UILabel子类，并为其添加长按手势识别器来触发文本复制操作。

一，效果图。

二，工程图。

三，代码。

ViewController.m

#import "ViewController.h"
#import "MKBeCopyLabel.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    MKBeCopyLabel *copyLabel = [[MKBeCopyLabel alloc]initWithFrame:CGRectMake(10, 100, 100, 60)];
    copyLabel.backgroundColor=[UIColor redColor];
    copyLabel.text=@"111111";
    copyLabel.userInteractionEnabled=YES;
    UITapGestureRecognizer *tapCopyText = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapToCopyText:)];
    [copyLabel addGestureRecognizer:tapCopyText];
    [self.view addSubview:copyLabel];

}
- (void)handleTapToCopyText:(UITapGestureRecognizer *)sender
{
    MKBeCopyLabel * targetLabel = (MKBeCopyLabel *)sender.view;
    [targetLabel handleLongTap];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end
