#import "Cuslabel.h"

@implementation Cuslabel
(id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { [self attachTapHandler]; } return self; }

/*
 // Only override drawRect: if you perform custom drawing.
 // An empty implementation adversely affects performance during animation.
(void)drawRect:(CGRect)rect { // Drawing code } */

//为了能接收到事件（能成为第一响应者），我们需要覆盖一个方法：

-(BOOL)canBecomeFirstResponder
 {
 return YES;
 }

//还需要针对复制的操作覆盖两个方法：

// 可以响应的方法
 -(BOOL)canPerformAction:(SEL)action withSender:(id)sender
 {
 return (action == @selector(copy:));

}

//针对于响应方法的实现
 -(void)copy:(id)sender
 {
 UIPasteboard *pboard = [UIPasteboard generalPasteboard];
 pboard.string = self.text;
 }

//有了以上三个方法，我们就能处理copy了，当然，在能接收到事件的情况下：

//UILabel默认是不接收事件的，我们需要自己添加touch事件
 -(void)attachTapHandler
 {
 self.userInteractionEnabled = YES; //用户交互的总开关
 // UITapGestureRecognizer *touch = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
 // touch.numberOfTapsRequired = 2;
UILongPressGestureRecognizer  *jk=[[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(handleTap:)];
[self addGestureRecognizer:jk];


// [UIResponder ]

}
 //绑定事件
 -(void)handleTap:(UIGestureRecognizer*) recognizer
 {
 [self becomeFirstResponder];
 // UIMenuItem *copyLink = [[UIMenuItem alloc] initWithTitle:@"复制"
 // action:@selector(copy:)];
 // [[UIMenuController sharedMenuController] setMenuItems:[NSArray arrayWithObjects:copyLink, nil]];
 [[UIMenuController sharedMenuController ] setTargetRect:self.frame inView:self.superview];
 [[UIMenuController sharedMenuController] setMenuVisible:YES animated: YES];
 }
 //同上
 -(void)awakeFromNib
 {
 [super awakeFromNib];
 [self attachTapHandler];
 }
