#import "CopyLabel.h"

@implementation CopyLabel

//控件初始化

- (instancetype)initWithFrame:(CGRect)frame {

    if (self = [superinitWithFrame:frame]) {

        [selfpressAction];

    }

    returnself;

}

//增加用户交互及长按手势

- (void)pressAction {

    self.userInteractionEnabled =YES;

    UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizeralloc] initWithTarget:selfaction:@selector(longPressAction:)];

    longPress.minimumPressDuration =1;

    [selfaddGestureRecognizer:longPress];

}

// 使label能够成为响应事件

- (BOOL)canBecomeFirstResponder

{

    returnYES;

}

// 控制响应的方法

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender

{

    return action ==@selector(customCopy:);

}

//响应长按手势
