iOS 自定义Label复制文字

最近项目开发中遇到要复制Label上的文字的需求，经过查阅资料整理开发。

下面是自己借鉴网上各位大神的方法实现自己的需求。

首先，创建自定义Label 集成UILabel

#import@interface LRCopyLabel : UILabel

@end

接着实现具体方法

@implementation LRCopyLabel

//拖拽

-(void)awakeFromNib {

[super awakeFromNib];

[self addLongPressGesture];

}

//手动创建

- (instancetype)initWithFrame:(CGRect)frame

{

if (self = [super initWithFrame:frame]) {

[self addLongPressGesture];

}

return self;

}

//添加长按手势

- (void)addLongPressGesture {

self.userInteractionEnabled = YES;

UILongPressGestureRecognizer * longGesture = [[UILongPressGestureRecognizer alloc]initWithTarget:self action:@selector(longAction:)];

[self addGestureRecognizer:longGesture];

}

//长按触发的事件

- (void)longAction:(UILongPressGestureRecognizer *)sender

{

if (sender.state == UIGestureRecognizerStateBegan) {

NSLog(@"长按手势已经触发");

//一定要调用这个方法

[self becomeFirstResponder];

//创建菜单控制器

UIMenuController * menuvc = [UIMenuController sharedMenuController];

UIMenuItem * menuItem1 = [[UIMenuItem alloc]initWithTitle:@"复制" action:@selector(firstItemAction:)];

menuvc.menuItems = @[menuItem1];

[menuvc setTargetRect:CGRectMake(self.bounds.size.width/2, self.bounds.origin.y-5, 0, 0) inView:self];

[menuvc setMenuVisible:YES animated:YES];

}

}

#pragma mark--设置每一个item的点击事件

- (void)firstItemAction:(UIMenuItem *)item

{

//通过系统的粘贴板，记录下需要传递的数据

UIPasteboard *pboard = [UIPasteboard generalPasteboard];

pboard.string = self.text;

}

#pragma mark--必须实现的关键方法

//自己能否成为第一响应者

- (BOOL)canBecomeFirstResponder

{

return YES;

}

//能否处理Action事件

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

{

if (action == @selector(firstItemAction:)) {

return YES;

}

return [super canPerformAction:action withSender:sender];

}
