- 自定义一个Widget，例如
XXLabel
- 实现
– (BOOL)canBecomeFirstResponder, 且返回YES
- 实现
– (BOOL)canPerformAction:withSender, 并根据需求返回YES或NO（貌似可以不用实现，简书不显示过期文字标签）
代码如下
#import "XXLabel.h"
@implementation XXLabel
- (void)awakeFromNib
{
[self addLongPressGesture];
}
- (BOOL)canBecomeFirstResponder
{
return YES;
}
#pragma mark - Private Method
- (void)addLongPressGesture
{
self.userInteractionEnabled = YES;
UILongPressGestureRecognizer *longPressGR = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressToCollection:)];
[self addGestureRecognizer:longPressGR];
}
- (void)longPressToCollection:(UIGestureRecognizer *)recognizer
{
[self becomeFirstResponder];
UIMenuItem *collection = [[UIMenuItem alloc] initWithTitle:@"收藏" action:@selector(collectionAction:)];
UIMenuController *menu = [UIMenuController sharedMenuController];
[menu setMenuItems:[NSArray arrayWithObjects:collection, nil]];
[menu setTargetRect:self.frame inView:self.superview];
[menu setMenuVisible:YES animated:YES];
}
- (void)collectionAction:(id)sender
{
// 使用Block或者代理
NSLog(@"点击了收藏");
}
@end
