在之前的开发中用到了UIMenuController这个类，发现一个小问题，记录下来，具体如下
UIMenuController *menu = [UIMenuController sharedMenuController];
menu.menuItems = @[
[[UIMenuItem alloc] initWithTitle:@"复制" action:@selector（copy:)],
[[UIMenuItem alloc] initWithTitle:@"删除" action:@selector(delete:)]
];
此处注意，如果响应事件名字这向上边那样命名的话，menu 显示的时候会多出来两个按钮，具体原因不是很清楚，猜想是与其默认名字有所冲突，另外将初始化menultems 方法注释的话，在- (BOOL)canPerformAction:(SEL)action withSender:(id)sender 方法内实现return (action == @selector(copy:) || action == @selector(delete:)，menu会显示拷贝和删除两个按钮，所以突然发现这也是实现UIMenuController 的一种方法，不过title 就是系统的
下面是我的UIMenuController 实现的具体方法
if (!ISNULLSTR(self.model.user_id)) {//首页
if ([self.model.user_id longLongValue] == [LoginManager shareLoginManager].loginResponse.user_id) {//自己发的动态
menu.menuItems = @[
[[UIMenuItem alloc] initWithTitle:@"复制" action:@selector(commentcopyed:)],
[[UIMenuItem alloc] initWithTitle:@"删除" action:@selector(commentdelete:)]
];
}else
{
if (!ISNULLARRAY(self.model.commentArray)) {
TT_DynamicStateCommentModel *commentModel = self.model.commentArray[self.tag-1];
if ([commentModel.user_id longLongValue] == [LoginManager shareLoginManager].loginResponse.user_id) {//别人发表的动态，自己发表的评论
menu.menuItems = @[
[[UIMenuItem alloc] initWithTitle:@"复制" action:@selector(commentcopyed:)],
[[UIMenuItem alloc] initWithTitle:@"删除" action:@selector(commentdelete:)]
];
}else
{
menu.menuItems = @[[[UIMenuItem alloc] initWithTitle:@"复制" action:@selector(commentcopyed:)],];
}
}
}
}
if (!ISNULLSTR(self.detailModel.user_id)) {//动态详情
if ([self.detailModel.user_id longLongValue] == [LoginManager shareLoginManager].loginResponse.user_id) {//自己发的动态
menu.menuItems = @[
[[UIMenuItem alloc] initWithTitle:@"复制" action:@selector(commentcopyed:)],
[[UIMenuItem alloc] initWithTitle:@"删除" action:@selector(commentdelete:)]
];
}else
{
if (!ISNULLARRAY(self.detailModel.commentArray)) {
TT_DynamicDetailCommentModel *commentModel = (TT_DynamicDetailCommentModel *)self.detailModel.commentArray[self.tag-1];
if ([commentModel.user_id longLongValue] == [LoginManager shareLoginManager].loginResponse.user_id) {//别人发表的动态，自己发表的评论
menu.menuItems = @[
[[UIMenuItem alloc] initWithTitle:@"复制" action:@selector(commentcopyed:)],
[[UIMenuItem alloc] initWithTitle:@"删除" action:@selector(commentdelete:)]
];
}else
{
menu.menuItems = @[[[UIMenuItem alloc] initWithTitle:@"复制" action:@selector(commentcopyed:)],];
}
}
}
}
[self showMenuView:menu];
DLog(@"长按评论。。。。。");
}
}
}
- (BOOL)canPerformAction:(SEL)action withSender:(id)sender
{
return (action == @selector(commentcopyed:) || action == @selector(commentdelete:) || action == @selector(commentNamecopyed:));
}
- (void)showMenuView:(UIMenuController *)menu
{
[menu setTargetRect:self.frame inView:self.superview];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(handleMenuWillShowNotification:)
name:UIMenuControllerWillShowMenuNotification
object:nil];
[menu setMenuVisible:YES animated:YES];
}
- (BOOL)canBecomeFirstResponse
{
return YES;
}
#pragma mark - Notifications
- (void)handleMenuWillHideNotification:(NSNotification *)notification {
self.backgroundColor = [UIColor clearColor];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:UIMenuControllerWillHideMenuNotification
object:nil];
}
- (void)handleMenuWillShowNotification:(NSNotification *)notification {
self.backgroundColor = [UIColor clearColor];

name:UIMenuControllerWillShowMenuNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
