在之前的開發(fā)中用到了UIMenuController這個類莹菱，發(fā)現(xiàn)一個小問題吠卷，記錄下來蒜危，具體如下
UIMenuController *menu = [UIMenuController sharedMenuController];
menu.menuItems = @[
[[UIMenuItem alloc] initWithTitle:@"復(fù)制" action:@selector（copy:)],
[[UIMenuItem alloc] initWithTitle:@"刪除" action:@selector(delete:)]
];
此處注意她君，如果響應(yīng)事件名字這向上邊那樣命名的話域仇，menu 顯示的時候會多出來兩個按鈕，具體原因不是很清楚王暗，猜想是與其默認(rèn)名字有所沖突悔据，另外將初始化menultems 方法注釋的話，在- (BOOL)canPerformAction:(SEL)action withSender:(id)sender 方法內(nèi)實現(xiàn)return (action == @selector(copy:) || action == @selector(delete:)俗壹，menu會顯示拷貝和刪除兩個按鈕科汗，所以突然發(fā)現(xiàn)這也是實現(xiàn)UIMenuController 的一種方法，不過title 就是系統(tǒng)的
下面是我的UIMenuController 實現(xiàn)的具體方法
if (!ISNULLSTR(self.model.user_id)) {//首頁
if ([self.model.user_id longLongValue] == [LoginManager shareLoginManager].loginResponse.user_id) {//自己發(fā)的動態(tài)
menu.menuItems = @[
[[UIMenuItem alloc] initWithTitle:@"復(fù)制" action:@selector(commentcopyed:)],
[[UIMenuItem alloc] initWithTitle:@"刪除" 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) {//別人發(fā)表的動態(tài)绷雏，自己發(fā)表的評論
menu.menuItems = @[
[[UIMenuItem alloc] initWithTitle:@"復(fù)制" action:@selector(commentcopyed:)],
[[UIMenuItem alloc] initWithTitle:@"刪除" action:@selector(commentdelete:)]
