自定义编辑菜单中的UIMenuItems顺序

我想将自己的命令添加到选择菜单中，但也保留标准的“复制”，“剪切”等命令。 我用这个：

UIMenuItem *myItem = [[UIMenuItem alloc] initWithTitle:@"My Command" action:@selector(myCommand:)]; [[UIMenuController sharedMenuController] setMenuItems:[NSArray arrayWithObjects: myItem, nil]]; 

但是这会将我的命令添加到编辑菜单中列表的最后。 我希望我的命令首先出现在其中。 我怎么能实现这个目标？

自己解决了。 这是我的initWithCoder:方法：

  UIMenuItem *myCommandItem = [[UIMenuItem alloc] initWithTitle:@"My Command" action:@selector(myCommandPressed:)]; UIMenuItem *cutItem = [[UIMenuItem alloc] initWithTitle:@"Cut" action:@selector(myCut:)]; UIMenuItem *copyItem = [[UIMenuItem alloc] initWithTitle:@"Copy" action:@selector(myCopy:)]; UIMenuItem *pasteItem = [[UIMenuItem alloc] initWithTitle:@"Paste" action:@selector(myPaste:)]; UIMenuItem *selectItem = [[UIMenuItem alloc] initWithTitle:@"Select" action:@selector(mySelect:)]; UIMenuItem *selectAllItem = [[UIMenuItem alloc] initWithTitle:@"Select all" action:@selector(mySelectAll:)]; UIMenuItem *deleteItem = [[UIMenuItem alloc] initWithTitle:@"Delete" action:@selector(myDelete:)]; [[UIMenuController sharedMenuController] setMenuItems:[NSArray arrayWithObjects: myCommandItem, cutItem, copyItem, pasteItem, selectItem, selectAllItem, deleteItem, nil]]; 

现在这个：

 - (BOOL)canPerformAction:(SEL)action withSender:(id)sender { if (action == @selector(myCommandPressed:)) { return YES; } if (action == @selector(myCut:)) { return [super canPerformAction:@selector(cut:) withSender:sender]; } if (action == @selector(myCopy:)) { return [super canPerformAction:@selector(copy:) withSender:sender]; } if (action == @selector(myPaste:)) { return [super canPerformAction:@selector(paste:) withSender:sender]; } if (action == @selector(mySelect:)) { return [super canPerformAction:@selector(select:) withSender:sender]; } if (action == @selector(mySelectAll:)) { return [super canPerformAction:@selector(selectAll:) withSender:sender]; } if (action == @selector(myDelete:)) { return [super canPerformAction:@selector(delete:) withSender:sender]; } return NO; } 

最后：

 - (void) myCommandPressed: (id) sender { NSLog(@"My Command pressed"); } - (void) myCut: (id) sender { [self cut:sender]; } - (void) myCopy: (id) sender { [self copy:sender]; } - (void) myPaste: (id) sender { [self paste:sender]; } - (void) mySelect: (id) sender { [self select:sender]; } - (void) mySelectAll: (id) sender { [self selectAll:sender]; } - (void) myDelete: (id) sender { [self delete:sender]; }
