如何动态调整NSMenu的大小到其内容？

Question

我有像这样的标准NSMenu

此菜单是使用以下代码创建的：

NSMenu *menu = [[NSMenu alloc] init];

    NSMenuItem *addMenuItem = [[NSMenuItem alloc] init];
    [addMenuItem setTitle:[NSString stringWithFormat:@"Upload"]];
    [addMenuItem setHidden:NO];
    [addMenuItem setRepresentedObject:contentType];
    [addMenuItem setTarget:self];
    [addMenuItem setAction:@selector(performSelectedDragOperation:)];
    [addMenuItem setTag:operation];
    [addMenuItem setEnabled:YES];

    [menu addItem:addMenuItem];

    NSMenuItem *alterMenuItem = [addMenuItem copy];
    [alterMenuItem setTitle:@"Upload in Folder"];
    [alterMenuItem setKeyEquivalentModifierMask:NSAlternateKeyMask];
    [alterMenuItem setAlternate:YES];
    [menu addItem:alterMenuItem];
    [alterMenuItem release];

    [addMenuItem release];

    NSMenuItem *addMenuItem2 = [[NSMenuItem alloc] init];
    [addMenuItem2 setTitle:[NSString stringWithFormat:@"EditNewAndUpload"]];
    [addMenuItem2 setHidden:NO];
    [addMenuItem2 setRepresentedObject:contentType];
    [addMenuItem2 setTarget:self];
    [addMenuItem2 setAction:@selector(performSelectedDragOperation:)];
    [addMenuItem2 setTag:operation];
    [addMenuItem2 setEnabled:YES];

    [menu addItem:addMenuItem2];

    NSMenuItem *alterMenuItem2 = [addMenuItem2 copy];
    [alterMenuItem2 setTitle:@"EditNewAndUpload in Folder"];
    [alterMenuItem2 setKeyEquivalentModifierMask:NSAlternateKeyMask];
    [alterMenuItem2 setAlternate:YES];
    [menu addItem:alterMenuItem2];
    [alterMenuItem2 release];

    [addMenuItem2 release];

正如您所看到的，菜单中的每个选项都有一个“重复”项。当您按选项时显示该项目的副本（alt）键，菜单可见。

问题是菜单大小在显示备用菜单项时会发生变化，因为此菜单的标题大于原始标题，并且它永远不会恢复到原始大小，从而生成：

我知道如何解决它？ 感谢

这是正常行为，你不应该担心它。如果您想要更改，file a bug。

Answer 2

您只需要更改NSMenuItem标题

[[appmenu itemAtIndex：0] setTitle：[NSString stringWithFormat：@“EditNewAndUpload  \ t \ t \ t \ t \ t“]];
