如何动态调整 NSMenu 的大小以适应其内容？

Question

我有一个像这样的标准 NSMenu

此菜单是用以下代码创建的：

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];

如您所见，有一个“重复” " 菜单中每个选项的项目。当您在菜单可见的情况下按选项 (alt) 键时，会显示该项目的副本。

问题是菜单大小在显示备用菜单项时发生变化，因为该菜单的标题比原始菜单大，并且永远不会恢复到原始大小，从而产生以下内容：

知道如何修复它吗？ 谢谢

这是正常行为，您不必担心。如果您希望对其进行更改，请提交错误。

Answer 2

您只需要更改 NSMenuItem 标题

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