macos - NSToolbarItem: "Make sure this toolbar item has a valid frame/min/max size"？

Question

自从升级到 Mac OS Sierra 和新的 XCode 版本后，每次为每个 NSToolbarItems 启动应用程序时，我都会收到以下错误:

Example 1:
2016-09-29 12:46:58.659879 AppTest[] NSToolbarItem (<NSToolbarItem: >) had to adjust the size of <NSPopUpButton: > from {130, 26} to the expected size of {132, 27}. Make sure that this toolbar item view has a valid frame/min/max size. This is an app bug, please do not file a bug against AppKit or NSToolbar! Break on _NSToolbarAdjustedBorderedControlSizeBreakpoint
Example 2:
2016-09-29 12:46:58.666074 AppTest[] NSToolbarItem (<NSToolbarItem: >) had to adjust the size of <NSButton: > from {60, 25} to the expected size of {62, 27}. Make sure that this toolbar item view has a valid frame/min/max size. This is an app bug, please do not file a bug against AppKit or NSToolbar! Break on _NSToolbarAdjustedBorderedControlSizeBreakpoint

我尝试在 StoryBoard 中尝试更改大小，但没有成功，当我四处搜索时，我发现有几个人在使用新操作系统时也遇到了这个问题，但没有有用的答案。

有人遇到同样的问题，有什么建议吗？

非常感谢，

马克

无法在界面生成器中解决此问题。然而，在 NSToolbarItem 的子类中重写 minSize 解决了这个问题。

- (NSSize)minSize
{
    if (floor(NSAppKitVersionNumber) >= NSAppKitVersionNumber10_12) {
        /* Overriding this getter seems to be the only solution for runtime error logs like: NSToolbarItem (<APMRegularToolbarItem: 0x60e000039460>) had to adjust the size of <NSButton: 0x60f0001acce0> from {40, 25} to the expected size of {42, 27}. Make sure that this toolbar item view has a valid frame/min/max size. This is an app bug, please do not file a bug against AppKit or NSToolbar! Break on _NSToolbarAdjustedBorderedControlSizeBreakpoint
         */
        return NSMakeSize(42, 27);
    }
    else {
        return [super minSize];
    }
}
