xcode – NSOpenPanel中缺少标题栏？

概述从OS X 10.11开始,即使使用setTitle,标题栏似乎也不再出现：有没有人知道发生了什么以及如何恢复旧行为？ 从 AppKit Release Notes for OS X v10.11： In 10.11, most NSOpenPanels have adopted a design that was formerly reserved only for applications w 从OS X 10.11开始,即使使用setTitle,标题栏似乎也不再出现：有没有人知道发生了什么以及如何恢复旧行为？解决方法 从 AppKit Release Notes for OS X v10.11：

In 10.11,most NSOpenPanels have adopted a design that was formerly reserved only for applications which adopted iCloud documents support and this panel design was only used if iCloud Drive was turned on in System Preferences. This note will refer to the design as the “iCloud Open Panel Design” although the design is no longer limited to applications with iCloud documents support.

iCloud Open Panel Design没有任何标题外观,因此它现在似乎已经消失.我认为没有办法回来.

如果要显示某种消息,描述或标题,可以使用message属性.
