You can change the window's windowLevel (via -setLevel:) to NSFloatingWindowLevel.
您可以将窗口的windowLevel（通过-setLevel :)更改为NSFloatingWindowLevel。
[window setLevel:NSFloatingWindowLevel];

By "on the top", do you mean you do not want your window to be obscured, even if a different app is active? In that case, one way is to start with the NSPanel template in Interface Builder, check the "Utility" option, and uncheck "Hide on Deactivate".
通过“在顶部”，您是否意味着您不希望您的窗口被遮挡，即使其他应用程序处于活动状态？在这种情况下，一种方法是从Interface Builder中的NSPanel模板开始，选中“Utility”选项，并取消选中“Hide on Deactivate”。
