In an NSTabViewControllerwith a number of tabs, I didn't realize that by default when a tab is chosen, you are not given a new instance of the view. 有没有办法强制始终加载视图的新实例？

忽略为什么要这样做，您应该能够在该选项卡显示之前替换该选项卡的视图

  • 创建一个符合<NSTabViewDelegate>
  • 将其连接到选项卡视图的delegate插座
  • 实现-(void)tabView:(NSTabView *)tabView willSelectTabViewItem:(NSTabViewItem *)tabViewItem方法
