问题描述
我需要获得NSSearchField的外观
I need to get this appearance of NSSearchField
但是用Interface Builder的标准方法设置backgroundColor似乎是不可能的.我怎样才能做到这一点?子类化NSSearchField和NSSearchFieldCell并没有帮助，因为在实现自己的draw方法时，我松开了所有动画(当您单击搜索字段并且icon + text向左滑动时).
But it seems to be impossible to set backgroundColor with standard methods of Interface Builder. How i can achieve this?Subclassing NSSearchField and NSSearchFieldCell didn't help, because i loose all animations (when you click on search field and icon+text sliding to left) when implementing my own draw methods.
推荐答案
当置于 NSVisualEffectView 下时，您的屏幕快照显示的只是 NSSearchField 的标准外观.也就是说，当它是 NSVisualEffectView (带有 NSVisualEffectMaterialLight 的 material )的子视图时，搜索字段将自动获得上方的外观.
What your screenshot shows is just the standard look of NSSearchField when being placed under an NSVisualEffectView. That is, the search field will automatically get the look above when it's a subview of NSVisualEffectView (with the material of NSVisualEffectMaterialLight).
但是，如果您希望这种外观没有 NSVisualEffectView ，则可以手动设置其外观:
However, if you want this appearance without NSVisualEffectView, you can manually set its appearance:
searchField.appearance = [NSAppearance appearanceNamed:NSAppearanceNameVibrantLight];
