Is this the correct way of refreshing the drawing in a different view?

Question

• Import the CustomView.h in the data controller header file
• Create an IBoutlet to my CustomView from there
• Connect that outlet instoryboard from the DataController to the CustomView
• Use that to call the view's setNeedsDisplay method.

Every time I add an item to the core data context I would like it to notify the CustomView (which lives in another tab) to redraw itself.

I am using ios5 and storyboards.

是的，DataController应该在需要刷新时通知视图，因为数据已更改，因此您的实现是合理的。
