I have a UIView that updates based on data in a certain object.
I’d like to be able to add a refresh button to my toolbar that reloads the object and redraws the view. I don’t want it to happen every time so don’t want to use viewWillAppear:
Sounds like it should be a popular thing to do but I can’t seem to find any answers on here or the web.
Thanks in advance.
If your underlying data has changed and the view needs to be redrawn to reflect this, send the view
-setNeedsDisplay, or-setNeedsDisplayInRect:if you only need to update a part of the view.
