I’ve been banging my head with this issue for the last two days. Googled a lot but wasn’t able to find the answer yet, so I decided to request some help here. Let’s see if I get any luck.
I’m coding a reusable control that consists of an UIView with a variable number of customized UIButtons. I implemented initWithFrame:, initWithCoder: and drawRect: where the buttons (which are built prior to drawing) are actually added to the view. Everything is done programmatically since the UIButton content should be supplied when using the control, so there’s no XIB for this UIView.
This UIView, let’s call it CustomizableBarButton is then used in an UIViewController, let’s call it MyTestViewController with a view on it, let’s call it customizableBarButtonView.
MyTestViewController‘s GUI was set on IB where an UIView was tied to customizableBarButtonView (the class was matching accordingly).
MyTestViewController‘s is a pretty standard class except for the viewWillAppear: that initializes the buttons and passes them to the CustomizableBarButton along with some other options.
The issue is that everything works perfectly…except for the first time!
I mean, when I run the app on the simulator (I haven’t tried it on the iPhone yet but I strongly believe that it’s not an hardware issue) the MyTestViewController shows the customizableBarButtonView background but not the buttons. Now when you click on the place where a button should be all the buttons suddenly appear!
I’m puzzled since the CustomizablebarButton drawRect: runs before the strange “click n’appear” effect and the buttons are actually added to the subview.
Another hint that my help: if you don’t click on the buttons (so you still got no buttons yet) but rotate the device they will also appear as if by magic!
It is probably something very simple but I’m missing it and I’m going nuts…
Can someone lend a hand on this, please?
Thanks in advance!
You said you’re adding the buttons in
drawRect:. Don’t do that. You need to add the buttons in your init methods.
