I load a UIImageView
with an image depending on user interaction. When the parent view is initially displayed, no image has been selected and the imageview is black. If the user leaves that view and comes back, the image is still there. I've tried
myImageView.image = nil;
upon leaving the view but the image remains. How can I remove the image so the UIImageView
appears black again?
The
UIImageView
is connected through IB.
Setting the UIImageView
as:
myImageView.image = nil
is the correct way to clear an UIImageView
. Are you loading the image when your calling function returns? Is your UIImageView
being declared, and/or used elsewhere in your main function?
Try stating [self.imageView setNeedsDisplay];
after your image setting to nil. This will trigger a redraw of that element on the next runloop cycle I believe. Aka you are marking this view as 'dirty' and needs a redraw.
