How-To: Solve ‘modifying layer that is being finalized’ iPhone SDK

Okay, so I’ve been getting the ‘modifying layer that is being finalized’ error message when i’m trying to release a subview from a superview:
[self.popupPreviewView release]; self.popupPreviewView = nil;
The best way to solve this (that I’ve found – please post a comment if you can provide a better one) is to remove the view from it’s superview rather than release it:
[self.popupPreviewView removeFromSuperview]; self.popupPreviewView = nil;

The real issue in this case is rather the retain counter of popupPreviewView.
self.popupPreviewView = nil probably already does the release you need plus you need to remove the view from the superview because the superview retains the popupPreviewView.
a good practice is to avoid writing things such as [self.myproperty release]
