UIView Background Handling

Control	usesColorOnly	usesImage	NOTES
PXMKAnnotationContainerView	-	-
PXMKAnnotationView	-	setImage
PXMKMapView	-	-
PXMPVolumeView	-	-
PXUIActionSheet	backgroundColor = context.color	backgroundColor = [UIColor colorWithPatternImage: context.backgroundImage]
PXUIActivityIndicatorView	backgroundColor = context.color, layer.contents = nil	backgroundColor = [UIColor clearColor], layer.contents = context.backgroundImage
PXUIButton	backgroundColor = context.color OR backgroundImage = context.backgroundImage	backgroundImage = context.backgroundImage	Use background color on RoundedRect, normal state only
PXUICollectionView	backgroundView = nil, backgroundColor = context.color	backgroundColor = [UIColro clearColor], backgroundView = [UIImageView context.background]
PXUICollectionViewCell	!!! backgroundView, backgroundColor, selectedBackgroundView		Too complicated to capture here
PXUIDatePicker	-	-
PXUIImageView	(see note)	image = context.backgroundImage	If highlighted, simply sets highlightedImage = context.backgroundImage
PXUILabel	backgroundColor = context.color	backgroundColor = [UIColor colorWithPatternImage: context.backgroundImage]
PXUILayoutContainerView	-	-
PXUINavigationBar	barTintColor = context.color OR tintColor = context.color, backgroundImage = nil	backgroundColor = [UIColor clearColor], backgroundImage = context.backgroundImage	UsesImage uses barMetrics
PXUIPageControl	backgroundColor = context.color	backgroundColor = [UIColor clearColor], layer.contents = backgroundImage
PXUIPickerView	-	-
PXUIProgressView	trackTintColor = context.color, trackImage = nil	trackImage = inset(context.backgroundImage) OR trackImage = context.backgroundImage
PXUIRefreshControl	-	-
PXUIScrollView	backgroundColor = context.color, layer.contents = nil	backgroundColor = [UIColor clearColor], layer.contents = backgroundImage
PXUISearchBar	barTintColor = context.color OR tintColor = context.color	barTintColor = [UIColor colorWithPatternImage: context.backgroundImage] OR setTintColor
PXUISegmentedControl	tintColor = context.color	tintColor = nil, backgroundImage = context.backgroundImage	UsesImage uses barMetrics
PXUISlider	backgroundColor = context.color	backgroundColor = [UIColor colorWithPatternImage: context.backgroundImage]
PXUIStepper	tintColor = nil, backgroundImage = context.backgroundImage	tintColor = nil, backgroundImage = context.backgroundImage	iOS 6+ only
PXUISwitch	backgroundColor = context.color	layer.contents = context.backgroundImage
PXUITabBar	!!! barTintColor, backgroundImage	?	Some faulty logic in here
PXUITableView	backgroundView = nil, backgroundColor = context.color	backgroundColor = [UIColor clearColor], backgroundView = context.backgroundImage
PXUITableViewCell	!!! backgroundView, backgroundColor, objc_setAssociatedObject, selectedBackgroundView		Possibly the most complicated logic we have
PXUITableViewCellContentView	-	-
PXUITableViewHeaderFooterView	contentView.backgroundColor = context.color	contentView.backgroundColor = [UIColor colorWithPatternImage: context.backgroundImage]
PXUITextField	backgroundColor = context.color	backgroundColor = [UIColor colorWithPatternImage: context.backgroundImage]
PXUITextView	backgroundColor = context.color	layer.contents = context.backgroundImage
PXUIToolbar	barTintColor OR tintColor, backgroundImage = nil	backgroundColor = [UIColor clearColor], backgroundImage = [UIColor colorWithPatternImage: context.backgroundImage]
PXUIView	backgroundColor = context.color	backgroundColor = [UIColor colorWithPatternImage: context.backgroundImage]
PXUIWebView	-	-
UIBarButtonItem+PXStyling	backgroundImage = nil, tintColor = context.color	backgroundImage = context.backgroundImage
UITabBarItem+PXStyling	?	setImage = contextBackgroundImage OR setFinishSelectedImage = context.backgroundImage	Doesn't handle colorOnly case
