public class UIVisualEffectView extends UIView implements NSSecureCoding
Proper use of this class requires some assistance on your part. Namely:
• Avoid alpha values < 1 - By default, when a view is partially transparent, the system composites that view and all of its subviews in an offscreen render pass to get the correct translucency. However, UIVisualEffects require being composited as part of the content they are logically layered on top of to look correct. If alpha is less than 1 on the UIVisualEffectView or any of its superviews, many effects will look incorrect or won't show up at all. Setting the alpha on views placed inside the contentView is supported.
• Judicious masking - Masks have similar semantics to non-opaque views with regards to offscreen rendering. Masks applied to the UIVisualEffectView itself are forwarded to all internal views, including the contentView. You are free to apply a mask to just the contentView. The mask you provide to UIVisualEffectView will not be the view that actually performs the mask. UIKit will make copies of the view to apply to each subview. To reflect a size change to the mask, you must apply the change to the original mask view and reset it on the effect view. Applying a mask to a superview of a UIVisualEffectView (via setMaskView: or the layer's mask property) will cause the effect to fail.
• Correctly capturing snapshots - Many effects require support from the window that hosts the view. As such, attempting to take a snapshot of just the UIVisualEffectView will result in the snapshot not containing the effect at all or it appearing incorrectly. To properly snapshot a view hierarchy that contains a UIVisualEffectView, you must snapshot the entire UIWindow or UIScreen that contains it.

public UIVisualEffectView _appearance()
UIAppearanceNote for iOS7: On iOS7 the tintColor property has moved to UIView, and now has special inherited behavior described in UIView.h. This inherited behavior can conflict with the appearance proxy, and therefore tintColor is now disallowed with the appearance proxy.

In any given view hierarchy the outermost appearance proxy wins. Specificity (depth of the chain) is the tie-breaker.
In other words, the containment statement is treated as a partial ordering. Given a concrete ordering (actual subview hierarchy), we select the partial ordering that is the first unique match when reading the actual hierarchy from the window down.
