Remarks

The UIAppearance class is a proxy that is created on demand to style views of a particular class. The UIAppearance framework is supported either as a way of styling all instances of a particular class or by styling all instances of a particular class that are contained in specific hierarchy.

You can get the global proxy for a particular element by accessing the static Appearance property of that class.

To obtain the UIAppearance proxy for a particular class, you should invoke the AppearanceWhenContainedIn(Type[]) method. This method takes a variable list of T:System.Type objects and it represents the set of containers that must be present for the style to be applied. You can use this as the pattern used to apply the style to your elements.

The following classes expose both the Appearance property and the AppearanceWhenContainedIn(Type[]) method:

ABPeoplePickerNavigationController, ADBannerView, ARSCNView, ARSKView, AVRoutePickerView, BCChatButton, CAInterAppAudioSwitcherView, CAInterAppAudioTransportView, T:CarPlay.CPWindow, EKEventEditViewController, GKAchievementViewController, GKFriendRequestComposeViewController, GKLeaderboardViewController, GKTurnBasedMatchmakerViewController, GLKView, HKActivityRingView, HMCameraView, INUIAddVoiceShortcutButton, MFMailComposeViewController, MFMessageComposeViewController, MKAnnotationView, MKCircleView, MKCompassButton, MKMapView, MKMarkerAnnotationView, MKOverlayPathView, MKOverlayView, MKPinAnnotationView, MKPolygonView, MKPolylineView, MKScaleView, MKUserTrackingBarButtonItem, MKUserTrackingButton, MPVolumeView, MSStickerBrowserView, MSStickerView, MTKView, PdfThumbnailView, PdfView, PHLivePhotoView, PKAddPassButton, PKPaymentButton, RPSystemBroadcastPickerView, SCNView, SKView, UIActionSheet, UIActivityIndicatorView, UIAlertView, UIBarButtonItem, UIBarItem, UIButton, UICollectionReusableView, UICollectionView, UICollectionViewCell, UIControl, UIDatePicker, UIImageView, UIInputView, UILabel, UINavigationBar, UIPageControl, UIPickerView, UIPopoverBackgroundView, UIProgressView, UIRefreshControl, UIScrollView, UISearchBar, UISegmentedControl, UISlider, UIStackView, UIStepper, UISwitch, UITabBar, UITabBarItem, UITableView, UITableViewCell, UITableViewHeaderFooterView, UITextField, UITextView, UIToolbar, UIView, UIVisualEffectView, UIWebView, UIWindow and WKWebView.
