Constructors

UITabBarItem()	Default constructor that initializes a new instance of this class with no parameters.
UITabBarItem(IntPtr)	A constructor used when creating managed representations of unmanaged objects; Called by the runtime.
UITabBarItem(NSCoder)	A constructor that initializes the object from the data stored in the unarchiver object.
UITabBarItem(NSObjectFlag)	Constructor to call on derived classes to skip initialization and merely allocate the object.
UITabBarItem(String, UIImage, nint)	Creates a UITabBarItem item that has the `title` and an `image` to display, and then returns the new UITabBarItem item.
UITabBarItem(String, UIImage, UIImage)	Creates a UITabBarItem item that has the `title` and images to display for selected and unselected states, and then returns the new UITabBarItem item.
UITabBarItem(UITabBarSystemItem, nint)	Creates a UITabBarItem item that contains a UITabBarSystemItem item and has the integer value of `tag`, and then returns the new UITabBarItem item.
