This constructor is invoked by the runtime infrastructure () to create a new managed representation for a pointer to an unmanaged Objective-C object. You should not invoke this method directly, instead you should call the GetNSObject method as it will prevent two instances of a managed object to point to the same native object.

This constructor is used to programmatically create a new instance of UITextField with the specified dimension in the frame. The object will only be displayed once it has been added to a view hierarchy by calling AddSubview in a containing view.

This constructor is not invoked when deserializing objects from storyboards or XIB filesinstead the constructor that takes an NSCoder parameter is invoked.
