Useful third-party object-C GUIs for iPhone development

Question

When I develop in .NET, there are many user interface controls from companies such as Infragistics and Telerik that allow me to quickly and quickly create super-standard amenities and stylish graphical interfaces. Is there something similar for developing iPhone Objective-C?
