What Is The Main Difference Between a View-Based Application Template And Window-Based Application Template In Iphone?
The core idea is that a Window-based application template is more bare-bones than a View-based one. Use a view-based application template for projects that have a single view. Use a window-based application template (or another template) for other types of projects.
View-Based Application Template has a UIView setup for you and Window-Based Application Template doesn't.
