iOS App
Kelvin Zhu's Hello World program
It is pretty easy to build a single-view iphone/ipad application building view-based project using xcode. After building the project, we can add buttons, labels, text(for input or output) and even pictures onto the view using interface builder.
There are two basic kinds of objects, outlet and action, to realize all the functions for ipod application. Outlet is like variable while action like function. So, to store the input or output for an ipod application, we should use outlet while using action when to implement buttons. We can easily write some objective-c code and link the cotent to all items you've built in interface builder, through which, the objects shown in applications can be linked with the codes written.
