how to implement such function?
the steps are the following,
(1) press a button or something
(2) the screen separate two parts and show its content.
I am new on iOS programming, I don’t know what’s the function called, and seek some resources to learn. Thanks.
PS:
if I want to code by myself, what should I learning, for example, core animation or something?
JWFolders may be helpful in getting the stuff you need. Just like Tigeuro said Cocoa Controls is a really good resource.
Have fun with it, Objective-C is a fun language to tinker with.
