Hello all.
Well after reading the docs, and some examples form books, I came up
and tried to build a "prototype" of what I want. So I needed to load a
initial view with 2 buttons, one will lead me to InfoViewController
and the other one to an AuthenticationViewController, each one has its
related .xib, from the AppViewcontroller, I can have 2 instances of
each viewController, and then if I put a button in the appController
view I can swap the views, but the button will have to remain (in a
toolbar, or something similar). What I want is to load
InfoViewController's view when app loads, with will be at the
viewDidload form the AppViewController, and InfroViewController's
view should have its design, but also a button to go back to the Main
view, which is the one in AppviewController's view. Also from the
AuthenticationViewController's view
So I had that in mind, but when I came up to implemented I had a
problem, the IBAction for those buttons I will place them in their
respective view controllers (InfoViewController and
AuthenticationviewController), but they know nothing about the
AppViewController who is (was)the one in charge of swapping the views...
Should I ask for the AppViewController instance (view singleton
patern) and send the aodl and new view to be placed? ( I did something
like this , not to change views, but displaying things in a cocoa
app), but I dunno if these same idea can be applied in a iPhone app,
or is there a better workaround.
Thanks
