I should have a main windows with a button (infoButton). In this
windows I should load a first view( it should be map view ) below the
infoButton. Push infobutton change view.
So a rootViewController is linked to man windows. In
rootViewController I would load map view like first view and I so I
MapView* mapView = [[[MapView alloc] initWithFrame: [[UIScreen
mainScreen] applicationFrame]] autorelease];
[self.view insertSubview:map belowSubview:infoButton]
but it crached when runs [[[MapView alloc...ecc.
Since I am new of obejective C and i-phone, I would know if I can use
MapView with Interface Builder.
