Hi. I'm a very newbie iphone and cocoa developer coming from j2ee
world. I'm creating an application with four screens using a TabBar.
The fourth view has a button wich uses UITextfields values from all
the views to calculate something ans show the result in a UITextfield
in the fourth view. This is my App Delegate:
@interface MyAppDelegate : NSObject <UIApplicationDelegate,
UITabBarControllerDelegate> {
UIWindow *window;
UITabBarController *tabBarController;
UIViewController *firstViewController;
UIViewController *secondViewController;
UIViewController *thirdViewController;
UIViewController *fourthViewController;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController
*tabBarController;
@property (nonatomic, retain) IBOutlet UIViewController
*firstViewController;
@property (nonatomic, retain) IBOutlet UIViewController
*secondViewController;
@property (nonatomic, retain) IBOutlet UIViewController
*thirdViewController;
@property (nonatomic, retain) IBOutlet UIViewController
*fourthViewController;
@end
I have my own controller classes for each view. The problem is that my
IBAction method that receives button event is in fourthViewController,
so I can't acces fields in the other views to get the values I need.
So, which is the usual way to do this? Maybe, adding the button action
receiver in MyAppDelegate?
