iphone share view variables

You can put your widget class as a property on the Application Delegate.

@interface youAppDelegate : NSObject <UIApplicationDelegate> {
   Widget *myWidget;
}

@property (readonly) Widget *myWidget;

@end

Then, instantiate it on the message "applicationDidFinishLaunching" of your application's delegate.

Once you've done that, you can access myWidget from anywhere in the project like this:

youAppDelegate *ad = (youAppDelegate*)[UIApplication sharedApplication].delegate;
Widget *w = [ad myWidget];

That code can be perfectly compiled and executed at viewController1, viewController2 or even on the tabBarController.
