Question

I know how to do for share data between 2 views. But if I want to share data using a tabBarController I’m lost.

This is my IBAction to move to my tabBar.

-(IBAction)goToPage2:(id)sender
{
 tabController.modalTransitionStyle=UIModalTransitionStyleFlipHorizontal;
 [self presentModalViewController:tabController animated:YES];
}

i need to share my NSString *dataStr in my IBAction in the first view of my tabBar.

firstView *first = [[firstView alloc] initWithNibName:@"firstView" bundle:nil];
first.dataStr = name.text;
[tabController  presentModalViewController:first animated:YES];

this code doesn’t work.

thx

Declare a @property in your app delegate. And you can access your app delegate from any point of your app.

MyAppDelegate *appDelegate =  (MyAppDelegate *)[[UIApplication sharedApplication ]delegate]
