iphone - passing NSString from one class to the other

Question

I have a NSString that is taken from a UITextField in a ViewController. Every of my other ViewController will use this NSString as well. How can I pass this NSString to others ViewControllers?

Answer 1

You want to have a property in each of your controllers

@interface MyViewController : UIViewController{
    NSString *title;
}
@property (retain) NSString *title;
@end;


@implementation MyViewController
@synthesize title;
@end;

Use it like:

MyViewController *myVC = [[MyViewController alloc] initWithFrame:...];
myVC.title = @"hello world";
