iOS - passing data to pushed viewcontroller

Question

When pushing a viewcontroller, how do I pass data long with it as well (such as "asdf":123)? Are you supposed to addObjects to a NSBundle?

Answer 1

MyViewController * myVC = [[MyViewController alloc] initWithNibName:nil bundle:nil];
myVC.someProperty = someValue;    // Pass your data here
[self.navigationController pushViewController:myVC animated:YES];

And in your MyViewController class :

.h

@interface MyViewController : UIViewController
@property (nonatomic, strong) NSString * someProperty;
@end

.m

@implementation MyViewController

    - (void)viewDidLoad {
        [super viewDidLoad];
        // your data has been set
        // self.someProperty is equal to "some value"
    }

Answer 2

I don't believe you can, but of course you can add relevant properties or methods to your ViewController class and use these prior to pushing it.
