pass information from one object to another(additional info)

I have a one view called iFetch104ViewController which contains a textField and a button.

with a click of this button .. I push a navigation bar view controller called ResponceViewController as follows.

[[self navigationController] pushViewController:[[ResponceViewController alloc] init] animated:YES];

instead of the above code, I wanted to pass the content of the text field also to the new navigation controller. and I tried the following:


ResponceViewController *test = [[ResponceViewController alloc]init];

test.testStr = numberField.text;
//numberField is a text field on the iFetch104ViewController
//testStr is a NSString pointer defined in ResponceViewController

[[self navigationController] pushViewController: test animated:YES];


so the program crashes every when it execute:

test.testStr = numberField.text;

pls help.........

Do you have accessor methods for testStr defined in ResponceViewController?

 

[henktade]

missing accessor methods

Do you have accessor methods for testStr defined in ResponceViewController?

that was exactly my problem. I come back to let u guys that I found the problem but tank you dejo for the replay.

I missed
@synthesize testStr;

in ResponceViewController.m

I am also having same problem.

I am having a variable storyLink in Rootviewcontroller class.
I want the result of storyLink in Testviewcontroller class.

So i use the below code,
Rootviewcontroller *rootviewcontroller1 = [[Rootviewcontroller alloc]init];
Testviewcontroller *testviewcontroller1 = [[Testviewcontroller alloc]init];
testviewcontroller1.test=rootviewcontroller1.storyLink;
//test is a string variable of Testviewcontroller


NSLog(@"Test View Controller link: %@",test);

In test i got null value.
Can you please tell me the solution?

I do. You need to give storyLink a value before you reference it.

Like so:
Rootviewcontroller *rootviewcontroller1 = [[Rootviewcontroller alloc]init];
rootviewcontroller1.storyLink = @"a non-nil value";
Testviewcontroller *testviewcontroller1 = [[Testviewcontroller alloc]init];
testviewcontroller1.test=rootviewcontroller1.storyLink;

Would you mind explaining how you solved it? In case others have the same issue, they can learn from your approach.
