It's really embarrassing but i stuck on it for two hours of trial and error.

I declared an NSString in the interface as:

NSString *testString;

Then i made a property and synthesized it. I allocate it in viewDidLoad with:

testString = [[NSString alloc] initWithFormat:@"thats my value: %i", row];

If i want to get the value of the string in another method it always return (null). So the string is empty, but why? how do i make it accessible for every function inside of one class? So i don't want to make a global var just a "global variable inside the class"

It's really confusing because as long as i code i never ran into this problem :(

thanks a lot for helping me!
