Access textfield value from other class

Question

Hi guys,
I got a little newbie-problem to solve.
To say it simple I have the following code (2 classes):
@interface class1 : UIViewController {
IBOutlet UITextField *textField;
@property(nonatomic, retain) UITextField *textField;
@implementation
@synthesize textField;
@implementation class2
class1 *class = [[class1 alloc] init];
[[class textField] setText:@"text"];
My problem is, that the text will not show up in the textfield.
If I set the text in class1 everything works fine, but not when I try to set it from class2. The connections between the classes work well, because by using code completion it finds the textfield. I am not used to use property and synthesize, maybe thats the problem?
Thanks for help,
Krissi

I'm more familiar with Mac programming and have just started playing with the iPhone SDK so I'm still trying to get my head around how iPhone apps are structured. It's a little hard to give you a definite answer without knowing more about your "class2" and how your xib file(s) are set up and perhaps which template you used to create your iPhone app.
Assuming your xib file is named "class1.xib", it looks like the code you posted should load the xib. To check: set a breakpoint at that line, run in the debugger, once you stop at that line click the "Step over" button and see if the pointer value for your class1 variable gets updated.
When you run your app are you even seeing the view with the text field on the screen? It may be that you've loaded the xib but you need to add it to your window. Here's a code snippet from the "MoveMeAppDelegate.m" file in Apple's "MoveMe" sample code for iPhone. This is from the "applicationDidFinishLaunching" method where the delegate object is loading a xib file and adding it to the window:
UIViewController *aViewController = [[UIViewController alloc] initWithNibName:@"MoveMeView"
bundle:[NSBundle mainBundle]];
self.viewController = aViewController;
[aViewController release];
// Add the view controller's view as a subview of the window
UIView *controllersView = [viewController view];
[window addSubview:controllersView];
[window makeKeyAndVisible];
Hope this helps,
