Problem setText UITextView

Question

Hi i have a problem. I have 2 viewcontroller, in the first there is a mapView that implements the function "calloutAccessoryControlTapped" to tap a button on an annotation on the mapView; in the second there is just a UITextView. I want to change the text of the UITextView (and show the SecondViewController) in the second controller once the button on annotation is clicked; here is my code

(FirstViewController)

Header

@interface FirstViewController<MKMapViewDelegate>{ 
IBOutlet MKMapView *mapView;
SecondViewController *secondV;}
@end

Implementation

@implementation FirstViewController

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control{
secondV = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
NSString *myS = @"some text here";
[secondV.myTextView setText:myS];

//Switch from this to the secondview [self presentModalViewController:secondV animated:YES]; @end

(SecondViewController)

Header

@interface SecondViewController{ 
IBOutlet UITextView *myTextView;
}

@property(nonatomic, retain)UITextView *postitTextView;
- (IBAction)backToMAp;
- (void)setText:(NSString *)string;
@end

Implementation

@implementation SecondViewController

- (IBAction)backToMAp{

//Back To First View; [self dismissModalViewControllerAnimated:YES];}

- (void)setText:(NSString *)string{ 
myTextView.text = string;}

In this code when i tap on the button ([self presentModalViewController:secondV animated:YES];) on annotation the first time the second view show up but the text of UITextView don't change, when i back on the FirstView ([self dismissModalViewControllerAnimated:YES];) and then again tap the button to switch again to secondView the text of UITextView change.....

Sorry for long thread and for my bad english!!

Thank you stack!

Answer 1

I forget to set myTextView as @property:

@property(nonatomic, retain)UITextView *myTextView;

and i forget to insert the @syntesize in the implementation:

@syntesize myTextView;

You have two UITextViews in your code: myTextView and postitTextView. In IB have you got the right one in the your UIView?
