Question

I am trying to assign a value to a string variable on a UITableViewController that I push on to my navigationController.

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
// now you can use cell.textLabel.text
NSMutableString *v = [[NSMutableString alloc] init];
[v setString:cell.textLabel.text];

DCAArtistViewController *dvController = [[DCAArtistViewController alloc] init];


if ([v isEqual:@"UK"]) {

    dvController.st =@"75";

}

[self.navigationController pushViewController:dvController animated:YES];

I have tried

[dvController.st setString:@"75"];

On the view that is loaded I have an NSLog which always shows null.

 NSLog(@"The st is%@",st);

What am I doing wrong? the examples I have seen show assigning to a property on a viewcontroller like this dvController.st =@”75″;

The DCAArtistViewController .h

#import <UIKit/UIKit.h>


@interface DCAArtistViewController : UITableViewController{

NSString *st;
NSMutableArray *aa;

}
@property (nonatomic, retain) NSMutableArray *listOfItemss;
@property (nonatomic, retain) NSString *st;
@property (nonatomic, retain) NSMutableArray *aa;

@end

This is the start of the DCAArtistViewController (The view that is loaded)

@implementation DCAArtistViewController
@synthesize listOfItemss;
@synthesize st;
@synthesize aa;

- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {

    aa = [[NSMutableArray alloc] init];
    NSLog(@"The st is%@",st);
    NSLog(@"The self st is%@",st);

The problem is simple. You are logging st in your init method. But you don’t set the st property until after the init method is called.
