1,135 PointsPassing Data
no data was passed between my UIViewController called (DOG.h , DOG.M) and UITableView.. ANY idea guys why this is happening , Amit Bijlani
//DOG.h
@property(nonatomic,strong) NSString *stringdata;
@property (nonatomic,strong) IBOulet UILabel *dogname;
// DOG.m
@synthesize stringdata;
@synthesize dogname;
-(void)viewDidLoad{
dogname.text=stringdata;
[super viewDidLoad];
}
The tableview contain a list of dog types, to pass data I used the segue "showdogsegue"
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:@"showdogsegue"])
{
NSIndexPath *indexPath=[self.tableView indexPathForSelectedRow];
DOG *destviewcontroller=segue.destinationViewController;
PFObject *object=[self.typeDog objectAtIndex:indexPath.row ];
//typeDog is an NSArray
Dog*details=[[Details_User alloc]init];
details.stringdata=[object objectForKey:@"username"];
}
}

42,016 Pointsyou need to set the property of the destination view controller, not allocate a new one. you also need to cast segue.destinationViewController to DOG
NSIndexPath *indexPath=[self.tableView indexPathForSelectedRow];
DOG *destviewcontroller= (DOG *) segue.destinationViewController;
PFObject *object=[self.typeDog objectAtIndex:indexPath.row ];
//typeDog is an NSArray
destviewcontroller.stringdata=[object objectForKey:@"username"];
