How to copy UITableViewCell label to UILabel in nextView? - ios

Question

I just want to copy UITableViewCell's label (which is a simple string) into nextView's UIlabel.
I tried creating a string property in the nextView and passing it the cell label,
but it doesn't work.
I'm getting nil in nextView,
why is that? Here is my didSelectRowAtIndexPath Method
in rootViewController.m
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *selLabel =[tempArray objectAtIndex:indexPath.row];
DetailViewController *detailViewCont=[[DetailViewController alloc]initWithNibName:#"DetailViewController" bundle:nil];
detailViewCont.selectedLabel=selLabel;
[self.navigationController pushViewController:detailViewCont animated:YES];
NSLog(#"selected Label %#",detailViewCont.selectedLabel);
}
Last NSlog statement returns the correct string here.
In nextViewController.m
-(void)viewDidLoad
{
[super viewDidLoad];
selectedLabel=[[NSString alloc]init];
UILabel *label1=[[UILabel alloc]init];
label1.frame=CGRectMake(5,5,310, 60);
label1.font=[UIFont fontWithName:#"Arial Black" size:20];
label1.text=selectedLabel;
NSLog(#"sellabel %#",selectedLabel);
[self.View addSubview:label1];
}
NSLog statement here returns null

Answer 1

Delete the following line from you viewDidLoad method:
selectedLabel=[[NSString alloc]init];
This is clearing the value you set from the other view controller.
And this line:
label1.text=selectedLabel;
should really be:
label1.text = self.selectedLabel;
You setup a property, use it.

Answer 2

Try setting the selLabel before the pushViewController statement like below,
detailViewCont.selectedLabel=selLabel;
[self.navigationController pushViewController:detailViewCont animated:YES];

Answer 3

Move your line detailViewCont.selectedLabel=selLabel; before the pushViewController call. Your presenting the viewcontroller before you assign the value.
#interface DetailViewController
...
#property (strong, nonatomic) NSString *selectedLabel;
#end
#implementation DetailViewController
#synthesize selectedLabel = _selectedLabel; // define the instance variable associated with the property
-(void)viewDidLoad {
label1.text = _selectedLabel;
}
#end
