Passing a UILabel value of UItableviewcell to another view in iPhone?

cutiepie · October 2012

I am a newbie to objective-C and got strucked at a particular point.I have to pass a UILabel value from tableviewcell to a label in Scrollview when accessoryButtonTappedForRowWithIndexPath action takes place .But the value is not passed ..I donno where Iam going wrong? I am writing this code :

ViewController1.h:
UILabel *name1;
@property(nonatomic,retain)IBOutlet UILabel *name1;

    ViewController1.m:
- (void) tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{

ViewController2 *v2 = [[ViewController2 alloc] initWithNibName:@"ViewController2" bundle:nil];
v2.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;

[self presentModalViewController:v2 animated:YES];
 v2.provName=[name1 retain];   //name1 is the name of UILabel in TableView.
[v2 release];
}
    ViewController2.h
UILabel *providerName;
SString *provName;

    ViewController2.m:
- (void)viewDidLoad
{
providerName =[[UILabel alloc] init];
[providerName setFrame:CGRectMake(10,10,300,50) ];
providerName.textAlignment=UITextAlignmentLeft;
providerName.backgroundColor=[UIColor blackColor];

self.providerName.text=self.provName; 
 providerName.highlightedTextColor=[UIColor whiteColor];
[self.view addSubview:providerName];
}

I can see the label but not the value in it ...Y is it so?How to pass a UIlabel value to another view ?

That's very bad. Don't pass views between view controllers, pass the data instead.

Looking by the second half of the code it looks like you're trying to do that, but in vc2 provName is a strting (NSString, you have a typo), but you're passing the name1 from vc1 which is a UILabel. You also shouldn't be retaining there. Try this instead

v2.provName = [name1 text];

I couldn't get the value of UIlabel value getting passed.I tried v2.provName = [name1 text];

Do that before calling presentModalViewController.

Howdy, Stranger!
