From TableView to DetailViewController - iphone

Question

i have a TableView with some Names.
And i want to show these Names on an other ViewController, but i don´t get it.
Here is my code:
AnguckenViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UIViewController *DetailViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"DetailViewController"];
AnguckenViewController *DetailKey = [self.originalsource objectAtIndex:[tableView indexPathForSelectedRow].row];
const char *cPlainKey = [DetailKey cStringUsingEncoding:NSASCIIStringEncoding];
NSString *plistPath;
NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES) objectAtIndex:0];
NSString *pszDetailValueString = [NSString stringWithFormat:#"%s",szSafeKey];
NSString *szDetailValue = [temp objectForKey:pszDetailValueString];
[DetailViewController setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
[self presentViewController:DetailViewController animated:YES completion:^(void){}];
}
DetailViewController.h
#import <UIKit/UIKit.h>
#interface DetailViewController : UIViewController {
IBOutlet UIButton *BackButton;
NSString *_pszKey;
NSString *_pszValue;
}
#property (nonatomic, retain) NSString *pszKey;
#property (nonatomic, retain) NSString *pszValue;
#property (retain, nonatomic) IBOutlet UILabel *keyLabel;
#property (retain, nonatomic) IBOutlet UILabel *valueLabel;
#end
DetailViewController.m
#implementation DetailViewController
#synthesize pszKey;
#synthesize pszValue;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
_keyLabel.text = _pszKey;
}

Answer 1

You need to set the pszKey property of the view controller, e.g. the DetailViewController, before you display it modally.
DetailViewController.pszKey = #"The value";
[DetailViewController setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal];
[self presentViewController:DetailViewController animated:YES completion:^(void){}];
And also in the viewDidLoad, it is good to use the getter of the properties instead of accessing the instance variables directly:
- (void)viewDidLoad
{
[super viewDidLoad];
self.keyLabel.text = self.pszKey;
}

So finally it works,
i changed the line:
UIViewController *DetailViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"DetailViewController"];
to:
DetailViewController *DetailViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"DetailViewController"];
Thanks
