    text
    copied!<p>I am a noob at iOS application development.<br/> I trying to create "UITableView -> to Detail View" application.<br/> And found out "Master-Detail Application" project in the project template.</p> <p>Then I tried it out. Then the problem came. I had a dynamic table view, so I have to make the detail view look dynamic too. Like this :</p> <pre><code>Table View Detail View Item A Item A is an &lt;item_A_description&gt;, with &lt;item_A_summary&gt; Item B Item B is an &lt;item_B_description&gt;, with &lt;item_B_summary&gt; Item C Item C is an &lt;item_C_description&gt;, with &lt;item_C_summary&gt; </code></pre> <p>the problem is, after I go back to the table (list) view using back button menu, then I choose the again the item from different row of the list, then the Detail View doesn't changed to selected Item value.<br/> I did pass the value using (MasterView) -> initWithNibName -> (DetailView)<br/> My environment : XCode 4.2 for SnowLeopard, iOS SDK 5</p> <p><strong>Updated</strong><br/> After I check the log, the parameter value did passed with the correct value. But the IBOutlet of UIlabel that I set didn't change it's value.<br/> This is my code : </p> <p>MasterViewController.m:</p> <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { TheItems *a = [data objectAtIndex:[indexPath row]]; if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { if (!self.detailViewController) { self.detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController_iPhone" bundle:nil withItemId:(NSString *)a.itemId]; } [self.navigationController pushViewController:self.detailViewController animated:YES]; [self.detailViewController release]; } } </code></pre> <p>DetailViewController.h : </p> <pre><code>@interface metapsDetailViewController : UIViewController &lt;UISplitViewControllerDelegate&gt; { NSString *itemId; } @property (strong, nonatomic) IBOutlet UILabel * detailItem; @property (nonatomic, retain) NSString *itemId; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil withItemId:(NSString *)itemId; </code></pre> <p>DetailViewController.m :</p> <pre><code>@synthesize detailItem = _detailItem; @synthesize itemId; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil withItemId:(NSString *)itemId { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { self.title = NSLocalizedString(@"Detail", @"Detail"); self.itemId = itemId; } } - (void)viewDidLoad { self.detailItem.text = self.itemId; } </code></pre> <p>Thanks</p>
