Create instance of view controller / trigger didSelectRowAtIndexPath

[svenJ]

What I'm working on
I'm working on a news app. A tableview with news items and more information when you click an item.

What I've done
Parse an online XML document. Display images + title from XML document and put it in a Table View. Works fine here. I also created a .h and .m file for the detailed news view. It contains a larger image and text, all dummy and placeholders.

Where I need your help
I need to connect each newsitem with this detailed view. I'm kinda stuck here.. I've tested my code as far as seeing weather I have all the data I need:

NSString *testString = [blogEntries objectAtIndex:indexPath.row];
NSString *msg = [[NSString alloc] initWithFormat:@"Current item selected: %@", testString];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Test item" message:msg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];  

[alert show];     
[alert release];
[testString release];
[msg release];

The code above works fine. It displayed the complete node from my XML document. What I want is an instance from newsDetailView.h / newsDetailsView.m and fill it up with the information from the current selected item. And slide it in from the right of the screen.

The code below works but, needless to say, it doesn't fill the dummy text and placeholders with the actual values. How do I do that?

nieuwsDetailView *NieuwsDetailView = [[nieuwsDetailView alloc] initWithNibName:@"NieuwsDetailView" bundle:nil];
[self.navigationController pushViewController:NieuwsDetailView animated:YES];
[NieuwsDetailView release];

Thanks in advance, I really appreciate any help!

You need to make a property in your NieuwsDetailView (most likely NSString) in which you will set the text you want after you alloc/init it. Then in the controller's (NieuwsDetailView) viewDidLoad method you can grab that value and display it where you want.

Thank you for your reply. The problem is; I don't know how to do that.. Do you have an example code or know where to got it maybe?

edit:
Also, the following code:

nieuwsDetailView *NieuwsDetailView = [[nieuwsDetailView alloc] initWithNibName:@"NieuwsDetailView" bundle:nil];
[self.navigationController pushViewController:NieuwsDetailView animated:YES];
[NieuwsDetailView release];

may be complete different. I think it doesn't need to push an view initiated with an Nib because, well I have a nib file, but I've created it completely programmatically. My NIB file is empty.

(As you might have guessed I'm kinda new and still struggling putting the pieces together)

Do this…

nieuwsDetailView.h
@interface nieuwsDetailView: UIViewController

@property(retain, nonatomic) NSString* theTestString;


theTableViewController.m

/* if a nib file */
nieuwsDetailView *NieuwsDetailView = [[nieuwsDetailView alloc] initWithNibName:@"NieuwsDetailView" bundle:nil];

/* pass the testString value to theTestString property in the detail view */
NieuwsDetailView.theTestString = testString;

[self.navigationController pushViewController:NieuwsDetailView animated:YES];
[NieuwsDetailView release];

Thanks a lot! Works great! :-)

I'm pretty much stuck again..

I successfully created the detailedNewsView. And I've also added a Next/Prev button at the top-right such as in Apple's mail app. But again I'm not quite sure how to get the right information passed through.

Sure I can add more variables (per the next and previous item) when a user tabs an item in the UITableView but if he or she then proceeds clicking 'previous' it will eventually get an error. Also I don't think this it THE way.

What is the most obvious way to do this? Send data from the UITableView or recollect information from the RSS Feed (I'm using TouchXML) for the previous and next item?

Once again thanks in advance!
