view name from array?

bluefire66 · 02-10-2010, 07:25 AM

Hi guys,
I just started with iPhone Development so don't be too hard on me.

So in my first view I have this:

in the .h:

Code:

NSArray *listOfDocs;

in the .m:

Code:

- (void)viewDidLoad {
	NSString *documentsDirectory = [NSHomeDirectory() 
					  stringByAppendingPathComponent:@"Documents"];
	
	NSError *error = nil;
	listOfDocs = [[NSFileManager defaultManager]
					 contentsOfDirectoryAtPath:documentsDirectory error:&error];
	
	self.navigationItem.title = @"Documents";
	self.navigationItem.rightBarButtonItem = self.editButtonItem;
	
	[super viewDidLoad];
}

That grabs the contents of the documents directory and puts them into an array.

Now I want to display the array in my navigation view... so I do this:

Code:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
	return[listOfDocs count];
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    
    static NSString *CellIdentifier = @"Cell";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
	
	// Configure the cell.
	NSString *cellValue =[listOfDocs objectAtIndex:indexPath.row];
	cell.textLabel.text = cellValue;
	
	[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];

    return cell;
}

So far that works! But now I want to load a new view and have the name of the view be the name of the item clicked on. So I try this:

Code:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

	EditViewController *editView = [[EditViewController alloc] initWithNibName:@"EditViewController" bundle:nil];
	[editView setTitle:[listOfDocs objectAtIndex:indexPath.row]];
	// editView.title = @"name";
	[self.navigationController pushViewController:editView animated:YES];
}

That crashes the app with a "EXC_BAD_ACCESS"
when I comment out

Code:

[editView setTitle:[listOfDocs objectAtIndex:indexPath.row]];

it runs fine, the name just does not change.

I'm not sure what I am doing wrong.. can someone help please?

Thanks

Hi,

I do not have a solution - but it seems that I have the same problem. May you can set a breakpoint on the point where the app is crashing (when you try to objectAtIndex:X) - If it is of type "NSCFString" then we have the same issue...

Do you have a property of "setTitle" in the .h of the new View? Did you made @synth...?

BR,

Stefan
