Question about chapter 7 tableview

dave1964 · February 20th, 2011, 10:16 AM

I did the example for chapter 7 and it worked like the example. But I realized that I wanted to show the movie name in the Title, not "Item 1" which is what I am seeing now with
navigationBar.topItem.title = [detailItem description];

and It would be even better to print the year, is there any easy way of accessing the array name?

To get the title displayed in the detailview replace in
RootViewController.m

Code:

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

detailViewController.detailItem = [NSString stringWithFormat:@"Row %d", indexPath.row];
with
detailViewController.detailItem = [[[aTableView cellForRowAtIndexPath:indexPath] textLabel] text];

See if you can work out displaying the year. If not, I'll post it later.

Thanks that was exactly what I was looking for.

For the year I added a new ID value, called detailYear and set it as follows.

detailViewController.detailYear = [sectionTitle objectAtIndex:[indexPath section]];

the odd thing is I seem to be getting the year of the previously selected item.

In RootViewController.m

Code:

- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {	NSString *theTitle = [[[aTableView cellForRowAtIndexPath:indexPath] textLabel] text];
	NSString *theYear;
	if (isSearchOn) {
		theYear = @"";
	}else {
		theYear = [years objectAtIndex:[indexPath section]];
	}
	detailViewController.detailItem = [NSString stringWithFormat:@"%@ %@",theTitle, theYear];
}

Will display the title and the year, if a search is not being done.

For what it is worth, the following will display the title and date in the detailView when selected, whether search is on or off

Code:

- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    
	NSString *theTitle = [[[aTableView cellForRowAtIndexPath:indexPath] textLabel] text];
	NSString *theYear;

	for (NSString *yearKey in movieTitles) {
		for (NSString *aTitle in [movieTitles valueForKey:yearKey]) {
			if ([aTitle isEqualToString:theTitle]) {
				theYear = yearKey;
			}
		}
	}
	detailViewController.detailItem = [NSString stringWithFormat:@"%@ %@",theTitle, theYear];
}
