Reading plist into TableView

Question

I started this project with a simple plist of a dictionary with two arrays of strings. I now want to add more information and want to use this plist structure:

R         


        

Answer 1

So providing you have your Standard - Array stored against a Array you've defined in your .h file then something like this would work. In this example the array is stored against self.coloursArray.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *SectionsTableIdentifier = @"SectionsTableIdentifier";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SectionsTableIdentifier];

if(cell == nil){
    cell=[[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SectionsTableIdentifier] autorelease];
    }
NSString* ColourString = [[self.coloursArray objectAtIndex:indexPath.row] valueForKey:@"Colour"];
NSString* rValue = [[self.coloursArray objectAtIndex:indexPath.row] valueForKey:@"Rvalue"];
NSString* gValue = [[self.coloursArray objectAtIndex:indexPath.row] valueForKey:@"Gvalue"];
NSString* bValue = [[self.coloursArray objectAtIndex:indexPath.row] valueForKey:@"Bvalue"];
cell.textLabel.text = ColourString;
NSString* subCellString = [NSString stringWithFormat:@"%@:%@:%@", rValue, gValue, bValue];
}

Hopefully that'll give a a hand.

First, do not use -[UITableViewCell initWithFrame:reuseIdentifier:]. It has been deprecated and will give you a warning, plus it will make your subtitle harder to implement. This code is a modified version of yours which loads the information, sets the title to the Color property, and sets the subtitle to a string containing the Rvalue, Gvalue, and Bvalue properties.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    NSUInteger section = [indexPath section];
    NSUInteger row = [indexPath row];
    NSString *key = [keys objectAtIndex:section];
    NSArray *colorSection = [colors objectForKey:key];

    static NSString *SectionsTableIdentifier = @"SectionsTableIdentifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SectionsTableIdentifier];

    if(cell == nil) {
        cell=[[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier: SectionsTableIdentifier] autorelease];
    }

    NSDictionary *color = [colorSection objectAtIndex:row];
    cell.textLabel.text = [color objectForKey:@"Color"];
    cell.detailTextLabel.text = [NSString stringWithFormat:@"%@, %@, %@",[color objectForKey:@"Rvalue"],[color objectForKey:@"Gvalue"],[color objectForKey:@"Bvalue"]];
    [cell setAccessoryType:UITableViewCellAccessoryDetailDisclosureButton]; //add disclosure button to rows
    return cell;
}
