Question

How do you create a section of UITableView with numbers for each row like numbers 1, 2, 3 for each track in ‘Music’ app in iOS? Thanks in advance!

Answer 1

You can subclass UITableViewCell and create a subview UIlabel property, say..trackNumber and in your cellForRowAtIndex.. method you initialize your custom cell.

EDIT: Added example

   //CustomCell.h
@interface CustomCell : UITableViewCell

@property(nonatomic,retain) UILabel *trackNumber;

@end

//CustomCell.m
@implementation CustomCell
@synthesize trackNumber;

    - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
    {
        self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
        if (self) {
            // Initialization code
            self.trackNumber = [[[UILabel alloc] initWithFrame:CGRectMake(5,5,40,40)] autorelease];
            [self addSubview:self.trackNumber];
        }
        return self;
    }


    @end

To use it #import "CustomCell.h" and in your implementation.

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


CustomCell *cell = (CustomCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {

    cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

}

cell.trackNumber.text = [NSString stringWithFormat:@"%i",[indexPath row]];

// Configure the cell.
return cell;
}
