when you load view from Nib then it will alloc memory every time when cellForRowAtIndexPath called so it is better way to just redraw cell instead of alloc memory every time.
May below example will help you.

Parametrically crate label in custom cell. like

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
if ((self = [super initWithStyle:style reuseIdentifier:reuseIdentifier])) {
lblusername=[[UILabel alloc]initWithFrame:CGRectMake(70, 10, 150, 25)];
    lblusername.backgroundColor=[UIColor clearColor];
    lblusername.textColor=[UIColor colorWithRed:33.0/255.0 green:82.0/255.0 blue:87.0/255.0 alpha:1.0];
    [contentview addSubview:lblusername];
    [lblusername release];
 }
return self;
}

And call custom cell using below listed code.

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

static NSString *CellIdentifier = @"Cell";

LeaderboardCustomeCell *cell = (LeaderboardCustomeCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[LeaderboardCustomeCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.lblusername.text=@"Hello";
}
