Do Something like dis...!!!

NSString * titleString=pod.title;
    CGSize constraint = CGSizeMake(200,999);
    CGSize size = [titleString sizeWithFont:[UIFont systemFontOfSize:16] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

    titleLabel=[[[UILabel alloc] initWithFrame:CGRectMake(120, 24, 200, size.height)] autorelease];
    [titleLabel setText:titleString];
    [titleLabel setTextColor:[UIColor whiteColor]];
    [titleLabel setNumberOfLines:0];
    titleLabel.lineBreakMode=UILineBreakModeWordWrap;
    [titleLabel setFont:[UIFont systemFontOfSize:14]];
    [titleLabel setBackgroundColor:[UIColor clearColor]];
    [titleLabel setTextAlignment:UITextAlignmentCenter];
    [scrollView addSubview:titleLabel];
