how to fix the height of a tableview cell

Question

Recently I have written a custom UITableViewCell with a height of 60.0f. When it runs on different device, such as iPhone5 iPhone6 iPhone6 + , the height and fontSize changes automatically. How to fix the height?

  - (id)initWithStyle:(UITableViewCellStyle)style
        reuseIdentifier:(NSString *)reuseIdentifier
    {
        self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
        if (!self) {
            return nil;
        }       
        self.textLabel.adjustsFontSizeToFitWidth = NO;
        self.textLabel.font = [UIFont systemFontOfSize:15.0f];
        self.detailTextLabel.adjustsFontSizeToFitWidth = NO;
        self.detailTextLabel.font = [UIFont systemFontOfSize:12.0f];
        self.detailTextLabel.numberOfLines = 0;
        _switchButton = [[UISwitch alloc] initWithFrame:CGRectMake(250, 9, 30, 20)];
        _switchButton.tag = 400;
        [_switchButton addTarget:self action:@selector(switchAction:) forControlEvents:UIControlEventTouchUpInside];
        [self addSubview:_switchButton];

        _button = [UIButton buttonWithType:UIButtonTypeCustom];
        _button.frame = CGRectMake(250, 9, 60, 30);
        [_button addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
        [self addSubview:_button];
        _button.backgroundColor = [UIColor clearColor];

        return self;
    }

in the controller:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 60.0;
}

将self.detailTextLabel.numberOfLines设置为精确值，而不是0。这将关闭标签的自动大小调整。
