custum table cell

1)继承UITableViewCell

2）实现- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier

       _nameLabel = [[UILabel alloc] init];
       _nameLabel.textAlignment = UITextAlignmentLeft;
       _nameLabel.font = [UIFont boldSystemFontOfSize:14];
       _nameLabel.textColor = [UIColor colorWithRed:0.494f green:0.259f blue:0.047f alpha:1.0f];
       _nameLabel.backgroundColor = [UIColor clearColor];

 

      _iconImageView = [[UIImageView alloc] init];
      
       [self addSubview:_nameLabel];
       [self addSubview:_iconImageView];

3）实现- (void)layoutSubviews 

    CGRect contentRect = self.contentView.bounds;
    if (_iconImageView.image) {
        CGFloat iconOffsetY = floor((contentRect.size.height -  ICON_DIMENSION) / 2);
        _iconImageView.frame = CGRectMake(contentRect.origin.x + PADDING + GROUP_STYLE_PADDING ,iconOffsetY, ICON_DIMENSION, ICON_DIMENSION);
    } else {
        _iconImageView.frame = CGRectZero;
    }
   
    CGSize nameTextSize = [_nameLabel.text sizeWithFont:_nameLabel.font];
    if (_nameLabel.text) {
        CGFloat nameTextOffsetX = _iconImageView.frame.origin.x + _iconImageView.frame.size.width + PADDING;
        _nameLabel.frame = CGRectMake(nameTextOffsetX, 0, nameTextSize.width,contentRect.size.height);
    } else {
        _nameLabel.frame = CGRectZero;
    }

 高度设为contentRect.size.height，让其居中
