如果在中使用多个标签，请使用低于286.0f的值（例如150.0f)

只需在UITableViewCell类中实现一个静态方法，该方法能够根据提供的字符串和宽度计算单元格高度。细胞应该知道它是如何构造的，它会占用多少空间。

例如:

+ (CGFloat)heightForWidth:(CGFloat)width text:(NSString *)text {

    CGFloat height = ... ;

    return height;
}

尝试禁用情节提要中的自动布局，然后调用SizetOfit。

cell.nameLabel.text = [NSString stringWithFormat:@"%@",self.name];
cell.nameLabel.numberOfLines = 0;
cell.nameLabel.lineBreakMode = NSLineBreakByWordWrapping;
[cell.nameLabel sizeToFit];
