UITextView使用 sizeWithFont:constrainedToSize:lineBreakMode:计算自适应文本高度
-(CGSize)dynamicHeightForTextViewWithFont:(UIFont*)s_font ConstrainSize:(CGSize)s_size{
//UItextView 会有一个padding,为8

CGSize adapter_size = CGSizeMake(s_size.width - 16, s_size.height); // 宽度减去padding,8*2 = 16
CGSize txtContentSize = [self sizeWithFont:s_font constrainedToSize:adapter_size lineBreakMode:UILineBreakModeWordWrap ];
txtContentSize.height += 16; //高度增加8*2 = 16
return txtContentSize;
