@jingcheng1988 这个pr有问题吗？你们是否也遇到了size计算不对的问题

我这边review一下开源的代码，在main分支上提供轻量化的处理方案，你可以验证一下是否修复了你的问题

demo.zip
data:
{
"flowerDTO": {
"title": "送您1个小礼物",
"content": "感谢xxxxxxxxxxxx，很热情，主动帮我111111～",
"time": "08-11 16:40",
"customerNo": "xxxxxx",
"orderNo": "111111111",
"url": "查看全部"
}
}
并未修复这个问题，上面是我们的demo 你可以看一下 @jingcheng1988

根据你提供的模板和数据，我进行本地模拟，得出的结果如下：
视图创建：<GXRootView: 0x11b70a8f0; frame = (10 140; 370 169); clipsToBounds = YES; backgroundColor = UIExtendedSRGBColorSpace 0.247059 0.584314 0.631373 1; layer = <CALayer: 0x2806d50a0>>
size计算：NSSize: {370, 169}

创建的视图和实际计算出来的尺寸是一致的

我这边复现了一下，发现是一个临界case，最终的原因是由于 paraStyle.lineBreakMode = NSLineBreakByCharWrapping;
计算和creatview的最终是不一致导致的

// 生成AttributedString
NSMutableAttributedString *attrStr = nil;
if (attributeText) {
attrStr = [[NSMutableAttributedString alloc] initWithAttributedString:attributeText];
} else {
attrStr = [[NSMutableAttributedString alloc] initWithString:text];
}

//增加段落 & font属性
NSMutableParagraphStyle *paraStyle = [[NSMutableParagraphStyle alloc] init];
paraStyle.lineBreakMode = NSLineBreakByCharWrapping;
[attrStr addAttribute:NSParagraphStyleAttributeName value:paraStyle range:NSMakeRange(0, text.length)];
