Html 不尊重父母的子女'；s码迅捷
我们目前正在为SwiftUI开发一个类似Twitter的客户端，我们必须将HTML内容转换为Html 不尊重父母的子女'；s码迅捷,html,ios,swift,swiftui,nsattributedstring,Html,Ios,Swift,Swiftui,Nsattributedstring,我们目前正在为SwiftUI开发一个类似Twitter的客户端，我们必须将HTML内容转换为NSAttributedStrings。出于这个原因，我们正在使用样式设置HTML标记。它似乎工作正常，但当我们试图显示内容时，文本只会覆盖其他内容。我们认为这是因为它不尊重它的父母的大小，但它可能是其他的东西 我们如何解决这个问题？有没有更好的方法在SwiftUI中呈现HTML内容，而不需要使用WKWebViews，因为这会导致难以置信的性能下降 我们有什么遗漏吗 提前谢谢 我们的代码： Netwo
