iOS: UITextView增加视图附件(ViewAttachment)特性, 其他优化.

New Version ヾ(@^▽^@)ノ 💥

特性:

ViewAttachment 支持将自定义视图添加到富文本中 并在UITextView中显示, 支持更改视图大小.

注意: 不要擅自修改自定义视图的center和transform属性.

优化:

附件垂直居中对齐 (应该是全网最准确的居中方案 😂不是无脑-4)

AttributedString.ViewAttachment: (Only supports iOS: UITextView)

textView.attributed.text = """

\(.view(xxxxView))

\(.view(xxxxView, .custom(size: .init(width: 200, height: 200))))

\(.view(xxxxView, .proposed(.center))).

"""
