如何向 UITextView 添加图像/按钮?有自动换行功能吗?
我想将图像/按钮添加到我的 UITextView 中,文本应自动换行以适合图像/按钮。
第二个问题。我想制作一个名为“移动图像/按钮”的按钮,然后用户可以通过 UITextView 移动图像/按钮,并且文本应该调整
。
PS:就像 Mac 上的“Pages”或 Windows 上的“Word”
I want to add an image/button to my UITextView and the text should automatically make a line break that the image/button fits.
Second question. I want to make a button called "move image/button" and then the user can move the image/button through the UITextView and the text should adjust
.
PS: like in "Pages" for mac or "Word" for Windows

这绝对不是一件小事。对于初学者来说,你不能简单地将 UIImage 嵌入到 UITextView 中,即使你可以,文本也不会神奇地在它周围流动。您需要做的是基于 UITextView 创建自己的对象,该对象大大扩展了其功能以提供此类编辑工具。
要了解您要进入的内容,您可能需要查看 来自 Omni Group 的示例文本编辑器源代码。
This is decidedly non-trivial. For starters, you can't simply embed a UIImage inside a UITextView and even if you could text wouldn't magically flow around it. What you'll need to do is create your own object based on a UITextView that substantially extends its capabilities to provide such editing tools.
For a heads-up as to what you're getting into you might want to take a look at the example Text Editor source code from the Omni Group.
将
UITextView
的attributedText
属性与带有图像的NSAttributedString
和NSTextAttachment
结合使用。请注意,UITextView
必须是Selectable
(在 Storyboard 中)。Swift 演示:
attributedImage
是从这些方便的初始化程序构建的:此解决方案适用于:iOS 7.0、macOS 10.11、tvOS 9.0、*。
Use the
attributedText
property ofUITextView
with anNSAttributedString
withNSTextAttachment
with image. Note that theUITextView
must beSelectable
(in Storyboard).Swift demonstration:
Where the
attributedImage
is built from those convenience initializers:This solution works for: iOS 7.0, macOS 10.11, tvOS 9.0, *.
