ios - 无法从 NSTextAttachment 创建 NSMutableAttributedString

Question

我正在尝试使用 NSMutableAttributedString 的初始化器:

NSMutableAttributedString(attachment: NSTextAttachment())

但我收到错误:

Argument labels '(attachment:)' does not match any available overloads.

Answer 1

您应该首先创建一个带有附件的NSAttributedString，然后从中初始化一个可变字符串:

let attrString = NSAttributedString(attachment: textAttachment)
let mutableAttrString = NSMutableAttributedString(attributedString: attrString)
