没有'|'候选人产生预期的上下文结果类型'NSTextStorageEditActions' [英] No '|' candidates produce the expected contextual result type 'NSTextStorageEditActions'

问题描述

我在文本工具包教程 http://raywenderlich.com =noreferrer> raywenderlich.com 和行

I went through the Text Kit Tutorial on raywenderlich.com and the line

edited(.EditedCharacters | .EditedAttributes, range: range, changeInLength: (str as NSString).length - range.length)

产生以下错误：

No '|' candidates produce the expected contextual result type 'NSTextStorageEditActions'

当我将第一个参数更改为：

The error goes away when I change the first argument to:

edited(.EditedCharacters, range: range, changeInLength: (str as NSString).length - range.length)

我也试过用OR和||没有任何成功。

I also tried using "OR" and "||" without any success.

Swift 2.2和iOS 9.2

推荐答案

@ dfri是对的。为了说明使用管道的另一个例子，|是在为UIImageView执行autoResizingMask时，如下所示：

@dfri is correct. To illustrate another example of using the pipe, "|", is when doing the autoResizingMask for UIImageView as follows:

imageView.autoresizingMask = [。 FlexibleWidth，.FlexibleHeight，...]

当然你要替换 ...... 使用其他 UIViewAutoresizing 选项。

Of course you'd replace the ... with other UIViewAutoresizing options.

祝你好运！
