ios - 从字符串中删除换行符

Question

我有这样一个字符串:

var aString = "This is a string \n\n This is the second line of the string\n\n"

在 textview 中看起来像这样:

This is a string 

This is the second line of the string


// 2 extra lines of unnecessary white space

但我希望它看起来像这样:

This is a string 
This is the second line of the string

我想从字符串末尾删除所有“\n”，并删除它重复的\n，这样中间就没有空格了。

理想情况下，我猜最终结果应该是这样的:

var aString = "This is a string \n This is the second line of the string"

您的代码的基本思想是将所有双/n 替换为单个/n。

var aString = "This is my string"
var newString = aString.replacingOccurrences(of: "\n\n", with: "\n")
