有什么方法可以替换Swift String上的字符吗？ 15个答案

I want to replace some text in a string with another string.

我想用另一个字符串替换字符串中的一些文本。

For example : A string equals to "Red small car". I want to replace "small" with "big" so the string becomes "Red big car". I have to do this in swift. Thanks.

例如：一个字符串等于“Red small car”。我想用“大”代替“小”，所以字符串变成“红色大车”。我必须迅速做到这一点。谢谢。

You can try using stringByReplacingOccurrencesOfString

let string = "Big red car"
let replaced = (string as NSString).stringByReplacingOccurrencesOfString("Big", withString: "Small")
