比较两个NSStrings的相似性 [英] Compare similarity of two NSStrings

问题描述

我想比较两个 NSString 。如果用户键入Stonehhengge，应该得到一个border on answer=几乎等于，因为正确的答案是：Stonhenge。

I would like to compare two NSStrings. If the user types "Stonehhengge", should get a "border on answer"="almost equals", because the right answer is: "Stonhenge".

一个字符串等于另一个字符串的百分比。如果Stonhenge是9个字母，并且键入的文本包含Stonhenge的8个字母，但不等于Stonhenge，例如：Stonehange不等于Stonhenge，但它接近 -

I would like a percentage of how much one string equals another. If "Stonhenge" is 9 letters, and the typed text contain 8 letters from "Stonhenge", but it's not equal to "Stonhenge", for example: "Stonehange" is not equal to "Stonhenge", but it's near - I'd like to know how near a match the strings are.

我只知道 isEqual：。如果你输入巨石阵，你会匹配，并得到正确的符号。

I only know isEqual:. If you type "Stonehenge", you match and will get the right symbol. If text field's text is not equal, you do not get a match and get the wrong symbol.
