检查两个NSStrings是否相似 [英] Check if two NSStrings are similar
问题描述
我提出了一个棘手的问题，我不知道如何接近。所以，我制定了一个包含字典的plist，其中包含两个对象：
I present a tricky question that I am not sure how to approach. So, I have formulated a plist containing dictionaries which contain two objects:
- 国家名称
- 国家/地区的插头大小
虽然只有210个国家/地区。
There are only 210 countries/facts though.
而且，我已经搜索了许多国家的列表，其中可能有事实或不。但是这里是我的问题，我使用一个名为Geonames的Web服务，用户可以使用搜索栏显示控制器搜索国家，这些plist国家名称与插头大小配对实际上是从维基百科的文章。
And, I have enabled to search through a list of many many countries, in which there might be a fact or not. But here is my problem, I am using a web service called Geonames and the user can use a search bar display controller to search for countries, and these plist country names paired with plug sizes are actually from a Wikipedia article.
现在，Geonames和维基百科的plist中的国家命名可能会略有不同，可能有额外的空格，额外的破折号，额外的字母。这是为什么我想看看geoname国家字符串是否与plist中的字符串非常相似。
Now, the country naming in Geonames and in my plist from Wikipedia might be named slightly different, maybe with an extra space, an extra dash, an extra letter. This is why I want to see if the geoname country string is very similar to the one in the plist.
因此，这不会是 isEqualToString ：因为它发现是否确切，比较：方法是否有效？
So, this would not be isEqualToString: because that finds if it is exact, can the compare: method work?
我该如何处理？下面是一个例子：
How can I approach this? Here is an example:
Geoname返回（不是一个真正的国家只是一个例子）：
Geoname returns (not a real country just an example):
- Yiting
但plist可能会传回：
But plist may return:
- Yitting
有1个额外的't'，但还有其他情况。我希望这些比较确切，或至少相似，所以我可以认为他们作为一个匹配。
So with 1 extra 't', but there are other circumstances. I would like these to be compared as exact, or at least similar, so I could consider them as a match.
有没有任何教程，资源，项目等你可以指点我？
Are there any tutorials, resources, projects etc. you could point me towards?
谢谢！ Bye！
推荐答案
Soundex 算法在这种情况下很有用。
The Soundex algorithm is useful in cases like this.
我发现了一个示例实现在github上。
I found a sample implementation on github.
