如何在UITextView或字符串中查找重复或相同单词的范围? [英] How to find the range of duplicate or same words in UITextView or from string?

问题描述

我正在努力在textview中查找任何单词的正词，在这里我需要找到单词首先说成的范围

I was working to find the rect of any word in textview ,where I need to find the range of the word first say as

NSRange textRange=[textview.text rangeofString:@"sabby"];

现在我在文本视图中说了三遍，现在我需要获取第二个的范围 不好意思的单词不是第一个...那么我该怎么做... 换句话来说，也是一样. 因为如果我使用上面的代码行，它将给我第一个到来的单词的范围 文本视图...

Now I am having sabby 3 times say in my textview.Now I need to get the range of the second sabby word not the first...Then how would I do this... And same for other words. Because if i go with above lines of code it gives me the range of first coming word in the textview...

谢谢n.干杯....

Thanks n Cheers.....

推荐答案

使用rangeOfString:options:range:并将范围设置为在后续搜索中最后一次出现该字符串之后开始.

Use rangeOfString:options:range: and set the range to start after the last occurence of the string in subsequent searches.
