我有一个像你好 - 这就是我的NSString。
我想搜索 - 并将 - 之前和之后的文本放在两个单独的字符串中。

i have an NSString like "Hello - this is me". I want to search for the "-" and put the text before and after the "-" in two separate strings.

推荐答案

NSArray *subStrings = [myString componentsSeparatedByString:@"-"]; //or rather @" - "
NSString *firstString = [subStrings objectAtIndex:0];
NSString *lastString = [subStrings objectAtIndex:1];
//Add some array range checking to it and you're done.
