IOS病例不敏感比较

我有下面的代码，比较两个值并返回匹配，问题是它区分大小写，我搜索了一下，找到了caseInsensitiveCompare方法，请帮我用caseInsensitiveCompare方法运行这个程序，我迷路了

NSString *listOfnames = @"person, person1, person2, person3";
NSString *name = @"person2";

NSRange match = [listOfnames rangeOfString:name];

 if(match.location  == NSNotFound ){
    NSLog(@"Person not found!");
}else{
    NSLog(@"Found you");
}

---

将

rangeOfString:options:

格式副本与

NSCaseInsensitiveSearch

选项一起使用：

NSString *listOfnames = @"person, person1, person2, person3";
NSString *name = @"PERSON2";

NSRange match = [listOfnames rangeOfString:name options:NSCaseInsensitiveSearch];

if(match.location  == NSNotFound ){
    NSLog(@"Person not found!");
}else{
    NSLog(@"Found you");
}
