NSString 在整个文本中搜索另一个字符串 [英] NSString search whole text for another string

问题描述

我想在另一个NSString中搜索一个NSString，这样即使第二个不以第一个开头也能找到结果，例如:

I would like to search for an NSString in another NSString, such that the result is found even if the second one does not start with the first one, for example:

例如:我有一个搜索字符串st".我查看下面的记录，看看下面是否有任何包含这个搜索字符串，它们都应该返回一个好的结果，因为它们都有st".

eg: I have a search string "st". I look in the following records to see if any of the below contains this search string, all of them should return a good result, because all of them have "st".

目前我正在做以下事情:

At the moment I am doing the following:

NSComparisonResult result = [selectedString compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])];

这仅适用于上例中的stable"，因为它以st"开头，而其他 2 则失败.如何修改此搜索以使其对所有 3 都返回 ok?

This works only for "stable" in the above example, because it starts with "st" and fails for the other 2. How can I modify this search so that it returns ok for all the 3?

谢谢！！！

推荐答案

为什么不先google?

Why not google first?

字符串包含objective-c中的字符串

NSString *string = @"hello bla bla";
if ([string rangeOfString:@"bla"].location == NSNotFound) {
  NSLog(@"string does not contain bla");
} else {
  NSLog(@"string contains bla!");
}
