通过 NSArray 搜索字符串

问题描述

我想在我的 NSArray 中搜索某个字符串.

I would like to search through my NSArray for a certain string.

示例:

NSArray 有对象:dog"、cat"、fat dog"、thing"、another thing"、heck here's another thing"

NSArray has the objects: "dog", "cat", "fat dog", "thing", "another thing", "heck here's another thing"

我想搜索单词another"并将结果放入一个数组中，并将另一个非结果放入另一个可以进一步过滤的数组中.

I want to search for the word "another" and put the results into one array, and have the other, non results, into another array that can be filtered further.

推荐答案

未测试所以可能有语法错误，但你会明白的.

Not tested so might have a syntax error, but you'll get the idea.

NSArray* inputArray = [NSArray arrayWithObjects:@"dog", @"cat", @"fat dog", @"thing", @"another thing", @"heck here's another thing", nil];

NSMutableArray* containsAnother = [NSMutableArray array];
NSMutableArray* doesntContainAnother = [NSMutableArray array];

for (NSString* item in inputArray)
{
  if ([item rangeOfString:@"another"].location != NSNotFound)
    [containsAnother addObject:item];
  else
    [doesntContainAnother addObject:item];
}
