Question

I have to search a word in an array using UISearchBar. for example i have "Chicken Salad" string in an array at index 2. now if want to search it using last word "Salad" then what should i do? for the time i am using this code and it is working good but if you search from first word.

(appDelegate.isAirlineSelection == YES) {
            for (int i = 0; i < [menuArray count]; i++) {
                if ([[[[menuArray objectAtIndex:i] itemName] uppercaseString] hasPrefix:search]||[[[[menuArray objectAtIndex:i] itemName] uppercaseString] hasSuffix:search]) {
                    [tableMenuArray addObject:[menuArray objectAtIndex:i]];
                    NSLog(@"Found");
                }
            }

帮帮我吧

Answer 1

尝试这个方式, 它会在字词之间搜索 :

for(NSString *name in menuArray)        
{
    if ([name rangeOfString:search options:NSLiteralSearch|NSCaseInsensitiveSearch].location != NSNotFound)
        [tableMenuArray addObject:name];
            NSLog(@"Found");

}

首先,您应该将阵列名称分成两个部分,创建两个阵列,然后可以很容易地使用第二个阵列的搜索栏,并找到准确的结果,你要什么。

for (NSString *name in lastnames)
    {

            NSComparisonResult result = [name compare:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])];
            if (result == NSOrderedSame)
            {
                [searchedNames addObject:name];
            }

    }
