Question

我在我的iphone应用程序上进行搜索屏幕（搜索名称列表），我需要使用名字和姓氏进行搜索

说我的搜索表视图包含如下名称

Ravi Kiran 
sujay huilgol
harry potter

我的搜索仅适用于名字，即如果我搜索 Ra ，则显示 Ravi Kiran 但是当我搜索 Kiran 时没有显示 Ravi Kiran

我的 filterContentForSearchText 就像这样

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
    [self.arrSearhResults removeAllObjects]; // First clear the filtered array.

    // Search the main list for Usenames whose type matches searchText; add items that match to the filtered array.

    for(NSString * strUserName in arrUserInfo )
    {
        NSComparisonResult result = [strUserName compare:searchText options:(NSLiteralSearch|NSDiacriticInsensitiveSearch) range:NSMakeRange(0, [searchText length])];
        if (result == NSOrderedSame)
        {
            // Update the filtered array based on the search text and scope.
            [self.arrSearhResults addObject:strUserName];
            //NSLog(@"arrSearhResults %@",arrSearhResults);
        }
    }

}

任何人都可以提前帮助我.......提前！

Answer 1

试试这个：

for(NSString * strUserName in arrUserInfo )
{
  NSRange titleResultsRange = [[NSString stringWithFormat:@"%@",strUserName] rangeOfString:searchText options:NSCaseInsensitiveSearch];
    if (titleResultsRange.length){
        [self.arrSearhResults addObject:[self.contacts objectAtIndex:i]];
    }
}

Answer 2

使用 rangeOfString 搜索整个字符串

 for(NSString * strUserName in arrUserInfo )
{
  NSRange range = [strUserName rangeOfString:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch)];
  if (range.length > 0)
  {
    [self.arrSearhResults addObject:strUserName];
  }
}

Answer 3

NSArray *array = [[NSArray alloc] initWithObjects:@"Ravi Kiran", @"sujay huilgol", nil];
for (NSString* name in array)
{
    if ([name rangeOfString:@"Kiran"].location != NSNotFound)
        NSLog(@"%@", name);
}
