Question

我正在尝试在tableview中插入一个搜索栏，其中包含来自Arrays的NSDictionary的信息。每个数组都包含对象。每个对象都有几个属性，例如Name或Address。

我已经实现了NSSearchBar的方法，但是对应于自己搜索的代码，我已经处理了另一个只有字符串只有字符串的项目，它不起作用，我无法解决问题。

这是代码： 'indiceLateral'是一个带字母的数组; 'partners'是一个NSDictionary; 'RLPartnersClass'是我的合作伙伴类别，每个合作伙伴都有属性（名称，地址，......）。

-(void)handleSearchForTerm:(NSString *)searchTerm {

 NSMutableArray *sectionsToRemove = [[NSMutableArray alloc] init];
 [self resetSearch];

 for (NSString *key in self.indiceLateral) {
  NSMutableArray *array = [partners valueForKey:key];
  NSMutableArray *toRemove = [[NSMutableArray alloc] init];

  for (NSString *name in array) {
   if ([name rangeOfString:searchTerm options:NSCaseInsensitiveSearch].location == NSNotFound)
    [toRemove addObject:name];
  }

  if ([array count] == [toRemove count])
   [sectionsToRemove addObject:key];
  [array removeObjectsInArray:toRemove];
  [toRemove release];
 }

 [self.indiceLateral removeObjectsInArray:sectionsToRemove];

 [sectionsToRemove release];
 [theTable reloadData];
}

有人可以帮我吗？

谢谢，

我已经完成了。

示例：

-(void)handleSearchForTerm:(NSString *)searchTerm {

    NSMutableDictionary *finalDict = [NSMutableDictionary new];
    NSString *currentLetter = [[NSString alloc] init];

    for (int i=0; i<[indiceLateral count]; i++) {
        NSMutableArray *elementsToDict = [[[NSMutableArray alloc] init] autorelease];
        currentLetter = [indiceLateral objectAtIndex:i];

        NSArray *partnersForKey = [[NSArray alloc] initWithArray:[partnersCopy objectForKey:[indiceLateral objectAtIndex:i]]];

        for (int j=0; j<[partnersForKey count]; j++) {
            RLNames *partnerInKey = [partnersForKey objectAtIndex:j];

            NSRange titleResultsRange = [partnerInKey.clientName rangeOfString:searchTerm options:NSDiacriticInsensitiveSearch | NSCaseInsensitiveSearch];

            if (titleResultsRange.length > 0){
                NSLog(@"found: %@", partnerInKey.clienteCity
                [elementsToDict addObject:partnerInKey];
            }
        }

        [finalDict setValue:elementsToDict forKey:currentLetter];
    }

    NSMutableDictionary *finalResultDict = [finalDict mutableDeepCopy];
    self.partners = finalResultDict;
    [finalResultDict release];

    [theTable reloadData];
}
