搜索NSMutableArray时NSCFString countByEnumeratingWithState:objects:count:ERROR

Question

我有以下情况,我NSMutableArray填写了一个xml我想搜索的文件.当我在搜索字段中输入内容时出现此错误:

-[NSCFString countByEnumeratingWithState:objects:count:]: unrecognized selector sent to instance 0x5b388b0

它意味着什么,我该如何解决？

我想错误就在这附近.

- (void)searchTableView{

 searchedList = [[NSMutableArray alloc] init];
 NSLog(@"new list %@", searchedList);
 NSString *searchText = searchBar.text;
 NSMutableArray *searchArray = [[NSMutableArray alloc] init];

 for (NSDictionary *dictionary in list) {
    NSArray *array = [dictionary objectForKey:@"TITLE"];
   [searchArray addObjectsFromArray:array];
 }

 for (NSString *TempArray in searchArray) {
  NSRange titleResults = [TempArray rangeOfString:searchText options:NSCaseInsensitiveSearch];
  if (titleResults.length > 0) 
  [searchedList addObject:TempArray];
 }
 [searchArray release];
 searchArray = nil;
}

Answer 1

这意味着您正在调用为NSArray设计的方法(countByEnumeratingWithState:objects:count在NSString上).

我不知道这段代码是否是您的代码复制/粘贴,但如果是这样,在您使用的最后,您[searchList addObject:TempArray]没有一个名为的对象searchList.

另外,处理您的命名约定.重要时刻.
