搜索NSMutableArray时NSCFString countByEnumeratingWithState：objects：count：ERROR [英] NSCFString countByEnumeratingWithState:objects:count: ERROR while searching NSMutableArray

问题描述

我有以下情况：
我有一个 NSMutableArray 填充了 xml 文件，其中我想要搜索。
当我在搜索字段中输入内容时，我收到此错误：

I have the following situation where I have an NSMutableArray filled with an xml file which I want to search. When I enter something in the search field I get this Error:

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

这意味着什么以及如何解决？

What does it means and how can I fix it??

我认为错误就在这附近。

I suppose the error is somewhere around here.

- (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;
}

推荐答案

这意味着你正在呼叫为NSArray设计的方法（ countByEnumeratingWithState：objects：count 在NSString上。

it means you are calling a method designed for an NSArray (countByEnumeratingWithState:objects:count on a NSString.

我不知道是否这个代码是从你的复制/粘贴，但如果是这样，在你使用 [searchList addObject：TempArray] 的末尾，你没有一个名为的对象searchList 。

I don't know ifthis code is copy/paste from yours, but if so, at the end where you use [searchList addObject:TempArray] you don't have an object named searchList.

此外，处理您的命名约定。大时间。

Also, work on your naming conventions. big time.
