저는이 응용 프로그램에 익숙하지 않고 UISearchBar을 사용합니다. 검색 할 단어를 입력하면 응용 프로그램이 충돌합니다.iPhone : 검색 막대가 TableView에서 사용되면 응용 프로그램이 충돌 함

내 프로젝트에서 나는 sqlite를 사용하고 있으며 값은 AppDelegate의 db에서 가져오고 이라는 이름의 docArray에 저장됩니다. 오류 다음

업데이트 된 정보를 제공해 주셔서 감사합니다. 아래에서 제안 된 해결 방법을 참조하십시오. 이것으로부터 배울 점 중 하나는 핵심 오류가 아래에 설명 된 이유 때문에'- [waitsup rangeOfString : options :] : 인스턴스 0x6d0f8e0으로 보낸 인식 할 수없는 선택자 '입니다. – mvds

그래서 우리는 모든 줄 바꿈을 스크롤 할 필요가 없습니다. 또한,이 테이블보기의는 dataSource이며, 만약 그렇다면, 어디에 :

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

가 실패하고 충돌의 원인이 될 수 있습니다 copyListOfItems에 액세스해야합니다.

콘솔이 충돌 할 때 표시되는 내용은 무엇입니까?

편집 : 추가 정보를 제공해 주셔서 감사합니다. 귀하의 문제는 여기에있다 :

for (NSString *sTemp in searchArray)

searchArray는 "waitsup"객체, 내가 NSString하지 생각이 포함되어 있습니다. 이 포인터를 NSString 포인터로 캐스팅했지만 실제로는 NSString 개체를 가리키는 것은 사용자의 책임입니다. 따라서 waitsup에서 rangeOfString이 호출되는 오류가 발생합니다.이 오류는 "인식 할 수 없음"입니다. rangeOfString 메서드를 직접 제공하지 않았다면 waitsup 개체에서 rangeOfString을 호출 할 수 없습니다. 코드의 나머지 부분을 보면

, 나는이 같은 문제를 해결할 수 있다고 생각 : 

for (waitsup *sTemp in searchArray) { 
    NSRange titleResultsRange = [sTemp.name_last rangeOfString:searchText options:NSCaseInsensitiveSearch]; 
    if (titleResultsRange.length > 0) 
     [copyListOfItems addObject:sTemp]; 
}

하지만 만 name_last가 검색됩니다. 이 필드를 확장하여 더 많은 필드를 포함시키는 것은 쉽습니다.
