테이블보기에서 겹치는 셀

Question

셀 및 텍스트 필드가있는 UITableView를 구현하려고하지만 셀이 겹치기 때문에 텍스트 필드가 한 섹션에서 다른 섹션으로 건너 뜁니다.

누군가 내 코드에서 내가 수행 한 실수를 확인할 수 있습니까?

listForItemsinfo =[[NSArray alloc]initWithObjects:@"Name",@"Price", nil]; 
listForBrandYear =[[NSArray alloc] initWithObjects:@"Year",@"Alfa",@"aston",@"audi",@"bentley",@"BMW",@"Cadillac",@"Chevrolet",@"Ferrari",@"Ford",@"Jaguar",@"Jeep",@"Kia",@"Landrover",@"Mazda",@"Mercedes",@"Mitsubishi",@"Nissan",@"Porshe",@"Subaru", nil]; 



listForkeywords =[[NSArray alloc] initWithObjects:@"KeyWord1",@"Keyword2", nil]; 
listForcarType =[[NSArray alloc] initWithObjects:@"Sedan",@"Convertible",@"Coupe",@"Heatchback", nil]; 
listForItemsCategory =[[NSArray alloc] initWithObjects:@"cat1",@"cat2",@"cat3",@"cat4",@"cat5",@"cat6", nil]; 

sections = [[NSArray alloc]initWithObjects:@"Item's info",@"Brand, Year",@"Keywords",@"Car Type",@"Category", nil]; 
listOfsections =[[NSArray alloc]initWithObjects:listForItemsinfo,listForBrandYear,listForkeywords,listForcarType,listForItemsCategory, nil];

테이블이 있지만 세포 경우 재사용 얻을 않습니다. 문제는 초기화 할 때 셀을 구성하는 것뿐입니다. 사실 새 셀을 만들거나 이전 셀을 만들 때 -dequeueReusableCellWithIdentifier:에서 해당 구성을 수행해야합니다.

아마도 테이블보기에서 모든 셀을 저장한다고 생각했을 것입니까? 재사용이 가능한 세포는 한 번에 표시 할 수있는만큼 많은 세포가 필요하다는 것을 의미합니다. 보기를 스크롤하면 위쪽 또는 아래쪽으로 스크롤되는 셀이 새 내용의 새 셀로 재활용됩니다. 새로운 콘텐츠를 설정하지 않으므로 이전 콘텐츠가 대신 표시됩니다. 코드의 나머지 부분이 항상 실행되도록
