현재 설정으로 uitableview를 다른 섹션으로 사용자 정의하려면 어떻게합니까?

Question

나는 하나의 uitableview에서 다른 섹션의 인구 주위에 내 머리를 포장 할 수없는 것. 현재 설정으로 할 수있는 방법이 있습니까? 필요한 경우 배열을 설정하는 방식을 바꾸려고합니다. 여기에 많은 쓸모없는 코드가있어 나중에 제거 하겠지만 기본적으로 모든 코드가 작동합니다. 문제는 모든 섹션에 NSMutableDictionary에 저장된 모든 데이터가로드되고 있다는 것입니다.

Answer 1

섹션을 재사용하고 코드 설정을 유지하려고하기 위해, 나는 [NSMutableArray][NSMutableArray]s의 사용을 권장합니다. 각 NSMutableArray 그런 다음 tableView:numberOfRowsInSection:에서 당신이 NSInteger PARAM를 사용하여 인덱스의 배열을 잡아 index가 section

에 해당 테이블의 섹션을 나타내는 것입니다.

인사이드 (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath indexPath.section을 통해 섹션에 액세스하고 섹션의 NSMutableArray에서 데이터를 추출 할 수 있습니다. 그런 다음 해당 섹션의 데이터에만 액세스하여 행을 만들 수 있습니다.

예 :

self.sectionArrays = [NSMutableArray new]; 

.... 


(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 
    return [self.sectionArrays count]; 

} 

(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    // Return the number of rows in the section. 
    return [[self.sectionArrays objectAtIndex:section] count]; 
} 

(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    NSArray *currentSectionArray = [self.sectionArrays objectAtIndex:indexPath.section]; 
    ... 
    NSString *toDoItem = [currentSectionArray objectAtIndex:indexPath.row]; 
    ... 
    configure cell 
}
