모든 UITableView 섹션의 하단에 버튼을 삽입하는 방법은 무엇입니까?

Question

현재 MatchCenterViewController에 UITableView이 있고 모든 섹션에 대해 10 개의 행을로드하도록 설계되었지만 나머지 부분은 heightForRowAtIndexPath으로 0을 반환하여 처음 4 개만 표시합니다. 내가하고 싶은 일은 각 섹션의 맨 아래에 버튼을 눌러 데이터를 다시로드하고 해당 섹션에 대해 4 대신 10을 표시하는 것입니다.

버튼을 눌렀을 때 무슨 일이 일어나는지 프레임 워크 작업을 시작했습니다. 아래쪽 버튼을 렌더링하고 해당 섹션에만 10 개의 행을 표시하는 구문에 문제가 있습니다. 여기에 내가 가진 방법은 내 UITableView 지금까지 배치 :

Answer 1

을 당신도 특별있는 UITableViewCell을 사용하여이 기능을 또는 UITableView의 footerView

Answer 2

요 속성 tableFooterView을 사용할 수 있습니다. 나는 지금 용지를 더 옵션

UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 65)]; 
v.backgroundColor = [UIColor clearColor]; 

int mySiz = 0; 
// keep counter how many times load more is pressed.. initial is 0 (this is like index) 
mySiz = [startNumberLabel.text intValue]+1; 


// i have 15 bcz my index size is 15. 
if ([feeds count]>=(15*mySiz)) { 
    NSLog(@"showing button..."); 
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [button setFrame:CGRectMake(10, 10, 296, 45)]; 
    [button setBackgroundImage:[UIImage imageNamed:localize(@"loadmore")] forState:UIControlStateNormal]; 
    [button addTarget:self action:@selector(loadMoreData:) forControlEvents:UIControlEventTouchUpInside]; 
    [v addSubview:button]; 
    mainTableView.tableFooterView = v; 
} else { 
    mainTableView.tableFooterView = nil; 
} 

[mainTableView reloadData]; 

당신의 필요에 따라 코드를 조정을 보여주는에 사용하는 방법 아래

과 같이 그 일을 최대 종료 :

// Create "more" button 
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section { 
    UIView *view = [[UIView alloc] initWithFrame:CGRectZero]; 
    view.backgroundColor = [UIColor whiteColor]; 

    self.moreButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    self.moreButton.frame = CGRectMake(0, 0, 320, 44); 
    [self.moreButton setImage:[UIImage imageNamed:@"downarrow.png"] forState:UIControlStateNormal]; 
    [self.moreButton addTarget:self action:@selector(moreButtonSelected:) forControlEvents:UIControlEventTouchUpInside]; 
    [view addSubview:self.moreButton]; 

    return view; 
} 

// Load rest of items 
- (void)moreButtonSelected:(id)sender { 
    if (_hasPressedShowMoreButton == NO){ 
     self.hasPressedShowMoreButton = YES; 
    } 
    else if (_hasPressedShowMoreButton == YES){ 
     self.hasPressedShowMoreButton = NO; 
    } 

    [self.matchCenter reloadData]; 
}
