私はiPhoneアプリケーションで作業しており、UITableViewを使用してアプリケーションを開発しています。ユーザーがセクション1のUIButtonを押してB1メソッドを呼び出し、このテーブルビューにもう1つのセクションと行を追加すると、3つのセクションがあり、各セクションには1つの行があります。その正常に動作します。
アニメーションを追加しようとしました (セクションと行をもう 1 つ追加するため)。
  [UIView beginAnimations:nil context:nil];
  [UIView setAnimationDuration:0.2];
しかし、すべての行とセクションをアニメーション化しますが、セクションと行を追加するときにアニメーションを追加したいです。これを処理する方法を教えてください。
前もって感謝します
私はこれを試しました:
- (void)viewDidLoad
{
    [super viewDidLoad];
     ExpandActive = NO;
    self.title=@"Expand Tables";
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    if(ExpandActive == YES)
    {
        return 4; 
    }
    else
    {
         return 3;
    }
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // Return the number of rows in the section.
    return 1;
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section{
    if(ExpandActive == YES)
    {
        if(section == 0)
        {
            return @"Header1";
        }
        else  if(section == 1)
        {
             return @"Header1";
        }
        else if(section == 2)
        {
             return @"Header1";    
        }
        else if(section == 3)
        {
             return @"Header1";
        }
    }
    else
    {
        if(section == 0)
        {
             return @"Header1";
        }
        else  if(section == 1)
        {
             return @"Header1";
        }
        else if(section == 2)
        {
             return @"Header1";
        }
    }   
}
