カテゴリ テーブルビューでカスタム ヘッダーを使用しています。というわけで、その条件に従って、headerとdetailを非表示にする必要があります。そこで、条件付きのヘッダーを表示するために次のコードを使用しました。
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *aView =[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 30)];
if(section==0)
{
if(![appDelegate.purchase_requisitions_preference isEqualToString:@"0"] && ![appDelegate.purchase_requisitions_preference isEqualToString:@"null"])
{
UIButton *btn=[UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 320, 30)];
btn.backgroundColor = [UIColor colorWithRed:39.0/255.0 green:131.0/255.0 blue:33.0/255.0 alpha:1.0f];
[btn setTag:section+1];
UILabel *label1 = [[UILabel alloc]init];
label1.frame = CGRectMake(20, 0, 320, 30);
label1.backgroundColor = [UIColor clearColor];
label1.textColor = [UIColor whiteColor];
label1.font = [UIFont boldSystemFontOfSize:16];
label1.text = @"Purchase Order Requisitions";
[label1 setTag:section+1];
[btn addSubview:label1];
[aView addSubview:btn];
[btn addTarget:self action:@selector(sectionTapped:) forControlEvents:UIControlEventTouchDown];
}
else
{
return nil;
}
}
else if(section==1)
{
if(![appDelegate.hr_vacancies_preference isEqualToString:@"0"] && ![appDelegate.hr_vacancies_preference isEqualToString:@"null"])
{
UIButton *btn=[UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 320, 30)];
btn.backgroundColor = [UIColor colorWithRed:39.0/255.0 green:131.0/255.0 blue:33.0/255.0 alpha:1.0f];

label1.font = [UIFont boldSystemFontOfSize:16];
label1.text = @"Human Resource Job Offers";
[label1 setTag:section+1];

条件が false の場合、ヘッダーとその詳細を非表示にします。詳細は非表示になっていますが、ヘッダーはまだ表示されています。
