iOS 7の iPad 設定アプリケーションの詳細ビューと同じスタイルのグループ UITableView が必要です。

角を丸くしたtableViewです。詳細は添付ファイルをご確認ください。

そのように見えるようにするためのデフォルト設定があるか、同じようにカスタム描画を行う必要があります。

正しい方向へのヒントをいただければ幸いです。

ありがとう

先に進み、willDisplayCell をさらにカスタマイズして、設定アプリでセル スタイルのシミュレーションを改善しました。

Objective-C

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    if ([cell respondsToSelector:@selector(tintColor)]) {
        if (tableView == self.tableView) {
            CGFloat cornerRadius = 5.f;
            cell.backgroundColor = UIColor.clearColor;
            CAShapeLayer *layer = [[CAShapeLayer alloc] init];
            CGMutablePathRef pathRef = CGPathCreateMutable();
            CGRect bounds = CGRectInset(cell.bounds, 10, 0);
            BOOL addLine = NO;
            if (indexPath.row == 0 && indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1) {
                CGPathAddRoundedRect(pathRef, nil, bounds, cornerRadius, cornerRadius);
            } else if (indexPath.row == 0) {
                CGPathMoveToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMaxY(bounds));
                CGPathAddArcToPoint(pathRef, nil, CGRectGetMinX(bounds), CGRectGetMinY(bounds), CGRectGetMidX(bounds), CGRectGetMinY(bounds), cornerRadius);
                CGPathAddArcToPoint(pathRef, nil, CGRectGetMaxX(bounds), CGRectGetMinY(bounds), CGRectGetMaxX(bounds), CGRectGetMidY(bounds), cornerRadius);

@jvanmetreによる答えは素晴らしく、うまくいきます。その上に構築し、コメントで@SergiySalyukが提案したように。代わりに UIBezierPath を使用するようにコードを更新して、理解しやすく、わずかに高速にしました。

私のバージョンでは、区切りのバグも修正され、セルに合わせて選択された背景ビューが追加されます。

テーブルビューを区切りなしに設定することを忘れないでください:tableView.separatorStyle = UITableViewCellSeparatorStyleNone;

Objective-C

- (void)tableView:(UITableView*)tableView willDisplayCell:(UITableViewCell*)cell forRowAtIndexPath:(NSIndexPath*)indexPath {
  // Set transparent background so we can see the layer
  cell.backgroundColor = UIColor.clearColor;

  // Declare two layers: one for the background and one for the selecetdBackground
  CAShapeLayer *backgroundLayer = [CAShapeLayer layer];
  CAShapeLayer *selectedBackgroundLayer = [[CAShapeLayer alloc] init];

  CGRect bounds = CGRectInset(cell.bounds, 0, 0);//Cell bounds feel free to adjust insets.

  BOOL addSeparator = NO;// Controls if we should add a seperator

  // Determine which corners should be rounded
  if (indexPath.row == 0 && indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1) {
    // This is the only row in its section, round all corners
    backgroundLayer.path = [UIBezierPath bezierPathWithRoundedRect:bounds byRoundingCorners:UIRectCornerAllCorners cornerRadii:CGSizeMake(7, 7)].CGPath;

  } else if (indexPath.row == 0) {
    // First row, round the top two corners.
    backgroundLayer.path = [UIBezierPath bezierPathWithRoundedRect:bounds byRoundingCorners:UIRectCornerTopLeft | UIRectCornerTopRight cornerRadii:CGSizeMake(7, 7)].CGPath;
    addSeparator = YES;

  } else if (indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1) {
    // Bottom row, round the bottom two corners.
    backgroundLayer.path = [UIBezierPath bezierPathWithRoundedRect:bounds byRoundingCorners:UIRectCornerBottomLeft | UIRectCornerBottomRight cornerRadii:CGSizeMake(7, 7)].CGPath;

  } else {
    // Somewhere between the first and last row don't round anything but add a seperator
    backgroundLayer.path = [UIBezierPath bezierPathWithRect:bounds].CGPath;// So we have a background
    addSeparator = YES;
  }

  // Copy the same path for the selected background layer
  selectedBackgroundLayer.path = CGPathCreateCopy(backgroundLayer.path);

  // Yay colors!
  backgroundLayer.fillColor = [UIColor colorWithWhite:1.f alpha:0.8f].CGColor;
  selectedBackgroundLayer.fillColor = [UIColor grayColor].CGColor;

  // Draw seperator if necessary
  if (addSeparator == YES) {
    CALayer *separatorLayer = [CALayer layer];
    CGFloat separatorHeight = (1.f / [UIScreen mainScreen].scale);
    separatorLayer.frame = CGRectMake(CGRectGetMinX(bounds)+10, bounds.size.height-separatorHeight, bounds.size.width-10, separatorHeight);
    separatorLayer.backgroundColor = tableView.separatorColor.CGColor;

    [backgroundLayer addSublayer:separatorLayer];
  }

  // Create a UIView from these layers and set them to the cell's .backgroundView and .selectedBackgroundView
  UIView *backgroundView = [[UIView alloc] initWithFrame:bounds];
  [backgroundView.layer insertSublayer:backgroundLayer atIndex:0];
  backgroundView.backgroundColor = UIColor.clearColor;
  cell.backgroundView = backgroundView;

  UIView *selectedBackgroundView = [[UIView alloc] initWithFrame:bounds];
  [selectedBackgroundView.layer insertSublayer:selectedBackgroundLayer atIndex:0];
  selectedBackgroundView.backgroundColor = UIColor.clearColor;
  cell.selectedBackgroundView = selectedBackgroundView;

    NSInteger MBRows = [self numberOfRowsInSection:indexPath.section] - 1;
    CAShapeLayer    *MBLayer = [[CAShapeLayer alloc] init];
    CGRect cellBounds = CGRectMake(0, 0, self.bounds.size.width, cell.bounds.size.height);

    BOOL shouldAddSeperator = NO;

    if (indexPath.row == 0 && indexPath.row == MBRows) {
        [MBLayer setPath:[UIBezierPath bezierPathWithRoundedRect:cellBounds cornerRadius:radius].CGPath];
    } else if (indexPath.row == 0) {

これを行う簡単な方法はないようです。UITableViewCell をカスタマイズする必要があります。次のように機能します。ここに画像の説明を入力

tableView のスタイルをグループ化に設定します。

TableView の背景色をクリア カラーに設定します。

あなたの -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)セルの背景を明確にし、目的の丸みを帯びた角を持つ UIView を背景として作成します。このようなもの：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];

    if(cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
    }

    [cell setBackgroundColor:[UIColor clearColor]];

    UIView *roundedView = [[UIView alloc] initWithFrame:cell.frame];
    [roundedView setBackgroundColor:[UIColor whiteColor]];
    roundedView.layer.cornerRadius = 10.0;
    [[cell contentView] addSubview:roundedView];


    return cell;
}

さらに磨きをかける必要があるかもしれませんが、これが主なアイデアです。

このコードは、単一のセルではなく、テーブル ビュー全体の角を丸く設定します。

UIView *roundedView = [[UIView alloc] initWithFrame:CGRectInset(table.frame, 5, 0)];
roundedView.backgroundColor = [UIColor colorWithWhite:1.f alpha:0.8f];
roundedView.layer.cornerRadius = 5.f;
[self.view addSubview:roundedView];
[roundedView release];
[self.view addSubview:table];

cellForRow の各セルの背景色をクリアします

cell.backgroundColor=[UIColor clearColor];

これを追加して、テーブルビューの一番上の行を削除します self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
