iPad의 설정 앱에서와 같은 iOS 7 TableView

iOS 7 용 iPad 설정 응용 프로그램 세부 정보보기 와 같은 스타일의 그룹 UITableView를 갖고 싶습니다 .

모서리가 둥근 tableView입니다. 자세한 내용은 첨부 파일을 확인하십시오.

그렇게 보이게하기위한 몇 가지 기본 설정이거나 같은 것에 대해 사용자 정의 드로잉을해야합니다.

올바른 방향으로 힌트를 주시면 감사하겠습니다.

설정 앱에서 셀 스타일을 더 잘 시뮬레이션하기 위해 willDisplayCell을 추가로 사용자 정의했습니다.

iOS 13 이상에서이 테이블 스타일은 새로운 UITableView.Style.insetGrouped 테이블 뷰 스타일 로 다시 엔지니어링 할 필요없이 Apple에서 마침내 사용할 수있게되었습니다 .

Xcode 11 이상에서는 스타일에 대해 Inset Grouped를 선택하여 테이블보기의 인터페이스 빌더 설정에서 설정할 수 있습니다.

전체 셀이 강조 표시된 것처럼 보이지 않도록 셀의 배경보기를 설정하는 방법에 대해 @NarasimhaiahKolli에 응답합니다. 도움이 되었기를 바랍니다.

@jvanmetre의 대답은 훌륭하고 작동합니다. 그 위에 구축하고 댓글에서 @SergiySalyuk이 제안한대로. 대신 UIBezierPath를 사용하도록 코드를 업데이트하여 이해하기 쉽고 약간 더 빠르게 만들었습니다.

https://github.com/TimOliver/TORoundedTableView

결국 매우 복잡한 프로세스가되었습니다.

• 나는 하위 클래스 layoutSubviews를UITableView 각 셀과 액세서리 뷰를 중계 해야했기 때문에 더 이상 에지 투 에지가 아니었다.
• 나는 서브 클래스를해야했다 UITableViewCell상단 및 하단 구분선보기를 제거하기 위해 를 만들어야했습니다 (단, 섹션 내부의보기는 그대로 둡니다).
• 그런 다음 UITableViewCell각 섹션의 첫 번째 및 마지막 셀에 사용할 상단과 하단에 둥근 모서리를 선택적으로 포함 할 수 있는 사용자 지정 배경보기 를 만들었습니다 . 이러한 요소는 사용자가 셀을 탭할 때 배경 뷰의 색상을 변경하는의 암시 적 동작 CALayer을 방지해야했습니다 UITableView.
• 이제는에 CALayer응답하지 않는 인스턴스 이기 때문에 layoutSubviews사용자가 장치를 회전 할 때 상단 및 하단 셀의 크기가 다른 셀과 동일한 속도로 조정되도록하기 위해 코어 애니메이션 땜질을해야했습니다.

대체로 할 수는 있지만 상당한 노력이 필요하고 약간의 성능이 필요하기 때문에 (모든 것을 되돌리려는 Apple의 코드와 지속적으로 싸우기 때문에) Apple에 요청하는 것이 가장 좋습니다. 공식적으로 그 스타일을 공개합니다. 그때까지는 내 라이브러리를 자유롭게 사용하십시오. :)

addRoundedCornersWithRadius:(CGFloat)radius ForCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath모든 섹션의 상단과 하단에 둥근 모서리를 만드는 메서드를 만들었습니다 .

의 maskView속성 을 사용하는 이점은 UITableViewCell셀을 선택할 때 둥근 모서리가 계속 표시된다는 것입니다.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"CellIdentifier"];
    [cell.textLabel setText:[NSString stringWithFormat:@"Row %d in Section %d", indexPath.row, indexPath.section]];
    [tableView addRoundedCornersWithRadius:12.0f ForCell:cell atIndexPath:indexPath];
    return cell;
}

- (void)addRoundedCornersWithRadius:(CGFloat)radius ForCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath {
    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) {
        [MBLayer setPath:[UIBezierPath bezierPathWithRoundedRect:cellBounds
                                               byRoundingCorners:(UIRectCornerTopLeft|UIRectCornerTopRight)
                                                     cornerRadii:CGSizeMake(radius, radius)].CGPath];
        shouldAddSeperator = YES;
    } else if (indexPath.row == MBRows) {
        [MBLayer setPath:[UIBezierPath bezierPathWithRoundedRect:cellBounds
                                               byRoundingCorners:(UIRectCornerBottomLeft|UIRectCornerBottomRight)
                                                     cornerRadii:CGSizeMake(radius, radius)].CGPath];
    } else {
        [MBLayer setPath:[UIBezierPath bezierPathWithRect:cell.bounds].CGPath];
        shouldAddSeperator = YES;
    }

    [cell setMaskView:[[UIView alloc] initWithFrame:cell.bounds]];
    [cell.maskView.layer insertSublayer:MBLayer atIndex:0];

    if (shouldAddSeperator == YES) {
        CGFloat seperator = (1.0f / [UIScreen mainScreen].scale);
        CALayer *cellSeperator = [[CALayer alloc] init];

        [cellSeperator setFrame:CGRectMake(15.0f, cell.bounds.size.height - seperator, cell.bounds.size.width - 15.0f, seperator)];
        [cellSeperator setBackgroundColor:self.separatorColor.CGColor];
        [cell.layer addSublayer:cellSeperator];
    }

    [cell.maskView.layer setMasksToBounds:YES];
    [cell setClipsToBounds:YES];
}

내 대답은 너무 늦을 수 있지만 Swift 버전 (모든)의 경우 확실히 유용하고 사용하기 쉽습니다.

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
        if (tableView == self.tableViewMovies) {
            //Top Left Right Corners
            let maskPathTop = UIBezierPath(roundedRect: cell.bounds, byRoundingCorners: [.topLeft, .topRight], cornerRadii: CGSize(width: 5.0, height: 5.0))
            let shapeLayerTop = CAShapeLayer()
            shapeLayerTop.frame = cell.bounds
            shapeLayerTop.path = maskPathTop.cgPath

            //Bottom Left Right Corners
            let maskPathBottom = UIBezierPath(roundedRect: cell.bounds, byRoundingCorners: [.bottomLeft, .bottomRight], cornerRadii: CGSize(width: 5.0, height: 5.0))
            let shapeLayerBottom = CAShapeLayer()
            shapeLayerBottom.frame = cell.bounds
            shapeLayerBottom.path = maskPathBottom.cgPath

            if (indexPath as NSIndexPath).section == 0 {
                if indexPath.row == 0 {
                    cell.layer.mask = shapeLayerTop
                }else if indexPath.row == 2 {
                    cell.layer.mask = shapeLayerBottom
                }
            }else if (indexPath as NSIndexPath).section == 1 {
                if indexPath.row == 0 {
                    cell.layer.mask = shapeLayerTop
                }else {
                    cell.layer.mask = shapeLayerBottom
                }
            }else if (indexPath as NSIndexPath).section == 2 {
                if indexPath.row == 0 {
                    cell.layer.mask = shapeLayerTop
                }else if indexPath.row == 2 {
                    cell.layer.mask = shapeLayerBottom
                }
            }
        }
    }

추신 : Swift 3.0에 다음 코드를 사용했습니다.

 func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath)
{
    if (tableView == self.orderDetailsTableView)
    {
        //Top Left Right Corners
        let maskPathTop = UIBezierPath(roundedRect: cell.bounds, byRoundingCorners: [.TopLeft, .TopRight], cornerRadii: CGSize(width: 5.0, height: 5.0))
        let shapeLayerTop = CAShapeLayer()
        shapeLayerTop.frame = cell.bounds
        shapeLayerTop.path = maskPathTop.CGPath

        //Bottom Left Right Corners
        let maskPathBottom = UIBezierPath(roundedRect: cell.bounds, byRoundingCorners: [.BottomLeft, .BottomRight], cornerRadii: CGSize(width: 5.0, height: 5.0))
        let shapeLayerBottom = CAShapeLayer()
        shapeLayerBottom.frame = cell.bounds
        shapeLayerBottom.path = maskPathBottom.CGPath

        //All Corners
        let maskPathAll = UIBezierPath(roundedRect: cell.bounds, byRoundingCorners: [.TopLeft, .TopRight, .BottomRight, .BottomLeft], cornerRadii: CGSize(width: 5.0, height: 5.0))
        let shapeLayerAll = CAShapeLayer()
        shapeLayerAll.frame = cell.bounds
        shapeLayerAll.path = maskPathAll.CGPath

        if (indexPath.row == 0 && indexPath.row == tableView.numberOfRowsInSection(indexPath.section)-1)
        {
            cell.layer.mask = shapeLayerAll
        }
     else if (indexPath.row == 0)
        {
        cell.layer.mask = shapeLayerTop
        }
        else if (indexPath.row == tableView.numberOfRowsInSection(indexPath.section)-1)
        {
            cell.layer.mask = shapeLayerBottom
        }
    }
}

신속한 작업 코드 ... 실제로 우리가하는 것은 섹션에 행이 하나만 있으면 모든면에서 수행하고 섹션에 여러 행이 있으면 첫 번째 행에서 맨 위를 수행하고 마지막 행에서 맨 아래로 수행하는 것입니다. 속성 BottomLeft, BottomRight, topLeft, TopRight는 rect corner 유형이어야합니다 (입력 할 때 xcode의 제안 ... 동일한 이름을 가진 다른 속성 콘텐츠 코너가 있습니다 .. 확인하십시오)

이 작업을 수행하는 쉬운 방법이없는 것 같습니다. 다음과 같이 UITableViewCell을 사용자 정의해야합니다.

tableView의 스타일을 그룹화로 설정하십시오.

TableView 배경색을 명확한 색상으로 설정하십시오.

당신의- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)셀 배경을 지우고 원하는 둥근 모서리를 배경으로 UIView를 만듭니다. 이 같은:

- (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;
}

좀 더 다듬어야 할 수도 있지만 이것이 주요 아이디어입니다.

나는 동일하지만 각 섹션 주위에 테두리를 만들고 싶었습니다 (iOS6의 줄). 제안 된 솔루션을 쉽게 수정할 수 없었기 때문에 내 솔루션을 생각해 냈습니다. 이 주제 에서 @Roberto Ferraz가 준 답변을 수정 한 것입니다 . UITableViewCell에서 상속하는 사용자 지정 클래스를 만들었습니다. 여기에 적절한 크기의 컨테이너 뷰를 추가했습니다 (제 경우에는 양쪽이 15px로 축소됨). 수업에서 나는 이것을했다 :

- (void)layoutSubviews
{
    [super layoutSubviews];
    
    CGFloat cornerRadius = 10.0f;
    
    self.vContainerView.layer.cornerRadius = cornerRadius;
    self.vContainerView.layer.masksToBounds = YES;
    self.vContainerView.layer.borderWidth = 1.0f;
    
    if (self.top && self.bottom)
    {
        // nothing to do - cell is initialized in prepareForReuse
    }
    else if (self.top)
    {
        // cell is on top - extend height to hide bottom line and corners
        CGRect frame = self.vContainerView.frame;
        frame.size.height += cornerRadius;
        self.vContainerView.frame = frame;
    
        self.vSeparatorLine.hidden = NO;
    }
    else if (self.bottom)
    {
        // cell is on bottom - extend height and shift container view up to hide top line and corners
        CGRect frame = self.vContainerView.frame;
        frame.size.height += cornerRadius;
        frame.origin.y -= cornerRadius;
        self.vContainerView.frame = frame;
    
        self.vSeparatorLine.hidden = YES;
    }
    else
    {
        // cell is in the middle - extend height twice the height of corners and shift container view by the height of corners - therefore hide top and bottom lines and corners.
        CGRect frame = self.vContainerView.frame;
        frame.size.height += (2 * cornerRadius);
        frame.origin.y -= cornerRadius;
        self.vContainerView.frame = frame;
    
        self.vSeparatorLine.hidden = NO;
    }
}

- (void)prepareForReuse
{
    // establish original values when cell is reused
    CGRect frame = self.vBorderView.frame;
    frame.size.height = BORDER_VIEW_HEIGHT;
    frame.origin.y = 0;
    self.vBorderView.frame = frame;
    
    self.vSeparatorLine.hidden = YES;
}

그런 다음 데이터 소스에서 다음을 수행합니다.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    ...
    
    // only one cell in section - must be rounded on top & bottom
    if (indexPath.row == 0 && indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1)
    {
        cell.top    = YES;
        cell.bottom = YES;
    }
    // first cell - must be rounded on top
    else if (indexPath.row == 0)
    {
        cell.top    = YES;
        cell.bottom = NO;
    }
    // last cell - must be rounded on bottom
    else if (indexPath.row == [tableView numberOfRowsInSection:indexPath.section]-1)
    {
        cell.top    = NO;
        cell.bottom = YES;
    }
    else
    {
        cell.top    = NO;
        cell.top    = NO;
    }
    
    return cell;
}

그리고 짜잔-섹션에 둥근 모서리와 테두리가 있습니다.

도움이 되었기를 바랍니다!

추신 : 원본 코드에서 몇 가지 버그를 발견했을 때 몇 가지 편집을했습니다. 주로 모든 경우에 모든 값을 설정하지 않았기 때문에 셀을 재사용 할 때 매우 놀라운 효과가 발생했습니다. :)

신속한 4 섹션 헤더도 포함하려면 아래에서 시도하십시오.

cornerLayerWidth를 전역 변수로 선언

var cornerLayerWidth : CGFloat = 0.0

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    let cornerRadius: CGFloat = 10
    cell.backgroundColor = .clear

    let layer = CAShapeLayer()
    let pathRef = CGMutablePath()
    let bounds = cell.bounds.insetBy(dx: 0, dy: 0)
    cornerLayerWidth = bounds.width
    var addLine = false



    if indexPath.row == 0 && indexPath.row == tableView.numberOfRows(inSection: indexPath.section) - 1 {
        pathRef.__addRoundedRect(transform: nil, rect: bounds, cornerWidth: cornerRadius, cornerHeight: cornerRadius)
    }
    else if indexPath.row == 0 {


    }
    else if indexPath.row == tableView.numberOfRows(inSection: indexPath.section) - 1 {
        pathRef.move(to: .init(x: bounds.minX, y: bounds.minY))
        pathRef.addArc(tangent1End: .init(x: bounds.minX, y: bounds.maxY), tangent2End: .init(x: bounds.midX, y: bounds.maxY), radius: cornerRadius)
        pathRef.addArc(tangent1End: .init(x: bounds.maxX, y: bounds.maxY), tangent2End: .init(x: bounds.maxX, y: bounds.midY), radius: cornerRadius)
        pathRef.addLine(to: .init(x: bounds.maxX, y: bounds.minY))
    } else {
        pathRef.addRect(bounds)
        addLine = true
    }

    layer.path = pathRef
    layer.fillColor = UIColor(white: 1, alpha: 1).cgColor

    if (addLine == true) {
        let lineLayer = CALayer()
        let lineHeight = 1.0 / UIScreen.main.scale
        lineLayer.frame = CGRect(x: bounds.minX, y: bounds.size.height - lineHeight, width: bounds.size.width , height: lineHeight)
        lineLayer.backgroundColor = tableView.separatorColor?.cgColor
        layer.addSublayer(lineLayer)
    }

    let testView = UIView(frame: bounds)
    testView.layer.insertSublayer(layer, at: 0)
    testView.backgroundColor = .clear
    cell.backgroundView = testView
}

과

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

    let cell = tableView.dequeueReusableCell(withIdentifier: "eMPOIListHeaderViewCell") as! eMPOIListHeaderViewCell

    let cornerRadius: CGFloat = 10

    let layer = CAShapeLayer()
    let pathRef = CGMutablePath()
    let bounds =  CGRect(x: 0, y: 0, width: cornerLayerWidth, height: 50)//cell.bounds.insetBy(dx: 0, dy: 0)

    pathRef.__addRoundedRect(transform: nil, rect: bounds, cornerWidth: cornerRadius, cornerHeight: cornerRadius)

    pathRef.move(to: .init(x: bounds.minX, y: bounds.maxY))
    pathRef.addArc(tangent1End: .init(x: bounds.minX, y: bounds.minY), tangent2End: .init(x: bounds.midX, y: bounds.minY), radius: cornerRadius)
    pathRef.addArc(tangent1End: .init(x: bounds.maxX, y: bounds.minY), tangent2End: .init(x: bounds.maxX, y: bounds.midY), radius: cornerRadius)
    pathRef.addLine(to: .init(x: bounds.maxX, y: bounds.maxY))



    layer.path = pathRef
    layer.fillColor = UIColor(white: 1, alpha: 1).cgColor

         let lineLayer = CALayer()
        let lineHeight = 1.0 / UIScreen.main.scale
        lineLayer.frame = CGRect(x: bounds.minX, y: bounds.size.height - lineHeight, width: bounds.size.width , height: lineHeight)
        lineLayer.backgroundColor = tableView.separatorColor?.cgColor
        layer.addSublayer(lineLayer)

    let testView = UIView(frame: bounds)
    testView.layer.insertSublayer(layer, at: 0)
    testView.backgroundColor = .clear

    cell.backgroundView = testView


    return cell

}

Swift 4.2에서 :

class MyCell: UITableViewCell {

var top = false
var bottom = false

override func layoutSubviews() {
    super.layoutSubviews()

    if top && bottom {
        layer.cornerRadius = 10
        layer.masksToBounds = true
        return
    }

    let shape = CAShapeLayer()
    let rect = CGRect(x: 0, y: 0, width: bounds.width, height: bounds.size.height)
    let corners: UIRectCorner = self.top ? [.topLeft, .topRight] : [.bottomRight, .bottomLeft]

    shape.path = UIBezierPath(roundedRect: rect, byRoundingCorners: corners, cornerRadii: CGSize(width: 10, height: 10)).cgPath
    layer.mask = shape
    layer.masksToBounds = true
  }
}

쓰다:

셀이 그룹의 첫 번째 셀이면을 설정 top = True하고 마지막 셀이면을 bottom = true설정하고 그룹의 유일한 셀이면을 모두로 설정합니다 true.

다소 반올림하려면 라디오를 10에서 다른 값으로 변경하십시오.

이 코드는 단일 셀 대신 전체 테이블보기에 대해 둥근 모서리를 설정합니다.

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];

그리고 cellForRow에서 각 셀의 배경색을 지 웁니다.

cell.backgroundColor=[UIColor clearColor];

이를 추가하여 tableview에서 맨 위 줄을 제거하십시오. self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
