Remove separator line for only one cell
提问by Jessica
I'm trying to remove the separator for one UITableViewCell. I did the following:
我正在尝试删除 one 的分隔符UITableViewCell。我做了以下事情：
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell;
cell = [super tableView:tableView cellForRowAtIndexPath:indexPath];
if (indexPath.row == 1)
cell.separatorInset = UIEdgeInsetsZero;
return cell;
}
(It's static cells.) When I run the app. The separator line is still there. How can I remove the separator line for one cell?
（它是static cells。）当我运行应用程序时。分隔线仍然存在。如何删除一个分隔线cell？

On iOS 8 you need to use:
在 iOS 8 上，您需要使用：
cell.layoutMargins = UIEdgeInsetsZero
If you want to be compatible with iOS 7 as well you should do following:
如果您还想与 iOS 7 兼容，您应该执行以下操作：
if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
[cell setSeparatorInset:UIEdgeInsetsZero];
}
if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
[cell setLayoutMargins:UIEdgeInsetsZero];
}
ADD:If previous didn't work - use this. (from answer below)
添加：如果以前不起作用 - 使用这个。（来自下面的回答）
cell.separatorInset = UIEdgeInsetsMake(0, CGFLOAT_MAX, 0, 0);
If none of above worked, you can do:
如果以上都不起作用，您可以执行以下操作：
self.tableView.separatorColor = [UIColor clearColor];
self.tableView.separatorColor = [UIColor clearColor];
but this will leave 1 pixel empty space, not really removing a line, more making it transparent.
但这会留下 1 个像素的空白空间，而不是真正删除一条线，而是使其透明。

You can just visually hide separator through separatorInsetproperty:
您可以通过separatorInset属性直观地隐藏分隔符：
tableViewCell.separatorInset = UIEdgeInsets(top: 0, left: 10000, bottom: 0, right: 0)

Assign next values for specific cell you need for customization.
为自定义所需的特定单元格分配下一个值。
cell.separatorInset = UIEdgeInsetsMake(0, 0, 0, .greatestFiniteMagnitude)
cell.directionalLayoutMargins = .zero
回答by Kostas Tsoleridis
If you want to hide the separation line for only a specific type of cell, you can use the following code:
如果只想隐藏特定类型单元格的分隔线，可以使用以下代码：
override func layoutSubviews() {
super.layoutSubviews()
subviews.forEach { (view) in
if view.dynamicType.description() == "_UITableViewCellSeparatorView" {
view.hidden = true
}
}
}
Write this code in the cell (it must be a subclass of UITableViewCell) for which you do not want a separation line to appear.
在UITableViewCell不希望出现分隔线的单元格（它必须是 的子类）中编写此代码。

Just add following to the cell you don't want separator (swift 3) :
只需将以下内容添加到您不需要分隔符的单元格中（swift 3）：
override func awakeFromNib() {
super.awakeFromNib()
// remove separator
self.separatorInset = UIEdgeInsetsMake(0, 1000, 0, 0)
}

cell.separatorInset = UIEdgeInsetsMake(0.0 , cell.bounds.size.width , 0.0, -cell.bounds.size.width)

For those people struggling with this for iOS 9 the solution is a little different than the answers already given. Here is how I solved it in Swift:
对于那些为 iOS 9 苦苦挣扎的人来说，解决方案与已经给出的答案略有不同。这是我在 Swift 中解决它的方法：
override func viewWillAppear(animated: Bool) {
table.cellLayoutMarginsFollowReadableWidth = false
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if IS_THE_CELL_WITH_NO_SEPARATOR{
cell.separatorInset = UIEdgeInsetsZero
cell.preservesSuperviewLayoutMargins = false
cell.layoutMargins = UIEdgeInsetsZero
}
}
func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
if IS_THE_CELL_WITH_NO_SEPARATOR{
let size = self.view.bounds.size
let rightInset = size.width > size.height ? size.width : size.height
cell.separatorInset = UIEdgeInsetsMake(0, 0, 0, rightInset)
}
}

Another way that is a bit hacky is to create the custom table view cell with a uiView that acts like separator inset. Then, hide and show that when you want to.
另一种有点hacky的方法是使用uiView创建自定义表格视图单元格，其作用类似于分隔符插入。然后，在需要时隐藏并显示。
I created SampleTableViewCell and a nib file with label and separatorLineView
我创建了 SampleTableViewCell 和一个带有标签和 separatorLineView 的 nib 文件
@interface SampleTableViewCell : UITableViewCell
@property (weak, nonatomic) IBOutlet UILabel *titleLabel;
@property (weak, nonatomic) IBOutlet UIView *separatorLineView;
@end
Then, in ViewController Class
然后，在 ViewController 类中
@interface ViewController ()
@property (nonatomic) NSArray *items;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.items = @[@"A", @"B", @"C"];
[self.tableView registerNib:[UINib nibWithNibName:@"SampleTableViewCell" bundle:nil] forCellReuseIdentifier:@"SampleCell"];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
SampleTableViewCell *cell = (SampleTableViewCell *)[tableView dequeueReusableCellWithIdentifier:@"SampleCell" forIndexPath:indexPath];
cell.titleLabel.text = self.items[indexPath.row];
if (indexPath.row == 1) {
cell.separatorLineView.hidden = YES;
} else {
cell.separatorLineView.hidden = NO;
}
return cell;
}
@end

I created a Extension to UITableViewCell, setting separatorInset value brings anchor bugs to me, I'm using Eureka form Pod.
我为 UITableViewCell 创建了一个扩展，设置 separatorInset 值给我带来了锚点错误，我正在使用 Eureka 表单 Pod。
extension UITableViewCell {
func hideSeparator(hide: Bool) {
let subviews = self.subviews
for view in subviews {
if view.classForCoder.description() == "_UITableViewCellSeparatorView" {
view.isHidden = hide
}
}
}
}
