iOS 9 UITableView separators insets (significant left margin)
提问by Julian Król
I have a problem with separators between UITableViewCells in UITableViewon iOS 9. They have the significant left margin. I already have code for removing spacing introduced by iOS 8but it doesn't work with iOS 9. It looks like they added something else. I suppose it might be connected with layoutMarginsGuidebut I haven't figured it out yet. Does anyone had a similar problem and found out the solution?
我对UITableViewCells in UITableViewon之间的分隔符有问题iOS 9。他们有显着的左边距。我已经有删除由 引入的间距的代码，iOS 8但它不适用于iOS 9. 看起来他们添加了其他东西。我想它可能与layoutMarginsGuide 相关，但我还没有弄清楚。有没有人遇到过类似的问题并找到了解决方案？
回答by Julian Król
Okay, I have found out the solution. The only thing required for that is to set on the presenting instance of UITableViewthat flag cellLayoutMarginsFollowReadableWidth
好的，我已经找到了解决方案。唯一需要的是在该UITableView标志的呈现实例上进行设置cellLayoutMarginsFollowReadableWidth
myTableView.cellLayoutMarginsFollowReadableWidth = NO;
I wanted to find some reference in the documentation but it looks like it is not ready yet, only mentioned on diff page.
我想在文档中找到一些参考，但看起来还没有准备好，只在 diff page 上提到。
As the flag was introduced in iOS 9 for the backward compatibility you should add a check before trying to set it:
由于该标志是在 iOS 9 中为了向后兼容性而引入的，因此您应该在尝试设置它之前添加一个检查：
if([myTableView respondsToSelector:@selector(setCellLayoutMarginsFollowReadableWidth:)])
{
myTableView.cellLayoutMarginsFollowReadableWidth = NO;
}
For Swift 2.0you can use #availableto check iOS version.
因为Swift 2.0你可以#available用来检查 iOS 版本。
if #available(iOS 9, *) {
myTableView.cellLayoutMarginsFollowReadableWidth = false
}
Moreover you need to compile it with Xcode 7or above.
此外，您需要使用Xcode 7或以上编译它。
EDIT

Please keep in mind that this is the only required fix if your separators looked "fine" up to iOS 8, otherwise you need to change a bit more. You can find info how to do this already on SO.
请记住，如果您的分隔符在 iOS 8 之前看起来“很好”，这是唯一需要的修复，否则您需要进行更多更改。您可以在 SO 上找到如何执行此操作的信息。

If you want to do it in interface builder. The default separator inset is Automatic. Change it to customby selecting the dropdown.
如果你想在界面构建器中做到这一点。默认的分隔符插入是Automatic. custom通过选择下拉菜单将其更改为。

In viewDidLoad
在视图中加载
tableView.cellLayoutMarginsFollowReadableWidth = false
In UITableViewDelegates
在 UITableViewDelegates 中
func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
if cell.respondsToSelector(Selector("setSeparatorInset:")){
cell.separatorInset = UIEdgeInsetsZero
}
if cell.respondsToSelector(Selector("setPreservesSuperviewLayoutMargins:")) {

if cell.respondsToSelector(Selector("setLayoutMargins:")){
cell.layoutMargins = UIEdgeInsetsZero

Perfect Solution upto iOS 9
iOS 9 的完美解决方案
In viewDidLoad
在视图中加载
- (void)viewDidLoad {
[super viewDidLoad];
//Required for iOS 9
if ([[[UIDevice currentDevice]systemVersion]floatValue] >= 9.0) {
self.testTableView.cellLayoutMarginsFollowReadableWidth = NO;
}
}
In TableViewDelegate methods add following code:
在 TableViewDelegate 方法中添加以下代码：
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
// Remove seperator inset
if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
[cell setSeparatorInset:UIEdgeInsetsZero];
}
// Prevent the cell from inheriting the Table View's margin settings
if ([cell respondsToSelector:@selector(setPreservesSuperviewLayoutMargins:)]) {
[cell setPreservesSuperviewLayoutMargins:NO];
}
// Explictly set your cell's layout margins
if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
[cell setLayoutMargins:UIEdgeInsetsZero];
}
}

Based on different answers here, I am able to remove the gap from separator with these lines of codes in Swift:
根据此处的不同答案，我可以使用 Swift 中的这些代码行消除分隔符中的间隙：
tableView.separatorInset = UIEdgeInsetsZero
tableView.layoutMargins = UIEdgeInsetsZero
cell.separatorInset = UIEdgeInsetsZero
cell.layoutMargins = UIEdgeInsetsZero
But still I am having this small gap before the text:
但是我在文本之前仍然有这个小差距：

This worked perfectly for me in iOS 9.

The accepted answer did not work for me. Until I moved setCellLayoutMarginsFollowReadableWidthBEFORE setLayoutMargins(still needed for iOS 8):
接受的答案对我不起作用。直到我搬家setCellLayoutMarginsFollowReadableWidth之前setLayoutMargins（iOS 8 仍然需要）：
if([_tableView respondsToSelector:@selector(setCellLayoutMarginsFollowReadableWidth:)]) {
_tableView.cellLayoutMarginsFollowReadableWidth = NO;
}
if ([_tableView respondsToSelector:@selector(setLayoutMargins:)]) {
_tableView.layoutMargins = UIEdgeInsetsZero;
}
