iOS 9 UITableView分隔符插入（显着的左边距） [英] iOS 9 UITableView separators insets (significant left margin)

问题描述

UITableViewCell 在 iOS 9上的 UITableView 之间的分隔符有问题/ code>。它们具有显着的左边距。我已经有了删除由 iOS 8 引入的间距的代码，但它不适用于 iOS 9 。看起来他们添加了别的东西。我想它可能与 layoutMarginsGuide 但我还没想出来。有没有人有类似的问题并找到解决方案？

I have a problem with separators between UITableViewCells in UITableView on iOS 9. They have the significant left margin. I already have code for removing spacing introduced by iOS 8 but it doesn't work with iOS 9. It looks like they added something else. I suppose it might be connected with layoutMarginsGuide but I haven't figured it out yet. Does anyone had a similar problem and found out the solution?

推荐答案

好的，我找到了解决方案。唯一需要的是设置 UITableView 的呈现实例，该标志 cellLayoutMarginsFollowReadableWidth

Okay, I have found out the solution. The only thing required for that is to set on the presenting instance of UITableView that flag cellLayoutMarginsFollowReadableWidth

myTableView.cellLayoutMarginsFollowReadableWidth = NO;

我想在文档中找到一些参考文献，但它看起来还没准备好，仅在差异页面上提及。

I wanted to find some reference in the documentation but it looks like it is not ready yet, only mentioned on diff page.

由于该标志是在iOS 9中引入的，为了向后兼容，您应该在尝试设置之前添加一个检查：

As the flag was introduced in iOS 9 for the backward compatibility you should add a check before trying to set it:

if([myTableView respondsToSelector:@selector(setCellLayoutMarginsFollowReadableWidth:)])
{
    myTableView.cellLayoutMarginsFollowReadableWidth = NO;
}

对于 Swift 2.0 您可以使用 #available 来检查iOS版本。

For Swift 2.0 you can use #available to check iOS version.

if #available(iOS 9, *) {
    myTableView.cellLayoutMarginsFollowReadableWidth = false
}

此外，您需要使用 Xcode 7 或更高版本进行编译。

Moreover you need to compile it with Xcode 7 or above.

编辑

请记住，如果您的分隔符在iOS 8中看起来很好，这是唯一需要的修复，否则您需要更改一点。您可以在SO上找到有关如何执行此操作的信息。

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.
