iOS 9 UITableView 分隔符插入(显着的左边距)

问题描述

我在 iOS 9 上的 UITableView 中的 UITableViewCell 之间的分隔符有问题.他们有显着的左边距.我已经有删除 iOS 8 引入的间距的代码，但它不适用于 iOS 9.看起来他们添加了其他东西.我想它可能与 layoutMarginsGuide 但我还没弄明白.有没有人遇到过类似的问题并找到了解决方案?

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.唯一需要的是在 UITableView 的呈现实例上设置标志 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，但看起来还没有准备好，仅在差异页面提及.

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:

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 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.
