ios 子视图超出父视图
Safari’s Split View is a new feature in iOS 10 that allows you to view two Safari windows side-by-side on your iPad. It’s similar to the Split View feature that was added to iOS 9, but specifically for Safari.
Safari的Split View是iOS 10中的一项新功能，可让您在iPad上并排查看两个Safari窗口。 它类似于iOS 9中添加的“ 拆分视图”功能 ，但专门用于Safari。
NOTE: This feature only works on iPad, not iPhone, and it only works in landscape mode.
注意：此功能仅适用于iPad，不适用于iPhone，并且仅适用于横向模式。
One major difference between iOS 9’s Split View and Safari’s Split View in iOS 10 is that you can’t adjust the size of the two Safari windows. Each window takes up exactly half the screen and that can’t be changed. However, Split View in Safari is still a useful feature and we’ll show you how to invoke and use it.
iOS 9的分割视图和Safari的iOS 10的分割视图之间的主要区别在于，您无法调整两个Safari窗口的大小。 每个窗口正好占据屏幕的一半，并且无法更改。 但是，Safari中的Split View仍然是有用的功能，我们将向您展示如何调用和使用它。
There are two ways you can invoke Split View in Safari. First, tap and hold on a link on a webpage and then select “Open in Split View” from the popup menu.
您可以通过两种方式在Safari中调用“拆分视图”。 首先，点击并按住网页上的链接，然后从弹出菜单中选择“在拆分视图中打开”。
The second method works if you have multiple tabs open. You can drag a tab to the right until it separates from the main window. Then, lift your finger from the screen.
如果您打开了多个选项卡，则第二种方法有效。 您可以将选项卡向右拖动，直到与主窗口分离。 然后，从屏幕上抬起手指。
Using either method will result in two Safari windows, each with its own address bar, tab interface, and toolbar (at the bottom rather than the top). Each window operates separately, like two apps, but it’s still one app. For example, you can tap the tabs button on the toolbar at the bottom of one of the windows to manage the tabs in that window.
使用这两种方法都将导致两个Safari窗口，每个窗口都有自己的地址栏，选项卡界面和工具栏(在底部而不是顶部)。 每个窗口都单独运行，就像两个应用程序一样，但仍然是一个应用程序。 例如，您可以点击其中一个窗口底部工具栏上的选项卡按钮，以管理该窗口中的选项卡。
The tab view interface displays in that Safari window, and you can tap the plus icon to add a new tab, tap “Private” to convert that window to private browsing mode, close any tab, or close all tabs at once.
选项卡视图界面显示在该Safari窗口中，您可以点击加号图标以添加新的选项卡，点击“私人”以将该窗口转换为私有浏览模式，关闭任何选项卡，或立即关闭所有选项卡 。
Once you’re in Split View mode, you can open links on one Safari window in the other window. To do this, tap and hold on a link and select “Open on Other Side” from the popup menu.
进入“拆分视图”模式后，您可以在另一个Safari窗口中打开链接。 为此，请点击并按住链接，然后从弹出菜单中选择“在另一侧打开”。
In our example, the link in the left window is opened on a new tab in the right window.
在我们的示例中，左侧窗口中的链接在右侧窗口中的新选项卡上打开。
In Split View, you can move tabs between the windows by dragging a tab from one window to the other. When you move a tab from one window to the other, the tab’s history is retained, allowing you to use the forward and back buttons to navigate through the history of that tab.
在拆分视图中，可以通过将选项卡从一个窗口拖动到另一个窗口来在窗口之间移动选项卡。 将选项卡从一个窗口移动到另一个窗口时，将保留该选项卡的历史记录，从而允许您使用前进和后退按钮浏览该选项卡的历史记录。
NOTE: You can only drag tabs between the two Safari windows when they share the same status, meaning you can only drag tabs between two private windows or two regular windows. If you have one private window and one regular window, you cannot drag tabs between them. However, you can use the “Open on Other Side” option to open a link on a private window in the other regular window, or vice versa. The new tab opens in whichever mode the receiving window is in.
注意：您只能在两个Safari窗口共享相同状态时在两个Safari窗口之间拖动选项卡，这意味着您只能在两个私有窗口或两个常规窗口之间拖动选项卡。 如果您有一个私有窗口和一个常规窗口，则不能在它们之间拖动选项卡。 但是，您可以使用“在另一侧打开”选项在另一个常规窗口的私有窗口上打开链接，反之亦然。 无论接收窗口处于哪种模式，都会打开新选项卡。
When you’re in Split View, you can go back to one Safari window in a couple of ways. You can drag tabs one at a time from one window to the other. When you drag the last open tab in one window to the other, Safari returns to single window mode automatically.
在“拆分视图”中，可以通过两种方式返回一个Safari窗口。 您可以一次将一个标签从一个窗口拖到另一个窗口。 当您将一个窗口中的最后一个打开的选项卡拖到另一个窗口时，Safari会自动返回单窗口模式。
A quicker way to go back to a single Safari window is to tap and hold on the tabs button in either Safari window. Select “Merge All Tabs” from the popup menu.
返回单个Safari窗口的更快方法是点击并按住任一Safari窗口中的选项卡按钮。 从弹出菜单中选择“合并所有选项卡”。
All your tabs from both windows are merged into a single Safari window, and the toolbar moves back to the top.
两个窗口中的所有选项卡都合并到一个Safari窗口中，工具栏将移回顶部。
When you go back to the Home screen from Safari, or even force close Safari, the app will remember where you left off and reopen in Split View along with all the tabs you had open in the status (private/regular) you had set.
当您从Safari返回主屏幕，甚至强制关闭Safari时，该应用程序都会记住您离开的位置并在“拆分视图”中重新打开，并以您已设置的状态(私有/常规)打开所有选项卡。
