使用iOS 7以2x模式在iPad上启动应用程序 [英] Launch app on iPad in 2x mode with iOS 7

问题描述

在iOS 7之前，在iPad上打开的iPhone应用程序曾经以2x模式启动。 iOS 7似乎迫使所有应用程序（即使它们不是为iPad设计）以1x模式启动。我们如何强制我们的应用程序在iPad上使用iOS 7以2x模式启动？

Before iOS 7, iPhone apps that opened on iPads used to launch in 2x mode. iOS 7 seems to force all apps, even if they weren't designed for the iPad, to launch in 1x mode. How can we force our app to launch in 2x mode on iPads using iOS 7?

推荐答案

现在运行iOS 7的iPad上的iPhone应用程序始终作为Retina iPhone应用程序打开，而在iOS 6上，它们在非视网膜iPad上作为非视网膜应用打开。

iPhone apps on iPads running iOS 7 now always open as a Retina iPhone app, while on iOS 6 they opened as a non-retina apps on non-retina iPads.

在Retina iPad上（iPad 3和4）应用程序可以以1x（iPhone大小）或2x（尽可能多地占用iPad屏幕）显示，并且可以切换。

On Retina iPads (iPad 3 and 4) the apps may display in 1x (iPhone sized) or 2x (taking as much of the iPad screen as possible) and may be toggled.

在非Retina iPad上（iPad） 2和iPad mini）应用程序仅以2x模式显示，无法切换。这是因为非视网膜iPad没有足够的像素密度来显示正常尺寸的视网膜iPhone应用程序。

On non-Retina iPads (iPad 2 and iPad mini) the apps only display in 2x mode and cannot be toggled. This is because the non-retina iPads do not have enough pixel density to display the retina iPhone apps at the "normal" size.

此行为由操作系统和您的应用无法更改。

This behavior is determined by the OS and cannot be changed by your app.
