为什么 Xcode 中 iPhone6 的 Launch Image 不显示全屏显示？答案

【问题标题】：Why doesn't view show full screen with Launch Image in iPhone6 in Xcode?为什么 Xcode 中 iPhone6 的 Launch Image 不显示全屏显示？
【发布时间】：2017-03-23 03:32:27
【问题描述】：

我使用启动屏幕 (launchscreen.storyboard) 并在 ViewControllers 和 launchscreen.storyboard 中选中“使用自动布局”。

但是当我在 General -> App Icons and Launch Images 中设置 Launch Screen File 时，ViewController 中的视图（UIView 子类）在 iPhoneSE 和 6 中不显示全屏。（ViewController 中的背景图像显示全屏。）

删除应用程序图标和启动图像中的“启动屏幕文件”，视图显示全屏。（我尝试将 xib 文件用于launchImage，但它是一样的。）

我该如何解决？

【解决方案1】：

这通常发生在您的启动图像不正确时。 iOS 根据启动图像的大小来确定屏幕大小。我在 iPhone 6 上遇到了类似的问题，我通过在应用程序中（而不是在 images.Assets 中）添加启动图像为 png 并在 info.plist 中添加 UILaunchImages 字典来解决该问题。但这里也为 iPhone 6 使用横向图像。这是 info.plist 的源代码。但我们确信所有启动图像的大小都是正确的。
