ios - 应用程序不会填满设备屏幕，启动屏幕也不会自动旋转

Question

我有两个问题，我怀疑它们是相互关联的。

我有一个支持两种横向方向的通用应用程序。我的应用程序启动(带有界面构建器启动屏幕)，然后显示 SKScene。我有三个大问题。

1. 在 iPad 上，并且仅在 iPad(iOS 8 或 9)上，当应用程序加载时，所有图像都会丢失，只留下文本。此外，启动屏幕的显示区域比实际设备显示屏小约一厘米。这在 iPhone 上不是问题
2. 在 iPad 上，并且出于某种原因仅在 iPad(iOS 8 或 9)上，整个应用程序周围都带有边框。我的应用程序占用的屏幕区域小于实际设备。这在 iPhone 上不是问题。
3. 我的应用在“shouldAutoRotate()”函数中设置为自动旋转。但是我无法让启动屏幕以正确的方向启动。

我最近做的一些事情可能触发了这个: 添加了结构崩溃报告 添加了自动旋转

我在 iPhone 6 Plus 上遇到了类似的问题。原因是缺少加载该设备显示尺寸的图像。检查您是否有所有所需尺寸和方向的加载图像。正如您在图片中看到的，Xcode 会告诉您特定图像的大小。希望这会解决您的问题。
