iPhone 6s Plus在横向上具有紧凑的水平尺寸等级 [英] iPhone 6s Plus has Compact horizontal size class in landscape orientation

问题描述

我有一个iPhone 6s Plus，我有一个同时支持纵向和横向的应用程序.

I have an iPhone 6s Plus, and I have an app that supports both Portrait and Landscape orientations.

旋转设备并读取属性mainViewController.traitCollection.horizo​​ntalSizeClass时-它始终等于 UIUserInterfaceSizeClassCompact .

When I rotate my device and read the property mainViewController.traitCollection.horizontalSizeClass - it always equals UIUserInterfaceSizeClassCompact.

告诉我们所有5.5英寸的iPhone在横向都具有常规的水平尺寸级别，但我的设备没有！

tell that all 5.5-inch iPhones have Regular horizontal size class in the landscape orientation, but my device doesn't!!!

在 iPhone 6 Plus模拟器或 iPhone 6s Plus模拟器上启动相同的应用程序会得出不同的结果:在这种情况下，水平尺寸类别在横向上是常规的，就像这样是预期的.

Launching the same app on the iPhone 6 Plus Simulator or the iPhone 6s Plus Simulator gives different results: in this case horizontal size class is Regular in landscape, like it was expected.

我想知道，那会是什么?有任何猜想吗?

I wonder, what could it be? Any guesses?

推荐答案

iPhone 6和6 plus设备具有缩放"显示模式，该模式使逻辑屏幕尺寸变小，在设置->显示和亮度->显示缩放下

iPhone 6 and 6 plus devices have a "Zoomed" display mode which makes the logical screen size appear smaller, under settings -> Display and Brightness -> Display Zoom

这会在横向模式下影响6尺寸以上设备的特征收集.这也是您在计算尺寸等时不应该执行设备检查代码的原因.

This affects the trait collection of a 6 plus sized device when in landscape mode. It's also a reason you shouldn't do device checking code when calculating sizes etc.
