根据像this或this这样的引用，我认为风景上的iPhone 7 Plus应该具有常规的大小级别。
这是当前视图控制器中的代码，按照this reference:
- (void) traitCollectionDidChange: (UITraitCollection *) previousTraitCollection {
[super traitCollectionDidChange: previousTraitCollection];
NSLog(@"current trait collection: %@",self.traitCollection);
NSLog(@"previous trait collection: %@", previousTraitCollection);
}
这是在iPhone 7 Plus上从纵向转到横向时控制台上的输出:
current trait collection: <UITraitCollection: 0x1c44efd00; _UITraitNameUserInterfaceIdiom = Phone, _UITraitNameDisplayScale = 3.000000, _UITraitNameDisplayGamut = P3, _UITraitNameHorizontalSizeClass = Compact, _UITraitNameVerticalSizeClass = Compact, _UITraitNameTouchLevel = 0, _UITraitNameInteractionModel = 1, _UITraitNameUserInterfaceStyle = 1, _UITraitNameUserInterfaceLayoutDirection = 0, _UITraitNameForceTouchCapability = 2, _UITraitNamePreferredContentSizeCategory = UICTContentSizeCategoryL, _UITraitNameDisplayCornerRadius = 0.000000>
previous trait collection: <UITraitCollection: 0x1c02fa900; _UITraitNameUserInterfaceIdiom = Phone, _UITraitNameDisplayScale = 3.000000, _UITraitNameDisplayGamut = P3, _UITraitNameHorizontalSizeClass = Compact, _UITraitNameVerticalSizeClass = Regular, _UITraitNameTouchLevel = 0, _UITraitNameInteractionModel = 1, _UITraitNameUserInterfaceStyle = 1, _UITraitNameUserInterfaceLayoutDirection = 0, _UITraitNameForceTouchCapability = 2, _UITraitNamePreferredContentSizeCategory = UICTContentSizeCategoryL, _UITraitNameDisplayCornerRadius = 0.000000>
水平尺寸类保持紧凑，我希望从紧凑型变为常规型。
使用iOS 11.1.2和Xcode 9.1
最佳答案
您是否已打开设备的显示缩放？

在“标准”模式下，横向中的水平尺寸类别将为“常规”。在“缩放”模式下，它将是紧凑的。
关于ios - iPhone 7 Plus的水平尺寸等级仍然紧凑吗？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/47639547/
