在 iOS 8 中,界面旋转的方法是 已弃用.这包括:
In iOS 8, the methods for interface rotation are deprecated. This includes:
willRotateToInterfaceOrientation:duration:
didRotateFromInterfaceOrientation:
willAnimateRotationToInterfaceOrientation:duration:
替换方法包括:
willTransitionToTraitCollection:withTransitionCoordinator:
viewWillTransitionToSize:withTransitionCoordinator:
如果未实现新的旋转方法,并且项目是使用 iOS 8 SDK 编译的,则视图控制器 - 将不会接收调用- 对已弃用的旋转方法的调用.
If the new rotation methods are not implemented, and a project is compiled with the iOS 8 SDK, the view controllers -will not receive calls- to the deprecated rotation methods.
我担心的是:AppStore 中已经使用 iOS 7 SDK 构建的应用会发生什么情况?是否仍会在 iOS 8 设备上调用已弃用的轮换方法?
仍会调用旋转方法,但在 iOS 8 中存在一些更改/问题/错误.
The rotation methods are still called, but there exist some changes/issues/bugs in iOS 8.
另外,UIScreen
现在是面向界面的
Also UIScreen
is now interface oriented
iOS 8 SDK 中不推荐使用旋转方法.这对使用 iOS 7 SDK 构建的应用完全没有影响,即使在 iOS 8 和未来的几个 iOS 版本中运行也是如此.
The rotation methods are deprecated in the iOS 8 SDK. This will have no effect at all on apps built with the iOS 7 SDK, even running in iOS 8 and probably several future versions of iOS.
例如,UIButton
的 font
属性自 iOS 3.0 以来已被弃用,但在 iOS 7.0 中仍然可用.
As an example, the font
property of UIButton
has been deprecated since iOS 3.0 and is still available in iOS 7.0.
