不推荐使用旋转方法，相当于'didRotateFromInterfaceOrientation'？ [英] Rotation methods deprecated, equivalent of 'didRotateFromInterfaceOrientation'?

问题描述

我正在尝试实现iOS 8中引入的新 viewWillTransitionToSize 方法（所有其他轮换方法都已弃用）。我想知道现在是什么等于 didRotateFromInterfaceOrientation ，因为我们需要执行许多清理任务，我看不到我们可以阻止的块分配给 UIViewControllerTransitionCoordinator ，以便在转换到新大小时完成调用。谢谢。

I'm trying to implement the new viewWillTransitionToSize method which has been introduced in iOS 8 (all other rotation methods have been deprecated). I'd like to know what the equivalent of didRotateFromInterfaceOrientation is now as there are a number of clean up tasks we need to perform and I can't see a block that we can assign to UIViewControllerTransitionCoordinator in order to be called when 'transition' to a new size finishes. Thanks.

推荐答案

好的发现它，只需要使用 animateAlongsideTransition：完成： UIViewControllerTransitionCoordinator 的$ c>方法。

Okay found it, just have to use the animateAlongsideTransition:completion: method on the passed UIViewControllerTransitionCoordinator.

- (void)viewWillTransitionToSize:(CGSize)size withTransitionCoordinator:(id<UIViewControllerTransitionCoordinator>)coordinator
{   
    [coordinator animateAlongsideTransition:^(id<UIViewControllerTransitionCoordinatorContext> context)
    {
        UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
        // do whatever
    } completion:^(id<UIViewControllerTransitionCoordinatorContext> context)
    { 

    }];

    [super viewWillTransitionToSize:size withTransitionCoordinator:coordinator];
}
