横向旋转后推送方向变化答案

【问题标题】：Push direction changes after landscape rotation横向旋转后推送方向变化

【问题描述】：

我只有横向应用程序。导航效果很好：当我推送一个新视图时，它会通过从左向右滑动来加载和显示。当它被卸载时，从右向左滑动。但是，当我旋转设备时，情况发生了变化，现在推动是从右到左。为了面对 iOS 7 中不处理旧式推送而不避免滑动视图奇怪的懒惰出现的错误，我使用此代码

- (void)pushViewControllerRetro:(UIViewController *)viewController {
    CATransition *transition = [CATransition animation];
    transition.duration = 0.3;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype = kCATransitionFromBottom;
    [self.view.layer addAnimation:transition forKey:nil];

    [self pushViewController:viewController animated:NO];
}

- (void)popViewControllerRetro {
    CATransition *transition = [CATransition animation];
    transition.duration = 0.3;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype = kCATransitionFromTop;
    [self.view.layer addAnimation:transition forKey:nil];

    [self popViewControllerAnimated:NO];
}

为什么？

【问题讨论】：

你的意思是如果你旋转180度？

【解决方案1】：

当您将设备旋转 180 度时，您会从 LandscapeLeft 转到 LandscapeRight ... 左转右，反之亦然。使用 deviceRotation 来定义你的自定义转换

例如第一种情况

transition.type = [UIDevice currentDevice]. orientation == UIDeviceRotationLandscapeLeft ? kCATransitionFromRight : kCATransitionFromLeft;

【讨论】：

好的，抱歉我抄错了代码。看我的编辑。你的解决方案（你的意思是 UIDeviceOrientationLandscapeLeft，你不是吗）禁用了推动的动画......

【解决方案2】：

这是正确的解决方案

- (void)pushViewControllerRetro:(UIViewController *)viewController {
    CATransition *transition = [CATransition animation];
    transition.duration = 0.3;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;


     transition.subtype = [UIDevice currentDevice].orientation == UIDeviceOrientationLandscapeRight ?kCATransitionFromBottom : kCATransitionFromTop;
    [self.view.layer addAnimation:transition forKey:nil];

    [self pushViewController:viewController animated:NO];

}

- (void)popViewControllerRetro {
    CATransition *transition = [CATransition animation];
    transition.duration = 0.3;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype = [UIDevice currentDevice].orientation == UIDeviceOrientationLandscapeRight ?kCATransitionFromTop : kCATransitionFromBottom;

    [self.view.layer addAnimation:transition forKey:nil];

    [self popViewControllerAnimated:NO];
}
