iOS的7变化pushviewcontroller动画方向 [英] iOS 7 change pushviewcontroller animation direction

问题描述

当我推的ViewController动画始终是从右到左。我想该动画改变到从左到右的倒数。
我已经试过这code，但不工作。动画仍然是从右到左。我怎么能简单地和正确地achive呢？需要帮助，请。先谢谢了。

  //不工作
myViewController * mController = [self.storyboard instantiateViewControllerWithIdentifier：@myViewController];CATransition *跃迁= [CATransition动画]
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName：kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;[self.view.layer addAnimation：过渡forKey：无];[self.navigationController pushViewController：mController动画：是];
 

解决方案

您实际上这样做是正确的，但据我从你的code明白了，你是不是覆盖方法：

   - （无效）pushViewController：（UIViewController的*）的viewController动画：（BOOL）动画
 

所以，你需要从的UINavigationController 继承并覆盖上述方法。

下面是我如何做到这一点（推+ POP）：

按

   - （无效）pushViewController：（UIViewController的*）的viewController动画：（BOOL）动画{
    UIView的* theWindow = self.view;
    如果（动画）{
        CATransition *动画= [CATransition动画]
        [动画setDuration：0.45f];
        [动画的setType：kCATransitionPush];
        [动画setSubtype：kCATransitionFromLeft];
        [动画setTimingFunction：[CAMediaTimingFunction functionWithName：kCAMediaTimingFunctionEaseOut]];
        [theWindow层] addAnimation：动画forKey：@];
    }    //确保我们通过超级动画：NO，否则我们会得到我们两个
    //动画和超级动画
    [超级pushViewController：动画的viewController：NO];    [个体经营swapButtonsForViewController：的viewController];}
 

流行：

   - （UIViewController的*）popViewControllerAnimated：动画（BOOL）{
    UIView的* theWindow = self.view;
    如果（动画）{
        CATransition *动画= [CATransition动画]
        [动画setDuration：0.45f];
        [动画的setType：kCATransitionPush];
        [动画setSubtype：kCATransitionFromRight];
        [动画setTimingFunction：[CAMediaTimingFunction functionWithName：kCAMediaTimingFunctionEaseOut]];
        [theWindow层] addAnimation：动画forKey：@];
    }
    返回[超级popViewControllerAnimated：NO];
}
 

When i push a viewcontroller the animation is always from right to left. I want to change that animation to the inverse left to right. I have tried this code but doesnt work. The animation is still from right to left. How can i achive this simply and correctly? Need help please. Thanks in advance.

//NOT WORKING
myViewController *mController = [self.storyboard instantiateViewControllerWithIdentifier:@"myViewController"];

CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;

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

[self.navigationController pushViewController:mController animated:YES];

解决方案

You are actually doing it right, but as far as I understand from your code, you are not overriding the method:

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated

So, you need to inherit from UINavigationController and override the above method.

Here's how I do it (push + pop):

Push:

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{
    UIView *theWindow = self.view ;
    if( animated ) {
        CATransition *animation = [CATransition animation];
        [animation setDuration:0.45f];
        [animation setType:kCATransitionPush];
        [animation setSubtype:kCATransitionFromLeft];
        [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut]];
        [[theWindow layer] addAnimation:animation forKey:@""];
    }

    //make sure we pass the super "animated:NO" or we will get both our
    //animation and the super's animation
    [super pushViewController:viewController animated:NO];

    [self swapButtonsForViewController:viewController];

}

Pop :

- (UIViewController *)popViewControllerAnimated:(BOOL)animated {
    UIView *theWindow = self.view ;
    if( animated ) {
        CATransition *animation = [CATransition animation];
        [animation setDuration:0.45f];
        [animation setType:kCATransitionPush];
        [animation setSubtype:kCATransitionFromRight];
        [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut]];
        [[theWindow layer] addAnimation:animation forKey:@""];
    }
    return [super popViewControllerAnimated:NO];
}
