Question

我试图在iOS 7中构建自定义转换。转换很顺利，但是当转换上下文完成转换时，模态屏幕完全从视图中消失。我已经完成了几个教程，但我不知道自己做错了什么。另外，如果我没有打电话给＃34;完成过渡＆＃34;然后视图停留，但不会收到任何触摸事件。我检查了Reveal App，没有看到它的顶部。有什么想法吗？

以下是我启动转换的方法

- (IBAction)settingsButtonClicked:(id)sender
{
    UINavigationController *navigationController =[[self storyboard] instantiateViewControllerWithIdentifier:@"SettingsNavigationViewController"];
    navigationController.transitioningDelegate = self;
    [self presentViewController:navigationController animated:YES completion:nil];
}

以下是自定义转换的代码：

- (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext
{
    UIViewController *fromViewController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
    UIViewController *toViewController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];

    UIView *containerView = [transitionContext containerView];
    [containerView addSubview:toViewController.view];

    CGRect sourceRect = [transitionContext initialFrameForViewController:fromViewController];
    CGRect initialTargetFrame = [transitionContext initialFrameForViewController:toViewController];

    CGRect initialFrame = CGRectMake(sourceRect.size.width + initialTargetFrame.size.width, 0, initialTargetFrame.size.width, initialTargetFrame.size.height);
    CGPoint destinationPoint = CGPointMake(sourceRect.size.width - 500, 0);

    CGAffineTransform translate = CGAffineTransformMakeTranslation(initialFrame.origin.x, initialFrame.origin.y);
    toViewController.view.transform = translate;



    [UIView animateWithDuration:PRESENT_DURATION delay:0 options:UIViewAnimationOptionCurveEaseOut
                     animations:^{
                         toViewController.view.transform = CGAffineTransformMakeTranslation(destinationPoint.x, destinationPoint.y);
                     }
                     completion:^(BOOL completed) {
                         if (completed) {

                             [transitionContext completeTransition:!transitionContext.transitionWasCancelled];
                         }

                     }];
}

所以我发现了我做错了什么。当我应该在导航控制器本身上设置它时，我正在将视频控制器上的modalPresentationStyle更改为自定义在弹出到导航控制器上的视图控制器上。我将此行添加到上面的settingsButtonClicked方法中，并且它正常工作。

navigationController.modalPresentationStyle = UIModalPresentationCustom;

模态视图使用自定义过渡时消失
