ECSlidingViewController缩放动画

Question

我正在尝试在ECSLidingViewController2中设置我与缩放动画的滑动过渡。

就像在TransitionFun示例(https://github.com/ECSlidingViewController/ECSlidingViewController/blob/master/Examples/TransitionFun/TransitionFun/METransitionsViewController.m)中一样，我在viewDidLoad of my topView NavigationController中这样做：

id<ECSlidingViewControllerDelegate> transition = [[MEZoomAnimationController alloc] init];
self.slidingViewController.delegate = transition;

self.slidingViewController.topViewAnchoredGesture = ECSlidingViewControllerAnchoredGestureTapping | ECSlidingViewControllerAnchoredGesturePanning;
self.slidingViewController.customAnchoredGestures = @[];
[self.navigationController.view removeGestureRecognizer:self.dynamicTransitionPanGesture];
[self.navigationController.view addGestureRecognizer:self.slidingViewController.panGesture];

我在NavigationController头文件中采用了NavigationController协议。

但是它在ECSlidingViewController.m中崩溃，在这个方法的第一个条件下，我得到一个EXC_BAD_ACCESS(1)错误：

- (CGRect)frameFromDelegateForViewController:(UIViewController *)viewController
                         topViewPosition:(ECSlidingViewControllerTopViewPosition)topViewPosition {
     CGRect frame = CGRectInfinite;

     if ([(NSObject *)self.delegate respondsToSelector:@selector(slidingViewController:layoutControllerForTopViewPosition:)]) {
    id<ECSlidingViewControllerLayout> layoutController = [self.delegate slidingViewController:self
                                                           layoutControllerForTopViewPosition:topViewPosition];

    if (layoutController) {
        frame = [layoutController slidingViewController:self
                                 frameForViewController:viewController
                                        topViewPosition:topViewPosition];
    }
}

return frame;

}

有同样问题的人吗？thx

这就是我在视图控制器的viewDidLoad:方法中所做的工作，它工作得很好：

id<ECSlidingViewControllerDelegate> transition = self.zoomAnimationController;
self.slidingViewController.delegate = transition;
self.slidingViewController.topViewAnchoredGesture = ECSlidingViewControllerAnchoredGestureTapping | ECSlidingViewControllerAnchoredGesturePanning;
self.slidingViewController.customAnchoredGestures = @[];
[self.navigationController.view addGestureRecognizer:self.slidingViewController.panGesture];

如果像我一样，您没有尝试实现动态转换，那么您应该去掉下面这一行：

[self.navigationController.viewremoveGestureRecognizer:self.dynamicTransitionPanGesture];

由于您还没有实际设置EXC_BAD_ACCESS手势识别器，所以IMHO可能导致您的dynamicTransitionPanGesture (1)错误。
