ios7 中 不能显示

[jiangmingz]

UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:viewController];
navigation.modalPresentationStyle = UIModalPresentationCustom;
navigation.transitioningDelegate = self.transitionAnimator;
[self presentViewController:navigation animated:YES completion:nil];

Warning: Attempt to present <UINavigationController: 0x1558c390> on <UINavigationController: 0x1553a550> which is already presenting <UINavigationController: 0x15580ae0>
不能显示controller

你去搜索一下吧，bug与这个无关

恩，我正在查询，我用的是你的demo在真机上调试也是一样的。 CGRect ToViewFinalRect = [transitionContext finalFrameForViewController:toViewController];
这个返回的CGRectZero

嗯，我也看看这个，好久一直没时间看这个
