查看不可用dismissViewControllerAnimated后：完成： [英] View unusable after dismissViewControllerAnimated:completion:

问题描述

我移植较老的code所用钞使用手动视图创建（的loadView ）和自动布局的。根视图控制器是一个容器VC （含2名儿童），使用自动布局和模态presents有一个NIB指定的布局，还没有使用自动布局的视图控制器。所有 presentViewController后罚款：动画：完成：，但是当模态视图与收dismissViewControllerAnimated：完成：通过委托调用，presenting视图留在内容古怪移动并没有反应碰一个陌生的，不可用状态。

I'm migrating older code that used NIBs to use manual view creation (loadView) and Auto Layout. The root view controller is a container VC (with 2 children) that uses auto layout and modally presents a view controller that has its layout specified in a NIB and does not yet use auto layout. All is fine after presentViewController:animated:completion:, but when the modal view is closed with dismissViewControllerAnimated:completion: via delegate call, the presenting view is left in a strange, unusable state where the content is weirdly shifted and does not react to touch.

我曾尝试创建最小的测试案例重现该问题，但我没能重现该问题。

I have tried to create minimal test case to reproduce the problem, but I've failed to reproduce the issue.

什么引起的？

推荐答案

我设置 translatesAutoresizingMaskIntoConstraints = NO; 我的根的UIView 。
它显示外层的UIView - 在您的视图层次必须使用默认的根目录下的上海华 translatesAutoresizingMaskIntoConstraints = YES 。
一旦我删除这一点，一切都如预期。

I was setting translatesAutoresizingMaskIntoConstraints = NO; on my root UIView. It appears the "outermost" UIView — the superview at the root of your view hierarchy must use the default translatesAutoresizingMaskIntoConstraints = YES. Once I've removed this, everything worked as expected.
