设置hidesBarsOnSwipe = YES有时会导致应用程序崩溃（uvSendEvents）

Question

如果用户反复向上/向下滚动，设置hidesBarsOnSwipe = YES会导致我的应用程序崩溃。我有来自Crashlytics的报告但无法一致地重现它。

我在openradar中发现了相同的错误报告，但无法找到解决方案。 https://github.com/lionheart/openradar-mirror/issues/236 http://www.openradar.appspot.com/20000000

请帮忙

Answer 1

您是否有自定义导航栏？我有同样的问题，并按照Apple的NavBar示例中使用的自定义模式修复了我的问题（我怀疑它正在实现layoutSubviews并清理视图层次结构）。

Answer 2

我有同样的问题。我做错的事情是我保留了navigationController的属性 -

self.navigationController?.hidesBarsOnSwipe = true

<强>加

我在滚动时手动管理导航控制器隐藏/取消隐藏。

因此两个过渡同时重叠。
