我在应用程序商店中有一个应用程序,并且有一个崩溃报告显示有一个非常偶然的崩溃,详情如下：

我的应用程序不使用UIPresentationController,为什么这显示为线程0中的最后一行是崩溃的线程？
解决方法
如果不仔细查看您的代码,这很难回答.通常,您应该检查可能忽略的可能类(包括系统框架)实际上是UIPresentationController的子类.此外,第三方库可能正在引用此类(或子类).
但最有可能的是,这是UIKit的崩溃. UIPresentationController是一个提供高级视图控制器管理并处理控制器之间转换的类.最有可能的是,UIKit在某处崩溃(很可能是由于你的代码).更多信息在Apple docs.
