ios - iOS应用程序在后台运行180秒后崩溃

Question

从控制台获取以下日志（即使在模拟器中也不会在调试模式下发生）

Can't get most elevated app state from dictionary {
BKSApplicationStateExtensionKey = 0;
SBApplicationStateDisplayIDKey = "com.App.Stage";
SBApplicationStateKey = 0;
SBApplicationStateProcessIDKey = PID;
SBApplicationStateRunningReasonsKey =     (
            {
        SBApplicationStateRunningReasonAssertionIdentifierKey = "Shared Background Assertion 2 for com.App.Stage";
        SBApplicationStateRunningReasonAssertionReasonKey = 4;
    }
);

}

这是崩溃日志
