Question

因此，我正在开发一个针对移动设备的Xamarin项目，并且我正在使用EKEventStore API来创建事件，并且它在iOS 8和9上运行良好。但是在iOS 10上请求EKEVentStore访问时出现了问题。

以下代码在iOS 8和9上运行正常，但在iOS 10上崩溃并没有给出此错误的特定消息。

Apple似乎已经改变了在iOS 10中收集此权限的内容。

有人有同样的问题或知道一些有助于解决它的问题吗？

谢谢！

EKEntityType type = EKEntityType.Event;
Store = new EKEventStore();
EKAuthorizationStatus status = EKEventStore.GetAuthorizationStatus(type);

if (status != EKAuthorizationStatus.Authorized)
{
    if (status == EKAuthorizationStatus.NotDetermined)
    {    
        Store.RequestAccess(type, (bool granted, NSError error) =>
        {
            //Crashes before entering here
        });

        return;
    }
    else
    {
        //Denied
        return;
    }
}

输出：

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries

Answer 1

对于事件，您需要在info.plist中添加正确的密钥，在这种情况下将是NSCalendarsUsageDescription，其中值是您为什么要请求此类权限的简短描述。
希望这能解决你的问题，我有完全相同的问题（也是Xamarin），这解决了它。
