Xamarin.iOS应用在iOS13上启动时崩溃

时间：2019-09-17 21:26:07

标签： ios xamarin xamarin.ios

几周前，我开始收到用户的反馈，这些反馈是我的应用在更新至iOS 13 beta后在启动时崩溃。较旧的iOS版本没有任何类似的问题。以前的版本是使用2019年4月提供的最新SDK构建的。现在，我已升级到VS for Mac 8.2.6（内部版本73），Xcode 11预览频道，Xcode 11 GM 2并重建了我的应用程序。该应用程序在我测试过的所有iOS 13模拟器（以及发布版本）中均能正常运行，但是TestFlight用户仍然说该应用程序在启动时崩溃。我无法使用自己的iPhone设备对此进行测试，因为将其更新到iOS 13 Beta失败。我已经调查了从一个用户那里收到的崩溃日志，但是找不到崩溃的原因。任何想法是什么问题？

当前发生崩溃的设备为iPhone 7，iPhoneX。根据分析数据，并非所有iOS 13设备都存在此问题（确切的设备型号未知）。

6 个答案:

答案 0 :(得分：7)

您正在使用蓝牙吗？如果是这样，您是否已将密钥NSBluetoothPeripheralUsageDescription和NSBluetoothAlwaysUsageDescription添加到Info.plist？更新到iOS 13后，我的应用程序在启动时崩溃，直到我添加了它们。

答案 1 :(得分：3)

崩溃是由以下代码引起的：

var allNotifications = UIApplication.SharedApplication.ScheduledLocalNotifications;
foreach (var notification in allNotifications)
{
...
}

在iOS 12及更低版本中，UIApplication.SharedApplication.ScheduledLocalNotifications如果没有任何计划的本地通知，则返回空数组。在iOS 13中，它返回null。因此，添加null检查可以解决此问题。

它也可能返回null，因为自iOS 10起API UIApplication.SharedApplication.ScheduledLocalNotifications已被弃用。我现在升级到新的API UNUserNotificationCenter.GetPendingNotificationRequests，并注意到新的API也需要进行null检查。 / p>

答案 2 :(得分：3)

要在设备的发行版上获得类似崩溃的控制台输出：
将设备连接到Mac
打开XCode
转到窗口->设备和模拟器
单击设备的打开控制台
在搜索窗口中输入您的应用名称以过滤输出

我以这种方式发现了异常。问题中发布的崩溃日志没有帮助，因为这只是苹果主线程崩溃了。

对于我们来说，崩溃是由于使用了不推荐使用的类UISearchDisplayController引起的，应将其替换为UISearchController。
它可以继续在iOS12中工作，但不能在iOS13中工作。我认为它在iOS8中已过时，足够公平了。

您可能必须将应用程序上载到App Store Connect并通过TestFlight运行，以查看日志（不确定）。

此外，这可能无关紧要，但是请转到您的iPhone设置->隐私->分析->与应用开发者共享并共享iPhone分析

答案 3 :(得分：0)

下图显示“搜索显示控制器”。我什至没有使用它（因为它已经很老了），但是它以某种方式导致了iOS 13的问题（仅适用于生产版本）。我希望这对其他人有帮助。

简单删除（或重新编码）和生产版本现在可以使用。

所有功劳归于@sschmidTU，感谢您的上述回答。

答案 4 :(得分：0)

我只是遇到这样的情况，我的应用只能在发布模式下无法在iOS物理设备上启动。最后，将其跟踪到一个静态类，该类在构造函数中使用Device.StartTimer启动计时器。在global :: Xamarin.Forms.Forms.Init（）;之前已使用过它。被调用或至少完成。我没有得到有用的日志记录信息，但是在标记了大部分应用程序并仅留下初始屏幕之后，在发行版上运行调试为我提供了一个可读的例外，即无法在Forms.Init之前使用它。我将其从构造函数移至该类的初始化函数，并且一切正常。该代码以前没有引起问题，仅导致物理iOS设备上的发行版崩溃。没什么让它进入分析区域的崩溃日志中。如果您遇到这些极其令人沮丧的nostart-no-info事件之一，这只是另一种模式。

答案 5 :(得分：0)

在我的情况下，这是* iOS.csproj文件中的双重MtouchLink配置：

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|iPhone' "> ... 
   <MtouchLink>SdkOnly</MtouchLink> 
   <MtouchLink>Full</MtouchLink>

VS保存了两个链接器行为配置，并且在显示LaunchScreen图像后（仅在发布模式下），该应用程序崩溃了。

要纠正此问题，只需使用文本编辑器编辑* iOS.csproj文件，然后删除其中一个MtouchLink配置：

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|iPhone' "> ... 
   <MtouchLink>SdkOnly</MtouchLink>
