iOS上的bms-push cordova插件给出：致命错误：意外地发现零，同时展开可选值

Question

我已经使用新的bms-push cordova插件实施了Ionic测试应用程序。

它在Android上正常工作。

然而，在推出iOS版应用程序时，它会立即失败：

fatal error: unexpectedly found nil while unwrapping an Optional value

在CDVBMSPush类的didReceiveRemoteNotificationOnLaunch功能时发生错误。

如果我在AppDelegate.m

[[CDVBMSPush sharedInstance] didReceiveRemoteNotificationOnLaunchWithLaunchOptions:launchOptions];

注释掉以下行然后应用程序正常启动。

有什么建议可以解决这个问题吗？ THX

Answer 1

单从支持团队得到了一个answer：

[[CDVBMSPush sharedInstance] didReceiveRemoteNotificationOnLaunchWithLaunchOptions:launchOptions];

This is only used when app is opened by clicking push notifications.

At the first time launchOptions will be nil. That why its failing.

Solutions:

1. you can add a check there whether the launchOptions is of type remoteNotificationKey, If yes then add the [[CDVBMSPush sharedInstance] didReceiveRemoteNotificationOnLaunchWithLaunchOptions:launchOptions];

Example:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
    if (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]) { 
     [[CDVBMSPush sharedInstance] didReceiveRemoteNotificationOnLaunchWithLaunchOptions:launchOptions]; 
    } 
} 

2. Completely remove that line of code.
