Question

我在Cordova中有一个iOS应用程序，其中使用OneSignal实现了推送通知。

我已按照here

中提供的文档中的所有步骤进行操作

问题是，当我使用XCode安装应用程序时，应用程序会询问，

AppName想向您发送通知

但是此后一切都变成黑屏。

我认为是由于以下的AppDelegate.m文件

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // Replace '11111111-2222-3333-4444-0123456789ab' with your OneSignal App ID.
    [OneSignal initWithLaunchOptions:launchOptions
                               appId:@"11111111-2222-3333-4444-0123456789ab"
            handleNotificationAction:nil
                            settings:@{kOSSettingsKeyAutoPrompt: @false}];
    OneSignal.inFocusDisplayType = OSNotificationDisplayTypeNotification;

    // Recommend moving the below line to prompt for push after informing the user about
    //   how your app will use them.
    [OneSignal promptForPushNotificationsWithUserResponse:^(BOOL accepted) {
        NSLog(@"User accepted notifications: %d", accepted);
    }];

    return YES;
}

@end

我也替换了ID。在XCode日志中，它显示的警告很少，

Answer 1

我认为有两个独立的问题。黑屏问题的原因可能是该应用程序不知道要显示哪个View Controller。如果您使用的是故事板，则可以将所需的View Controller设置为“ Initial View Controller”。

或者您可以添加

self.window.rootViewController = self.viewController; [self.window makeKeyAndVisible];

到结尾：

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions

正好位于return YES;

上方

Answer 2

请添加以下方法来处理您的appdelegate中的通知。

   -(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    NSLog(@"Application registered for notification");
}

-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
    NSLog(@"Failed to register notification for application");
}

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{

}

-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)(void))completionHandler
{

}

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{

}

添加AppDelegate
