Local notification app crashes simulator

问题:

I'm using the local notification plugin (https://github.com/katzer/cordova-plugin-local-notifications/) with ng-cordova for an ionic poject:

This is my controller:

.controller('DashCtrl', function($scope, $state, $cordovaLocalNotification) {
    $scope.addNotification = function() {
        $cordovaLocalNotification.add({
            id: 'some_notification_id'
                // parameter documentation:
                // https://github.com/katzer/cordova-plugin-local-notifications#further-informations-1
        }).then(function() {
            console.log('callback for adding background notification');
        });
    };
    $scope.checkIfIsTriggered = function() {
        $cordovaLocalNotification.isTriggered('some_notification_id').then(
            function(isTriggered) {
                alert('isTriggered');
            });
    };
})

I have a button on the default view which is loaded when the app starts with a ng-click, like so:

  <button ng-click="addNotification();" class="button button-stable">button-stable</button>

But when I run the app in the emulator and tap the button, the app crashes with the followiing error message:

Has anyone got it to work following the ng-cordova docs, or is there another approach I should be trying.

Thank's!

回答1:

If you're still having this issue, I ran into this today as well.

Go into the plugin code, APPLocalNotifications.m in Xcode and change this line, towards the bottom:

NSString* notId = [[notification.userInfo objectForKey:@"id"] stringValue];

and replace it with this:

NSString* notId = [notification.userInfo objectForKey:@"id"];

This worked for me today.
