本地通知应用程序崩溃模拟器

Question

我将本地通知插件 (https://github.com/katzer/cordova-plugin-local-notifications/) 与 ng-cordova 一起用于离子项目：

这是我的控制器：

.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');
            });
    };
})

我在默认视图上有一个按钮，当应用程序以 ng-click 启动时加载，如下所示：

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

但是当我在模拟器中运行应用程序并点击按钮时，应用程序崩溃并显示以下错误消息：

: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-     [__NSCFString stringValue]: unrecognized selector sent to instance 0x7a840850'

有没有人按照 ng-cordova 文档让它工作，或者我应该尝试另一种方法。

谢谢！

如果你仍然有这个问题，我今天也遇到了这个问题。

进入插件代码，Xcode 中的 APPLocalNotifications.m 并将这一行更改为底部：

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

并将其替换为：

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

今天这对我有用。
