Question

我从另一个Controller通过Myservice获取一些数据。我可以从视图中看到import UIKit class RadioWaveAnimationView: UIView { var animatableLayer : CAShapeLayer? override func awakeFromNib() { super.awakeFromNib() self.layer.cornerRadius = self.bounds.height/2 self.animatableLayer = CAShapeLayer() self.animatableLayer?.fillColor = self.backgroundColor?.cgColor self.animatableLayer?.path = UIBezierPath(roundedRect: self.bounds, cornerRadius: self.layer.cornerRadius).cgPath self.animatableLayer?.frame = self.bounds self.animatableLayer?.cornerRadius = self.bounds.height/2 self.animatableLayer?.masksToBounds = true self.layer.addSublayer(self.animatableLayer!) self.startAnimation() } func startAnimation() { let layerAnimation = CABasicAnimation(keyPath: "transform.scale") layerAnimation.fromValue = 1 layerAnimation.toValue = 3 layerAnimation.isAdditive = false let layerAnimation2 = CABasicAnimation(keyPath: "opacity") layerAnimation2.fromValue = 1 layerAnimation2.toValue = 0 layerAnimation2.isAdditive = false let groupAnimation = CAAnimationGroup() groupAnimation.animations = [layerAnimation,layerAnimation2] groupAnimation.duration = CFTimeInterval(2) groupAnimation.fillMode = kCAFillModeForwards groupAnimation.isRemovedOnCompletion = true groupAnimation.repeatCount = .infinity self.animatableLayer?.add(groupAnimation, forKey: "growingAnimation") } /* // Only override draw() if you perform custom drawing. // An empty implementation adversely affects performance during animation. override func draw(_ rect: CGRect) { // Drawing code } */ }，但{{users.data}}和users.length = 0为空，这意味着我无法访问getData函数中的MyService内容。如果我将MyService替换为json的数据就像 $data它运作正常谢谢..

$scope.users=[{..},{..}]

当您在第一个控制器中获取数据时，您调用MyService.setData(data);该服务将存储在其本地var data中并保留在那里。然后在第二个控制器中，您可以通过调用MyService.getData()

来检索该数据

app.service('MyService', function() {

    var ret =  {
        data: [],
        setData: function(inData) {
            ret.data = inData;
        },
        getData: function() {
            return ret.data;
        }
    };
    return ret;
});

第一个控制器1

app.controller('EventCtrl', ['$scope', 'EventService', 'MyService',

    function ($scope, EventService , MyService) {

        var baseUrl = '';

        $scope.getEvents=function()
        {
            var apiRoute = 'http://localhost:9811/notification/notification/';
            var _Event = EventService.getAll(apiRoute);
            _Event.then(function (response) {
                    $scope.events= response.data;
                    MyService.data = $scope.events;
                    MyService.setData($scope.events);
                    $scope.VarCtrl1= MyService;

                },
                function (error) {
                    console.log("Error: " + error);
                });

        }
        $scope.getEvents()
    }]);

我更新了服务，但它不起作用..所以我修改了第一个这样的控制器你觉得怎么样？

app.controller('EventCtrl', ['$scope', 'EventService', 'MyService',

  function ($scope, EventService , MyService) {

    var baseUrl = '';

    $scope.getEvents=function()
    {
        var apiRoute = 
   'http://localhost:9811/notification/notification/';
        var _Event = EventService.getAll(apiRoute);
        _Event.then(function (response) {
            var data = response.data
                MyService.setData(data);
                $scope.VarCtrl1= MyService;

            },
            function (error) {
                console.log("Error: " + error);
            });

    }
    $scope.getEvents()
}]);

感谢服务的更新现在它更好...我可以在$ users和$ data in tableController中有数据但是orderBy需要一个数组但我得到这个:(当我做consoleLoge（$ scope.users） Object {data：Array（0），setData：function，getData：function} data： Array（9）0：Object1：Object2：Object3：Object4：Object5：Object6： Object7：Object8：Objectlength：9__proto __：Array（0）getData： function（）setData：function（inData） proto ：Object tableController.js：24

使用其他服务在同一控制器中的函数之间传递数据以获取数据
