Ios Estimote beacons近距离演示将ViewController推到“上”；立即；案例

我在做estimote beacon

我尝试在切换为“立即”时显示ViewController。 但是，当我加载视图时，我有一个警告：

2014-03-13 02:44:26.017 ProximityDemo[856:60b]警告：试图在其视图不在窗口层次结构中的对象上显示

为什么?？我认为当我使用新视图时，presentView方法仍然有效

此外，当我在新视图上时，我希望在“接近”时弹出到旧视图

我想我必须在新的ViewController中实现所有代码？（presentProductViewController） 是否有办法将所有接近/距离控制仅放在一个控制器中

这是我的密码：
