至少我应该摆脱这个警告

At least I should get rid of this warning

推荐答案

在推送视图检查天气之前，视图已经存在，并且如果已经存在，则将其消除，因此您不会收到这些警告并且可以轻松导航。

Before pushing a view check weather the view already exists, and destroy it if its already there, so you wont get those warnings and can navigate easily.

if(Ext.getCmp('myView')){
                Ext.getCmp('myView').destroy();
}

//Push myView

where  myView should be the id of that view declared in config of that view


    config: {

        id:'myView',

    }
