iOS 远程推送 根据后台推送内容的不同跳转指定页面

iOS 远程推送，根据后台推送内容的不同， 跳转指定页面
我目前的需求是总体分为两类：
1:私信、关注、点赞一类，只需跳转到对应的tabbar 中的某一项
2:每日精品文章项目推送，分两个子类
（1）如果当前已经打开 文章项目页面，则直接刷新，不推出新页面
（2）如果当前未打开此页面，则push出新的文章项目页面

iOS  推送情况分为 
应用未启动的 情况：
打开应用 ，推送信息 会通过
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions：
此方法传递，内容在launchOptions里面， 通过控制台即可看出
应用已启动的 情况：（1）应用在前台活跃 （前台活跃 只做 页面的体型，alert，不去主动帮用
户打开新的界面）
（2）应用在后台挂起  (后台挂起转为 活跃时 调用此方法)
- (void)didReceiveRemoteNotification:(NSDictionary *)userInfo 


结论，我们要做的就是 通过系统的两个方法拿到推送信息后：
1、 如果是从第一个方法里边获得的信息， 则 延迟0.5秒左右跳转新页面（我做推送的时候直接 跳转会出现异常异常），这种情况不需要判断当前的 controller
2、从第二种方法里边获取信息， 判断当前controller，是否需要push新的页面，或者回到tabbar 

下面是 我这边的代码，具体 信息 字段根据你们后台来定
使用到了 类别，方便统一管理
推送平台根据你们自己所使用的来配置 （）
