ios本地通知

什么时候需要推送跳转

1, 程序在后台（用户如果在app内，此时是不能推送的）
2， 程序被杀死，此时通过didReceiveLocalNotification监听不到，我们需要在程序的didFinishLaunchingWithOptions当中判断     launchOptions[UIApplicationLaunchOptionsLocalNotificationKey]

    //通知的标题
    
    notification.alertTitle=@"我的账本";

    //设置图标上小红点的数量

    //通过通知启动时代app启动图，这里我们随便写上一个，到时候程序会使用我们的默认启动图
    notification.alertLaunchImage=@"lllllasd";
    
    //设置推送声音,可以自定义声音@"a.wav"
    notification.soundName=UILocalNotificationDefaultSoundName;
    
    //设置其他的额外信息
    notification.userInfo=@{@"type":@"chatPage"};
    
    //调用通知
    //还需要在我们的appdelegate当中注册该通知才行
