0、被坑等级：五星

⭐️⭐️⭐️⭐️⭐️

1、测试过程&结果

本来测试中，N台手机，接收push正常，毕竟Ios11、Ios12上收发push都是正常的，机型你也兼容了好几个，结果，没想到兼容性出现问题

结果：一台iphone se ，ios 10.3.3的系统，launcher上有数字提示，震动也有，通知栏就是没有Notificaiton

2、兼容类型：操作系统

3、解决方案，两种方式

方案1:不要让body的值是空的“”，下面例子中，还加入了subtitle

{
  "aps" : {
    "alert" : {
      "title" : "iOS远程消息，我是主标题！-title",
      "subtitle" : "iOS远程消息，我是主标题！-Subtitle",
      "body" : "Dely,why am i so handsome -body"
    },
    "badge" : "2"
  }
}

方案2:alert的值不要json对象，直接用字符串即可

{
  "aps" : {
    "alert" : “方案2”,
    "badge" : "2"
  }
}

4、总结

兼容性测试的重要性，可见不容忽视，不然就是一个大坑，该现象极为严重。push验证记住一定要在所有大系统上都ok
