看到标题你可能会觉得奇怪 推送消息提示框不是系统自己弹出来的吗? 为什么还要自己自定义呢?
因为项目需求是这样的:最近需要做 远程推送通知 和一个客服系统 包括店铺客服和官方客服两个模块 如果有新的消息推送的时候 如果用户当前不在客服界面的时候 要求无论是在app前台 还是app退到后台 顶部都要弹出系统的那种消息提示框
这样的需求 我们就只能自定义一个在app内 弹出消息提示框
实现步骤如下:
1.我们自定义一个view 为 stpushview 推送消息的提示框view

因为涉及到好几个页面需要使用同样的推送消息数据 进行判断而处理相应的业务 所有我对此模型做了归档处理

做好了上面的准备工作之后 接下来我们就需要 appdelegate里面注册远程推送通知 并且监听推送消息
这里以个推为例子:
第一步在下面的方法中 实现个推的注册方法

- ( bool )application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions { // 注册个推推送服务 [[getuiapilmpl sharedinstance] getuiregister]; } |
getuiapilmpl 是一个单例类 专门用于注册个推的推送方法 实现代码如下:

然后这些工作做好了之后 就是你需要在个推的后台 配置推送证书 这个配置的步骤 大家可以到个推官网去参考文档 配置
这里我假设 你已经配置到证书了 经过上面的步骤 我们的远程推送通知的方法 基本完成 现在我们运行 测试下 你会发现即使在前台 有新消息推送的时候 顶部也会弹出和系统一样的提示框 点击 跳转到对应的页面的方法逻辑根据你的需要 去做跳转处理
测试效果如下:
用户在后台 收到的消息提示如下:
用户在前台 收到的消息提示如下:
