NSNotification是抽象的,不可见的
推送通知是可见的(肉眼可见的)
本地推送通知(Local Notification)
远程推送通知(Remote Notification)
可以让不再前台运行的app,告知用户app内部发生了什么事情
在屏幕顶部显示一块横幅(显示具体内容)
在屏幕中间弹出一个UIAlertView(显示具体内容)
在锁屏界面显示一块横幅(锁屏状态下,显示具体内容)
更新app图标的数字(说明新内容的数量)
播放音效(提醒作用)
注册推送通知(本地)
- 本地推送通知:不需要联网就能发出推送通知(不需要服务器的支持)
- 使用场景:常用来定时提醒用户完成一些任务(清理垃圾 记账 看电影 玩游戏)

远程推送
从服务器推送给客户端的通知(需要联网)
远程推送服务,又称APNs(Apple Push Notification Services)
不管用户打开还是关闭app,只要联网,都能收到服务器推送的远程通知
所有的苹果设备,在联网的状态下,都会与苹果的服务器建立长连接
UDID手机唯一标识+bundleID应用程序唯一标识 -> deviceToken
远程推送实现

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//1.请求用户授权

//2.获取deviceToken 向苹果发送服务

return YES;
}
//当苹果加密成功后,返回deviceToken

NSLog(@"%@",deviceToken);
}
//当苹果加密失败,返回原因
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
NSLog(@"%@",error);
}
//写在didFinishLaunchingWithOptions中,程序被杀死时远程推送
if(launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]){

label.text = [NSString stringWithFormat:@"%@",launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]];
label.numberOfLines = 0;
[self.window.rootViewController.view addSubview:label];
//接收到了远程推送通知 程序在前台和后台运行时能够接受
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
NSLog(@"%@",userInfo);
