推送通知跟NSNotification有所区别:
NSNotification是抽象的，不可见的
推送通知是可见的（能用肉眼看到）
iOS中提供了2种推送通知
本地推送通知（Local Notification）
远程推送通知（Remote Notification）
推送通知有5种不同的呈现效果:
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）
如何发送本地通知:
创建本地推送通知对象
UILocalNotification *ln = [[UILocalNotification alloc] init];
设置本地推送通知属性
推送通知的触发时间（何时发出推送通知）
@property(nonatomic,copy) NSDate *fireDate;
推送通知的具体内容
@property(nonatomic,copy) NSString *alertBody;
在锁屏时显示的动作标题（完整标题：“滑动来” + alertAction）
@property(nonatomic,copy) NSString *alertAction;
音效文件名
@property(nonatomic,copy) NSString *soundName;
app图标数字
@property(nonatomic) NSInteger applicationIconBadgeNumber;
调度本地推送通知（调度完毕后，推送通知会在特地时间fireDate发出）
[[UIApplication sharedApplication] scheduleLocalNotification:ln];
获得被调度(定制)的所有本地推送通知
@property(nonatomic,copy) NSArray *scheduledLocalNotifications;
（已经发出且过期的推送通知就算调度结束，会自动从这个数组中移除）
取消调度本地推送通知
- (void)cancelLocalNotification:(UILocalNotification *)notification;
- (void)cancelAllLocalNotifications;
立即发出本地推送通知
- (void)presentLocalNotificationNow:(UILocalNotification *)notification;
本地通知的其他属性:
每隔多久重复发一次推送通知
@property(nonatomic) NSCalendarUnit repeatInterval;
点击推送通知打开app时显示的启动图片
@property(nonatomic,copy) NSString *alertLaunchImage;
附加的额外信息
@property(nonatomic,copy) NSDictionary *userInfo;
时区
@property(nonatomic,copy) NSTimeZone *timeZone;
（一般设置为[NSTimeZone defaultTimeZone] ，跟随手机的时区）
当用户点击本地推送通知，会自动打开app，这里有2种情况
app并没有关闭，一直隐藏在后台
让app进入前台，并会调用AppDelegate的下面方法（并非重新启动app）
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification;
app已经被关闭（进程已死）
启动app，启动完毕会调用AppDelegate的下面方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions;
launchOptions参数通过UIApplicationLaunchOptionsLocalNotificationKey取出本地推送通知对象
在iOS 8.0中，如果要使用本地通知，需要得到用户的许可
在didFinishLaunchingWithOptions方法中添加如下代码：
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert categories:nil];
[application registerUserNotificationSettings:settings];
远程通知是如何操作的:
1.远程通知的操作流程具体是一下几步:
抽象理解: 当服务器要给用户发送通知时, 并且用户没有启动程序, 并处于联网状态, 此时app服务器就把通知内容发送给APNs服务器,再让苹果服务器发送给用户.
详解理解: 当用户登录应用时, 此时通过苹果提供的API 将用户的UDID 和app的boundle ID 通过一种加密算法就行加密,得到一个DeviceToken发送给应用服务器储存在服务器中,当服务器要给用户推送通知时, app服务器是将通知内容以及DeviceToken发送给APNs服务器,苹果通过DeviceToken 将通知推送给用户.(注意,推送远程通知的前提,用户处于联网状态, 这样苹果设备才能与苹果服务器建立长连接, 如果用户使用APP处于前台,此时就不需要通过APNs来进行推送, app服务器就可以直接将通知发送给用户,前提是用户app处于前台)
