iOS---iOS10适配iOS当前所有系统的远程推送
一、iOS推送通知简介
众所周知苹果的推送通知从iOS3开始出现, 每一年都会更新一些新的用法. 譬如iOS7出现的Silent remote notifications(远程静默推送), iOS8出现的Category(分类, 也可称之为快捷回复), iOS9出现的Text Input action(文本框快捷回复).
而在iOS10, 苹果可谓是大刀阔斧般的, 对远程通知和本地通知进行了大范围的更新. iOS10推出了全新的UserNotifications框架(iOS10之前从属于UIKit框架).
新的推送通知框架, 整合了本地推送和远程推送的点击处理方法, 使得以前专门处理推送点击的方法只能处理静默推送了.
二、远程推送通知介绍
1、什么是远程推送
在联网的情况下，由远程服务器推送给客户端的通知，又称APNs(Apple Push Notification Services)不管应用是打开还是关闭的情况下，都能接收到服务器推送的远程通知在联网状态下，所有苹果设备都会与苹果服务器建立长连接
2、远程推送的实现原理:
1.打开App时: 发送UDID和BundleID给APNs加密后返回deviceToken
2.获取Token后，App调用接口,将用户身份信息和deviceToken发给服务器，服务器记录
3.当推送消息时, 服务器按照用户身份信息找到存储的deviceToken，将消息和deviToken发送给APNs
4.苹果的APNs通过deviceToken, 找到指定设备的指定程序, 并将消息推送给用户
3、实现远程推送功能的前提
1.真机
2.调试阶段的证书
iOS_development.cer 用于真机调试的证书
aps_development.cer 用于真机推送调试能的证书
xxx.mobileprovision 描述文件，记录了能够调试的手机、电脑和程序
3.发布阶段的证书
iOS_distribution.cer 用于发布app的证书
aps.cer 用于发布时,让app有推送功能的证书
xxx.mobileprovision 描述文件，记录了能够发布app的电脑
如何配置证书，请参考我的另一博文: iOS-推送，证书申请，本地推送
二、 iOS10远程推送通知的处理方法
当点击了推送后, 如果你希望进行处理. 那么在iOS10中, 还需要设置UNUserNotificationCenter的delegate, 并遵守UNUserNotificationCenterDelegate协议.
以及实现下面实现3个方法, 用于处理点击通知时的不同情况的处理
willPresentNotification:withCompletionHandler
用于前台运行
didReceiveNotificationResponse:withCompletionHandler
用于后台及程序退出
didReceiveRemoteNotification:fetchCompletionHandler
用于静默推送
1.前台运行 会调用的方法
前台运行: 指的是程序正在运行中, 用户能看见程序的界面.
iOS10会出现通知横幅, 而在以前的框架中, 前台运行时, 不会出现通知的横幅.
代码开始前的设置
iOS 10 的推送 与原来的都不一样，他把本地的推送 跟 远程的推送结合到一起了，UserNotifications.framework 库。在使用推送的时候，先开启通知的开关。
就是上面这个。当你开启后，xcode 会自动帮你在 项目里面创建一个文件，xxxx.entitlements.
这个文件是系统帮你创建的，不用管它。
在appDeletgate 文件里面需要先导入 UNUserNotificationCenterDelegate 这个代理。他的代理方法分别是
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler __IOS_AVAILABLE(10.0) __TVOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0); - (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler __IOS_AVAILABLE(10.0)
代码如下:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
/**
注册远程推送和本地通知，适配至最新系统，目前是 iOS10
*/
[self registerRemoteNotificationsForAlliOSSystemVersion];
// Override point for customization after application launch.
return YES;
}
/**
注册远程推送和本地通知，适配至最新系统，目前是 iOS10
*/
-(void)registerRemoteNotificationsForAlliOSSystemVersion{
//导入文件 #import
//去capabilities(功能)设置这边打开 pushNotifications，并且打开 backgroundModes 中的backgroundFentch，Remote Notifications
CGFloat version = [[[UIDevice currentDevice] systemVersion] floatValue];
if (version >= 10.0) {//10.0及其以上
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
//请求通知权限, 本地和远程共用
// 设定通知可选提示类型
[center requestAuthorizationWithOptions:UNAuthorizationOptionCarPlay | UNAuthorizationOptionSound | UNAuthorizationOptionBadge | UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (error) {
NSLog(@"iOS10请求 接受远程和本地通知 授权失败:<%@>",[error description]);
}
if (granted) {
NSLog(@" iOS 10 request notification success");
NSLog(@"请求成功");
}else{
NSLog(@" iOS 10 request notification fail");
NSLog(@"请求失败");
}
}];
//设置通知的代理
center.delegate = self;//1.遵守UNUserNotificationCenterDelegate协议，2.成为代理；3.实现代理回调方法
}else if (version>=8.0){//8.0--->10.0
//请求用户授权 授权收到推送时有哪些提醒方式可以选
// 声音、角标、弹窗
UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeSound | UIUserNotificationTypeBadge | UIUserNotificationTypeAlert categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:setting];
}else{//8.0以下
UIRemoteNotificationType type = UIRemoteNotificationTypeSound| UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge;
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:type];
}
//注册通知
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
#pragma mark-推送通知
//注册成功
-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
NSString *token = [deviceToken description]; //获取
token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
NSLog(@"request notificatoin token success. %@",token);
}
//注册失败
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
NSLog(@"request notification Token fail. %@",error.localizedDescription);
}
#pragma mark iOS 10 获取推送信息 UNUserNotificationCenter---Delegate

NSDictionary *userInfo = content.userInfo;
[self handleRemoteNotificationContent:userInfo];
//前台运行推送 显示红色Label
[self showLabelWithUserInfo:userInfo color:[UIColor redColor]];
//可以设置当收到通知后, 有哪些效果呈现(提醒/声音/数字角标)

completionHandler(UNNotificationPresentationOptionAlert | UNNotificationPresentationOptionSound|UNNotificationPresentationOptionBadge);
}
//APP在后台，点击推送信息，进入APP后执行的回调
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
{
UNNotificationContent *content = response.notification.request.content;
NSDictionary *userInfo = content.userInfo;

completionHandler(UIBackgroundFetchResultNewData);
}

}

label.text = userInfo.description;

[[UIApplication sharedApplication].keyWindow addSubview:label];
