iOS10通知(一)--申请授权、注册和获取授权信息

此系列工程开发环境为xcode 8.2

1、创建工程，开启通知权限。开启后如果确认证书和自己的Boundle ID设置正确的情况下，第一个出现红色的叉叉，可以尝试clear之后退出xcode

2、创建通知的代理管理类（NotificationHandle），这样可以将代码分类管理

#import <Foundation/Foundation.h>#import <UIKit/UIKit.h>#import <UserNotifications/UserNotifications.h>@interface NotificationHandle : NSObject<UNUserNotificationCenterDelegate>+(NotificationHandle *) shareInstance;-(void)authorizationPushNotificaton:(UIApplication *)application;@end

@implementation NotificationHandle+(NotificationHandle *) shareInstance{    static NotificationHandle *instance = nil;    static dispatch_once_t onceToken;    dispatch_once(&onceToken, ^{        instance = [[[self class] alloc] init];    });    return instance;}-(void)authorizationPushNotificaton:(UIApplication *)application{    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];    center.delegate = self; //必须写代理    [center requestAuthorizationWithOptions:UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionCarPlay completionHandler:^(BOOL granted, NSError * _Nullable error) {        //注册之后的回调        if (!error && granted) {            NSLog(@"注册成功...");        }        else{            NSLog(@"注册失败...");        }    }];        //获取注册之后的权限设置    //注意UNNotificationSettings是只读对象哦，不能直接修改！    [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {        NSLog(@"通知配置信息:\n%@",settings);    }];        //注册通知获取token    [application registerForRemoteNotifications];}#pragma mark UNUserNotificationCenterDelegate//收到通知-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{    //收到推送的请求    UNNotificationRequest *request = notification.request;        //收到的内容    UNNotificationContent *content = request.content;        //收到用户的基本信息    NSDictionary *userInfo = content.userInfo;        //收到消息的角标    NSNumber *badge = content.badge;        //收到消息的body    NSString *body = content.body;        //收到消息的声音    UNNotificationSound *sound = content.sound;        //推送消息的副标题    NSString *subtitle = content.subtitle;        //推送消息的标题    NSString *title = content.title;        if ([notification.request.trigger isKindOfClass:[UNNotificationTrigger class]]) {        NSLog(@"前台收到通知:%@\n",userInfo);    }    else{        NSLog(@"前台收到通知:{\nbody:%@，\ntitle:%@,\nsubtitle:%@,\nbadge：%@，\nsound：%@，\nuserInfo：%@}",body,title,subtitle,badge,sound,userInfo);    }    //不管前台后台状态下。推送消息的横幅都可以展示出来！有Badge、Sound、Alert三种类型可以设置    completionHandler(UNNotificationPresentationOptionBadge | UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert);}//app通知的点击事件-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler{    //收到推送的请求    UNNotificationRequest *request = response.notification.request;        //收到的内容    UNNotificationContent *content = request.content;        //收到用户的基本信息    NSDictionary *userInfo = content.userInfo;        //收到消息的角标    NSNumber *badge = content.badge;        //收到消息的body    NSString *body = content.body;        //收到消息的声音    UNNotificationSound *sound = content.sound;        //推送消息的副标题    NSString *subtitle = content.subtitle;        //推送消息的标题    NSString *title = content.title;        if ([response.notification.request.trigger isKindOfClass:[UNNotificationTrigger class]]) {        NSLog(@"点击了通知:%@\n",userInfo);    }    else{        NSLog(@"通知:{\nbody:%@，\ntitle:%@,\nsubtitle:%@,\nbadge：%@，\nsound：%@，\nuserInfo：%@}",body,title,subtitle,badge,sound,userInfo);    }    completionHandler();} @end

3、在AppDelegate中申请授权

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    // Override point for customization after application launch.        _window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];    RootViewController *rootVC = [[RootViewController alloc]init];    UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:rootVC];        _window.rootViewController = nav;    [_window makeKeyWindow];        [UNUserNotificationCenter currentNotificationCenter].delegate = [NotificationHandle shareInstance];        [[NotificationHandle shareInstance] authorizationPushNotificaton:application];        return YES;}

4、实现注册token成功和失败的处理

-(void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{        NSString *deviceString = [[deviceToken description] stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];    deviceString = [deviceString stringByReplacingOccurrencesOfString:@" " withString:@""];        NSLog(@"远端获取的deviceToken\n%@",deviceString);        //存储得到的token，后面备用    [[NSUserDefaults standardUserDefaults] setValue:deviceString forKey:@"deviceToken"];    [[NSUserDefaults standardUserDefaults] synchronize];}-(void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{    NSLog(@"获取token失败:%@\n",error.localizedDescription);}

5、启动app，弹出通知授权，允许之后就可以进到授权信息界面实现获取授权信息了，界面UI自行布局，下面给出获取授权信息的关键代码

-(void)setData{    self.deviceTokenLabel.text = [[NSUserDefaults standardUserDefaults] valueForKey:@"deviceToken"];        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];    __weak typeof(&*self) weakSelf = self;    [center getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {        weakSelf.centerLabel.text = [weakSelf getSettingDescribe:settings.notificationCenterSetting];        weakSelf.soundLabel.text = [weakSelf getSettingDescribe:settings.soundSetting];        weakSelf.badgeLabel.text = [weakSelf getSettingDescribe:settings.badgeSetting];        weakSelf.lockScreenLabel.text = [weakSelf getSettingDescribe:settings.lockScreenSetting];        weakSelf.alertLabel.text = [weakSelf getSettingDescribe:settings.alertSetting];        weakSelf.carPlayLabel.text = [weakSelf getSettingDescribe:settings.carPlaySetting];        weakSelf.alertStyleLabel.text = [weakSelf getAlertStyleDescribe:settings.alertStyle];    }];}-(NSString *)getAlertStyleDescribe:(NSInteger)alertStyle{    NSString *backStr = @"";    switch (alertStyle) {        case 0:            backStr = @"UNAlertStyleNone";            break;        case 1:            backStr = @"UNAlertStyleBanner";            break;        case 2:            backStr = @"UNAlertStyleAlert";            break;        default:            backStr = @"UNKNOW";            break;    }    return backStr;}-(NSString *)getSettingDescribe:(NSInteger)setting{    NSString *backStr = @"";    switch (setting) {        case 0:            backStr = @"NotSupported";            break;        case 1:            backStr = @"Disabled";            break;        case 2:            backStr = @"Enabled";            break;        default:            backStr = @"UNKNOW";            break;    }    return backStr;}
