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;
}
