iOS8推送注册方式改变

如题，笔者近期开发项目需要远程推送，注册远程通知后不调用didRegisterForRemoteNotificationsWithDeviceToken方法，多方查阅资料得知iOS8推送注册方式改变，注册代码如下：

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    //首次打开应用，跳转登录界面
    
    
    //登录成功，跳转主界面
    [self LoadMainView];
    
    //注册远程通知
    if ([[UIDevice currentDevice].systemVersion floatValue] < 8.0)
    {
        UIRemoteNotificationType type = UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound;
        
        [application registerForRemoteNotificationTypes:type];
        
    }
    else
    {
        UIUserNotificationType type = UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;
        
        UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:type categories:nil];
        
        [application registerUserNotificationSettings:setting];
        
    }
    
    
    return YES;
}

#pragma mark 注册远程通知代理方法，返回deviceToken

#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
    //register to receive notifications
    [application registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
{
    //handle the actions
    if ([identifier isEqualToString:@"declineAction"]){
    }
    else if ([identifier isEqualToString:@"answerAction"]){
    }
}
#endif

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    NSString* newToken = [[[NSString stringWithFormat:@"%@",deviceToken]
                           stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]] stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"nsdata:%@\n 字符串token: %@",deviceToken, newToken);// 获取device token
    //将token发送给服务器
}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
    NSLog(@"RegistFail %@",error);
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
    
}

• iOS8之后注册远程通知需要实现代理方法：

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
    //register to receive notifications
    [application registerForRemoteNotifications];
}

实现上述代理方法后，即可在APNS注册成功，获得返回的deviceToken
