iOS8 获取推送的设备token(deviceToken)

最近升级设备，测试时发现无法获得设备token,查资料发现，原来ios的apns注册与以往不同了。

首先在

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中将之前注册推送代码更改如下：

    //APNS注册

//APNS 注册

    if (iOS8) {

        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge

                                                                                             |UIRemoteNotificationTypeSound

                                                                                             |UIRemoteNotificationTypeAlert) categories:nil];

        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

    }else

    {

        UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;

        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];

    }

注：

#define iOS8 [[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0 ? 1 : 0

然后添加两个ios8的新方法

#pragma mark APPLE APNS 

#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

下面就可以正常在“

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken 

”中获取设备token 了

如果获取失败，可以在“

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error

”中打印错误信息
