【问题描述】：

我在我的项目中使用 Parse SDK 进行推送通知。我已经在 parse.com 上添加了 didFinishLaunchingWithOptions: 中的代码

UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                UIUserNotificationTypeBadge |
                                                UIUserNotificationTypeSound);
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                         categories:nil];


[application registerUserNotificationSettings:settings];
[application registerForRemoteNotifications];

如果设备或模拟器版本是 ios 8，它工作正常，但在 iOS 6.1 中不工作，并出现消息

[UIApplication registerUserNotificationSettings:]: unrecognized selector sent to instance 0x208406c0

谁能告诉我怎么解决？

【参考方案1】：

在 didFinishLaunchingWithOptions 方法中使用此代码，它适用于 ios 6 和 7

[application registerForRemoteNotificationTypes:
         (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];

如果您想在所有情况下都在 ios 6、7、8 中工作，则在 didFinishLaunchingWithOptions 中使用此代码

 if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
    
        // iOS 8 Notifications
        [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

        [application registerForRemoteNotifications];
    
    else
    
        // iOS < 8 Notifications
        [application registerForRemoteNotificationTypes:
         (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
    

【讨论】：

效果很好，但有什么缺点吗？

@Yko，我在很多项目中都使用过它，但没有遇到任何问题。

【参考方案2】：

对于 iOS8：

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) 
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
 else 
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
