如何使用 enabledRemoteNotificationTypes 更新代码，因为它“在 iOS 8 中不受支持"? [英] How to update code using enabledRemoteNotificationTypes because it is "not supported in iOS 8"?

问题描述

这是我用于 RemoteNotificationType 的代码:

this is the code i used for the RemoteNotificationType:

NSUInteger rntypes = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

我得到的错误是这样的:

The error i got was this:

2014-09-29 15:46:47.416 Dummy[258:21766] enabledRemoteNotificationTypes 在 iOS 8.0 及更高版本中不受支持.

2014-09-29 15:46:47.416 Dummy[258:21766] enabledRemoteNotificationTypes is not supported in iOS 8.0 and later.

如果有人能给我解决方案，那将是一个很大的帮助.

Would be a great help if someone could give me the solution.

推荐答案

您也可以使用此代码:

if ([[UIApplication sharedApplication] respondsToSelector:@selector(currentUserNotificationSettings)]) {

    UIUserNotificationType types = [[[UIApplication sharedApplication] currentUserNotificationSettings] types];

    if (types == UIUserNotificationTypeNone) {
        // Do something
    }

} else {

    UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

    if (types == UIRemoteNotificationTypeNone) {
        // Do something
    }
}

或者如果您只想检查用户是否注册了远程通知，则使用此方法:

Or this one if you only want to check the user is registered for remote notifications:

if ([[UIApplication sharedApplication] respondsToSelector:@selector(isRegisteredForRemoteNotifications)]) {

    BOOL isRegisteredForRemoteNotifications = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];

    if (isRegisteredForRemoteNotifications) { 
        // Do something
    }

} else {

    UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

    if (types == UIRemoteNotificationTypeNone) {
        // Do something
    }
}
