我正在寻找一种方法来确定用户是否有,通过设置,启用或禁用他们的推送通知我的应用程序。


当前回答

quantumpotato的问题:

类型是由

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

可以使用

if (types & UIRemoteNotificationTypeAlert)

而不是

if (types == UIRemoteNotificationTypeNone) 

将允许你只检查通知是否启用(不用担心声音,徽章,通知中心等)。第一行代码(types & UIRemoteNotificationTypeAlert)如果“Alert Style”设置为“横幅”或“警报”将返回YES,如果“Alert Style”设置为“None”则返回NO,与其他设置无关。

其他回答

在iOS7和之前,你应该使用enabledRemoteNotificationTypes并检查它是否等于(或不等于取决于你想要什么)UIRemoteNotificationTypeNone。

然而,对于iOS8来说,仅仅检查isregisteredforremotenotifations并不总是足够的,因为上面有许多状态。你还应该检查application.currentUserNotificationSettings.types是否等于(或不等于取决于你想要什么)UIUserNotificationTypeNone!

isregisteredforremotenotifations可能返回true,即使currentUserNotificationSettings。types返回UIUserNotificationTypeNone。

尽管Zac的答案在iOS 7之前是完全正确的,但自从iOS 8到来后,它就发生了变化。因为enabledRemoteNotificationTypes从iOS 8开始就已经弃用了。对于iOS 8和更高版本,你需要使用isregisteredforremotenotifizations。

—>使用enabledRemoteNotificationTypes >使用isregisteredforremotenotifizations。

完全容易复制和粘贴代码构建从@ZacBowling的解决方案(https://stackoverflow.com/a/1535427/2298002)

这也将把用户带到你的应用程序设置,并允许他们立即启用

我还添加了一个解决方案,用于检查位置服务是否启用(以及带来的设置)

// check if notification service is enabled
+ (void)checkNotificationServicesEnabled
{
    if (![[UIApplication sharedApplication] isRegisteredForRemoteNotifications])
    {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Notification Services Disabled!"
                                                            message:@"Yo don't mess around bro! Enabling your Notifications allows you to receive important updates"
                                                           delegate:self
                                                  cancelButtonTitle:@"Cancel"
                                                  otherButtonTitles:@"Settings", nil];

        alertView.tag = 300;

        [alertView show];

        return;
    }
}

// check if location service is enabled (ref: https://stackoverflow.com/a/35982887/2298002)
+ (void)checkLocationServicesEnabled
{
    //Checking authorization status
    if (![CLLocationManager locationServicesEnabled] || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied)
    {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Location Services Disabled!"
                                                            message:@"You need to enable your GPS location right now!!"
                                                           delegate:self
                                                  cancelButtonTitle:@"Cancel"
                                                  otherButtonTitles:@"Settings", nil];

        //TODO if user has not given permission to device
        if (![CLLocationManager locationServicesEnabled])
        {
            alertView.tag = 100;
        }
        //TODO if user has not given permission to particular app
        else
        {
            alertView.tag = 200;
        }

        [alertView show];

        return;
    }
}

// handle bringing user to settings for each
+ (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{

    if(buttonIndex == 0)// Cancel button pressed
    {
        //TODO for cancel
    }
    else if(buttonIndex == 1)// Settings button pressed.
    {
        if (alertView.tag == 100)
        {
            //This will open ios devices location settings
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];
        }
        else if (alertView.tag == 200)
        {
            //This will open particular app location settings
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
        }
        else if (alertView.tag == 300)
        {
            //This will open particular app location settings
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
        }
    }
}

GLHF !

为了完成这个答案,它可以这样工作……

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
switch (types) {
   case UIRemoteNotificationTypeAlert:
   case UIRemoteNotificationTypeBadge:
       // For enabled code
       break;
   case UIRemoteNotificationTypeSound:
   case UIRemoteNotificationTypeNone:
   default:
       // For disabled code
       break;
}

编辑:这是不对的。因为这些是位智慧的东西,它不会与开关工作,所以我结束使用这个:

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
UIRemoteNotificationType typesset = (UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge);
if((types & typesset) == typesset)
{
    CeldaSwitch.chkSwitch.on = true;
}
else
{
    CeldaSwitch.chkSwitch.on = false;
}

在Xamarin,以上所有的解决方案都不适合我。 这是我用的:

public static bool IsRemoteNotificationsEnabled() {
    return UIApplication.SharedApplication.CurrentUserNotificationSettings.Types != UIUserNotificationType.None;
}

当你在设置中更改通知状态后,它也会得到实时更新。
