Cellular Data for Podcasts pop-up - how to get rid of (iOS7)

Question

I am downloading all of my podcasts to my iPhone 4 (iOS7) through iTunes on my iMac. Before iOS7, I did this and listened to them in the Music app - it was all really straightforward. iOS7 forces me to use the Podcast app. I'm still not sure if I'd doing the sync/download from iTunes correctly as sometimes the episodes appear on the phone and sometimes they don't (and I'm the one who usually figures these things out and tells my other family members how to do it), but that's a whole different story.
Because I do not want any podcasts automatically downloaded to the phone, especially over Verizon's network, I turned off Settings -> Podcasts -> Use Cellular Data. I have also turned off Sync Subscriptions.
Whenever I am not on a WiFi network and I unlock my phone while it is in the Podcast app, I get a popup that says:
Cellular Data is Turned Off for "Podcasts"
You can turn on cellular data for this app in Settings.
And I have to "OK" it to make it disappear. It is getting annoying. I know cellular data is off. I did it on purpose.
My goal is to get rid of the popup but I've had no luck yet after tweaking a few settings. I don't know exactly what Sync Subscriptions does, but one educated guess is that as long as I have that off, no podcasts will be downloaded to the phone unless I do so via iTunes on my iMac. Is that correct, and would that allow me to turn on Use Cellular Data (to get rid of the popup)?
Any other ideas about this?
And if someone can explain all of the different permutations of how to manage Podcasts between iTunes and an iDevice (or even when a computer isn't in the picture), I'm all ears.

None of the tips suggested above worked for me. I still had that infernal message about connecting to the internet. But I have apparently (crossing my fingers) found a solution which works for me.
In the good old days I had iOS6 on my iPhone 5 with iTunes 10. I created a Podcast playlist in iTunes and I could cheerfully listen to it on the Music app driving around Europe (I'm on a UK tariff) with no 3G or wifi.
I now use iOS7 on my iPhone 5, syncing with iTunes 11 on Mavericks. I can now listen to the same Podcast Playlist with the Podcast app, wifi and Cellular Data turned off, Cellular Data and Notifications turned on everywhere and not a trace of the warning message. All the Podcasts play in sequence with no problem. Victory?!
The problem turned out to be in the syncing with iTunes. Although the Podcasts, whether in the Playlist or not, appeared to be syncing, in fact they were not imported fully into the phone. Thus when I selected a Podcast to play, the full file wasn't actually on the phone and so it wanted to stream it.
My solution was achieved by doing the following.
1. Create Podcast playlist in iTunes and drag some podcasts into it.
2. Wiith phone connected to iTunes device, highlight the iPhone in the left hand column and swivel the little arrow to expand the list of contents. You can then check the actual contents of each section on the phone. Music, Movies, TV Shows, Podcasts etc.
3. Hit iPhone in left hand column. Hit Podcasts tab at top of window. Uncheck everything in and out of sight and Apply/Sync to remove all Podcasts from phone.
4. Hit Podcasts section of expanded iPhone contents list in left hand column. That should be empty. Similarly there should be no sign of the Podcast playlist below it.
5. Now return to the Podcasts syncing section. Check 'Sync Podcasts'.
6. Scroll to bottom of page to 'Include Episodes from Playlists' and check the Podcast playlist you created. Apply/Sync.
7. Now check that the Podcasts in the playlist are in the phone by hitting the Podcast label in the expanded contents list. It should match the contents of the Playlist which should also have appeared in the list of playlists in the phone.
8. With WiFi and Cellular Data turned off, go to Podcast app and, if you're as lucky as me, you should be able to play any of the Podcasts in the playlist without that infernal message being displayed. Displaying 1 or 2 fingers at your mobile provider is optional!
