Complicated question here. I've successfully built an app utilizing BT and the UrbanAirship in app purchase module. I can make purchases and download the purchased content. This is really great for things like songs or pdf files. As a test, I created a pdf file as my content to purchase. Test purchase worked fine. It downloaded, and I was able to use the BT pdf option to access the file. Really cool. The content downloads to the directory 'Library/ua/downloads/<product_id>/<contents of zip file>' Now, here the question for the BuzzTouch and iOS gurus. What I'd like to do is create a BT_Plugin that is accessed from the main menu. It would check to see if the downloaded content exists. If it does, it would populate a submenu. If the content does not exist, it would open the store front viewer. I've set up 'myplugin.h' and 'myplugin.m' files in the BT_Plugins directory. I can access that file from the menu, but I'm not getting any success having it check if the downloaded file exists. Here's the .m code section: //does file exist + (void)initialize { NSString *productId = @jce.msu.buz; NSString *productDirectory = [kUADownloadDirectory stringByAppendingPathComponent:productId]; } +(BOOL)doesLocalFileExist:(NSString *)productDirectory{ BOOL success = FALSE; if(productDirectory != nil && [productDirectory length] > 1){ NSFileManager *fileManager = [NSFileManager defaultManager]; success = [fileManager fileExistsAtPath:[self getFilePath:productDirectory]]; if(success){ [BT_debugger showIt:self:[NSString stringWithFormat:@File does exist in directory: %@, fileName]]; success = TRUE; }else{ UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@loginRequired,@~ Login Required ~) message:NSLocalizedString(@NotPurchasedMessage, @You have not purchased this team. Please click the store button to purchase.) delegate:self cancelButtonTitle:NSLocalizedString(@ok, OK) otherButtonTitles:nil]; [alertView setTag:101]; [alertView show]; [alertView release]; //bail return; } } return success; } Anyone able to give me some help with this? Thanks.

So this is hard to fix? Bummer. I really want to create a app that will offer in app purchase. I´m gonna stick to this thread and hopefully I learn something.

If your in app purchase is something like a pdf book, mp3 file or image, it will work fine. Also, if you built out an html series of screens, that would probably work well too. I'm just trying to do something much more complicated. Hopefully someone has an answer or can point me in the right direction. It can't be that hard. I'm just not quite getting it.

I´m about to create a app with songs in it. But before I even start there I got like 8 new apps lined up calling for my attention :)

Hi Guys. MGoBlue's the guru! I'm a bit confused. In blue's setup, the document downloads to here: Library/ua/downloads/<product_id>/<contents of zip file> Is this intentional? Normally, downloads in a BT app go to the Documents directory (not the Library). If you download to the document directory you can use the built in BT method: +(BOOL)doesLocalFileExist:(NSString *)fileName in the BT_fileManager.m class. Like... if([BT_fileManager doesLocalFileExist:@mypdf.doc]){ ....show the menu of documents... }else{ ...show the store view cotnroller... } If building the menu of previously downloaded items, I can imagine doing a loop in the Documents directory and looking at each downloaded file. If all the downloaded purchases used a naming convention, like purchase_mydocument.pdf OR purchase_mysong.mp3 or whatever...you could search the file names in the Document's directory while you looped through the files and add only those that contained 'purchase_' to the menu. Lots of ways to do this I guess. Just trying to get my head around how it's working now.

Urban Airship's method downloads to the Library. I'll check out their docs and see how I can change the download destination. That may help. Thanks for the code suggestions. I'll check things out and get back to you.

Hi MGoBlue, wondering how your in app purchases are coming along....are you working out a container app for all your other apps? have something i am working on that i think is gonna need to do the same...what i would like to do is have one price for the container app and the apps inside the container app are free to download...any ideas and help are greatly appreciated :)

@Ian - I got busy on some other projects and haven't gotten back to this one yet. One of these days... It will probably help you with the app you emailed about.

Hi MGoBlue, got ur email...hope we can make this work...thanks!!! :)

I´m about to implement in app purchase now on one of my running apps. I'm gonna sell songs in the app. I'll let you know how it progresses and also I will try to make a manual for those interested. BR/Stefan

Awesome!!

Hi Stefan, any news? did work? I am very interested on your manual! :-)

Hi Stefan did you ever get around to the manual? Really interested how you made out....

Sorry guys! I've been occupied with other tasks so I haven't been looking into this at all. When I tried though I got stuck and I haven't been able to find a solution for it. BR/Stefan

Hey @MGoBlue, did you ever release an app with in-app purchasing? I wanted to see an example of someone getting that done with Buzztouch. Loved your push notifications tutorial. Would love to see an in app purchasing tutorial!

As you guys know quite a lot about how to implant an In-App Purchase I to an app, would any of you like to create a very quick and basic tutorial on how to do this. If you wouldn't mind, could you do it on my thread. There is a lot of heat on that thread already from people saying that they are subscribing and so on. It would be really beneficial to many members of Buzztouch. My thread is: http://www.buzztouch.com/forum/thread.php?tid=4ADE993C33279F5D30E4124&status=&searchInput=In-App%20Purchase&sortColumn=FT.dateStampUTC&sortUpDown=DESC¤tPage=1&doViews=1 Thanks, Annandale Apps

I would like to build in app purchases in my app. Basically I want to sell a webpage to my users which I am calling a premium feature. Does anyone have a step by step on this? Been reading everything on in-app but i just dont know where to start. Thanks Tony
