SKPaymentQueue addTransactionObserver asking for App Store password on startup after in-app purchase

I have a problem, when I loadStore in app purchase I add a transaction observer, the problem is that when I add the observer I get a message开发者_开发问答 to sign in to the itunes store, to buy something, does it may be that last transactions didn't finished?

I had this problem, which was fixed by calling finishTransaction: on the payment queue. Without this the transaction persists like a lost phantom.

Actually, I'm having the same problem... But I can tell you that it only happens on ONE of my iPads, and not the other. (They were both 4.3.3).

Sign in to the iTunes Store

Silly apple, how can I test my app if I'm logged into iTunes?

But even if I login (Buy), this dialog appears EVERYTIME launch my app and fetch my product description. THEN, I see my sandbox login.

Tried a restore, and it disappeared for the first run. Perplexing...

LATER:
It seems that restoring the device (3 times) has fixed the problem. I wish I had a more concrete answer for you. But it worked for me.

MUCH LATER: Yup. Signing-in every time when prompted by Apple did the trick. I eventually caught up with my backlog of incomplete transactions. (And deleting my old test accounts in iTunes seemed to be a faster way to accomplish the same thing.)
