Question

I have an app that used to accept push notifications without any issues but since I upgraded to a 4s, I’m noticing that sending a push while the app is not in the foreground locks my screen. The moment I send the push, my phone’s screen goes blank with a spinner and then the lock screen keyboard comes up. Anybody have any idea why this is happening? My friend who has a iphone 4 on ios4 seems to be getting the pushes fine. This seems like a something that should not even be possible because it could be abused by rogue app developers

I just ran into this myself. This is what a normal alert looks like:

{
     "aps" : { "alert" : "This is the alert text", "badge" : 1, "sound" : "default" }
}

I was sending “sound”:”” and got the exact same bug you were getting. If you do not want to send a sound with your message, don’t send the sound bit at all.

bad:
{
“aps” : { “alert” : “This is the alert text”, “badge” : 1, “sound” : “” }
}

good:
{
“aps” : { “alert” : “This is the alert text”, “badge” : 1 }
}
