how to get the message when receiving the “kCTMessageReceivedNotification” notification on IOS5

Here’s what I found … Just looking at the dumped private APIs, it looks like ChatKit.framework could help. Take a look at CKSMSService.h or CKMadridService.h for iMessage messages. I did quickly attempt to swizzle my own method in, for a couple methods in CKSMSService: – (void)_receivedMessage: (id)arg1 replace:(BOOL)arg2 replacedRecordIdentifier:(int)arg3 postInternalNotification:(BOOL)arg4; – (void)_receivedMessage: (id)arg1 replace:(BOOL)arg2 postInternalNotification:(BOOL)arg3; … Read more
