There is a MFI device that is connected to iPhone 4S (6.0 GM) or to iPad (6.0 GM) via Bluetooth (2.1 + EDR). The project was built on Xcode 4.5 GM. When the app gets EAAccessoryDidDisconnectNotification
it will send message [_eaSessionController closeSession];
. All these worked nice in iOS 5.1.1 or earler. But on iOS6 with this message I got logs as follows:
-[NSCondition dealloc]: condition (<NSCondition: 0x2e5640> '(null)') deallocated while still in use
Break on _NSLockError() to debug.
Any ideas?
There is no such trouble in iOS 6.1+. To fix this for iOS 6.0 and iOS 6.0.1 please use next solution:
Please note: this is only temp solution allow your users with iOS 6.0 and 6.0.1 continue use your app.
There is a simple hack to avoid application crashes: just create new category and override dealloc method (NSCondition) for iOS 6.0 and iOS 6.0.1:
This solution make new leak, after 20 min tests and about 50 BG/FG swithces instruments shows 10 NSCondition leaks (960 Bytes), BUT no one crash!
