Error: *** -[CALayer retain]: message sent to deallocated instance 0xdaa54d0


I am working on simple iphone application. where i am working on two views. I pushed the other view controller first and when i am removing the current view as to go back to the old view controller i am getting [CALayer retain]. EXEC_BAD_ACCESS.

In gdb, i tried backtrace command to see the problem which i have given below, but i am not able to find any. If anyone can help me out with this it will be great.

(gdb) backtrace

  • Sounds like you're also explicitly releasing something that you've already autoreleased.
