I am getting this exception:
malloc: *** error for object 0x754cab0: double free
*** set a breakpoint in malloc_error_break to debug
Program received signal: “SIGABRT”.
I don’t know why it was generated only in Iphone sdk 4.0 (device and simulator), but it was not generated in Iphone sdk 3.0 versions (device and simulator).
Can anyone tell me what is going wrong so that I can update my app?
It tells you what the problem is: You are free’ing memory when it has already been done, probably by sending too many release messages to an object.
Run in debug mode and it will probably stop right away at the correct line of code. Then, trace back what you do that object.
