Answer 1

I followed as talkol suggested

In my case I replaced following line

[myMutualArray removeAllObjects];

with

[myMutualArray removeAllObjects]; myMutualArray = nil;

And the error gone!

Answer 2

You are probably releasing an object too many times (for example, calling alloc once and release twice). To find out where, take a look at the techniques in this question: How to find the cause of a malloc "double free" error?

I personally like the NSZombieEnabled method.

Another tip, is to set your variables to nil after you release them.

For example: [bla release]; bla = nil;

This makes sure you will not accidentally release them twice since releasing nil does nothing.

Answer 3

Please test the program for memory leaks,also check autoreleases and whether you are releasing objects properly or not.Also we need to check whether a released object has a memory allocated or not.You also need to be careful regarding autorelease,because accidentally we might release an array or a string or any object that is already autoreleased...

Here are some of the tips to trace out the exact problem:

1. You can test for leaks by analyzing your project(click shift+command+k)

2. Use instruments tool i.e. running for leaks

3. Enable NSZombie in Xcode,procedure can be found here

Hope it helps and works!
