Object is not being deleted from NSMutableArray?

I have a NSMutableArray when I try to delete object from it, object is not being deleted. And when I debug my code there is data in it. Here is my code -

NSMutableArray *myArray = [array copy];
// array is NSArray which contains data

[myArray removeObjectAtIndex:0];

It will not delete object from this array because your NSMutableArray has become Immutable. You're making copy of NSArray instead of it make mutableCopy it will work - 

NSMutableArray *myArray = [array mutableCopy];

Or you can also use initWithArray: method.

NSMutableArray *myArray = [[NSMutableArray alloc] initWithArray:array];
