Memory leak?

I noticed strange memory behavior in my game. Each time after launch the game uses different amounts of memory. After loading of resources can be used from 60mb to 120mb, but if I suspend and resume the application, the memory is occupies 50 mb. Also after deleting of resources, the memory is not released completely. This is a memory leak or monkey error?

I'm glad you brought this up. How are you monitoring the memory? I'm not very familiar with XCode.

My game seems to grow more sluggish after each restart from a suspended state and it's making me a bit nervous that a memory leak is in there somewhere.

Run -> Profile, and then the Instruments will be waken up and you can choose between different monitor types.

In addition to the Profiler I also use this function

int ShowMem() 
{ 
//#ifdef DEBUG 
    struct task_basic_info info; 
    mach_msg_type_number_t size = sizeof(info); 
    /*kern_return_t kerr =*/ task_info(mach_task_self(), 
                                       TASK_BASIC_INFO, 
                                       (task_info_t)&info, 
                                       &size); 
    
    vm_statistics_data_t vmStats; 
    mach_msg_type_number_t infoCount = HOST_VM_INFO_COUNT; 
    
    host_statistics(mach_host_self(), HOST_VM_INFO, (host_info_t)&vmStats, &infoCount); 
    
    return info.resident_size/1048576;
    //NSLog(@"Memory in use (in bytes): %u", info.resident_size); 
//#endif 
}
