Object allocations instrument on iphone

I have problem with the way I treat the memory management in iphone..please please help me..I am running out of ideas..I tried to play with the below method but it started leaks when I am trying to allocate the strings for the objects (for example allocation for sid,first_name etc)..I can't figure out how to do..and this is the method where I will get all the contacts from the service and insert it into the database..It consumes more memory which I figured out by running allocations instrument on iphone and my app on iphone crashes..please please help me guys..What is the better solution for it..I think my app consumes more memory but not sure where to look into it..I can post any code if this is not clear..thanks a lot!!!

EDIT:

I got rid of all the leaks but can any one please tell me how to check the object allocations instrument in iphone..Please see the below screenshot..My app gets crashed once it loads all the 4200 contacts and the contacts are never displayed on the table view..What might be the problem..I make sure that the place from which my contacts is saved to the database is leak free..In the below screenshot what exactly should I look for..is it the total allocation or living..please let me know guys..I am totally exhausted..thanks a lot for your time..

You should put the [string release]; lines inside the for(NSString * myStr in result.entry_list) loop. Each time you call alloc, there must be a corresponding release call.

A better way to do it is to use [NSString stringWithFormat:] instead of [[NSString alloc] initWithFormat:] so that you don't need to release them manually.

My app gets crashed once it loads all the 4200 contacts and the contacts are never displayed on the table viewnever displayed on the table view

4200 contacts make your loop "large and tight". As suggested by taskinoor, you can create and drain an NSAutoreleasePool for every a few loops to reduce memory foot print. For example:

int counter = 0;
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
for (...) {
    if (++counter == 100) {
        counter = 0;
        [pool release];
        pool = [[NSAutoreleasePool alloc] init];
    }
  //busy working...
}
[pool release];

Your app may also be terminated by iOS if it takes too long to respond to system events. This mechanism is know as watchdog timeout. In this case, you'll find the exception code 0x8badf00d in the crash report. You may want to break the work into smaller batches or use a secondary thread so that the main thread won't be busy for too long.

This is a long code and may be I'm wrong. But my guess is this .

for(NSString * myStr in result.entry_list) {
    // lots of alloc
}
// releases in this point

Now if you have more than one entry in result.entry_list (which I guess you have), aren't you leaking the strings? Say you have alloced str in 1st pass and in the 2nd pass during next alloc you are leaking this. Got my point?

If this is the problem, then you should move the release calls inside the loop.

Another solution is that it seems that you don't need the strings outside this scope. So why don't you use autorealse method to create it?

str = [NSString stringWithFormat:@"what_you_need"];

You don't need to release them now. Though in this case you should consider creating your own autorelease pool as the amount of data might be huge.
