    <p>So I have autoreleased/released every object that I alloc/init/copy...and the allocations instrument seems to show minimal leaks...however...my program's memory usage does not stop increasing. I have included a screenshot of my allocations run (I have run allocations for longer but it remains relatively constant...it certainly does not compare to the amount the program gains when actually running. When running my program it will double in memory over the course of about 10 hours. The memory drastically increases in the first 5 minutes however (2-3MB), and just keeps on going. I don't understand why allocations would remain constant when running in instruments but my program would just keep gaining memory when actually run.</p> <p>Since I can't post images yet...here is the link to the screenshot:</p> <p><a href="http://dl.dropbox.com/u/2636863/Screen%20shot%202010-11-25%20at%2012.22.10%20PM.png" rel="nofollow">allocations run</a></p> <p>UPDATE: Here are some screenshots from my memory heapshot analysis...I am not allocating these objects explicitly and don't really know where they are coming from. Almost all of them have their source with something similar to the second screenshot details on the right (lots of HTTPs and URLs in the call tree). Anybody know where these are coming from? I know I've read about some NSURLConnection leaks but I have tried all of the cache clearing that those suggest to no avail. Thanks for all the help so far!</p> <p><a href="http://dl.dropbox.com/u/2636863/SS1.png" rel="nofollow">memory heap analysis 1</a></p> <p><a href="http://dl.dropbox.com/u/2636863/SS2.png" rel="nofollow">memory heap analysis 2</a></p>

    1. COWhat if you make the position of heapshot 1 your baseline and take your non-baseline heapshot some time after that? It looks pretty steady after that initial spike.

    2. COI have tried that and you are right the memory is relatively stable after that. There are still smaller but similar leaks almost every heapshot though.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
