My test app loads a UITableView and crash caused by [1421:12503] *** -[__NSArrayM class]: message sent to deallocated instance 0x10ae83e0. Process stopped at main()
I'm guessing that the NSArray you are using for the data source is autoreleased. Check it out and retain it. That will probably fix this, but I can't really be sure without some code, especially on how you are creating this array.
Don't forget to release the array in dealloc when you're done.
