Fasttracks, try what Peter suggested. The problem is loading it all at once, since you have about 20 MB available for your own app, i believe. If you'd use a NSInputStream, you can load it in pieces, due to which you wont fill up the entire memory at once. Also read this answer to another question: Objective-C: Reading a file line by line

You haven't given code, but if you are using stringWithContentsOfFile to get an entire file consider using NSInputStream or stdio to read it and process or display it more incrementally.

Do you start reading the file from - (void) viewDidLoad? That might be the problem. Try start reading it in a different thread, like: [self performSelectorInBackground:@selector(method) withObject:nil];
