Thanks

Answer 1

You have probably tried to access an object which has been released. Search for "NSZombieEnabled" and read up on how to debug over-release problems.

Answer 2

The problem is you are over-releasing objects. Since you're using retain-properties you haven't to release the object when assigning a new object to the property. The old object will be released automatically. So these lines make no sense, delete them:
if (self.recipesArray != nil) {
// Release the arrays
[self.recipesArray release];
[self.recipesNames release];
}
In cellForRowAtIndexPath (RecipesListController) you are releasing rowString. There's no need to do that here. Delete that line and everything should work properly.

Answer 3

NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
self.recipesArray = dict;
[dict release];
in your RecipesListController.m file check 55 line in viewwill appear you are release the object that you never give memory
when i make comment to
//[self.recipesArray release];
//[self.recipesNames release];
then it crash on tableview row check it
