Why does this create a memory leak (iPhone)?

Question

//creates memory leak
  self.editMyObject = [[MyObject alloc] init];

//does not create memory leak
  MyObject *temp = [[MyObject alloc] init];
  self.editMyObject =         


        

Answer 1

Everyone else has already covered why it causes a memory leak, so I'll just chime in with how to avoid the 'temp' variable and still prevent a memory leak:

self.editMyObject = [[[MyObject alloc] init] autorelease];

This will leave your (retain) property as the sole owner of the new object. Exactly the same result as your second example, but without the temporary object.
