Should i release nsstring

One consideration here, though, is when your controller might dispose of its user interface and reload it dynamically on demand for example, if you have a view controller that loads a view from a nib file, but on request -- say under memory pressure -- releases it, with the expectation that it can be reloaded if the view is needed again.

In this situation, you want to make sure that when the main view is disposed of you also relinquish ownership of any other outlets so that they too can be deallocated. Unfortunately this gives rise to a further issue. Because UIViewController currently implements its dealloc method using the setView: accessor method rather than simply releasing the variable directly , self. This will lead to a crash in dealloc.

The remedy is to ensure that outlet variables are also set to nil in dealloc :. Your code is failing because you have too many global references to objects that have not been released back into the memory pool. Sign up or log in Sign up using Google. Sign up using Facebook.
