Question

I have a simple question for you… I was reading Beginning IOS 4 Development book and there is the following code example:

UIAlertView *alert = [[UIAlertView alloc]
                              initWithTitle:@”Hello”
                                    message:@”This is an alert view”
                                   delegate:self
                          cancelButtonTitle:@”OK”
                          otherButtonTitles:nil];
[alert show];
[alert release];

Then it points out that the show message shows the alert view but the code does not stop it’s execution until the user dismisses the dialog, it goes on and executes the following code… since next to the show message there is a release message, does the show method retain the view until it is dismissed? Otherwise I should not release it after the show message has been sent.. I’m sorry but I did not find this information on the reference pages, so I hope this is not a (too much) stupid question.

OT: how do I activate colors on code snippets?

Answer 1

The window that displays the alert view retains its reference, so you don’t have to.
