Do not press the NSAlert button while pressing the button

I am showing NSAlert with a custom view and three buttons. The user view has two text fields and allows the user to log in.

NSAlert with a similar design has appeared in the Mac App Store. When the user clicks the login button, NSAlert does not reject (until the credentials are verified). How does Apple support alerts?

Get NSButton that you want to behave differently. Change its purpose and action. (To go to the original goal / action, save them before changing them.)

 NSAlert *alert = ...; NSButton *button = [[alert buttons] objectAtIndex:...]; id oldTarget = [button target]; SEL oldAction = [button action]; [button setTarget:self]; [button setAction:@selector(verifyCredentials:)];

Alternatively, you can create an alert as a custom window controller and XIB (as Apple did in the case of the App Store). In this case, you have small-scale control over the behavior of the buttons.
