Make UIAlertView Button trigger function On Press

Question

Currently I am using the following code to present a UIAlertView:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@\"Today\'s Entry Complete\"

If you are using multiple UIAlertView instances that are not declared in the class's interface you can also set a tag to identify instances in your delegate method, for example:

somewhere on top of your class file myClass.m

#define myAlertViewsTag 0

creating the UIAlertView:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"My Alert"
    message:@"please press ok or cancel"
    delegate:self
    cancelButtonTitle:@"Cancel"
    otherButtonTitles:@"OK", nil];
alert.tag = myAlertViewsTag;
[alert show];
[alert release];

the delegate method:

-(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
    if (alertView.tag == myAlertViewsTag) {
        if (buttonIndex == 0) {
            // Do something when cancel pressed
        } else {
            // Do something for ok
        }
    } else {
        // Do something with responses from other alertViews
    }
}
