How to get custom delegate to work - ios

Question

I am creating a custom delegate UIAlertView's alert:buttonClickedAtIndex: method, but it is not working properly. I am subclassing a UIView, and I have two buttons that are tagged as 0 and 1. This still does not work when I go to check the delegate for my custom view. Here the code that I did.
Custom View
- (void) buttonTouchedWithIdentifier:(NSInteger)identifier
{
if (identifier == 0) {
[self.delegate alert:self didClickButtonWithTagIdentifier:0];
}
if (identifier == 1) {
[self.delegate alert:self didClickButtonWithTagIdentifier:1];
}
}
* in my showInViewMethod *
[self.dismissButton addTarget:self action:#selector(buttonTouchedWithIdentifier:) forControlEvents:UIControlEventTouchDown];
[self.continueButton addTarget:self action:#selector(buttonTouchedWithIdentifier:) forControlEvents:UIControlEventTouchDown];
self.dismissButton.tag = 0;
self.continueButton.tag = 1;
* in my view controller *
nextLevelAlert = [[ARAlert alloc] init];
nextLevelAlert.delegate = self;
[nextLevelAlert showInView:self.view
withMessage:[NSString stringWithFormat:#"Congratulations, you have completed level %i.\nWould you like to continue?", levelNumber]
dismissButtonTitle:#"Menu"
continueButtonTitle:#"Next Level"];
- (void)alert:(ARAlert *)alert didClickButtonWithTagIdentifier:(NSInteger)tagId
{
if (alert == nextLevelAlert) {
if (tagId == 0) {
NSLog(#"User does not want to continue.");
}
}
}
Now, nextLevelAlert has the delegate set to self, and I do have the delegate declared in my view controller's class. Also, when i do the showInView... for nextLevelAlert, it DOES appear, it is recognizing what button is being pressed.

My guess is your param is not a NSInteger but the button, you should change buttonTouchedWithIdentifier like this :
- (void) buttonTouchedWithIdentifier:(id)sender
{
UIButton *button = (UIButton*)sender;
NSLog(#"buttonTouchedWithIdentifier %#",#(button.tag));
if (button.tag == 0) {
[self.delegate alert:self didClickButtonWithTagIdentifier:0];
}
if (button.tag == 1) {
[self.delegate alert:self didClickButtonWithTagIdentifier:1];
}
}
Also when comparing two objects use isEqual: instead of ==
- (void)alert:(ARAlert *)alert didClickButtonWithTagIdentifier:(NSInteger)tagId
{
if ([alert isEqual:nextLevelAlert]) {
if (tagId == 0) {
NSLog(#"User does not want to continue.");
}
}
}
