UIAlertView not responding to UIAlertViewDelegate

Question

I'm using logos for iPhone (MobileSubstrate addons), with a .h file for my

@interface MyClass : NSObject <UIAlertViewDelegate>

and the

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if(buttonIndex == 0) {

is in the .m, but nothing is working, when tapping the buttons on the alert, it doesn't invoke what I have set for each buttonIndex.

Thanks.

Edit: Here's what I've got;

#import "Tweak.h"

%hook ASApplicationPageHeaderView

- (void)_showPurchaseConfirmation {
    UIAlertView *alert = [[UIAlertView alloc] init];
    [alert setTitle:@"title"];
    [alert setMessage:@"message"];
    [alert setDelegate:self];
    [alert addButtonWithTitle:@"button 1"];
    [alert addButtonWithTitle:@"continue"];
    [alert show];
    [alert release];
}

- (void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex {    
    if (buttonIndex == 0) {  //also tried (UIAlertView *)alertView
        UIAlertView *lol = [[UIAlertView alloc] init];
        [lol setTitle:@"button 1"];
        [lol setMessage:@"button 1"];
        [lol setDelegate:self];
        [lol addButtonWithTitle:@"lol"];
        [lol show];
        [lol release];
    } else {
        %orig;
    }
}

%end

Answer 1

Define your alert within that class and declare the alert delegate to self hope it start working to you

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert View "
                      " 
                                                message:@"Would you like to do something?"
                                               delegate:self 
                                      cancelButtonTitle:@"Cancel"
                                      otherButtonTitles:@"Button1", @"Button2", nil];
[alert show];
[alert release];

You'll most likely need to register your class as the delegate at some point using something along the lines of:

 [yourAlertViewObject setDelegate:self];

As the UIAlertViewDelegate Protocol Reference docs say (emphasis mine):

If you add your own buttons or customize the behavior of an alert view, implement a delegate conforming to this protocol to handle the corresponding delegate messages. Use the delegate property of an alert view to specify one of your application objects as the delegate.

You just need to put %new in front of the alertView delegate:

 %new
 -(void) alertView:...
