Multiple UIAlertView; each with their own buttons and actions

Question

Im creating a view in Xcode 4.3 and im unsure how to specify multiple UIAlertView's that have their own buttons with separate actions. Currently, my alerts have their own buttons, but the same actions. Below is my code.

-(IBAction)altdev {
    UIAlertView *alert = [[UIAlertView alloc] 

                          initWithTitle:@"titleGoesHere"
                          message:@"messageGoesHere"
                          delegate:self
                          cancelButtonTitle:@"Cancel"
                          otherButtonTitles:@"Continue", nil];
[alert show];
}

-(IBAction)donate {
    UIAlertView *alert = [[UIAlertView alloc] 

                          initWithTitle:@"titleGoesHere"
                          message:@"messageGoesHere"
                          delegate:self
                          cancelButtonTitle:@"Cancel"
                          otherButtonTitles:@"Continue", nil];
    [alert show];
}

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 1) {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.examplesite1.com"]];
         }
}


-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 1) {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"examplesite2.com"]];
    }
}  

Thanks for any help!

There is a useful property tag for UIView(which UIAlertView subclass from). You can set different tag for each alert view.

UPDATE:

#define TAG_DEV 1
#define TAG_DONATE 2

- (IBAction)altdev {
    UIAlertView *alert = [[UIAlertView alloc] 

                          initWithTitle:@"titleGoesHere"
                          message:@"messageGoesHere"
                          delegate:self
                          cancelButtonTitle:@"Cancel"
                          otherButtonTitles:@"Continue", nil];
   alert.tag = TAG_DEV;
   [alert show];
}

- (IBAction)donate {
    UIAlertView *alert = [[UIAlertView alloc] 

                          initWithTitle:@"titleGoesHere"
                          message:@"messageGoesHere"
                          delegate:self
                          cancelButtonTitle:@"Cancel"
                          otherButtonTitles:@"Continue", nil];
    alert.tag = TAG_DONATE;
    [alert show];
}

-(void)alertView:(UIAlertView *)alertView
clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (alertView.tag == TAG_DEV) { // handle the altdev
      ...
    } else if (alertView.tag == TAG_DONATE){ // handle the donate

    }
}

easier & newer

UIAlertView *alert = [[UIAlertView alloc] init...
alert.tag = 1;

UIAlertView *alert = [[UIAlertView alloc] init...
alert.tag = 2;



- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    if(alertView.tag == 1) {
        // first alert...
    } else  {
        // sec alert...
    }
}

all done!

If you find it dificult to use delegate methods to differently identifying alert view Then you can also use This Category class to use completion Block for each AlertView.

Alert_ActionSheetWithBlocks

For eg.

UIAlertView* alert1 = [[UIAlertView alloc] initWithTitle:@"AlertView+Block 1" message:@"WithBlocks" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];

[alert1 showWithFinishBlock:^(UIAlertView *alertView, NSInteger buttonIndex){ //--AlertView1 Stuff here }];

UIAlertView* alert2 = [[UIAlertView alloc] initWithTitle:@"AlertView+Block 2" message:@"WithBlocks" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
[alert2 showWithFinishBlock:^(UIAlertView *alertView, NSInteger buttonIndex){ //--AlertView2 Stuff here }];

I hope this one is the more easiest way as compare to tag + delegate method..
