Say I have a alert view like follows in obj c
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"title" message:@"szMsg" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:@"download"];
[alert show];
[alert release];
Now we have 2 buttons on the alert view (Ok & Download), how to write an event handler for the Download one?
First you will need to add the UIAlertViewDelegate to your header file like below:
Header file (.h)
@interface YourViewController : UIViewController<UIAlertViewDelegate>
Implementation File (.m)
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"title" message:@"szMsg" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:@"download"];
[alert show];
[alert release];
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if (buttonIndex == 0)
{
//Code for OK button
}
if (buttonIndex == 1)
{
//Code for download button
}
}
