EDIT:
Problem Solved ==> Simply giving a tag solved the problem.
I have the following problem:
On a view I have two UIalertviews:
NSString *message = [NSString stringWithFormat:#"Users must enter this code to join the meeting: %#", meetingCode];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Meeting code"
message:message
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:#"Copy to clipboard", nil];
[alert show];
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex == [alertView cancelButtonIndex])
{
NSLog(#"Code not copied");
}
else
{
UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
pasteboard.string = meetingCode;
NSLog(#"Code copied");
}
}
and this one:
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
AgendaModel* agenda = _meeting.agenda[indexPath.row] ;
NSDictionary *dict = [[NSDictionary alloc] initWithObjectsAndKeys:agenda.id,#"id",agenda.name,#"name", nil];
NSString *message = [NSString stringWithFormat:#"Are you sure that you want to delete : %#?", agenda.name];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Warning"
message:message
delegate:self
cancelButtonTitle:#"Close"
otherButtonTitles:#"Delete", nil];
[alert show];
NSString *delete_url = [NSString stringWithFormat:#"RestAgendas/delete.json"];
[_meeting.agenda removeObject:agenda];
[self.tableView deleteRowsAtIndexPaths:[NSMutableArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
[JSONAPI getWithPath:delete_url andParams:dict completion:^(id json, JSONModelError *err) {
NSLog(#"%#", json);
}];
}
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex == [alertView cancelButtonIndex])
{
NSLog(#"Agenda Won't Be Deleted");
}
else
{
NSLog(#"Agenda Will Be Deleted");
}
}
Now is the problem that I got the error: Duplicate declaration of method 'alertView:clickedButtonAtIndex'
How can I fix this? I tried some stuff I found here but I still can't make it work. Can someone help me?

Yep, like you said, giving a tag allows you to have multiple UIAlertView in one single view.
Same goes for UIActionSheet or UIAlertController
for future reference, even though this is probably a duplicate, simply create your alert like usual and add
myAlert.tag = 123; //any number of your choice
and in alertView:clickedButtonAtIndex
you can find it using a switch or some if's
if (alertview.tag = 123){
// this is my alert
}else if(alertview.tag = 333){
// this is my other alert
}
For what it's worth, I suggest using else if and not just if to avoid the whole method to be read everytime, and order your if's by decreasing likeliness of being called.
Note you can also give tags to buttons, views, cells, labels, and just pretty much every outlet you can find.
