I have a UIButton that is added to a tableview programmatically. The problem is that when it is touched I run into the unrecognized selector sent to instance error message.
UIButton *alertButton = [UIButton buttonWithType:UIButtonTypeInfoDark];
[alertButton addTarget:self.tableView action:@selector(showAlert:)
forControlEvents:UIControlEventTouchUpInside];
alertButton.frame = CGRectMake(220.0, 20.0, 160.0, 40.0);
[self.tableView addSubview:alertButton];
and here's the alert method which I want to trigger when the InfoDark UIButton is touched:
- (void) showAlert {
UIAlertView *alert =
[[UIAlertView alloc] initWithTitle:@"My App"
message: @"Welcome to ******. \n\nSome Message........"
delegate:nil
cancelButtonTitle:@"Dismiss"
otherButtonTitles:nil];
[alert show];
[alert release];
}
thanks for any help.
Ok you have two problems. one is the selector issue as stated above, but your real problem is:
[alertButton addTarget:self.tableView
action:@selector(showAlert:)
forControlEvents:UIControlEventTouchUpInside];
This is the wrong target, unless you have subclassed UITableView to respond to the alert.
you want to change that code to:
[alertButton addTarget:self
action:@selector(showAlert)
forControlEvents:UIControlEventTouchUpInside];
