buttonIndex in UIAlertController

[qiaoyan]

buttonIndex = -1 when click cancel button, buttonIndex = 0 when click other button. So current workaround way is [buttonIndex+1]

[UIAlertController KDI_presentAlertControllerWithTitle:@"Sign Out?" message:nil cancelButtonTitle:@"Cancel" otherButtonTitles:@[@"Sign Out"] completion:^(__kindof UIAlertController * _Nonnull alertController, NSInteger buttonIndex) {
if (alertController.actions[buttonIndex+1].style != UIAlertActionStyleCancel) {
//do something
}
}];

What specifically is the issue? If you want to know whether the cancel button was tapped check for KDIUIAlertControllerCancelButtonIndex within the completion block.

if (buttonIndex == KDIUIAlertControllerCancelButtonIndex) {
    // cancel button was tapped
}
else {
    // check other indexes, starting at 0 - (count of other titles - 1)
}
