Answer 1

AlertView в Swift в ios8

var alert = UIAlertController(title: "Alert", message: "Message", preferredStyle: UIAlertControllerStyle.Alert) 
alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.Default, handler: nil)) 
self.presentViewController(alert, animated: true, completion: nil)

if ([UIAlertController class]) 
{ 
    // use UIAlertController 
    UIAlertController *alert= [UIAlertController 
            alertControllerWithTitle:@"Enter Folder Name" 
            message:@"Keep it short and sweet" 
            preferredStyle:UIAlertControllerStyleAlert]; 

    UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault 
               handler:^(UIAlertAction * action){ 
                //Do Some action here 


               }]; 
    UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault 
                handler:^(UIAlertAction * action) { 

                 NSLog(@"cancel btn"); 

                 [alert dismissViewControllerAnimated:YES completion:nil]; 

                }];
