UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Save" 
                 message:@"Enter File Name" 
                 delegate:self 
               cancelButtonTitle:@"Cancel" 
               otherButtonTitles:@"OK", nil]; 

    alertView.alertViewStyle = UIAlertViewStylePlainTextInput; 

    [alertView show]; 



- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex 
{ 
    NSLog(@"Alert View dismissed with button at index %d",buttonIndex); 

    switch (alertView.alertViewStyle) 
    { 
     case UIAlertViewStylePlainTextInput: 
     { 
      UITextField *textField = [alertView textFieldAtIndex:0]; 
      NSLog(@"Plain text input: %@",textField.text); 
     } 
      break; 

     case UIAlertViewStyleSecureTextInput: 
     { 
      UITextField *textField = [alertView textFieldAtIndex:0]; 
      NSLog(@"Secure text input: %@",textField.text); 
     } 
      break; 

     case UIAlertViewStyleLoginAndPasswordInput: 
     { 
      UITextField *loginField = [alertView textFieldAtIndex:0]; 
      NSLog(@"Login input: %@",loginField.text); 

      UITextField *passwordField = [alertView textFieldAtIndex:1]; 
      NSLog(@"Password input: %@",passwordField.text); 
     } 
      break; 

     default: 
      break; 
    } 
}
