Question

我想在单击AlertView中的按钮后跳转到另一个viewController。谁能给我一个样品？

问题更新-------

我正在尝试这种方式：

- （void）tableView：（UITableView *）tableView didSelectRowAtIndexPath：（NSIndexPath *）indexPath {

UITableViewCell * cell = [self.tableView cellForRowAtIndexPath：indexPath];

if ([cell.reuseIdentifier isEqualToString:@"Logoff"]){


    UIAlertController* alert = [UIAlertController alertControllerWithTitle:nil
                                                                   message:@“Logoff？"
                                                            preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction* Confirm = [UIAlertAction actionWithTitle:@“Confirm" style:UIAlertActionStyleDefault
                                                    handler:^(UIAlertAction * action)

    {
        [alert dismissViewControllerAnimated:YES completion:nil];
        [self.performSegueWithIdentifier:@"ShowLoginView" sender:self];

        LoginViewController *newView = [self.storyboard instantiateViewControllerWithIdentifier:@"LoginViewController"];
        [self.navigationController pushViewController:newView animated:YES];
    }];
    UIAlertAction* Cancel = [UIAlertAction actionWithTitle:@“Cancel" style:UIAlertActionStyleDefault
                                                   handler:^(UIAlertAction * action) {}];

    [alert addAction:Confirm];

    [alert addAction:Cancel];
    [self presentViewController:alert animated:YES completion:nil];
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

}

但是我收到了这个错误：在'GeneralSettingsTableViewController *'类型的对象上找不到属性'performSegueWithIdentifier'

我错过了什么吗？

alertView折旧使用UIAlertController例如

 UIAlertController * alert=   [UIAlertController
                             alertControllerWithTitle:@"Info"
                             message:@"You are using UIAlertController"
                             preferredStyle:UIAlertControllerStyleAlert];

 UIAlertAction* ok = [UIAlertAction
                    actionWithTitle:@"OK"
                    style:UIAlertActionStyleDefault
                    handler:^(UIAlertAction * action)
                    {
                        [alert dismissViewControllerAnimated:YES completion:nil]; 
                    // here add your segue for navigation for another view Controller
            // If you already created the segue use this
            [self performSegueWithIdentifier:@"yoursegueName" sender:self];

          // if you are used Storyboard ID use this

             LoginViewController *newView = [self.storyboard instantiateViewControllerWithIdentifier:@"LoginViewController"];
[self.navigationController pushViewController:newView animated:YES];



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

                       }];

[alert addAction:ok];
[alert addAction:cancel];

[self presentViewController:alert animated:YES completion:nil];

尝试将传递控制传递给特定的viewController

- (void)viewDidLoad {
     [super viewDidLoad];
     [self showAlert];
}  

-(void)showAlert{
   UIAlertView *alertForCall = [[UIAlertView alloc]initWithTitle:@"" message:@"time to choose" delegate:self   cancelButtonTitle:@"NO" otherButtonTitles:@"Yes", nil];
     [alertForCall show];
}


-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    if (buttonIndex == 1){
          thirdViewController *thirdView = [self.storyboard instantiateViewControllerWithIdentifier:@"third"];
          [self.navigationController pushViewController:thirdView animated:YES];
   }
}
