dismissViewControllerAnimated:completion:推送到另一个ViewController

Question

我只是想知道在我解雇之后是否可以推送到ViewController.

我一直在尝试这个:

     -(void)dismiss{
    //send information to database here

    [self dismissViewControllerAnimated:YES completion:^{
                    NSLog(@"Dismiss completed");
                    [self pushtoSingle:post_id];
                }];
}

-(void)pushtoSingle:(int)post_id{
    Single1ViewController *svc = [self.storyboard instantiateViewControllerWithIdentifier:@"SingleView"];
    svc.post_id = post_id;
    svc.page = 998;
    [self.navigationController pushViewController:svc animated:YES];
}

还有这个:

    -(void)dismiss{

//send information to database here

[self dismissViewControllerAnimated:YES completion:^{
                    NSLog(@"Dismiss completed");
                    Single1ViewController *svc = [self.storyboard instantiateViewControllerWithIdentifier:@"SingleView"];
                    svc.post_id = post_id;
                    svc.page = 998;
                    [self.navigationController pushViewController:svc animated:YES];
                }];
}

但没有成功.视图成功被取消,但推送从未初始化.是否有其他已知方法解决问题？

Answer 1

是的,我明白了.在我将ViewController B解除为A然后在A中收到通知并推送到C之后,我只是发布了一个通知.

解雇B:

[self dismissViewControllerAnimated:YES completion:^{

    [[NSNotificationCenter defaultCenter] postNotificationName:@"pushToSingle" object:nil userInfo:[NSDictionary dictionaryWithObject:[NSNumber numberWithInt:post_id1] forKey:@"post_id"]];
}];

在A中接收:

-(void)viewWillAppear:(BOOL)animated{   
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(pushToSingle:) name:@"pushToSingle" object:nil];
}

-(void)pushToSingle:(NSNotification *)notis{
    NSDictionary *dict = notis.userInfo;
    int post_id = [[dict objectForKey:@"post_id"] intValue];

    NSLog(@"pushing to single");
    Single1ViewController *svc = [self.storyboard instantiateViewControllerWithIdentifier:@"SingleView"];
    svc.post_id = post_id;
    svc.page = 998;
    [self.navigationController pushViewController:svc animated:YES];

}

谢谢,Jacky Boy!
