添加 performSegueWithIdentifier() 调用后，会创建两个不同的 segue

Question

我在单击按钮时使用 performSegueWithIdentifier()，以便将正确的信息传递给下一个 ViewController。当我单击该按钮时，它会移动到一个新的视图空白视图，然后使用 performSegueWithIdentifier() 调用提供的信息打开我想要的视图。这需要用户点击返回按钮 2 次才能返回主视图。

有没有办法确保因为我使用 performSegueWithIdentifier() 而不会自动调用 prepareForSegue()？我感觉这种情况正在发生，因为我使用 performSegueWithIdentifier() 调用调用 prepareForSegue()，然后自动第二次调用它。

这是我使用 performSegueWithIdentifier() 方法的代码：

if (page == 1)
    [self performSegueWithIdentifier:@"time1" sender:self];
else if (page == 2
    [self performSegueWithIdentifier:@"time2" sender:self];
else if (page == 3)
    [self performSegueWithIdentifier:@"time3" sender:self];
else if (page == 4)
    [self performSegueWithIdentifier:@"time4" sender:self];
else if (page == 5)
    [self performSegueWithIdentifier:@"time5" sender:self];
else if (page == 6)
    [self performSegueWithIdentifier:@"time6" sender:self];
else if (page == 7)
    [self performSegueWithIdentifier:@"time7" sender:self];
else if (page == 8)
    [self performSegueWithIdentifier:@"time8" sender:self];
else if (page == 9)
    [self performSegueWithIdentifier:@"time9" sender:self];
else if (page == 10)
    [self performSegueWithIdentifier:@"time10" sender:self];
else if (page == 11)
    [self performSegueWithIdentifier:@"time11" sender:self];
else if (page == 12)
    [self performSegueWithIdentifier:@"time12" sender:self];
else if (page == 13)
    [self performSegueWithIdentifier:@"time13" sender:self];

这是我的 prepareForSegue() 方法：

- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"time1"] ||
        [segue.identifier isEqualToString:@"time2"] ||
        [segue.identifier isEqualToString:@"time3"] ||
        [segue.identifier isEqualToString:@"time4"] ||
        [segue.identifier isEqualToString:@"time5"] ||
        [segue.identifier isEqualToString:@"time6"] ||
        [segue.identifier isEqualToString:@"time7"] ||
        [segue.identifier isEqualToString:@"time8"] ||
        [segue.identifier isEqualToString:@"time9"] ||
        [segue.identifier isEqualToString:@"time10"] ||
        [segue.identifier isEqualToString:@"time11"] ||
        [segue.identifier isEqualToString:@"time12"] ||
        [segue.identifier isEqualToString:@"time13"])
    {
        InfoViewController *ivc = [segue destinationViewController];
        if (_stringText != nil)
            ivc.viewText = _stringText;
    }//end if
}//end prepareForSegue

您正在执行哪些操作？你的 performSegueWithIdentifier 方法不应该调用自己，这绝对是你得到两个后退按钮的原因。你在故事板中也有这个吗？如果您在情节提要中设置了转场，您甚至可能根本不需要 performSegueWithIdentifier 调用，然后您只需为每个转场做准备。
