ios - 添加performSegueWithIdentifier()调用后，将创建两个不同的segue

单击按钮时，我正在使用performSegueWithIdentifier()，以便可以将正确的信息传递给下一个ViewController。当我单击按钮时，它将移至新视图空白视图，然后使用performSegueWithIdentifier()调用提供的信息打开所需的视图。这就要求用户单击两次“后退”按钮只是为了返回主视图。

有没有一种方法可以确保由于我使用performSegueWithIdentifier()而不会自动调用prepareForSegue()？我有这种感觉，因为我用performSegueWithIdentifier()调用了prepareForSegue()，然后第二次被自动调用。

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

最佳答案

您正在采取什么动作？您执行performSegueWithIdentifier方法不应该调用自身，这绝对是为什么您要获得两个后退按钮的原因。您是否也将其连接到情节提要中？如果在情节提要中设置了脚本，则可能甚至根本不需要PerformSegueWithIdentifier调用，然后为每个脚本准备ForSegue。
