Question

我有一个“FairListViewController”。这是第一个ViewController。在这里通过触摸tableCell，我可以转到下一个是“MenuViewController”。还有两个Button，“ProductViewController”的“Product”和“EventViewController”的“Events”。我在appDelegate中使用“NavigationController”作为“rootViewController”。现在，当我触摸“MenuViewController”中的“Product”按钮时，将我带到“ProductViewController”并触摸“BackButton”，它会顺利回到“MenuViewController”。我为“ProductViewController”做了相同的代码，这里它带我到“EventViewController”但是在触摸“BackButton”之后，奇怪的是它回到了First Page，即“FairListViewController”。我多次更改了我的IBAction按钮名称（在“EventViewController”nib文件中）的名称。重新连接nib文件，甚至从nib文件中删除按钮并尝试使用新按钮，但结果是一样的！以前任何人都可以类似这个问题。任何建议都会非常值得赞赏。非常感谢提前。

这是我的代码：

在MenuViewController中（对于ProductViewController按钮）：

- (IBAction)callProductGroups:(id)sender
{
ProductGroupViewController *productGroupViewController;

if(IS_IPHONE_5)
{
    productGroupViewController = [[ProductGroupViewController alloc] initWithNibName:@"ProductGroupViewController" bundle:nil];
}
else
{
    productGroupViewController = [[ProductGroupViewController alloc] initWithNibName:@"ProductGroupViewControlleriPhone4" bundle:nil];
}

productGroupViewController.topBarImageForAll = self.topBarImageForAll;
productGroupViewController.topBarButtonImageForAll = self.topBarButtonImageForAll;
productGroupViewController.buttonDividerImageForAll = self.buttonDividerImageForAll;
productGroupViewController.backgroundImageForAll = self.backgroundImageForAll;
productGroupViewController.backgroundImageiPhone4ForAll = self.backgroundImageiPhone4ForAll;

[self.navigationController pushViewController:productGroupViewController animated:YES];
}

在ProductViewController中：

-(IBAction)goBack:(id)sender
{
    [self.navigationController popViewControllerAnimated:YES];
}

在MenuViewController中（对于EventViewController按钮）：

- (IBAction)callEvents:(id)sender
{
EventViewController *eventViewController;

if (IS_IPHONE_5)
{
    eventViewController=[[EventViewController alloc] initWithNibName:@"EventViewController" bundle:nil];
}
else
{
    eventViewController=[[EventViewController alloc] initWithNibName:@"EventViewControlleriPhone4" bundle:nil];
}

eventViewController.topBarImageForAll = self.topBarImageForAll;
eventViewController.topBarButtonImageForAll = self.topBarButtonImageForAll;
eventViewController.buttonDividerImageForAll = self.buttonDividerImageForAll;
eventViewController.backgroundImageForAll = self.backgroundImageForAll;
eventViewController.backgroundImageiPhone4ForAll = self.backgroundImageiPhone4ForAll;

[self.navigationController pushViewController:eventViewController animated:YES];    
}

在EvenViewController中：

- (IBAction)backButton:(id)sender
{
    [self.navigationController popToRootViewControllerAnimated:YES];
}

[转到下一个ViewController没有问题，问题是关于回来。]

 Try instead of
    [self.navigationController popToRootViewControllerAnimated:YES]; 

Use
    [self.navigationController popViewControllerAnimated:YES];
