推荐答案
案例1 ：放松Segue
根据您的具体情况，这将完美无缺：
This will work perfect according to your situation:
Unwind Segues为您提供了一种展开导航堆栈并指定要返回的目的地的方法。
Unwind Segues give you a way to "unwind" the navigation stack and specify a destination to go back to.
案例2 ：PopToRootViewController
Case 2 : PopToRootViewController
如果您的父视图也是您的根视图控制器，然后您可以使用轻松取回popToRootViewControllerAnimated：YES 。
If you Parent view is also your Root view controller, then you can easily get back using popToRootViewControllerAnimated:YES.
创建自己的后退按钮将其添加到导航栏方法 backButtonTouch 。
Create own back button add it to navigation bar with method backButtonTouch.
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back", nil) style:UIBarButtonItemStyleDone target:self action:@selector(backButtonTouch:)];
将以上代码添加到 viewDidLoad 。
-(void)backButtonTouch:(id)sender{
[self.navigationController popToRootViewControllerAnimated:YES];
}
