Question

我可以在不使用这样的代码的情况下从导航 Controller 堆栈中删除 View Controller 吗

[mynavigationController popViewControllerAnimated:YES];

我们将不胜感激。

Answer 1

@rishi 几乎做到了。您需要一个可变数组来进行编辑

NSMutableArray *activeControllerArray = 
    [self.navigationController.viewControllers mutableCopy];

[activeControllerArray removeObjectAtIndex:indexToRemove];
// If you still have a handle to the viewcontroller you could use other methods like removeObject:

self.navigationController.viewControllers = activeControllerArray;

片段来自 UINavigationController docs

@property(nonatomic, copy) NSArray *viewControllers

... Assigning a new array of view controllers to this property is equivalent to calling the setViewControllers:animated: method with the animated parameter set to NO.
