ios7 - 带有自定义后退按钮的滑动手势会卡住 Root View Controller

Question

我的应用程序中到处都是自定义后退按钮，看起来导航 Controller 不喜欢它。

所以，我希望 iOS7 滑动返回手势与我的自定义后退按钮一起使用。搜索并尝试了不同的方法，但似乎没有一个有希望。我能得到的最接近的是 http://keighl.com/post/ios7-interactive-pop-gesture-custom-back-button/ .
但是，现在当我继续推送和弹出导航堆栈时，一段时间后堆栈中的 rootViewController 停止响应任何触摸。

有什么建议？

就像 keighl 建议的那样，继承 UINavigationController 是正确的方法。但是他没有检查根 View Controller 以避免在根 View 上执行手势时卡住。
这是带有附加检查的修改版本:

CBNavigationController.h:

#import <UIKit/UIKit.h>

@interface CBNavigationController : UINavigationController <UIGestureRecognizerDelegate, UINavigationControllerDelegate>
@end

CBNavigationController.m:

#import "CBNavigationController.h"

@interface CBNavigationController ()
@end

@implementation CBNavigationController
- (void)viewDidLoad
{
    NSLog(@"%s",__FUNCTION__);
    __weak CBNavigationController *weakSelf = self;

    if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)])
    {
        self.interactivePopGestureRecognizer.delegate = weakSelf;
        self.delegate = weakSelf;
    }
}

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    NSLog(@"%s",__FUNCTION__);

    if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)])
        self.interactivePopGestureRecognizer.enabled = NO;

    [super pushViewController:viewController animated:animated];
}

#pragma mark UINavigationControllerDelegate

- (void)navigationController:(UINavigationController *)navigationController
       didShowViewController:(UIViewController *)viewController
                    animated:(BOOL)animate
{
    NSLog(@"%s",__FUNCTION__);

    // Enable the gesture again once the new controller is shown AND is not the root view controller
    if (viewController == self.viewControllers.firstObject)
    {
        if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)])
            self.interactivePopGestureRecognizer.enabled = NO;
    }
    else
    {
        if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)])
            self.interactivePopGestureRecognizer.enabled = YES;
    }
}

@end
