如果手動(dòng)定制了返回按鈕，右滑的手勢將會(huì)失效，也就是自定義了 navigationItem 的 leftBarButtonItem，右滑的手勢就會(huì)失效，解決方法如下：

@interface BaseNavigationController() < UIGestureRecognizerDelegate>

@end

@implementation BaseNavigationController

#pragma mark - Controller life cycle
- (void)viewDidLoad {
    [super viewDidLoad];
    self.interactivePopGestureRecognizer.delegate = self;
}

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
    return YES;
}
