如果手动定制了返回按钮，右滑的手势将会失效，也就是自定义了 navigationItem 的 leftBarButtonItem，右滑的手势就会失效，解决方法如下：
@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;
}
