视图侧滑返回上一级视图手势控制的开启(默认开启状态)与关闭控制,具体 code 如下:
作用域可以在所需视图的 viewDidAppear 和 viewWillDisappear 中进行对其控制;

开启侧滑返回

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

关闭侧滑返回

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

代理相关 UIGestureRecognizerDelegate

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
    if (gestureRecognizer == self.navigationController.interactivePopGestureRecognizer) {
        NSLog(@"AAAAAA --- %ld", [self.navigationController.viewControllers count]);// visibleViewController
        if (self.navigationController.viewControllers.count < 2 || self.navigationController.visibleViewController == self.navigationController.viewControllers.firstObject) {
            return NO;
        } else {
            return NO;
        }
    } else {
        return YES;
    }
}
