iOS禁用边缘侧滑返回

进入该页面时，关闭侧滑手势：

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    if([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = NO;
    }
}

进入下个页面或者返回上一个页面时，启用侧滑手势：

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    if([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
    }
}
