注意hidesBottomBarWhenPushed调用的时机,是在push方法调用之前调用
简单的处理方式,自定义UINavigationController重写push方法,把下面的代码放进去即可
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{
NSArray *viewControllers = self.viewControllers;
if (viewControllers.count == 0) {
viewController.hidesBottomBarWhenPushed = NO;
} else {
viewController.hidesBottomBarWhenPushed = YES;
}
// 必须在super之前执行hidesBottomBarWhenPushed
[super pushViewController:viewController animated:animated];
}
