////導航欄背景透明
[self.navigationController.navigationBar setBackgroundImage:[UIImage new] forBarMetrics:UIBarMetricsDefault];
//導航欄底部線清楚
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
self.navigationController.navigationBar.translucent = YES;
[self.navigationController.navigationBar setShadowImage:[UIImage new]];
將導航設爲透明後,再push跳轉的頁面導航欄也是透明的,該怎麼改啊
