該頁面需要隱藏導航欄,你可能會這么設置
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
self.navigationController.navigationBarHidden = YES;
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
self.navigationController.navigationBarHidden = NO;
}
然而如此設置之后,push到下一個頁面,再滑動返回的時候,會出現黑色不平話界面出現
正確的設置方法是
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:YES animated:animated];//開啟動畫效果
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[self.navigationController setNavigationBarHidden:NO animated:animated];//開啟動畫效果
}
