該頁(yè)面需要隱藏導(dǎo)航欄,你可能會(huì)這么設(shè)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(shè)置之后,push到下一個(gè)頁(yè)面,再滑動(dòng)返回的時(shí)候,會(huì)出現(xiàn)黑色不平話界面出現(xiàn)
正確的設(shè)置方法是
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:YES animated:animated];//開啟動(dòng)畫效果
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[self.navigationController setNavigationBarHidden:NO animated:animated];//開啟動(dòng)畫效果
}
