問題
A界面push到B界面艘刚，在B界面需要隱藏導(dǎo)航欄，直接使用self.navigationController.navigationBar.hidden = YES; 過渡動(dòng)畫明顯出現(xiàn)白板現(xiàn)象
解決方案
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:YES animated:animated];
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[self.navigationController setNavigationBarHidden:NO animated:animated];
}
