是否有办法迅速进入<条码>。 我想从 st中删除所有观点;回到<条形码>。
第一,我认为你需要放弃所提出的模式,然后,你可以pop住所有被推论的控制器。 正如所介绍的模型不会在航行过程中。
[self dismissModalViewControllerAnimated:YES];
然后,你可以站出来观看控制器。
[self.navigationController popToRootViewController:YES];
From the docs:
popToRootViewControllerAnimated: Pops all the view controllers on the stack except the root view controller >and updates the display.
-(NSArray*)popToRootViewController Animated:BOOL)animated参数
估计:
将这一价值计算给YES以适应过渡。 通行证,如果您正在设置和装饰;在显示其观点之前先安装导航控制器。
回归价值:
一系列观点控制器从 st中挤出。
