iOS中模态Model视图跳转和Push视图跳转的需求实现方法

/** 在C页面的DisMiss方法里面添加一下代码(iOS6.0+) */  if ([self respondsToSelector:@selector(presentingViewController)]){    [self.presentingViewController.presentingViewController dismissViewControllerAnimated:YES completion:nil];  }  else {    [self.parentViewController.parentViewController dismissViewControllerAnimated:YES completion:nil];  }

/** 这里用到的核心处理办法是 *//** 1.在A控制器模态Model推出B控制器的时候先给B控制器包装一个导航控制器 */UINavigationController *ANavigationController = [[UINavigationController alloc] initWithRootViewController:[[BViewController alloc] init]];[self presentViewController:ANavigationController animated:YES completion:nil];/** 2.在B控制器遵守UINavigationControllerDelegate实现代理协议,隐藏当前控制器的导航栏 */#pragma mark - UINavigationControllerDelegate- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {  // 判断要显示的控制器是否是自身控制器  BOOL isShowMyController = [viewController isKindOfClass:[self class]];  [self.navigationController setNavigationBarHidden:isShowMyController animated:YES];}#pragma mark - Push出C控制器[self.navigationController pushViewController:[[CViewController alloc] init] animated:YES];/** 3.在C控制器里面可直接在返回按钮方法里DisMiss */[self.navigationController dismissViewControllerAnimated:YES completion:nil];
