Question

ios 判断控制器vc是不是present出来的

Answer 1

-(void)viewDidDisappear:(BOOL)animated{//因为点击登录离开页面时if(YES==_popAsLoginFlag){[self.navigationControllerpopToRootViewControllerAnimated:NO];}}-(void)loginButtonClicked:(id)sender{HSLoginViewController*loginVC=[HSLoginViewControllernew];//[self.navigationControllerpushViewController:loginVCanimated:YES];//原来是从这里（个人设置页）直接push到登录页，由于登录完成后要转到首页，所以这里先把tabbar跳到首页，从首页push到登录页，这样就可以从登录页轻松跳到主页了self.tabBarController.selectedIndex=0;[[self.tabBarController.viewControllersobjectAtIndex:0]pushViewController:loginVCanimated:YES];//标记一下，在这个页面消失时做相应处理_popAsLoginFlag=YES;}
