1,present 一个UIViewController
SecondViewController *secondVC = [[SecondViewController alloc]init]; secondVC.modalPresentationStyle = UIModalPresentationOverCurrentContext; [self.navigationController presentViewController:secondVC animated:YES completion:^{ }];
2,present 一个UINavigationController,注意修改的是UINavigationController的modalPresentationStyle。
SecondViewController *secondVC = [[SecondViewController alloc]init]; UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:secondVC]; nav.modalPresentationStyle = UIModalPresentationOverCurrentContext; [self.navigationController presentViewController:nav animated:YES completion:^{ }];
