一、纯代码跳转

UIViewController *Vc = [[UIViewController alloc] init];

[self.navigationController pushViewController:Vc animated:YES];

二、根据segue跳转

[self performSegueWithIdentifier:@"toFriendList" sender:nil];

三、根据view的id跳转

UIViewController *Vc = [self.storyboard instantiateViewControllerWithIdentifier:@"toNext"];

[self.navigationController pushViewController:Vc animated:YES];

注意：第一种是创建出新的页面跳转的

//模态推出页面

//不在导航控制器

UIViewController *Vc = [[UIViewController alloc] init];

[self presentViewController:Vc animated:YES completion:^{

NSLog(@"第二页已经被推出");

}];

//模态页面时的动画

second.modalTransitionStyle = UIModalTransitionStyleCoverVertical;

//退出模态

[self dismissViewControllerAnimated:YEScompletion:^{

NSLog(@"已经退出模态");

}];
