IOS--跳转方式两种

带导航栏的Push跳转:

FloatPassViewController *floatpass = [self.storyboard instantiateViewControllerWithIdentifier:@"floatpass"];
    [self.navigationController pushViewController:floatpass animated:YES];

不带导航栏的present跳转:

HomeViewController *home = [self.storyboard instantiateViewControllerWithIdentifier:@"home"];
            //[self.navigationController pushViewController:home animated:YES];
            [self presentViewController:home animated:YES completion:^{
                NSLog(@"登录成功");
            }];
