[ios]多个storyboard跳转

1、单个storyboard跳转

UIStoryboard *board = self.storyboard;
                HomeController *homevc = [board instantiateViewControllerWithIdentifier:@"homevc"];
                [self.navigationController pushViewController: homevc animated:YES];

2.多个：

UIStoryboard *board = [UIStoryboard storyboardWithName:@"Login" bundle:nil];
LoginController *loginvc = [board instantiateViewControllerWithIdentifier:@"loginvc"];
[self.navigationController pushViewController: loginvc animated:YES];

PS：在有多个storyboard的情况下，都要替换成这种声明方式

*不同跳转方式：

//Modal方式
 
 
 
[self presentModalViewController:my_device_vc animated:YES];
  //使用了navitgation 
 
[self.navigationController pushViewController: loginvc animated:YES];
   
 
 //回退
 
 
[self.navigationController popViewController animated:YES];

swift:

let bookDateVC = UIStoryboard(name: "Book-date", bundle: nil).instantiateViewController(withIdentifier: "book-date")
bookDateVC.title = "预约日期及时间"
self.navigationController?.pushViewController(bookDateVC, animated: true)
