1.当有业务逻辑,需要来回跳转的时候,使用push pop(详见彩票项目的设置按钮的跳转)
HMSettingController *vc = [HMSettingController new];
[self.navigationController pushViewController:vc animated:YES];
------------------------------------------------------------------------------------------------------------------------
2.当页面只需要跳转一次的时候 (在appDelegate中实现,用到了通知)(详见网络登录页面)
//获取控制器,登录页面的控制器
UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Login" bundle:nil];
//跟控制器指向登录页面的控制器
self.window.rootViewController = sb.instantiateInitialViewController;
------------------------------------------------------------------------------------------------------------------------
3.modal
SubViewController *subView = [[SubViewController alloc] initWithNibName:@"SubViewController" bundle:[NSBundle mainBundle]];
//跳转到subview控制器
[self presentViewController:subView animated:YES completion:nil];
//返回
[self dismissViewControllerAnimated:YES completion:nil];
