01 - Pushing a navigation controller is not supported

報錯描述

• 前提 : 自定義storyboard:包含一個navigationController與UIViewnController
• 理想現象 : 用Button跳轉至自定義storyboard
• 報錯reason : Pushing a navigation controller is not supported
• 解決方式 : Storyboard EntryPoint(即進入storyboard的箭頭)直接指向與UIViewnController

跳轉Code:

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"PersonOfDetail" bundle:nil];
    UIViewController *nav = [storyboard instantiateInitialViewController];
    [self.navigationController pushViewController:nav animated:YES];

分析:

將VIewController push到一個NavigationController中,相當於一個入棧操作;
如果push的物件中也有繼承自UINavigationController,則存在NavigationController管理NavigationController物件;
存在衝突,於是就報錯;

修改方法:

被push的物件不要繼承UINavigationController即可
