01 - Pushing a navigation controller is not supported
报错描述
- 前提 : 自定义storyboard:包含一个navigationController与UIViewnController
- 理想现象 : 用Button跳转至自定义storyboard
- 报错reason : Pushing a navigation controller is not supported
- 解决方式 : Storyboard EntryPoint(即进入storyboard的箭头)直接指向与UIViewnController
跳转Code:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"PersonOfDetail" bundle:nil];
UIViewController *nav = [storyboard instantiateInitialViewController];
[self.navigationController pushViewController:nav animated:YES];分析:
将VIewController push到一个NavigationController中,相当于一个入栈操作;
如果push的对象中也有继承自UINavigationController,则存在NavigationController管理NavigationController对象;
存在冲突,于是就报错;
修改方法:
被push的对象不要继承UINavigationController即可
