iphone - PushViewController 导致黑屏

Question

SettingsViewController *viewController = [[SettingsViewController alloc] init];
    [[self navigationController] pushViewController:viewController animated:YES];

在 NavigationController 中使用此代码时，显示的场景只是黑屏。在 Storyboard 中显示内容，但不显示在手机上。

Answer 1

试试这个:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle: nil];
SettingsViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"setting"];
[self.navigationController pushViewController:viewController animated:YES];

设置settingviewcontroller的标识符为“setting”
