I have a view controller hierarchy and the top-most controller is displayed as a modal and would like to know how to display the navigation bar when using
\
I had the same problem on ios7. I called it in selector and it worked on both ios7 and ios8.
[self performSelector: @selector(showMainView) withObject: nil afterDelay: 0.0];
- (void) showMainView {
HomeViewController * homeview = [
[HomeViewController alloc] initWithNibName: @
"HomeViewController"
bundle: nil];
UINavigationController * navcont = [
[UINavigationController alloc] initWithRootViewController: homeview];
navcont.navigationBar.tintColor = [UIColor whiteColor];
navcont.navigationBar.barTintColor = App_Theme_Color;
[navcont.navigationBar
setTitleTextAttributes: @ {
NSForegroundColorAttributeName: [UIColor whiteColor]
}];
navcont.modalPresentationStyle = UIModalPresentationFullScreen;
navcont.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self.navigationController presentViewController: navcont animated: YES completion: ^ {
}];
}
One solution
DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil
bundle:[NSBundle mainBundle]];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controller];
navController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
navController.modalPresentationStyle = UIModalPresentationCurrentContext;
[self.navigationController presentViewController:navController
animated:YES
completion:nil];
Can you use:
[self.navigationController pushViewController:controller animated:YES];
Going back (I think):
[self.navigationController popToRootViewControllerAnimated:YES];
I use this code. It's working fine in iOS 8.
MyProfileEditViewController *myprofileEdit=[self.storyboard instantiateViewControllerWithIdentifier:@"myprofileeditSid"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:myprofileEdit];
[self presentViewController:navigationController animated:YES completion:^{}];
It is true that if you present a view controller modally on the iPhone, it will always be presented full screen no matter how you present it on the top view controller of a navigation controller or any other way around. But you can always show the navigation bar with the following workaround way:
Rather than presenting that view controller modally present a navigation controller modally with its root view controller set as the view controller you want:
MyViewController *myViewController = [[MyViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navigationController =
[[UINavigationController alloc] initWithRootViewController:myViewController];
//now present this navigation controller modally
[self presentViewController:navigationController
animated:YES
completion:^{
}];
You should see a navigation bar when your view is presented modally.
If you use NavigationController in Swift 2.x
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let targetViewController = storyboard.instantiateViewControllerWithIdentifier("targetViewControllerID") as? TargetViewController
self.navigationController?.pushViewController(targetViewController!, animated: true)
