I have an application with a navigation bar and a tab bar. A user can navigate to a view which displays images in a scroll view. I'd like to have the same behavior as the iPhone photo app: Nav bar at the top, tool bar at the bottom, which will hide or show based upon a tap.
I'm moving my view to the window object in order to achieve full screen mode. This works fine:
myView = [self.view retain];
self.view = nil;
[window addSubview:myView];
But when I want to redisplay the Nav & tool bar, I run into a problem. The bars show fine, but the view is empty, and I can't seem to add any content to the view:
[myView removeFromSuperview];
self.view = myView;
I got a lot of good info from this post
but can't quite get the right combination.
By simply setting the controller's view, you aren't adding it as a subview to anything else, so it will never appear.
Moving views around like this can get a little tricky. I recommend that you not move the view from one to the other, but instead have two UIViews. Add second UIView to the window's subview and set it to hidden=YES initially. When you want to show it, set the image for the UIImageView, and then set the hidden property to NO.
what's wrong with just using setNavigationBarHidden: animated: and setToolbarHidden:animated:?

I haven't been able to find anything on this and feel it likely isn't possible in a simple manner.
Can I have a view, such a loading bar for example which constantly sits over every other view controller until I choose to dismiss it but at the same time any underlying view can still be interacted with? Sort of acting like a system view. Be persistent when presenting new view controllers and all.
Thanks.
Add it as a subview of your window. Like this:
UIView *myView = ...
[self.window addSubview:myView];
Rather than adding it to the window, as #JackyBoy suggests, add it to the window's rootViewController's view. That will rotate along with the device. If you just add it to the window, you may have problems with rotation.
UIView *myView = ...
[UIApplication sharedApplication].keyWindow.rootViewController.view addSubview:myView];
I am trying to make some kind of popup view when a button i pressed on the iPhone. And it would be nice if I could manage that popup view with a ViewController. I have found out that the UIPopoverController could have been the solution, but it seems that it only works on the iPad...
But anyway, are there any similar solutions for the iPhone?
I am using storyboard
Check out these repos on Github:
https://github.com/werner77/WEPopover
https://github.com/50pixels/FPPopover
Create a separate view controller and resize its xib file and make it look like a popup.
Then ADD this view controller as a subview, and also add it as childController too.
[self addChildViewController:self.popOverViewController];
[self.view addSubview:self.popOverViewController.view];
Now Make it hidden initially.
self.popOverViewController.view.hidden = YES;
If a user taps on Button then using fade in & Fade out animation you can hide/unhide it.
I can tell you how to fade in and fade out if you want to know it further, I hope you can do it easily.
In interface builder make a UIView size of the screen and then make another in that Uiview with the style, size and the such for your pop over. Make its class, hook everything together.
CustomPopUpView *view = [[CustomPopUpView alloc] initWithFrame.....]
Add this all to your UIViewController with
[self.view addsubview:view]
Then attach a tapGestureRecognizer to the back view that animates the whole view off screen when tapped. So now if they click off your pop over view it close it will animates it off screen.
Hope this makes sense.

I've been trying to add a UIView (with a UIImageView) as an initial screen when the user launches my application for the first time. However, even after I hide the tab bar, or move its frame out of the screen, the UIView still crops itself as if the tab bar was still there.
Both of these code blocks produced the same result:
[appDelegate.tabBarController.tabBar setFrame:CGRectMake(0,1000,0,0)];
[self setView:InitialView];
and
[appDelegate.tabBarController.tabBar setHidden:YES];
[self setView:InitialView];
Here's a screenshot of the incident in action:
Does anyone know how to fix this problem? I've been puzzling away at this for the past few hours, and I can't seem to do anything about it.
Presumably you have your view's view controller inside this tab bar controller. As a result, the view controller's view is getting sized appropriately to fit inside the tab bar controller's view. Why don't you just get the frame of the tab bar and adjust the height of your view by the view's current height + the tab bar's height?
As a side note, I am assuming InitialView is a UIView (or subclass) instance. It is standard Object-Oriented Programming convention to name instances of classes with a lower case letter, and then to proceed in camel case, as in initialView. Just an FYI.
Try this reference your App Delegate which should take in account the UITabBarController. Just the UIImageView as a subview, and when you are done just remove it. You'll obviously have to import your AppDelegate.
AppDelegate *appDelegate = (AppDelegate*)[[UIApplication sharedApplication]delegate];
[imageView addSubview:appDelegate.window];
I have a Tabbar application with a navigation controller (classic).
At some point when a url is selected a WebView controller is displayed with the appropriate url address.
I want to be able to use the tabbar area placing the webview over it. I tried
[self.tabBarController.tabBar setHidden:TRUE];
but this just makes the tabbar white.
How can i do this?

You can use theView.hidesBottomBarWhenPushed. Then when you push the view onto the navigation stack, the bottom bar (tab bar) will be hidden.
If you want to hide the tab bar from within the view itself, afaik the only way is to hide it by either using .hidden = YES or changing the frame. Then you need to change the frame (more specifically the height) of the view to fill the empty space.
Changing the height will not do anything because the tab bar is still sitting on top of the UIView which is holding the UIWebView. You need to do something to this extent:
[[[[UIApplication sharedApplication] delegate] window] addSubview:webView];
The only issue I am having now is that the webView is being pulled behind the UIView that is holding it. : (
I guess you can put an IBOutlet hook in there and perform a sendToBack on the UIView but I am going to keep searching for a better solution.
I have an application with a tab bar and a navigation bar. I push a view controller that is used to show photos, one at a time. It initially shows the bars and forward/back controls; after a delay, these hide, using setNavigationBarHidden:animated: and a custom transform (CGAffineTransformMakeTranslation) on the tab bar. This works, but the view controllers view , which shows the photo, leaps up and down. The same is true if I leave the tab bar out of the equation.
How can I prevent the UINavigationBar from moving my view around? I would like the photo to stay fixed in the screen, with the nav bar dropping down over the top segment of it.
Had this issue and fixed it with a class that inherited from UINavigationController
-(void)viewWillAppear:(BOOL)animated
{
self.navigationBar.translucent = YES;
}
Worked great for me, didn't had to set style to UIBarStyleBlackTranslucent. So it did kept my colors.
[[navigationController navigationBar] setBarStyle:UIBarStyleBlackTranslucent];
[[navigationController navigationBar] setAutoresizesSubviews:NO];
this seemed to do the trick for me!
I know this is an old question, but I accomplished that by disabling 'Autoresize Subviews' in Interface Builder
I haven't been able to find a proper way to handle this except to set the navigationBar style to translucent as in:
theNavigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;
Other than creating another navigation bar and adding buttons to them, that's the best (and it seems to be what Apple does as well in it's Photo app)
