Can see Status Bar space but not information in iOS Swift - ios

I add Navigation Controller(2nd View) and add one UIViewController(3rd View) as root view controller.
And then I connect segue to Navigation Controller(2nd View) from anther UIViewController(1st View).
So I can see navigation Bar with Status bar space when the view is presented.
But the information like Carriers, batteries, time information are not shown in Status Bar.
(I changed navigation Color to pink for showing you the problem.
The blue part is title view for navigation bar.)
So I tried 2 solutions.
First, I thought StatusBar Color problem. But it was not.
UIApplication.shared.statusBarStyle = .default
Second, I tried following code for showing. It was not also.
override var prefersStatusBarHidden: Bool {
return false
}
and
UIApplication.shared.setStatusBarHidden(false, with: UIStatusBarAnimation.none)
I need to solve this not-showing problem with status Bar.
I can see status Bar space but not information.

There are lots of ways to toggle the color and visibility of the status bar in iOS.

How to change Status Bar text color in iOS 7
In short, if you want to toggle it between every screens, follow these steps:
In your info.plist, add this new key:
View controller-based status bar appearance and value should be NO.
In your viewWillAppear, toggle the status bar with the code you have posted:
UIApplication.shared.statusBarStyle = .lightContent - white
or
UIApplication.shared.statusBarStyle = .default - black
Edit:
Initial ViewController --> Present Modally --> NavigationController + ViewController.
This is how you set up your screens, right?. If so,
You can setup the status bar in your NavigationController properties in your Interface Builder.
And toggle the visibility and/or color of your status bar in side the viewWillAppear of your 3rd ViewController.

I suggest you check out Debug View Hierarchy.
Based on my experiences in previous projects, if I can't come up with code-based solutions on UI-related problems the simplest debugging technique that I can do is check the view hierarchy during run time.
See if the Navigation Controller View blocks the Main View which can possibly hide the status bar and if yes, work your way on solving it.
I hope it helps.

How can I ensure iOS 13 modal view controllers present the right status bar colour?

With the new iOS 13 view controller changes, view controllers are being presented that don't cover the whole screen. They instead leave a black space at the top. However, the system status bar is not changing colour automatically. When I present a modal view controller, the status bar is staying with now-invisible black text (and a green battery which looks super weird in the middle of nowhere).
How do I make the bar behave in the same way as within Apple's apps, where the bar animates to different colour when a modal popup appears?
I've tried setting modalPresentationCapturesStatusBarAppearance to true on my modal controllers, to no luck.
The bar in my presenting view controller is a UINavigationBar, and is not part of a navigation controller. The presenting VC is its delegate, and I've overridden position(for bar: UIBarPositioning) to return .topAttached.
I've tried presenting the modal with .modalPresentationStyle = .formSheet and without setting .modalPresentationStyle at all. Neither worked.
Broken:
The presenting VC:
Expected Behaviour:
Two things:
The modal view controllers need to have VC.modalPresentationCapturesStatusBarAppearance = false. This is the default but if, like me, you set it to something else, make sure it's false!
You need to ensure that View controller-based status bar appearance in your info.plist is set to YES. I'd messed around with it in an attempt to make my status bar the right colour but having it set to NO was a problem.

New UINavigationBar appearance in detail pane of UISplitViewController in iOS 13

Under iOS 13, if you setup a scrollable root view controller (such as a UITableViewController) in a navigation controller and then put that navigation controller in the detail pane of a UISplitViewController, then the nav bar's background isn't visible when the scrollable content is at the top.
You can see this by creating a new iOS project based on the Master/Detail template. Then modify the storyboard to use a UITableViewController inside the detail pane's nav controller. Put the device/simulator in Light Appearance mode (it shows the problem better than Dark mode). Run the app and notice the nav bar area is the same color as the table view background. Now scroll the table view up and the nav bar color changes to the standard light gray. Let the table view return to the top and the nav bar color disappears again.
I've only seen this in the detail pane of a split view controller.
How do you turn off this "feature" so that the nav bar looks normal just like every other nav bar used anywhere else other than the detail pane of a split view controller?
There are no relevant API changes for UISplitViewController or UISplitViewControllerDelegate. There's nothing in UINavigationController either.
After some digging I found one workaround but I'd love to find a way to avoid having to do this.
The UINavigationBar class now has some new properties for setting its appearance. Oddly, none of these are mentioned under the "Customizing the Appearance of a Navigation Bar" in the documentation for UINavigationBar.
There are three new properties in iOS 13:
standardAppearance
compactAppearance
scrollEdgeAppearance
All three are of type UINavigationBarAppearance.
Only the first one is set by default.
Even though scrollEdgeAppearance is nil, the detail pane of a split controller acts as if this has been set with the backgroundColor set to the clear color.
So the workaround is to add the following line to the viewDidLoad method of the navigation controller's root view controller:
navigationController?.navigationBar.scrollEdgeAppearance = navigationController?.navigationBar.standardAppearance
Why is this needed only in this one case? Is there a more correct solution other than adding this code?
I noticed that none of Apple's apps (Mail, Notes, and Files at least) seem to use this "feature".
The workaround you found is the 'official' way to disable this behavior, as explained in a thread on Twitter by David Duncan who is on the iOS System Experience team at Apple.
to control what happens when the UINavigationBar is completely
unfurled, you want to set the scrollEdgeAppearance. By setting
standardAppearance and scrollEdgeAppearance to the same values, you
will get a bar that doesn't change.
An Apple app that does not disable this behavior is the Settings app.

Status Bar Icons Turn Black when Search Bar is active

Okay, so...
I have set the NavigationBar Style to Black so that the Status Bar Icons become White.
(See Pic 1 Below)
The Problem begins with the Search Bar. When it's active and you can type it turns the NavigationBar Style back to Default which makes the Status Bar Icons Black again. Though once you are done with it and it goes back to being inactive, the NavigationBar Style goes back to Black, where it should be all the time.
(See Pic 2 Below)
I haven't found a way yet to make the Status Bar Icons remain White at all times.
Help is much appreciated.
It sounds like you have view controller based status bar appearance setup.
If you want the status bar to be white all the time, then you can set the UIViewControllerBasedStatusBarAppearance info.plist key to NO and then set UIStatusBarStyle key to UIStatusBarStyleLightContent.
If you do want to keep view controller based status bar appearance, then you will need to subclass UISearchController and override the status bar style as you are technically presenting a different view controller for search hence the change in status bar style...
class SearchController: UISearchController {
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return .LightContent
}
}
(note that i assume you are using UISearchController as your question doesn't mention your approach)

setStatusBarHidden deprecated, but only thing that works

I've tried all the solutions I can find including those in: setStatusBarHidden is deprecated in iOS 9.0 but none of them work with my application.
It is a simple, single view application. There is a Navigation bar with a single button on it which the status bar should show on top of.
In my .plist:
Status bar is initially hidden: NO
Status bar style: UIStatusBarStyleLightContent
View Controller based status bar appearance: NO
Changing any of these doesn't seem to make any difference at all. I have the status bar style "Hide during application launch" option checked as I don't want it to appear on the splash screen.
I have:
- (BOOL)prefersStatusBarHidden
{
return NO;
}
-(UIStatusBarStyle)preferredStatusBarStyle
{
NSLog(#"style");
return UIStatusBarStyleLightContent;
}
and setNeedsStatusBarAppearanceUpdate which are definitely all called when the view loads in my ViewController.
The view is established in a .storyboard, but many of the fields are manipulated in the ViewController.m as well. The value assigned to the status bar in the simulated metrics doesn't seem to have any effect either.
I need my status bar to be hidden during the launch screen and visible on the viewController. Please help me find a solution that doesn't use the deprecated setStatusbarHidden!
EDIT:
I still haven't solved this, and I surely can't be the only one with this problem! It happens in both apps that I have written.
I've just been trying to solve the same problem, I don't know why the setStatusBarHidden and setStatusBarStyle have been deprecated as the new methods are not at all intuitive.
To hide the status bar on launch I have these settings in my plist:
View controller-based status bar appearance: YES
Status bar is initially hidden: YES
Then to show the status bar after launch I have in my view controller:
- (BOOL)prefersStatusBarHidden {
return NO;
}
-(UIStatusBarStyle)preferredStatusBarStyle {
return UIStatusBarStyleLightContent;
}
This still didn't work until I found this answer https://stackoverflow.com/a/19365160/488611. So in viewDidLoad I also set the navigation bar style:
self.navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;
Which makes absolutely no sense, but works.
you can use
application.statusBarHidden=YES;
in AppDelegate.m
didFinishLaunchingWithOptions
In my mind, you should change the value of UIViewControllerBasedStatusBarAppearance.
Set the value file .plist of project a is
UIViewControllerBasedStatusBarAppearance = NO
and check in file AppDelegate and set the code
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
Hope my solution can be solved your problem.
OK, I totally misunderstood your question. Here's the correct answer.
Add the below value to you 'info.plist'.
Status bar is initially hidden : YES
View Controller based status bar appearance : YES
On UIViewControllers which you want to show status bar
- (BOOL)prefersStatusBarHidden {
return NO;
}
That's all.
I am not an expert on this, but I played with these settings for some time and came to the following conclusions.
General/Deployment Info:
Status Bar Style: Default (black), Light
Hide status bar (checkbox)
Both change the status bar on the launch screen only.
Note that if you take a screen shot to create this image and the screen shot included a status bar, it will appear that the device is setting the status bar even if you have checked the Hide status bar checkbox! I was tricked by this for a while before I finally thought to look at the launch image itself, and there was a status bar in the photo, so setting Hide never seemed to work even though it really was working. I removed the status bar from the images themselves using Photoshop, and the launch status bars functioned as expected after that.
Info/Custom iOS Target Properties (these change the values in the PLIST, so you could change them in either place):
Status Bar Is Initially Hidden: Yes/No
Status Bar Style: Gray (default), Transparent Black, Opaque Black
View Controller based status bar appearance : Yes/No
If you set Status Bar Is Initially Hidden to No, then you will have the status bar on your View Controller like you wanted. If you want to hide the status bar on your View Controller, you have to set Status Bar Is Initially Hidden to Yes AND set View Controller based status bar appearance to No.
Attributes Inspector for the View Controller/Simulated Metrics
Status Bar: None, Inferred, Default, Light, Black (deprecated)
This seems to have no effect on anything except the appearance of the view controllers in the StoryBoard but NOT in the simulator.
Summary: To answer your question, under General Deployment Info, check the checkbox that says Hide Status Bar. This will hide the status bar on the launch screen. Make certain that your image for the launch screen does NOT have a picture of a status bar in it. None of the settings in the StoryBoard or in the Target seems to turn off the view controller's status bar, so it seems that it will stay on like you wanted. However, I did not test any of the programmatic settings; I think that you should not do any of those, and it will work the way you want.

Getting correct color of status bar in ios

Okay I am having some trouble coloring my status bar. I have a pretty simple app that moves between two views. I tried coloring the status bars of the navigation controller with this code
[[UINavigationBar appearance] setBarTintColor:UIColorFromRGB(0x067AB5)];
But it did not work until I removed the "navigation controller's" status bars and dragged status bars into the storyboard. Then I wanted the status bar to match the color so I deleted the navigation controller and it worked! I think the navigation controller status bar was not allowing the status bar to be colored correctly. However, without a navigation controller I cannot add a "push" segue. This is what it looks like with the navigation controller
And here it is without
I don't know what the solution is because I need the nav controller for this to work I think. For some reason there is no "show" option. Let me know what I should do. Thank you!
Per, http://www.appcoda.com/customize-navigation-status-bar-ios-7/ (although we are now working with iOS 8, the color of the navigation bar and status bar are the same by default. It sounds like you really do want their colors to be the same (is this what you mean by "correct color"?).
To do this in storyboard, I would add your first UIViewController to the storyboard. Click this UIViewController, go up to the menu and click Editor -> Embed in -> Navigation Controller. You will see now that the Navigation Controller is the initial scene and your UIViewController is the root view controller. Then add a second UIViewController. Ctrl drag from the first UIViewController to the second view controller and create a show (push) segue.
Now to change the color of the UINavigationController. Click of the UINavigationController (the first scene). In the outline on the left, click on the Navigation Bar. In the inspector on the right, you should see a Navigation Bar section with Style and Tint underneath. For a solid look, you can select Black Opaque and change the tint color to whatever you like. Note that your selection will roll through to your UIViewControllers. When you build the app, the status bar should now match the color of the navigation bar.
