Status Bar blinks when awake from background state - ios

In some of app's view controllers status bar is hidden. But when user opens the app from a background, status bar becomes visible for a second, and then hides.
I tried:
to put [[UIApplication sharedApplication] setStatusBarHidden:YES]
into applicationWillEnterForeground: method. However, status bar becomes visible before this method is called.
check status bar's visibility when applicationWillResignActive:
self.isStatusBarHidden = [UIApplication sharedApplication].statusBarHidden ? YES : NO;, but it returns <nil>. (Then I wanted to hide status bar and show it when applicationWillEnterForeground - this leads to a completely opposite situation)
How to solve this problem?
P.S. View controller-based status bar appearance in my .plist file is equal to NO and Status bar is initially hidden is equal to NO too.

Are you keeping your settings like this?
You need to check status bar style Hide during application launch.

Status bar icons disappear and then slowly reappear

I have found that the status bar will disappear when swapping the window's root view controller.
I have View controller-based status bar appearance set to NO
I am swapping between two different view controllers via
[UIApplication sharedApplication].delegate.window.rootViewController = rootVC;
Immediately upon displaying the new rootVC the status bar icons all disappear and slowly (10 seconds) begin to reappear. During this time the UI is responsive otherwise. I am not otherwise setting the visibility of the status bar via any method that I know to set the status bar visibility. Neither the old or the new rootVC are displayed as a modal.
So I found that if I changed the View controller-based status bar appearance plist property to YES and called [self setNeedsStatusBarAppearanceUpdate] from the new rootVC the statusbar icons didn't change.

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.

Removing Status Bar In IOS 8 When Using A UINavigationController

I am trying to remove the status bar from my app when moving between views in a UINavigationController.
I have a UINavigationController that has the status bar removed. I then select an image using UIImagePickerController, I think it is this that is resetting the status bar appearance.
After selecting the UIImage I push another view and present the image, the problem is that the status bar has reappeared.
I have tried a number of approaches including calling prefersstatusbarhidden on both views without without any luck.
Any ideas how to remove the status bar?
Thanks
If using iOS8, add
-(BOOL)prefersStatusBarHidden{
return YES;
}
to your view controller. You will need to add this to each view controller as required.
You could alternatively specify a value for the key View controller-based status bar appearance in info.plist to specify your status bar preferences app-wide.
Try hiding the status bar manually using this
[[UIApplication sharedApplication] setStatusBarHidden:YES];

iOS 7 Cannot See Status bar (Signal , Time, Battery) When I Fixed Navigation Bar overlap TableView

I fix problem iOS 7, Navigation Bar is Overlap Table View.
I use this Code
//for help navigation bar overlap
if ([self respondsToSelector:#selector(edgesForExtendedLayout)])
self.edgesForExtendedLayout = UIRectEdgeNone;
I can fix this problem but navigation bar overlap status bar not show signal battery time same this picture:
Actually your status bar is visible but your status bar text color is black so you can't see properly. if you just see from upside of your mac screen you can see this.
So follow the smita's answer is current but after change in plist you need to change it statusBar style with UIStatusBarStyleLightContent that change to your statusbar text color black to white.
In to your image that already display that clock time signal or battery status. with black color and your navigation bar tint color already black so that both are match. that's why you can not see that.
But only setting this line of code not enough.
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
You need to change in to plist like
add one row with UIViewControllerBasedStatusBarAppearance set to NO. like bellow
now run you project that your navigation and statusbar look like:-
In your AppDelegate's didFinishLaunchingWithOption method add this line of code -
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
May this will help you.
In IOS7, if you want status bar depending on the view controller you can set the "View controller-based status bar appearance" in info-plist to "YES".
Override following method in all your controller to decide whether your that view need status bar or not.
-(BOOL)prefersStatusBarHidden

Changing status bar color on button click - iOS

If I were wanting to change the status bar's color from white to black when I click a button, how would I do that? I'm not using this for a app or any practical purpose but I just want to see how it would look.
Thanks :)
If you want to change your status bar appearance from UIStatusBarStyleDefault to UIStatusBarStyleLightContent
on button click call below method ->
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:YES];
For that to work
you have to set View controller-based status bar appearance as NO in app plist keys.
