When I'm going back from my Modal View Controller to my Main View Controller (I have a horizontal animation) my Main Controllers navbar places itself a bit too high for a quick second and then jumps back to its right position. Does somebody know why? Ive been googling it but with no success.
App Delegate:
[navigationController.navigationBar setBarTintColor: [UIColor whiteColor]];
[navigationController.navigationBar setTranslucent: NO];
When i push button to open my Info View:
UIViewController *infoViewController;
infoViewController = [[InfoViewController alloc] initWithNibName:#"InfoViewController" bundle: nil];
infoViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController: infoViewController animated: YES completion:nil];
I'm not using Auto Layout on any xib-files. My Main View Controller xib-file is empty with Status Bar: Default. My Info View Controller xib-file has some stuff in it.
Code for closing my Modal View Controller:
-(IBAction)onBackBtnClick:(id)sender
{
[self dismissModalViewControllerAnimated: YES];
}
All what you have to do is to add the following code in the ViewWillAppear of the "InfoViewController" viewController class
-(void) viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
[self.navigationController.navigationBar setTranslucent:NO];
[self.navigationController.navigationBar.layer removeAllAnimations];
}
Hope it worked with you :)
The problem seems to be
infoViewController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
If you change this to
infoViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
then it will no longer jump. This worked for me. Good luck!
In my .plist file, I have "View controller-based status bar appearance" set to NO. But after UIImagePickerController, my app behaves as if the option is set to YES.
In my app, I present a VC that presents a UIImagePickerController.
The problem happens like this:
After photo picker is presented, when a photo library is picked, the color of the status bar text changes.
Then once, UIImagePickerController is dismissed, status bar spacing
changes for the rest of my app and all the navigation bar for other controllers displays under the status bar.
Is there a way to solve this without managing status bar in my view controllers?
None of the solutions above worked for me, but by combining Rich86man's and iOS_DEV_09's answers I've got a consistently working solution:
UIImagePickerController* imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
and
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarHidden:YES];
}
Regarding this awesome solution. For 2014 / iOS8 I found in some cases you need to ALSO include prefersStatusBarHidden and, possibly, childViewControllerForStatusBarHidden So...
-(void)navigationController:(UINavigationController *)navigationController
willShowViewController:(UIViewController *)viewController
animated:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarHidden:YES];
}
-(BOOL)prefersStatusBarHidden // iOS8 definitely needs this one. checked.
{
return YES;
}
-(UIViewController *)childViewControllerForStatusBarHidden
{
return nil;
}
-(void)showCamera
{
self.cameraController = [[UIImagePickerController alloc] init];
self.cameraController.delegate = (id)self; // dpjanes solution!
etc...
I faced this same issue today. Here is my solution.
In the view controller who calls the image picker, set yourself as the delegate of the image Picker. (You're probably already doing this)
UIImagePickerController* imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
Since UIImagePickerController is a type of Navigation controller, you're also setting yourself as the UINavigationController delegate. Then :
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}
Replace UIStatusBarStyleLightContent with whatever style you are looking for.
The accepted answer will work if you have the 'View controller-based status bar appearance' set to NO in your .plist file. If indeed you need to control the status bar in some other view controllers and have this option set to YES, the other way to make UIImagePickerController to behave correctly is by subclassing it
// .h
#interface MYImagePickerController : UIImagePickerController
#end
// .m
#implementation MYImagePickerController
- (UIStatusBarStyle)preferredStatusBarStyle
{
return UIStatusBarStyleLightContent; // change this to match your style
}
#end
i faced the same problem.
here is my solution.
put this in the viewWillAppear of the view controller from which you are opening the image pickerview
-(void) viewWillAppear:(BOOL)animated{
[super viewWillAppear:YES];
[[UIApplication sharedApplication] setStatusBarHidden:YES];
}
Can you try this. I think needsStatusBarApperanceUpdate will work.
1 -Set UIViewControllerBasedStatusBarAppearance to NO.
2- Call [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
3- [self setNeedsStatusBarAppearanceUpdate];
I found this to offer proper handling, there's two parts.
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];
...
the UIImagePickerController itself presents view controllers, so this delegate works for all presenters on the stack.
the viewWillAppear ensures this view controller itself is always reset whenever a presenting view controller dismisses above it.
I had the same problem.
Add in info plist: "View controller-based status bar appearance" with value "NO"
Example here https://stackoverflow.com/a/19211669
This solution works for me.
This is probably a bug. I solved the problem by setting "View controller-based status bar appearance" set to YES and in every view controller pasting in the following code:
- (BOOL)prefersStatusBarHidden
{
return YES;
}
Then my app behaves as expected.
For hiding the status bar in UIImagePicker :
-
(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}
and when UIImagePicker is dismissed to hide the status bar in View controller use the following code :
-(void) viewWillAppear:(BOOL)animated{
[super viewWillAppear:YES];
[[UIApplication sharedApplication] setStatusBarHidden:YES];
}
try this ....
this will work in both cases i.e whether you use presentModalViewController and pushViewController
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
delegate methods
-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[picker dismissViewControllerAnimated:YES completion:^{}];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[picker dismissViewControllerAnimated:YES completion:nil];
}
All the above didn't work for me. I solved the issue by changing the presentation style to:
imagePickerController.modalPresentationStyle = UIModalPresentationFullScreen;
None of the above solutions worked for me.
I present UIImagePickerController as modal view controller. After dismissing UIImagePickerController the status bar state was:
[UIApplication sharedApplication].statusBarOrientation = 0 (UIDeviceOrientationUnknown)
[UIApplication sharedApplication].statusBarFrame = { 0, 0, 0, 0}
The solution that fixed the problem for me was restoring statusBarOrientation after dismissing UIImagePickerController:
UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
[self.viewController presentViewController:cameraUI animated:true completion:^(void){ }];
...
[self.viewController dismissViewControllerAnimated:animated completion:^(void){
[UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationPortrait;
}];
This code helped me to customize status bar style.
EDIT: this solution works if "View controller-based status bar appearance" == YES
#implementation UIImagePickerController (IOS7_StatusBarStyle)
-(UIViewController*)childViewControllerForStatusBarStyle
{
return nil;
}
-(UIStatusBarStyle)preferredStatusBarStyle
{
return UIStatusBarStyleLightContent;
}
#end
All the answers above is ok and can help.
I had the same problem having to manage the application runned under different iOS versions.
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
if(IS_IOS8_AND_UP) {
imagePickerController.modalPresentationStyle = UIModalPresentationFullScreen;
} else {
imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
}
imagePickerController.delegate = self;
[self presentViewController:imagePickerController animated:YES completion:nil];
Then, in delegate:
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
/* Cancel button color */
_imagePicker.navigationBar.tintColor = <custom_color>
/* Status bar color */
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
}
Yet another solution which may work in some of the situations.
let imagePicker = UIImagePickerController()
imagePicker.sourceType = .PhotoLibrary
imagePicker.navigationBar.barStyle = .Black
Have you tried calling [self setNeedsStatusBarAppearanceUpdate] when your presenting view controller reappears?
I try to hide the status bar in UIImagePickerController in iOS7, but I still don't know how to do this. I use
- (void)viewWillAppear:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarHidden:YES
withAnimation:UIStatusBarAnimationNone];
}
in the ViewController that call the UIImagePickerController, and set "View controller-based status bar appearance = NO" in the plist file. Hope this can help.
try this :
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
and in the protocol implement, use this:
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarHidden:YES];
}
This solved it for me...:
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[picker dismissViewControllerAnimated:YES completion:nil];
}
Nothing here specifically fixed the problem in that I was having (and perhaps that the OP was having too), so I thought I would share my answer. Instead of hiding the status bar which I think is a buggy solution (I noticed that it would sometimes leave my app in a state where the status bar was hidden when it shouldn't be). I instead opted to try and play nice with the UIStatusBarStyles.
When the UIImagePickerController has its view presented I set the status bar style to default since the default background color is a light grey.
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES];
}
Then, when the image picker is dismissed, I set it back to the UIStatusBarStyleLightContent.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
//work
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:YES];
[self dismissViewControllerAnimated:YES completion:NULL];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
//work
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:YES];
[self dismissViewControllerAnimated:YES completion:NULL];
}
In this case,We are using 2 steps
In first step:
Add in info.plist: "View controller-based status bar appearance" with value "NO"
In Second step: Use/call this code with delegate of UIImagePickerController
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
if([navigationController isKindOfClass:[UIImagePickerController class]])
[[UIApplication sharedApplication] setStatusBarHidden:YES];
}
In case of IOS-7 add One more Function
- (BOOL)prefersStatusBarHidden
{
return YES;
}
As of iOS 8.1, it seems like they've finally fixed this bug! I was able to remove all of the workarounds I employed from my code.
Using the default iOS 8 behaviour I was having problems with the status bar appearing when I wanted it hidden.
The solution I found was that, directly after calling presentPopover from my view controller I did:
[self performSelector:#selector(setNeedsStatusBarAppearanceUpdate) withObject:nil afterDelay:0.01];
I also had to add this to my main view controller:
- (UIViewController *)childViewControllerForStatusBarHidden
{
return nil;
}
So I had this problem and I was able to solve it by simply implementing a single delegate function. The background of my status bar is black, and so UIStatusBarStyle for my application is .LightContent. When I presented the UIImagePickerController to select a photo from the device storage, the status bar was fine. However, upon clicking into a directory such as "Camera Roll" or "Favorites," effectively pushing onto the navigation stack, the status bar disappeared. Upon selecting a photo, there was no status bar at all; upon dismissing another modal view controller, only the battery was present, indicating the rest of the status bar may be black as well.
I tried some of the other solutions such as extending UIImagePickerController, but in Swift, you cannot override using extensions. I then tried to subclass UIImagePickerController and tried to hide its status bar on viewWillAppear() and unhiding the status bar on viewWillDisappear. I was able to see the status bar hide with a .Slide animation, but since the status bar was invisible upon selecting a directory, I was not able to see the status bar unhide. Again, the green battery came back with the rest of the status bar invisible upon dismissing a modal view controller. I also tried overriding prefersStatusBarHidden(), but that function was never called, so I tried calling setNeedsStatusBarAppearanceUpdate() to ensure that prefersStatusBarHidden() is called by the system, but it still is not called. Also, there is the suggestion to set the status bar to be hidden on the delegate method navigationController willShowViewController. Once again, all this does is hide the status bar, which does not solve the problem. As it turns out, it seems that the status bar style is changed upon pushing onto the navigation stack of the UIImagePickerController. To solve the problem entirely, I did not have to write extensions or subclass UIImagePickerController. All you need to do is set the delegate and set the status bar style to remain the same. This addition made it as if the problem never existed.
let pickerController = UIImagePickerController()
pickerController.delegate = self
func navigationController(navigationController: UINavigationController, willShowViewController viewController: UIViewController, animated: Bool) {
UIApplication.sharedApplication().setStatusBarStyle(.LightContent, animated: false)
}
I actually found a better way to set the status bar background color in Image Picker. Basically you need to set the backgroundImage from the navigationBar to nil, because is default in Image Picker has a backgroundImage as a white Image.
I am having two viewControllers , I am navigating from the FirstView to SecondView , by
pushing the SecondView to the navigation controller. Since I don't want the navigation bar
to be shown in the SecondView , I do the following
self.navigationController.navigationBar.hidden=YES;
Then I move back from the, secondView to the FirstView as follows
[self.navigationController popViewControllerAnimated:YES];
But now the navigation Bar is not shown in the FirstView as well since I am hiding it in the
SecondView. I am trying to the following in the FirstView
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:YES];
self.navigationController.navigationBar.hidden=NO;
}
Try this instead:
- (void) viewWillAppear:(BOOL)animated
{
[self.navigationController setNavigationBarHidden:NO animated:NO];
[super viewWillAppear:animated];
}
You set initWithNib or viewDidLoad method and run it
-(void)viewDidLoad
{
self.navigationController.navigationBar.hidden=NO;
}
Trying show the navigationBar before you pop the second view controller, like this:
self.navigationController.navigationBar.hidden=NO;
[self.navigationController popViewControllerAnimated:YES];
try it in the following method:
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:YES];
self.navigationController.navigationBar.hidden=NO;
}
but to me it should work in viewWillAppear.
Place the below code in the second view
-(void)viewWillDisappear:(BOOL)animated{
self.navigationController.navigationBarHidden=NO;
}
In my project I need to attach another uiviewcontroller to the end of the imagepicker chain.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo
{
uploadPhotoViewController * newView = [[uploadPhotoViewController alloc] initWithNibName:#"uploadPhotoViewController" bundle:nil];
newView.contest = received;
newView.receivedImage = img;
newView.parentImagePicker = picker; // this doesn't help
[picker pushViewController:newView animated:YES];
}
This works great, but when I use the camera as the source it clears the navigation bar and I can not get it to become visible. I have tried the usual:
-(void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
self.wantsFullScreenLayout = FALSE;
self.navigatioController.navigationBar.hidden = false;
self.navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;
[[UIApplication sharedApplication] setStatusBarHidden:NO animated:NO];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:YES];
}
The status bar will come back in the pushed view, but the navigation bar is another beast. I am guessing that since this is a modal that the navigationcontroller is being sent to the view stack underneath. Does anyone know how to address the image picker? I tried passing the image picker in as an object for the view controller as you can see in the first codeblock and then I tried addressing it like this:
self.parentImagePicker.navigationBar.hidden = false;
self.parentImagePicker.navigationBar.barStyle = UIBarStyleBlackTranslucent
But that didn't help either. So I'm stumped. Is their some ivar or something that will allow me to address the picker?
Oh cool, I figured it out. while the call
self.navigatioController.navigationBar.hidden = false;
does not work,
[self.navigationController setNavigationBarHidden:NO];
this one does.
Hey everbody, i'm having problem with a simple question.
I have a NavigationController, 01.xib ans 02.xib.
I set in IB NavigationController to dont display the navigationBar. Well, when i go to 02.xib, i set it to appear.
[self navigationController].navigationBarHidden = NO;
Everything works fine.
But, when i come back to 01.xib with the top button, the bar still appearing in the 01.xib.
How can i fix that?
Thanks!
Use this in first view controller:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[[self navigationController] setNavigationBarHidden:YES animated:animated];
}
I believe this is happening because they are referencing the same navigation controller.
You could set it hidden again in the viewDidAppear method of your 01 class.
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[self navigationController].navigationBarHidden = YES;
}
