I have an iOS project with UINavigationController.
When I pushviewcontroller with
animated = YES
[self.navigationController pushViewController:viewController animated:YES];
the top leftbarbuttonitem (with image) is well positioned.
But if I set pushviewcontroller with
animated = NO
[self.navigationController pushViewController:viewController animated:NO];
the top leftbarbuttonitem (with image) is not positioned exactly the same place with previous one. Does anyone have any idea?
SAMPLE CODE
- (void)addBackButtonWithoutAnimation {
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
UIImage *closeImage = [UIImage imageNamed:#"icon_back"];
UIBarButtonItem *closeBackButton = [[UIBarButtonItem alloc] initWithImage:closeImage style:UIBarButtonItemStylePlain target:self action:#selector(closeBackButtonwithoutAnimationDidClick)];
self.navigationItem.leftBarButtonItem = closeBackButton;
self.navigationItem.hidesBackButton = YES;}

I'm using UIImagePickerController inside a UIPopoverController to select image just from photo albums. When I launch app on device running iOS 8, the Cancel button on the top right of the pop over appeared normally like this:
But when I launch the app on device running iOS 7, the Cancel button disappeared:
The code I used to show the picker:
UIImagePickerController *pickerController = [[UIImagePickerController alloc] init];
[pickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
pickerController.delegate = self;
_popOver = [[UIPopoverController alloc] initWithContentViewController:pickerController];
_popOver.delegate = self;
pickerController.navigationBar.tintColor = [UIColor redColor];//Cancel button text color
[pickerController.navigationBar setTitleTextAttributes:#{NSForegroundColorAttributeName: [UIColor blackColor]}];// title color
if (isImage) {
[pickerController setMediaTypes:#[(NSString*)kUTTypeImage]];
} else
[pickerController setMediaTypes:#[(NSString*)kUTTypeMovie]];
[_popOver presentPopoverFromRect:CGRectMake(1024/2, 768/2, 1, 1) inView:self.view permittedArrowDirections:0 animated:YES];
What can I do to show that Cancel button on iOS7? My app design doesn't allow user to dismiss the popover by tapping anywhere outside the popover view.
Thank you.
#JozoL Write the Below Code this works
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
UINavigationItem *pickerNavBarTopItem;
// add done button to right side of nav bar
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Cancel"
style:UIBarButtonItemStylePlain
target:self
action:#selector(doSomething)];
UINavigationBar *bar = navigationController.navigationBar;
[bar setHidden:NO];
pickerNavBarTopItem = bar.topItem;
pickerNavBarTopItem.rightBarButtonItem = doneButton;
}
-(void)doSomething{
}
For swift2.x you can try below code, Its work for me
pickerController.navigationBar.tintColor = UIColor.blueColor()
In my case, UIImagePickerController was not showing its cancel button
. So I tried adding this line to code:
pickerController.navigationBar.barStyle = UIBarStyleDefault;
And this worked for me.Try setting color of Cancel button like this
pickerController.navigationBar.tintColor = [UIColor blackColor];
Try using this code and let me know if it helps you.
I add a uinavigationcontroller as a subview on a uiviewcontroller (rootviewcontroller of aap) and this view controller is a subview as a rootviewcontroller on self.window.
in Appdelegate I use:
self.window.rootViewController = self.rootVC;
and in viewdidload of my RootViewController I wrote:
[self.navVC.navigationController.navigationBar setBarStyle:UIBarStyleBlack];
[self.navVC.navigationController.navigationBar setTranslucent:YES];
self.navVC.navigationController.navigationBarHidden = NO;
[app.rootVC.view addSubview:self.navVC.view];
self.navVC.delegate = self;
Here, navigationbar is displaying but I am unable to display uibarbutton items on navigation bar. Example code:
leftBtn = [[UIBarButtonItem alloc] initWithTitle:#"Left" style:UIBar
flxBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBa
rightBtn1 = [[UIBarButtonItem alloc] initWithTitle:#"Right" style:UIBar
rightBtn = [[UIBarButtonItem alloc] initWithTitle:#"Right" style:UIBar
[self.navVC.navigationItem setLeftBarButtonItem:leftBtn];
[self.navVC.navigationItem setRightBarButtonItems:#[rightbtn1,rightbtn,flxBtn]];
Can somebody help me out to resolve my problem. How can I change appearance of navigationbar and how the uibarbutton items can be displayed ?
You will simply need to change your
[self.navVC.navigationItem setRightBarButtonItems:#[rightbtn1,rightbtn,flxBtn]];
to
[self.navigationItem setRightBarButtonItems:#[rightbtn1,rightbtn,flxBtn]];
and
[self.navVC.navigationItem setLeftBarButtonItem:leftBtn];
to
[self.navigationItem setLeftBarButtonItem:leftBtn];`
In my app I have a tableViewController where I have added a UINavigationController and a BackButton programmatically:
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:self];
[self.view addSubview:navController.view];
self.title =#"A";
UIBarButtonItem *btn = [[UIBarButtonItem alloc] initWithTitle:#"back" style:UIBarButtonItemStyleBordered target:self action:#selector(backPressed:)];
self.navigationItem.leftBarButtonItem = btw;
But the output is not the same as the default navigation bar and as the default back button.
This is what I mean with default navigation bar and default back button:
And this is how it looks with my custom code:
How could I get the same output with code?
Try to set up navigationBar frame with following code:
self.navigationController.navigationBar = CGRectMake(self.navigationController.navigationBar.frame.origin.x, self.navigationController.navigationBar.frame.origin.y, self.navigationController.navigationBar.frame.size.width, 64);
and use this method:
-(UIBarPosition)positionForBar:(id<UIBarPositioning>)bar
{
return UIBarPositionTopAttached;
}
Don't forget to set up delegate of navigation bar
self.navigationController.navigationBar.delegate = self;
i have a UI Image picker and its being shown inside a UI popoverController, i need a back button on UIimage picker navbar, so i can go back to previous popover.
let me explain in details.
1) i have a popup in which i tap and raise a notification, this notification is read on a view controller where i want this camera image picker popup. following is my code
-(void)registerNotificationForCameraSource
{
[[NSNotificationCenter defaultCenter]addObserver:self selector:#selector(mediaSourceCallback:) name:NOTIFICATION_FOR_CAMERA_SOURCE object:nil];
}
#pragma mark - Image picker Popover
-(void)mediaSourceCallback:(NSNotification *)notificationObj
{
capturedImages = [[NSMutableArray alloc] init];
pickerObj = [[UIImagePickerController alloc] init];
// [pickerObj setContentSizeForViewInPopover:CGSizeMake(320,480)];
pickerObj.delegate = self;
if ([notificationObj.object isEqualToString:#"UIImagePickerControllerSourceTypeCamera"])
{
pickerObj.sourceType = UIImagePickerControllerSourceTypeCamera;
pickerObj.modalPresentationStyle = UIModalPresentationFullScreen;
pickerObj.showsCameraControls = YES;
[self presentViewController:pickerObj animated:YES completion:nil];
}
else
{
[[UINavigationBar appearanceWhenContainedIn:[ApplicationDiscriptionPopupViewController class], nil] setBarTintColor:[UIColor redColor]];
pickerObj.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:#"Back" style:UIBarButtonItemStyleDone target:self action:#selector(imagePickerBackButtonTapped)];
[pickerObj.navigationController.navigationBar setBarTintColor:[UIColor redColor]];
[pickerObj setNavigationBarHidden:NO animated:YES];
//navigationControllerObj = [[UINavigationController alloc] initWithRootViewController:applicationDiscriptionPopupViewControllerObj];
_popoverControllerObj.popoverContentSize = CGSizeMake(320,480);
pickerObj.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[pickerObj presentedViewController];
[_popoverControllerObj setContentViewController:pickerObj animated:YES];
}
}
-(void)imagePickerBackButtonTapped
{
[pickerObj popToViewController:applicationDiscriptionPopupViewControllerObj animated:YES]; }
pickerObj is UI Image picker
applicationDiscriptionPopupViewControllerObj is view controller of my previous popover view. from where i came. now i wana go back to this view in the popup, when i tap on back button in nav bar.
but i dnt hav any nav bar. plz help
If you are adding a UIImagePickerController via presentViewController inside a UIViewController then you should see the default navigation bar. You should implement :
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
UINavigationItem *navBarTopItem;
// you cannot add a custom back button with native back button look like, so use image over
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"back_arrow.png"]
style:UIBarButtonItemStyleBordered
target:self
action:#selector(backAction)];
navBarTopItem.title = #"Albums"; // "Camera
navBarTopItem.leftBarButtonItem = backButton;
}
Add a back button action handler
-(void)backAction{
[self.navigationController popViewControllerAnimated:YES];
}
Hope that answer ur Q.
I want to add a right bar button item to the navigation bar, so that on click, it performs certain a function.
I have created the following code to add the right bar button item, but after it is done, the bar button item is not getting displayed in navigation bar:
-(void)viewDidload{
self.navigationItem.rightBarButtonItem =
[[[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
target:self
action:#selector(Add:)] autorelease];
}
-(IBAction)Add:(id)sender
{
TAddNewJourney *j=[[TAddNewJourney alloc]init];
[app.navigationController pushViewController:j animated:YES];
[j release];
}
Let assume, you have a UIViewController, like this:
UIViewController *vc = [UIViewController new];
And you added it to navigation controller:
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:vc];
In this way rightBarButtonItem will NOT getting displayed:
nc.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"xyz" style:UIBarButtonItemStyleDone target:self action:#selector(xyz)];
BUT this way IT WILL appear:
vc.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"xyz" style:UIBarButtonItemStyleDone target:self action:#selector(xyz)];
Use your own viewcontroller instead of the navigationcontroller to refer navigationItem.
-(void)viewDidLoad
{
[super viewDidLoad];
app.navigationController.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(Add:)] autorelease];
}
-(IBAction)Add:(id)sender
{
TAddNewJourney *j=[[TAddNewJourney alloc]init];
[app.navigationController pushViewController:j animated:YES];
[j release];
}
Try the other answers. I posted this answer so that it will work if your viewcontroller does not have a navigation controller which i think is the problem.
Add this code in viewdidload
UIBarButtonItem *chkmanuaaly = [[UIBarButtonItem alloc]initWithTitle:#"Calculate" style:UIBarButtonItemStylePlain target:self action:#selector(nextview:)];
self.navigationItem.rightBarButtonItem = chkmanuaaly;
Most of the answers here address setting the UINavigationBar's rightBarButtonItem from within the new VC after it is shown. My need, which was actually answered by János, is to set the UINavigationItem items from the CALLING UIViewController. Hence, the following code (Thanks, János).
// from within self (aka the calling controller):
UIViewController *c = [[[UIViewController alloc] init...] autorelease];
c.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(dismissModalViewControllerAnimated:)] autorelease];
c.navigationItem.title = #"Title Goes Here";
UINavigationController *nav = [[[UINavigationController alloc] initWithRootViewController:c] autorelease];
nav.navigationBarHidden = FALSE;
[self presentModalViewController:nav animated:YES];
Now, granted, this may seem redundant to János' answer, but I need more rep points in order o mark his response up. ;-)
UIBarButtonItem *add=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(addUser)];
self.navigationItem.rightBarButtonItem=add;
[add release];
I guess it will be more complete response and it should help in any situation:
-(void)viewDidLoad{
//Set Navigation Bar
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 64)];
//Set title if needed
UINavigationItem * navTitle = [[UINavigationItem alloc] init];
navTitle.title = #"Title";
//Here you create info button and customize it
UIButton * tempButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
//Add selector to info button
[tempButton addTarget:self action:#selector(infoButtonClicked) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem * infoButton = [[UIBarButtonItem alloc] initWithCustomView:tempButton];
//In this case your button will be on the right side
navTitle.rightBarButtonItem = infoButton;
//Add NavigationBar on main view
navBar.items = #[navTitle];
[self.view addSubview:navBar];
}
Use the following code:
UIBarButtonItem *add=[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(addUser)];
self.navigationItem.rightBarButtonItem=add;
[add release];
Hope this helps you out.
Enjoy!
Swift:
let rightButton = UIBarButtonItem(image: UIImage(named: "imageName"),
style: .plain,
target: self,
action: #selector(buttonTapped))
navigationItem.setRightBarButton(rightButton, animated: false)
#objc func buttonTapped(sender: UIBarButtonItem!) {
// Implement action
}
UIButton *dButton=[UIButton buttonWithType:0];
dButton.frame=CGRectMake(50,50,50,50);
[dButton addTarget:self action:#selector(clickdButton:)
forControlEvents:UIControlEventTouchUpInside];
[dButton setImage:[UIImage imageNamed:#"iconnavbar.png"]
forState:UIControlStateNormal];
dButton.adjustsImageWhenHighlighted=NO;
dButton.adjustsImageWhenDisabled=NO;
dButton.tag=0;
dButton.backgroundColor=[UIColor clearColor];
UIBarButtonItem *RightButton=[[[UIBarButtonItem alloc] initWithCustomView:dButton]autorelease];
self.navigationItem.rightBarButtonItem=RightButton;
and then:
-(IBAction)clickdButton:(id)sender{
classexample *tempController=[[classexample alloc] init];
[self.navigationController pushViewController:tempController animated:YES];
[tempController autorelease];
}
