I had a little problem which is my uicollectionviewcontroller top bar doesn't appear in simulator and device. I already set the top bar to translucent navigation bar for uicollectionviewcontroller, then I dragged navigation item to navigation bar and finally I set an image for left bar button items to function as back button. Below is there screenshot.
Top Bar Storyboard:
Simulator Result:
It doesn't look like you have a navigation controller, to add a navigation bar programatically without a navigation controller controlling the view hierarchy you can do the following.
-(void) viewWillAppear:(BOOL)animated {
UINavigationBar *navBar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
[UINavigationBar appearance].barTintColor = [UIColor lightGrayColor];
[self.view addSubview: navBar];
UIBarButtonItem *cancelItem = [[UIBarButtonItem alloc] initWithTitle:#"Cancel"
style:UIBarButtonItemStyleBordered
target:self
action:nil];
UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStyleBordered
target:self action:nil];
UINavigationItem *navItem = [[UINavigationItem alloc] initWithTitle:#"Navigation Title"];
navItem.rightBarButtonItem = doneItem;
navItem.leftBarButtonItem = cancelItem;
navBar.items = [NSArray arrayWithObjects: navItem,nil];
[UIBarButtonItem appearance].tintColor = [UIColor blueColor];
}
To add the navigation controller (which will add the bar), highlight the UICollectionViewController in storyboard, and select Editor->Embed in->Navigation Controller from the menus.

This is the code I am using in viewWillAppear:
UINavigationBar *navbar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 1420, 50)];
//do something like background color, title, etc you self
[[UINavigationBar appearance] setBarTintColor:[UIColor underPageBackgroundColor]];
self.navigationController.navigationBar.translucent = NO;
[self.view addSubview:navbar];
UINavigationItem *item = [[UINavigationItem alloc]
init];
navbar.items= #[item];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc]
initWithTitle:#"Back"
style:UIBarButtonItemStylePlain
target:self
action:#selector(backBtnClicked:)];
item.leftBarButtonItem = backButton;
I want to remove the shadowImage. The line underneath the nav bar but ONLY in one view controller. How do I do this?
I've already tried this but it changes all view controllers, to be like, invisible:
[[UINavigationBar appearance] setBackgroundImage: [UIImage new]
forBarMetrics: UIBarMetricsDefault];
[UINavigationBar appearance].shadowImage = [UIImage new];
Any help would be greatly appreciated!
I had an issue with white space appearing under my nav bar. Is this what you mean by a line? I solved it within xCode's Interface Builder by:
Selecting the view controller in the storyboard
Going to the attributes section of the right toolbar
Check the box "Under Opaque Bars" in the "Extend Edges" section.
I also added the following code in my viewDidLoad method:
self.automaticallyAdjustsScrollViewInsets = NO;
I have a button and when pressed it presents a new viewController, like a pop up window.
- (IBAction)btnPressed:(id)sender
{
PopUpObj = [[PopUpViewController alloc] init];
[self.navigationController presentViewController:PopUpObj animated:YES completion:nil];
}
The View appears as it should but it has no nav bar with back button.
In the PopUpViewController I create a nav bar like this:
- (void)viewDidLoad
{
self.view.backgroundColor = [UIColor whiteColor];
UINavigationBar *navbar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 64)];
[navbar setBarStyle:UIBarStyleDefault];
[self.view addSubview:navbar];
UIBarButtonItem* myBackButton = [[UIBarButtonItem alloc]
initWithTitle:#"Back"
style:UIBarButtonItemStyleBordered
target:nil
action:nil];
self.navigationItem.backBarButtonItem = myBackButton;
[super viewDidLoad];
}
The nav bar appears but the back button item doesn't appear at all. What's wrong?
The backBarButtonItem is displayed when you push another viewController onto the navigation stack. Think of it as the button that will be used to get back to your PopUpViewController, not the button displayed whilst showing your PopUpViewController. Change self.navigationItem.backBarButtonItem to self.navigationItem.leftBarButtonItem.
For some reason I can't use UINavigationBar on my view and I use UIToolBar instead. I was using dummy left button with clear tintColor and title button with black tintColor to properly center the title and hide the dummy left bar button, but it's not working anymore and both the dummy left button and the title button get either the main tintColor or if I disable them, they become gray.
How can I make them ideally disabled as buttons and set the proper tintColor (clear and black)?
- (void)addToolbar
{
CGFloat barHeight = 44.0;
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(self.view.bounds.origin.x, self.view.bounds.size.width - barHeight, self.view.bounds.size.height, barHeight)];
UIBarButtonItem *flexibleSpaceButtonItem = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil action:nil];
// Done button on the right
UIBarButtonItem *doneButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(done)];
// dummy button on the left to have centered title
UIBarButtonItem *dummyButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:nil action:nil];
dummyButtonItem.enabled = NO;
dummyButtonItem.tintColor = [UIColor clearColor];
// title button
UIBarButtonItem *titleButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Title text here" style:UIBarButtonItemStylePlain target:nil action:nil];
titleButtonItem.enabled = NO;
titleButtonItem.tintColor = [UIColor blackColor];
// set toolbar items
toolbar.items = #[dummyButtonItem,flexibleSpaceButtonItem, titleButtonItem, flexibleSpaceButtonItem,doneButtonItem];
[self.view addSubview:toolbar];
}
When you specify a tint for a view, the tint is automatically propagated to all subviews in the view’s hierarchy. Because UIWindow inherits from UIView, you can specify a tint color for the entire app by setting the window’s tint property using code like this:
Under application:didFinishLaunchingWithOptions:
window.tintColor = [UIColor purpleColor];
Source - iOS Transitions . Check it out under Using Tint Color section
Based on your feedback I found that by doing this in AppDelegate:
self.window.tintColor = [UIColor colorWithRed:255/255.0 green:59/255.0 blue:48/255.0 alpha:1.0];
[[UITextField appearance] setTintColor:[UIColor colorWithRed:66/255.0 green:107/255.0 blue:242/255.0 alpha:1.0]];
the second line causes my issue. I now need to find out why did I put the second line there :). Thanks for your help.
I am new to iOS development.I have create a navigation bar in my iPad application view.I don't need navigation controller that's why i have added only navigation bar. Now i want to add button in that navigation bar.I tried a lot but no success. Is it possible to add only navigation bar with button ? If yes then suggest me some sample code.
"i don't have navigation controller or need it. i just want to add navigation bar in only one view."
Bellow is my code which i write for adding navigation bar in ViewDidLoad()
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 1026, 50)];
[navBar setTintColor:[UIColor blackColor]];
[navBar setDelegate:self];
[self.view addSubview:navBar];
Thanks in advance....
I used the Interface Builder to make a static tableView in a UITableViewController.
This UITableViewController is shown modally. Then I added a NavigationBar without the UINavigationController behind it as follows:
//Creating the plain Navigation Bar
UINavigationBar *headerView = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
//The UINavigationItem is neede as a "box" that holds the Buttons or other elements
UINavigationItem *buttonCarrier = [[UINavigationItem alloc]initWithTitle:#"Sign-In"];
//Creating some buttons:
UIBarButtonItem *barBackButton = [[UIBarButtonItem alloc] initWithTitle:#"Zurück" style:UIBarButtonItemStyleDone target:self action:#selector(signInBackPressed:)];
UIBarButtonItem *barDoneButton = [[UIBarButtonItem alloc] initWithTitle:#"Fertig" style:UIBarButtonItemStylePlain target:self action:#selector(signInDonePressed:)];
//Putting the Buttons on the Carrier
[buttonCarrier setLeftBarButtonItem:barBackButton];
[buttonCarrier setRightBarButtonItem:barDoneButton];
//The NavigationBar accepts those "Carrier" (UINavigationItem) inside an Array
NSArray *barItemArray = [[NSArray alloc]initWithObjects:buttonCarrier,nil];
// Attaching the Array to the NavigationBar
[headerView setItems:barItemArray];
// Adding the NavigationBar to the TableView
[self.tableView setTableHeaderView:headerView];
I hope this helps somebody!
UIBarButtonItem *bi1 = [[UIBarButtonItem alloc] initWithTitle:#"Edit" style:UIBarButtonItemStyleBordered target:self action:#selector(editButton)];
bi1.style = UIBarButtonItemStyleBordered;
bi1.tintColor = [UIColor colorWithWhite:0.305f alpha:0.0f];
self.navigationItem.rightBarButtonItem = bi1;
[bi1 release];
You can add buttons to navigation bar as follows:
UIBarButtonItem *btnSave = [[UIBarButtonItem alloc]
initWithTitle:#"Save"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(save_Clicked:)];
navBar.rightBarButtonItem = btnSave;
[btnSave release];
UIBarButtonItem *btnCancel = [[UIBarButtonItem alloc]
initWithTitle:#"Cancel"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(cancel_Clicked:)];
navBar.leftBarButtonItem = btnCancel;
[btnCancel release];
When an item from a UITableView is selected, a detail view is loaded which has a banner bar at the top with a back button on it to navigate back to the table.
How do I add other buttons to that banner bar?
As Andrew said, you can add custom views to the navigation bar. For example, if you are looking to add multiple buttons to the right side of the navigation bar, you can do something like this:
// right side of nav bar
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 106, 44)];
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:3];
UIBarButtonItem *deleteButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemTrash
target:self
action:#selector(deleteAction:)];
deleteButton.style = UIBarButtonItemStyleBordered;
[buttons addObject:deleteButton];
[deleteButton release];
UIBarButtonItem *spacer = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
target:nil
action:nil];
[buttons addObject:spacer];
[spacer release];
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
target:self
action:#selector(cancelAction:)];
cancelButton.style = UIBarButtonItemStylePlain;
[buttons addObject:cancelButton];
[cancelButton release];
[toolbar setItems:buttons animated:NO];
toolbar.barStyle = -1;
[buttons release];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar];
[toolbar release];
Make sure to adjust the width (106 above) if you need more or wider buttons, and then provide methods for the selectors (deleteAction: and cancelAction: above).
From your description, it sounds like you have a UINavigationController correctly set up. That "banner bar" you are describing is properly called a navigation bar.
From within the detail view, you can use:
UIBarButtonItem* button = [[[UIBarButtonItem alloc] initWithTitle:"HiMom" style:UIBarButtonItemStylePlain target:self action:#selector(onHiMom:)] autorelease];
self.navigationItem.rightBarButtonItem = button;
You can also add custom views (instead of a button) plus a few other settings. I suggest poking around the documentation for UINavigationItem, UINavigationBar, and UIBarButtonItem for ideas.
