uinavigationbar

In my app I have multiple view controllers, and most have a right-hand-side UIBarButtonItem with direct "show" segue actions attached. Having segued to another view and then pressed the '< Back' button, the original button item remains faded out, although still otherwise usable. This only appears to happen under iOS 11.2. I can't see any setting that could be doing this, and in at least one of the cases where this happens there's no specific segue unwinding nor viewDidAppear handling. I'd post some code, but AFAICS it's all just default UINavigationBar behaviour. This is a bug in iOS 11.2 and

I am trying to change the height of there navigation bar for my app. Currently the height is fixed to 44. I can change the width from Xcode but not the height. I have no idea how to change this. Very new to iOS development. Can anyone please help? iAnurag Try this : import UIKit class YourViewController : UIViewController { var navBar: UINavigationBar = UINavigationBar() override func viewDidLoad() { super.viewDidLoad() self.setNavBarToTheView() // Do any additional setup after loading the view. self.title = "test test" } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning(

How can I show a UISearchBar in the NavigationBar? I can't figure out how to do this. Your help is very much appreciated. To put searchBar into the center of navigationBar: self.navigationItem.titleView = self.searchBarTop; To put searchBar to the left/right side of navigationBar: UIBarButtonItem *searchBarItem = [[UIBarButtonItem alloc] initWithCustomView:searchBar]; self.navigationItem.rightBarButtonItem = searchBarItem; As of iOS 7, the UISearchDisplayController supports this by default. Set the UISearchDisplayController's displaysSearchBarInNavigationBar = YES to get this working easily.

I want to add an image background to my navigation bar. Is it right? //set custom background image UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"NavigationBackground.png"]]; [self.navigationBar insertSubview:backgroundView atIndex:0]; [backgroundView release]; Here's the code from the link @luvieere mentioned. Paste this code into to the rootview controller just above @implementation rootviewController @implementation UINavigationBar (CustomImage) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed:@"NavigationBar.png"]; [image

How can I change the position of a UIBarButtonItem in a UINavigationBar? I would like my button to be about 5px higher than its normal position. There is no particularly good way to do this. Your best bet if you really must is to subclass UINavigationBar, and override layoutSubviews to call [super layoutSubviews] and then find and reposition the button's view. This code creates a back button for UINavigationBar with image background and custom position. The trick is to create an intermediate view and modify its bounds. UIButton *backBtn = [UIButton buttonWithType:UIButtonTypeCustom]; UIImage

I am using a Picker View to allow the user to choose the colour theme for the entire app. I am planning on changing the colour of the navigation bar, background and possibly the tab bar (if that is possible). I've been researching how to do this but can't find any Swift examples. Could anyone please give me an example of the code I would need to use to change the navigation bar colour and navigation bar text colour? (The Picker View is set up, I'm just looking for the code to change the UI colours) Thanks. trumpeter201 Navigation Bar: navigationController?.navigationBar.barTintColor = UIColor
