I want a black status bar with white text.
General approach I used is having light style status bar to create a custom black view and to add it to the top of the view controller
CGFloat statusBarHeight = [UIApplication sharedApplication].statusBarFrame.size.height;
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, statusBarHeight)];
view.backgroundColor = [UIColor blackColor];
[self.view addSubview:view];
If the view controller is embedded in a navigation controller I do
CGFloat statusBarHeight = [UIApplication sharedApplication].statusBarFrame.size.height;
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, -statusBarHeight, [UIScreen mainScreen].bounds.size.width, statusBarHeight)];
view.backgroundColor = [UIColor blackColor];
[self.navigationController.navigationBar addSubview:view];
However this seems to be not a very elegant solution, maybe there are better approaches?
One way that you can do it by adding view on keywindow. It doesn't matter whether your app is running under UINavigationController or under UIViewController. I have did this by making extension of UIStatusBarStyle as below.
extension UIStatusBarStyle {
static func setbackground() {
let view = UIView.init(frame: UIApplication.shared.statusBarFrame)
view.backgroundColor = UIColor.black
UIApplication.shared.keyWindow?.addSubview(view)
}
}
Now call this method in appdelegate from method didFinishLaunchingWithOptions.
UIStatusBarStyle.setbackground()
Also, make sure that in your info.plist file you have set
View controller-based status bar appearance = NO
Status bar style = Opaque black style

I saw a solution to change the height of navigation bar. But nothing worked for me. Now my application has one view controller connected with a navigation controller. I have not yet implemented any other code in my project. Before starting my project I need to change my height of my navigation bar.
edited:
.h:
- (CGSize)sizeThatFits:(CGSize)size ;
.m:
#implementation UINavigationBar (customNav)
- (CGSize)sizeThatFits:(CGSize)size {
CGSize newSize = CGSizeMake(370,40);
return newSize;
}
#end
UIView *NavView = [[UIView alloc] initWithFrame:CGRectMake(0, 0 , [UIScreen mainScreen].bounds.size.width , 44)];
NavView.backgroundColor = [UIColor clearColor];
NavView.userInteractionEnabled = YES;
[self.navigationController.navigationBar addSubview:NavView];
UIButton *DateBtn = [[UIButton alloc]initWithFrame:CGRectMake(0, 10, 90, 30)];
DateBtn.backgroundColor = [UIColor clearColor];
[DateBtn setTitle:#"Jan 05" forState:UIControlStateNormal];
DateBtn.titleLabel.font = [UIFont fontWithName:BrushScriptStd size:18];
[DateBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[NavView addSubview:DateBtn];
You can not change UINavigation height but you can add you custom view on UINavigation bar
Very simple solution to this problem is you can create view from StoryBoard or from Code.
And add the view to your viewController.
You have to disable default navigation Bar from you project. You can do it by Storyboard also. Select your navigation bar and change the Status Bar to none:
And If you want to do via code then in your didFinishLaunching wirte this code:
UIStoryboard *tStoryBoard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
RootVC* RootVCObj = [tStoryBoard instantiateViewControllerWithIdentifier:#"RootVC"];
UINavigationController *navC = [[UINavigationController alloc] initWithRootViewController:RootVCObj];
navC.navigationBarHidden = YES;
After this add as many as Buttons to your view
Main cons of this is that you have to make custom view for all Screens you currently have
I have a container UIViewController (IntroViewController), in which I load a UIPageViewController (PageViewController). In the UIPageViewController, I have IntroPageContentViewControllers and a LastIntroPageContentViewController.
I want to have a background image in the UIPageViewController. If I put it in IntroViewController, it isn't viewable. I can't put it in the UIPageViewController, and when I put it in one of the ContentViewControllers it scrolls in and out with each page. I want it to be in one place and only scroll the content.
Where do I put the UIImageView and where should I bringSubviewToFront or something alike?
Simply put the UIImageView into container UIViewController and set view.backgroundColor property to [UIColor clearColor] for both content view controllers.
Here you have an example how it works:
https://github.com/Wojdan/stackAnswers/tree/master/33912671
UIView *view = [[UIView alloc] init];
view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
UIImageView *imageView1 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"login_backgroung"]];
imageView1.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
[view addSubview:imageView1];
// Create page view controller
self.pageViewController = [self.storyboard
instantiateViewControllerWithIdentifier:#"PageViewController"];
self.pageViewController.dataSource = self;
self.pageViewController.view.backgroundColor = [UIColor clearColor];
[self.pageViewController.view insertSubview:view atIndex:0];
UIPageControl *pageControl = [UIPageControl appearance];
pageControl.pageIndicatorTintColor = [UIColor whisperWhite];
pageControl.currentPageIndicatorTintColor = [UIColor whisperDarkGray];
pageControl.backgroundColor = [UIColor clearColor];
Ideally, You should be adding UIPageViewControlleras child of it parentViewController. In your case IntroViewController is parent and PageViewController will become child of it.
Now, you set IntroViewController background colour from image like below :
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"background"]];
And then, you can clear background colours for content view controllers which are you planning to add into UIPageViewController.
However, you may have to comment below delegate to remove page control from bottom of `UIPageViewController'
- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController
{
}
Hope this helps.
I have this code in viewDidLoad:
[self.navigationController setNavigationBarHidden:YES];
self.edgesForExtendedLayout = UIRectEdgeNone;
self.view.autoresizingMask = UIViewAutoresizingFlexibleHeight;
self.view.backgroundColor = [UIColor whiteColor];
//we need to add white background behind the status bar
CGFloat statusBarHeight = [UIApplication sharedApplication].statusBarFrame.size.height;
UIView* statusBarWhiteBackGround = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, statusBarHeight)];
[statusBarWhiteBackGround setBackgroundColor:[UIColor whiteColor]];
[self.view addSubview:statusBarWhiteBackGround];
UIView * redBackGroundColor = [[UIView alloc] init];
[redBackGroundColor setBackgroundColor:[UIColor redColor]];
redBackGroundColor.frame =CGRectMake(0,statusBarHeight , self.view.frame.size.width, self.view.frame.size.height-statusBarHeight);
[self.view addSubview:redBackGroundColor];
statusWhiteBackGround view is used to change the color of the status bar.
here is the result of the above code:
but when the app enter background and then back to foreground, the redBackGroundColor view change it's orging.y as you can see in the bellow picture:
what's the problem ?thanks
Create a UIView programatically on method
-(void)viewDidLayoutSubviews{
screen=[[UIScreen mainScreen] bounds];
//Simple view
self.customView = [[CustomAlertOKView alloc]initWithFrame:CGRectMake(0, 20, screen.size.width, screen.size.height)];
[self.view addSubView:customView];
}
or
Create a view using storyboard and set the x as 0, y value as 20,width and height based on the screen size
#IBOutlet UIView *customView;
set the outlet in the storyboard,
Then set the background color of the custom view to redcolor and main view to white color
self.view.backgroundColor = [UIColor whiteColor];
customView.backgroundColor = [UIColor redColor];
I have a UITableViewController with a UISearchDisplayController and UISearchBar. I'm seeing a white line under the navbar when I present the view in a UITabBarController. When I present the view modally in a UINavigationController, the line is either gray or black (I can't tell) and it looks perfectly normal. Any ideas?
I had the same problem, couldn't figure out from where it did came from (it was present everywhere and it was NOT the shadowImage), ended up with the following fix (in my UINavigationController subclass)
// Fixes strange line under NavigationBar
{
UIView * view = [[UIView alloc] init];
view.backgroundColor = self.navigationBar.barTintColor;
CGRect rect = view.frame;
rect.origin.x = 0.f;
rect.origin.y = self.navigationBar.frame.size.height;
rect.size.width = self.navigationBar.frame.size.width;
rect.size.height = 1.f;
view.frame = rect;
[self.navigationBar addSubview:view];
}
I had the same problem too, after trying with a lot of methods,I find this way solved my problem
[[UISearchBar appearance] setBackgroundColor:[UIColor yourColor]];
write it in your viewDidLoad.
The white line is probably the shadowImage of navigation bar.
Try setting it as:
self.navigationController.navigationBar.shadowImage = [UIImage new];
Try setting the clipsToBounds property on the UISearchBar to YES.
Use following line of the code :
UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 43, 320, 1)];
[overlayView setBackgroundColor:[UIColor whiteColor]]; // set color accordingly
[navBar addSubview:overlayView]; // navBar is your UINavigationBar instance
[overlayView release];

let hideLineView = UIView(frame: CGRect(x: 0, y: navigationController!.navigationBar.frame.size.height, width: view.frame.size.width, height: 1))
hideLineView.backgroundColor = UIColor.white
navigationController!.navigationBar.addSubview(hideLineView)
How come this code is not producing a UINavigationBar on my UIView?
//create the view
UIView *view = [[UIView alloc] init];
view.backgroundColor = [UIColor whiteColor];
//everything for tabbar
UINavigationBar *navBar = [[UINavigationBar alloc] init];
//add the components to the view
[view addSubview: navBar];
//show the view
self.view = view;
I see the white view but no NavBar. Any help? What am I doing wrong?
Set the frame of navigation bar and add it as a subview of the view for it to be seen.Set a frame for any view to be positioned in its super view's coordinate system.
[navBar setFrame:CGRectMake(0,0,CGRectGetWidth(view.frame),44)];
[self.view addSubview:navBar];
Also its a navigation bar, I do not know what tab bar you are willing to see from this code you posted.
