So I have the subview (side menu) pulled out on top of the main view inside of a Navigation Controller. Is it possible to hide the status bar on the slide out menu but continue to show it on the main view?
Note: one view is currently on top of the other
override var prefersStatusBarHidden: Bool {
return true
}
try this ... Can't Hide Status Bar—Swift 3,
You can hide status bar in a condition.. You need to add another Window Object over the status bar.
let stautsBarWindow = UIWindow(frame: UIScreen.main.bounds)
stautsBarWindow.backgroundColor = UIColor.clear
stautsBarWindow.rootViewController = yourSideMenuViewController
stautsBarWindow.windowLevel = UIWindowLevelStatusBar
stautsBarWindow.isHidden = false
This will create another window object at the top of your status bar. So just slide it pretty left side so that you can see only half of it/ reduce its width to half of the screen so that you can only see half visible area and show full viewController inside this area. Which ever logic you think is right just use that.

So the way I understand navigation bar (navigation item) is that it has three locations you can modify, which is left (leftBarButtomItem), middle (titleView), and right (rightBarButtonItem).
Now what I'm going to achieve is that I want to just add a simple progress bar line at the very bottom of navigation bar, but still inside navigation bar. I want to make this like an extension of navigation bar that I can reuse on other screens. But I want that left, middle, and right "views" are still working like usual. e.g. I don't want that if I change the title view content manually in other view controller, then the line disappears / stops working for that other view controller. So this will feel like an independent overlay added on top of navigation bar as subview, separated from leftBarButtonItem, titleView, and rightBarButtonView, sort to speak.
Is it possible to do that in navigation item?
This is a example of how to add a Image instead of a Title String
fileprivate func setupTitle(){
let logo = UIImage(named: "my_incredible_logo")
let imageView = UIImageView(image:logo)
imageView.contentMode = .scaleAspectFit
self.navigationItem.titleView = imageView
self.navigationController?.navigationBar.prefersLargeTitles = false
}
I'm hiding the Navigation Bar on one of the screens, and if is set:
navigationController?.navigationBarHidden = true
The status bar becomes black. Also, the image doesn't fit all the screen (see the screenshot).
If I comment this line, Navigation bar stays on screen, and the status bar is white.
Full code:
override func viewWillAppear(animated: Bool) {
navigationController?.navigationBarHidden = true
navigationController?.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .Default)
navigationController?.navigationBar.translucent = true
navigationController?.navigationBar.backgroundColor = UIColor.clearColor()
navigationController?.view.backgroundColor = UIColor.clearColor()
All constraints of ImageView are set to 0 and it's set to fill the screen:
So, I want to put ImageView under the status bar and make the status bar icons/text white. What I'm doing wrong?
You're not doing anything "wrong". You have set the top of the image view to the bottom of the view controller's top layout guide. Well, that's the bottom of the status bar — exactly where you see the top of the image view.
If you want the image view to underlap the status bar, its top needs to be pinned to the top of the main view, not the top layout guide.
And if you want the status bar to change text color, you need to implement preferredStatusBarStyle to return .LightContent. If this means that the result of preferredStatusBarStyle has changed, you would need to call setNeedsStatusBarAppearanceUpdate to alert the runtime to this fact.
To place the image view under the status bar, and have the image view fill the UIViewControllers view:
Clear all constraints for the image view
Add a constraint to set the image view to have the same width as the parent view
Add a constraint to set the image view to have the same height as the parent view
Pin the image view to the nearest neighbor as shown below. Add the constraints
The final constraints will look like the following:
I want to have the Tab Bar at the top of the screen. One post suggested to do the followings (I put the following code in the viewDidLoad() of the UITabBarController) :
CODE
let tabBar = self.tabBar
// yStatusBar indicates the height of the status bar
let yStatusBar = UIApplication.sharedApplication().statusBarFrame.size.height
// Set the size and the position in the screen of the tab bar
tabBar.frame = CGRectMake(0, yStatusBar, tabBar.frame.size.width, tabBar.frame.size.height)
There are 2 problems with this solution:
The bottom of the screen is left with a black region where the tab bar was
The Tab bar covers the view at the top of the screen - the constraints of that view is relative to the device but they should be relative to the Tab bar. However when the screen is designed in the IB there is no Tab bar to relate to.
Is there a way to overcome these problems? P.S. I am new to IOS
let tabBar = self.tabBarController?.tabBar
// Set the size and the position in the screen of the tab bar
tabBar?.frame = CGRect(x: 0, y: self.view.frame.height, width: (tabBar?.frame.size.width)!, height: (tabBar?.frame.size.height)!)
Although it is against the human interface guidelines there exist a hack if you really want to.
You could create a blank UIView in your storyboard (with proper constraints set up) that would essentially be the placeholder for the tabBar when loaded.
You then set top constraints for your other views relative to this view that you have setup.
This works, but probably not best practice to do so
In my app I have this kind of bug:
When I scroll down, the content of table is seen above the search bar. What can be the reason?
override func viewDidLoad() {
super.viewDidLoad()
self.resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
controller.searchBar.barTintColor = UIColor(red: 52.0/255.0, green: 73.0/255.0, blue: 94.0/255.0, alpha: 1.0)
self.tableView.tableHeaderView = controller.searchBar
return controller
})()
self.tableView.reloadData()
}
The iOS Human Interface Guidelines list 3 methods to prevent content from showing through the status bar.
Use a navigation controller to display content. A navigation controller automatically displays a status bar background and it
ensures that its content views don’t appear behind the status bar. (To
learn more about navigation controllers, see Navigation Controllers.)
Create a nondistracting custom image—such as a gradient—and display it behind the status bar. To ensure that the image stays
behind the status bar, you could use a view controller to keep the
image above a scrolling view or you could use a scrolling view to keep
it pinned to the top.
Position content to avoid the status bar area (that is, the area defined by the app’s statusBarFrame property). If you do this, you
should use the window’s background color to provide a solid color
behind the status bar.
You should make the status bar not translucent.
The status bar's color is a property of UIApplication. You need to set it to a valid UIStatusBarStyle.
The new UISearchController has been designed to work with a UITableView and a UINavigationBar. Its functionality depends on your navigation bar being present. when the search bar has content in its text field, it will be latched on top of the page under the navigation bar. well, you don't have any navigation bar, it will latch to the top view guide and it always takes into account the status bar (if present) I guess the only way you can resolve your problem without an actual navigation bar is to add a view under status bar and make it opaque just like your search bar. it's a bit hacky but it's alright in my book.
I have a navigation controller where I add a toolbar based on user input.
When the user hits back to the home screen. I don't want the toolbar.
self.navigationcontroller.toolbar.hidden = YES;
This just hides the toolbar and the UIImage on the homepage is now shifted up the 40px and the black background appears where the toolbar is hidden.
How can I REMOVE the toolbar so the image doesn't get pushed up.
self.navigationController.toolbar.hidden = YES;
needed to be replaced with...
self.navigationController.toolbarHidden = YES;
To keep the position of the child VC's frame move it with 40px down (animation with duration 0.25 f.e.), when you hide the toolbar, or change the navigation controllers bounds origin with origin.y+40, just like you would do, when you are hiding the status bar. But i think an empty space will remain, you should do something with it.
For swift you need to write:
self.navigationController?.isToolbarHidden = true
