I have a tableview with view with search bar on top of the screen below navigation bar. There is also tab bar on this screen. When search controller is activated first, time search bar hides under navigation bar (Translucent set to NO).
In viewDidLoad, searchDisplayControllerDidEndSearch and searchDisplayControllerWillBeginSearch I am setting the search bar frame:
self.searchDisplayController.searchBar.frame=CGRectMake(0, 0, width, 44);
I am not using AutoLayout

In iOS 11, when the navigation bar is shown (after having been hidden), the entire view below it moves down. How can I stop this from happening?
Nav bar hidden:
Nav bar showing:
set the transparency of navigation to false.
self.navigationController?.navigationBar.isTranslucent = false;
I am implementing a ButtonBarPagerTabStripViewController with two buttons on my navigation controller's navigation bar. I followed the example provided by adding the following into viewDidLoad()
self.buttonBarView.backgroundColor = UIColor.clear
self.settings.style.buttonBarItemsShouldFillAvailableWidth = true
self.buttonBarView.removeFromSuperview()
self.navigationController?.navigationBar.addSubview(buttonBarView)
However when the Button Bar loads in the navigation bar the width of the Button Bar exceeds the width of the navigation bar. This leaves me with the following:
How can I fix this so that all the buttons fill the width of the navigation bar but do not exceed the width of the navigation bar?
Connecting the containerView outlet to a UIScrollView in Interface Builder fixed this problem for me.
In my UIViewController I have UIImageView that takes up the full size of the controller (screen) and serves as a background. On top of UIImageView I have a UITableView with a clear background. I set the navigation bar to translucent like this:
self.navigationController.navigationBar.translucent = YES;
UIImageView is underneath the navigation bar as I want it to be. Unfortunately the same happens to UITableView. I want to put UITableView at the bottom of navigation bar, leaving UIImageView underneath. If I set:
[self setEdgesForExtendedLayout:UIRectEdgeBottom]
then UITableView is at the bottom of the navigation bar, but the same happens also to UIImageView. What would be the easiest solution to leave UIImageView underneath the navigation bar and push down the UITableView at the bottom of the navigation bar?
By default in iOS 7 the content extends to the top and bottom of the screen, underneath any navigation bars, tool bars, or tab bars. If you were to set the frame of the table view to be start after the navigation bar, the content of the table view would not scroll beneath the navigation bar providing the nice blur effect.
What you'll probably want to do instead, is keep the y origin of your table view at 0, underneath the navigation bar, and set the content inset so the content starts after the navigation bar.
This is pretty simple. If you're using auto layout the top layout guide of the view controller will recognise the height of the status bar and navigation bar so you don't need to calculate this yourself. The bottom of the navigation bar should end at 66.
//Using Auto Layout
CGFloat navigationBarHeight = self.topLayoutGuide.length;
//Not using Auto Layout
UINavigationBar *nav = self.navigationController.navigationBar;
CGFloat navigationBarHeight = nav.frame.origin.y + nav.frame.size.height;
myTableView.contentInset = UIEdgeInsetsMake(navigationBarHeight, 0, 0, 0)
And of course if you actually do want the frame to start after the navigation bar the height above stays the same, you just need to manually set the frame of the table view.
CGRect tableViewFrame = self.view.bounds;
tableViewFrame.origin = CGPointMake(tableViewFrame.origin.x, navigationBarHeight);
tableViewFrame.size = CGSizeMake(tableViewFrame.size.width, tableViewFrame.size.height - navigationBarHeight*2);
myTableView.frame = tableViewFrame;
EDIT: Ah, almost forgot. You'll also want to change the scrollIndicatorInsets to match the contentInset, so your scroll bars don't move offscreen.
myTableView.scrollIndicatorInsets = myTableView.contentInset;
I have a ViewController with a navigation controller and a tab bar controller. This ViewController has 2 buttons that toggle the visibility of a scroll view and a map view. The main thing is to have these 2 buttons always show up in the same place regardless of orientation or the view that happens to be visible.
The problem I am having is that the MapView won't size properly. If I just give it a frame from self.view.bounds it goes under the navigation bar / tab bar - basically taking up the whole screen. This throws off the location of my toggle buttons.
I noticed my ScrollView does the same (using a background color and a translucent navigation bar) but the positioning of sub views on it stay within the visible area (between the navigation bar and the tab bar). So when I add my toggle buttons, they show in the correct place.
When I press the toggle buttons, I just re-assign the parent view of the buttons to the now displayed view (ScrollView or MapView). This always works on the scroll view but due to the positioning, they end up going under the navigation bar when the MapView is displayed.
I have tried creating the frame for the MapView manually but I get odd results. I use this for the frame:
CGRect mapFrame = CGRectMake(
0,
(self.navigationController.navigationBar.frame.size.height + [UIApplication sharedApplication].statusBarFrame.size.height),
self.view.frame.size.width,
(
self.view.frame.size.height
- (self.navigationController.navigationBar.frame.size.height + [UIApplication sharedApplication].statusBarFrame.size.height + self.tabBarController.tabBar.frame.size.height)
)
);
I then set the auto resizing masks
[self.mapView setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin];
But with this, if I enter into the view controller in landscape mode - the MapView is off the screen. If I enter in portrait mode and then rotate to landscape, the top margin is off but about 10 points so it still goes under the navigation bar a bit (and has a visible margin between the tab bar and the bottom of the map view).
How can I make the MapView subviews only display within the visible region like the ScrollView does? I don't mind so much if the map itself goes under the navigation bar / tab bar
Ugh, I found the answer just a few minutes ago. I have no idea why this is the default behavior on iOS 7 but alas, there it is.
The solution is to add this to the viewDidLoad on the ViewController
[self setEdgesForExtendedLayout:UIRectEdgeNone];
[self setAutomaticallyAdjustsScrollViewInsets:NO];
Much thanks to the post here
I have a tableView controller which has a searchbar added to tableHeaderView. When I click on searchBar it animates to cover the screen. However, the view behind gets adjusted and navigationBar overlaps with status bar as shown below:
It adjusts back fine, when the search is cancelled. How to hold the view at the back of searchDisplayController not to overlap the status bar?
fixed by doing: [[[parentFileViewController navigationController] navigationBar] setHidden: YES]; in searchDisplayControllerWillBeginSearch method where parentFileViewController contains the searchBar
