I have added the UISearchDisplayController via Interface Builder, and then I add the UISearchBar to my navigationBar like this
self.searchDisplayController.displaysSearchBarInNavigationBar = YES;
It works and looks fine. What I then want to do is add a subview to the searchBar (to act as a placeholder image). I do it by
[self.searchDisplayController.searchBar addSubview:self.imageView];
The problem is, the imageView is not visible. I NSLog its superview and I get a confirmation that it's the searchBar. I can also see that the searchBar has 1 subview, but when I log the subview, it tells me that it's... drum-rolls... the searchBar itself.
How can this be?
EDIT
Interestingly, if I add the searchBar to navigationBar as a subview and the add my imageView, it's visible. The problem is only when the searchBar is being added to navigationBar by self.searchDisplayController.displaysSearchBarInNavigationBar = YES.
Here's how I solved it - I hope this helps someone. The strange thing about adding a searchBar to navigationBar like this
self.searchDisplayController.displaysSearchBarInNavigationBar = YES;
is that the 'didLayoutSubviews' is called twice in the viewController, i.e. the searchDisplayController adds the searchBar to the navigationBar with a delay that I was not able to capture through existing delegate methods.
What I ended up doing instead is setting the zIndex of my imageView to maximum
self.imageView.layer.zPosition = MAXFLOAT;
so even if the searchDisplayController adds the searchBar to the navigationBar with a delay, the imageView still stays on top.

I have a UITextView inside a UIViewController that uses auto layout to pin it to 0 on all sides (so it fills the whole screen). I also have this view being pushed using UINavigationController.
I'm running into a weird error where if the UITextView has enough text so that it runs off the screen, then content gets set under the UINavigationBar. If there is not enough text to fill the screen the layout of the text doesn't go under the UINavigationBar.
Here is what's happening, this is when there is enough text that it goes off the screen and you need to scroll to view all of it.
I've tried:
Setting the content inset of the UITextView.
Made sure the UINavigationBar isn't translucent.
Tried setting this self.automaticallyAdjustsScrollViewInsets = NO;
Inside viewDidLoad of viewController where your textView is, add this:
self.edgesForExtendedLayout = UIRectEdgeNone;
I'm not sure why the problem was occurring but this fixed it:
- (void)viewDidLayoutSubviews {
if (self.textView) {
[self.textView scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:NO];
}
}
I view imbedded in a Navigation Controller which is slightly transparent. This view contains a UIscrollview. This UIScrollview has the following subviews: UIImageView, UILabel, and UIWebview. All these other views are working correctly. When the view loads, everything is in the correct position (The views are below the Navigation Bar). However, as soon as the screen is tapped, the scrollview repositions itself to the top of the view (aka behind the Navigation Bar, which is at the top, and I can see that this is true because the Nav Bar is slightly transparent)
Any idea why this is happening? I set up the scrollview like this:
self.scrollView.frame = CGRectMake(0, self.navigationController.navigationBar.frame.size.height, self.view.window.frame.size.width, self.view.window.frame.size.height);
Also set these properties:
self.scrollView.scrollEnabled = YES;
self.scrollView.alwaysBounceVertical = YES;
self.scrollView.bounces = YES;
Anybody know why this is happening?
I'd similar problem, but only on iOS 7.0. Try to set the translucent = NO property of the navigationBar. This will make the navigationBar opaque. Although if you want the navigationBar to be transparent, try to change the contentInset of the scrollView to adjust the content as you want. Hope that this will help :)
I have a weird requirement, or at least something I have never done before... I have a UITableView, the header of that table is a UISearchBar. If you tap on that searchbar the "Search Display Controller" shows up and let you search... But now I need to remove that searchbar and call the "Search Display Controller" from a button.
The problem is that if I remove the SearchBar when I call (from the button):
[self.searchDisplayController setActive:YES animated:YES]
I can't see the UISearchBar on top of the View.
I have no idea how to fix this... I have already tried:
self.tableView.tableHeaderView = nil in the viewDidLoad and when touching the button I set the UISearchBar as the table header again... it looks ugly and the animation is not smooth at all.
hide the searchbar and show it when the button is pressed. (i get an empty space in the tableview's header) and the animation is really bad, because the UISearchBar gets first displayed in the header and the it's moved up to the top of the view...
Any help will be more than welcome!!
Thanks!
I realise that you have tried that, but thats the way we do it and it works:
We add the UISearchBar into the view (not the table view). That being said you can't do that if you are using a UITableViewController. You have to add the tableView to a UIViewController. Then we link it via an Outlet to the Controller and then set it to hidden in viewDidLoad:
self.searchBar.hidden = YES;
Then create a selector to show the searchBar again:
- (IBAction)search:(id)sender
{
self.searchBar.hidden = NO;
[self.searchBar becomeFirstResponder];
[self.searchDisplayController setActive:YES animated:YES];
}
Hope that helps.
I have a view which has two containers: Top_Container and Bottom_Container.
Each Container points to a VC with a TableView.
The Bottom_Container points to a TableView with a searchBar on top.
Whenever the searchBar gets activated in the TableView a white space appears below the searchBar between the searchBar and the greyed zone corresponding to the serachBarTableView (which superposes the TableView).
I have been trying with no success to get rid of this white space with no success.
Anybody has an idea how to customize:
- the white space which appears below the searchBar ?
- the greyed zone (searchBar TableView ?) on top of the TableView which appears whenever the searchBar gets active ?
Thank you.
Try with following code:
CGRect rect = self.searchBar.frame;
UIView *lineView = [[UIView alloc]initWithFrame:CGRectMake(0, rect.size.height-2,rect.size.width, 2)];
lineView.backgroundColor = [UIColor clearColor];
[self.searchBar addSubview:lineView];
It is fix.
I had similar problem and in my case it was caused by opaque NavigationBar. When I set NavigationBar to translucent, then the underlaying UITableView is correctly aligned to the active UISearchBar. (note: I'm using UISearchDisplayController in my view controller)
In your case maybe you can move (and animate) the underlaying table view in UISearchDisplayDelegate's methods willBeginSearch and willEndSearch. If you are using UISearchBar only, then you need to subclass it and override becomeFirstResponder and resignFirstResponder methods and implement the "table view moving" code there.
I just fixed this problem in my own code. For me, the issue was caused by 2 lines of code.
self.viewController.edgesForExtendedLayout = UIRectEdgeNone;
self.navigationBar.translucent = NO;
After removing both these lines, everything worked as expected.
I have a problem, I created a zoomable UIImageView with a UIScrollview, everything works perfect, exept the UIImageView is not in the center anymore and every time I hide the Tool- and NavigationBar the UIImageView/UIScrollView is moving up.
I already set the autoresizingMask:
scrollView.autoresizingMask = UIViewAutoresizingFlexibleTopMargin;
scrollView.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin;
but it won't work, can someone please help me?
I had the same problem with iOS 7, and read I had to set
self.automaticallyAdjustsScrollViewInsets = NO;
for the view controller, but it did not work for me. After I have released I had to put it in viewDidLoad method of the parent view controller of the view controller.
Just like #Mert answered, you can either set it in code self.automaticallyAdjustsScrollViewInsets = NO; or you can set this in storyboard, in the scroll view in one of the inspectors you can un-check the checkbox that automatically adjusts the scroll view content.
EDIT
The checkbox is in the attributes inspector of the UIScrollView, it's called Autoresize Subviews under drawing section.
Btw, this behaviour only happens in iOs7, because of the transparent UINavigationBar thing.
