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 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 UISearchDisplayController that goes black after erasing search-text.
These pictures explain my issue:
Add an a to the searchbar
Removes the a from the searchbar
I tried these settings in ViewDidLoad, but it's not working.
self.searchDisplayController.searchResultsTableView.backgroundColor = [UIColor clearColor];
self.searchDisplayController.searchResultsTableView.backgroundColor = [UIColor clearColor];
Actually the searchResultsTableView is not shown when the search bar is empty. Instead a semi transparent view is shown so that you can see the underlying view (usually the view of the VC that invokes the search). In your case I guess the underlying view is black so it doesn't matter that the search view is semi transparent :)
Setting its background to white color should do the trick.
I have two UITableViews in my app (one for regular usage and another for searching). When I use regular one the status bar is opaque but when I enter searchResultsTableView I can see some items from regular UITableView.
As you can see the UISearchBar is opaque so there is nothing behind it but status bar is still transculent.
I've already added [self.tableView setHidden:YES]; in searchDisplayController: willShowSearchResultsTableView: but it's a very primitive solution and does not work when my regular UITableView is displayed at the beginning of search.
My question is how to make status bar opaque? Just to avoid this annoying thing.
I've found two solutions to this issue. Both works for me but the second one is simpler and you don't have to do anything in code. I hope you find it useful!
First solution:
You can create a custom UIView in code and add as a subview. If your application has one color of UINavigationBar or any other component and it won't change through the lifecycle you can always implement this in application:didFinishLaunchingWithOption:. Otherwise, you can always add this code in proper moment but you have to remember to add this subview to proper super view. Here is the code sample:
UIView *addStatusBar = [[UIView alloc] init];
addStatusBar.frame = CGRectMake(0, 0, 320, 20);
addStatusBar.backgroundColor = [UIColor colorWithRed:0.79 green:0.79 blue:0.81 alpha:1];
[self.navigationController.view addSubview:addStatusBar];
Second solution:
There is one tiny checkbox in Xcode called Clip Subviews and it's super useful in that case. You can find the view which is visible under Status Bar (In my case it's UITableView) and clip it to subviews. I don't know how but in my case UISearchBar started affecting status bar so now it's opaque qith a color of UISearchBar.
Don't know why, my search bar in iOS 7 is leaving a right space. It's ok in iOS 6.
I know it has something to do with the section index, because if I remove it the space disappears, but I don't know how to fix it. Any thoughts?
Embed your UISearchBar in a UIView and then add that as the tableHeaderView. Structuring it that way in a storyboard worked for me. I'm guessing iOS resizes the UISearchBar in the tableHeaderView, but leaves a basic UIView alone (and doesn't bother to look inside it).
You might also want to make the section index transparent, which I did with:
[[UITableView appearance] setSectionIndexBackgroundColor:[UIColor clearColor]];
[[UITableView appearance] setSectionIndexTrackingBackgroundColor:[UIColor clearColor]];
Until a better answer appears, I just manually changed the frame of the search bar like this:
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
CGRect barFrame = self.searchBar.frame;
barFrame.size.width = self.view.bounds.size.width;
self.searchBar.frame = barFrame;
}
I had this same issue with the iPhone 6/ 6Plus when using a SearchDisplayController. (Using Swift)
I tried setting the frame of the search bar but with no luck but i noticed that if i tapped on the textField of the UISearchBar and then cancelled it then it would take on the proper size of the view. I therefore managed to fix the issue by calling the code below in ViewDidLoad of the viewController using the search.
self.searchController.setActive(true, animated: false)
self.searchController.setActive(false, animated: false)
self.contactsTableView.sectionIndexBackgroundColor = [UIColor clearColor];
The reason for that white edge is because your index layer has a white background and is on top of the search bar. This should be sufficient.
Add the search bar inside a UIView put as tableView's header view. Set the tableview's sectionIndexBackgroundColor to clear color because it covers the header.
Tested with iOS 7, 7.1;
Because the table view always leaves 15px on the right for section Indexes View, so you should resize the Seach bar after reloading the table view
First:
self.tblData.sectionIndexBackgroundColor = [UIColor clearColor]; //(iOS >= 7 only)
Cheating time:
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate
{
[self performSelector:#selector(resizeSearchBar) withObject:nil afterDelay:0.01];
}
- (void) resizeSearchBar
{
CGRect frame = self.searchBar.frame;
if (frame.size.width < self.tblData.frame.size.width) {
frame.size.width = self.tblData.frame.size.width;
}
self.searchBar.frame = frame;
}
- (void) reloadTableData // call it anytime you want to reload table view
{
[self.tblData reloadData];
[self performSelector:#selector(resizeSearchBar) withObject:nil afterDelay:0.01];
}
Suggest
Dont cheat like me, just do the simpler way:
self.searchBar.searchBarStyle = UISearchBarStyleMinimal; // iOS >= 7 only
I also attached a UISearcBar in my application, and nothing is wrong there even my application supports rotation also.
Could you try removing and re creating UISearchBar in storyboard/xib
I added the search bar as a subview of the top-level view instead of the table view. Used autolayout to pin the searchbar to the top guide, and a vertical space constraint of 0 between the search bar and the table view.
The accepted solution with the method viewDidLayoutSubviews makes the screen flicker.
Instead what I did was create a subclass of UISearchBar that simply does this:
FullWidthSearchBar.h:
#interface FullWidthSearchBar : UISearchBar
#end
FullWidthSearchBar.m:
#import "FullWidthSearchBar.h"
#implementation FullWidthSearchBar
- (void)setFrame:(CGRect)frame {
frame.size.width = self.superview.bounds.size.width;
[super setFrame:frame];
}
#end
And then I assigned that class to the search bar on my xib:
The problem is the right white block, so if we change the block color the same as the search bar background, it looks normal.
just
if (IOS7) {
self.tableview.backgroundColor = [UIColor colorWithPatternImage:self.searchBar.backgroundImage];
}
