I have a TableView inside a ViewController.
I made the TableView stretch to the View SuperMargings (with constraints) and disabled all SafeArea Inset options but my TableView is still under the SafeArea when I run my project.
How can I make my TableView go full height on iPhones with notch?
If you have already pinned tableView to it's superview(not to safeArea) with constraints but tableView still respects safeArea there is property contentInsetAdjustmentBehavior in UIScrollView(UITableView is subclass of UIScrollView as we know) since iOS 11.
This property is UIScrollView.ContentInsetAdjustmentBehavior enum with 4 options.
You need to set .never to contentInsetAdjustmentBehavior.
What works with any view is to associate the bottom constraint of the table view to the bottom anchor of the root (or parent) view (instead of the SafeArea).
This can be done in the storyboard editor double clicking on the constraint in the right inspector and changing the first item anchor from SafeArea to Superview (or any wanted view).
You can then set the edge insets at will if needed (to avoid content remain partially hidden behind the rounded frame corners or the notch if applying the same procedure to the top anchor)

I'm trying to make a ScrollView so that its size adjusts to the size of the text. I placed all the necessary constraints
, but when the application is displayed on the simulator, the content view starts from the safe area and also ends up to the safe area. Although I have pinned scroll view to superview and content view to scroll view.
I want the content to start not from the safe area like here ,
but from the start of the screen like here
in other words, I want to remove the blue bar from the top and bottom
Do you have any ideas how to do it?
Sometimes UITableView & UIScrollView can still show safe area even though you attach your View to top of Super View. You just need to add one line to solve this issue but make sure your ScrollView is connected to superView not safe area at the top.
Add scrollView to your ViewController and in viewDidLoad() just write:
scrollView.ContentInsetAdjustmentBehavior = .never
Check this answer for further details: Make UITableView ignore Safe Area
Issue: gap above where contentView starts. Should be 0.
Despite setting the content view top bottom leading and trailing to 0, the content view has a gap at the top. I am using auto layout only.
Scrollview background is blue &
Content view is grey for easy viewing.
If I set the content view to equal heights as the scroll view, I get an error. And this doesn't seem like the right approach away. According to this setting equal height is optional:
Apple auto layout scrollview page
I do set equal widths.
Entire Screen:
Top of Scroll view:
Bottom of scroll view -> this is right - flush with bottom of scroll view (not sure if that matters)
Constraints:
Subview constraints:
Please help!! Also I am using xib files - not sure if that matters.
Thank you!
You'll notice that the gap is equal in height to the navigation bar.
The gap is there because by default iOS assumes that when using a translucent navigation bar, scroll views (and their subclasses like table views) begin at the top of the screen, behind the translucent navigation bar.
iOS then assumes you do not want your content hidden behind the translucent navigation bar, so it applies a top content inset to any scroll view, of height equal to the navigation bar height.
This behavior can be overridden in two ways:
Unmark Adjust Scroll View Insets on the view controller (see image below)
Make your navigation bar not translucent. If you're using a Storyboard, select the navigation controller that contains the affected view controller, and unmark the Translucent checkbox.
I'd like to resize my app components when device is turned into left or right side - when it keep horizontal position
I'm checking device rotation in willRotateToInterfaceOrientation event and then I have to change width of searchBar and tableView. How should I do it? I tried some variants with components .frame and with CGRect, nothing works.
Update:
it can be done without any code. View my answer below
If you laid out your elements in Interface Builder then you can just add an outlet to the width constraint of your search bar. Then, change the constraint's constant property to change the bar's width.
I found the way to do I need
So, the task is that components will be resized in width when device turns horizontally.
1) Select items must be resized
2) Select "Leading Space to SuperView"
3) Without unselection, select "Add missing Constraints"
That's it. Now they will be resized correctly
I have a UITextView that I want always to be 10px from the bottom of it's parent view (the scrollview). Problem is that I don't know how to tell the auto layout that it is supposed to do Bottom Space To: Parentview, instead of superview.
This is what I have now:
Update:
I need something similar to this:
I got that from here - http://www.techotopia.com/index.php/Working_with_iOS_6_Auto_Layout_Constraints_in_Interface_Builder - I want to have a UITextView in relation to the view it is in.
Click the gear for the “Bottom space to: superview” constraint and edit it. Set the constant to 10.
UPDATE
I've investigated this a bit and decided there's a bug in autolayout. Specifically, autolayout acts as if the size of the scroll view is 0⨉0 instead of its actual size.
Because of tis, if your text view has top-space-to-superview constraint and a bottom-space-to-superview constraint, only the top constraint will be honored. (I tried setting the priority of the top constraint to 1, the minimum, and the bottom constraint was still ignored.) If you delete the top constraint in viewDidLoad, the bottom constraint will be honored, but the text view will be laid out as if the scroll view's height is zero. This means that the text view's bottom edge will be 10 points above the top edge of the scroll view.
This happens in my testing with both a storyboard and a xib.
I have a vertically-scrolling UITextView that fills the width of the screen. I need the text view to have margins (contentInset) of 20 pixels on the left and the right. But for some reason, I can't get the right-hand margin to work, either in Interface Builder or in XCode.
The reason I can't just make the text view narrower is because I am adding a subview which needs to run the full width of the screen. Also, I can't turn subview clipping off, because it plays havoc with a load of other elements on the screen.
Anyone know why the contentInset property is not affecting the right margin?
Thanks!
You could add an intermediate view that can be the superview to your text view and what was previously it's subview.
New View with Frame(0,0,width,height)
->TextView with Frame(20,0,width-20,height)
->Subview with Frame(0,0,width,height)
