I have an interesting embedded view issue in lotus notes. I have the view embedded into a table cell and have turned off scrolling and extend last column options and the scroll bars don't display, everything looks good.
But as soon as I check the display actions option the horizontal scroll bar scows. I only have one button. Is there anything I can do to hide the scroll bar?
You can show or hide only both the scrollbars at once. Impossible to set a property for only one scrollbar.

I want to make the search bar disappear by clicking the navigation bar item and make the collection view to fill the blank, animated obviously. ( like making the screen move upwards because the keyboard is showing )
is it Possible also to make it disappear when I scroll down an appear when I scroll up again ?
I dont think both ways will work at the same time but anyway I want to know how to make each way work.
thanks for the help :)
A collection view is a scroll view. A scroll view can have a delegate. A scroll view's delegate is told when the scroll view is scrolling. Therefore you can do anything you like in response to the user scrolling the scroll view, including moving the search bar.
I have an app which uses EMPageViewController to display a set of onboarding slides. My understanding is that the underlying scroll view is using paged mode to display slides.
Upon update to iOS11, I see that suddenly the slides follow the finger, so they are draggable and bounce up and down. I expect paged scroll view to be scrollable horizontally only.
How can I restrict paged scroll view to horizontal scrolling only in iOS11 ?
I tried this but it did not work
pageViewController.scrollView.alwaysBounceVertical = false
This fixes the issue:
if #available(iOS 11.0, *)
{
self.scrollView.contentInsetAdjustmentBehavior = .never
}
The behavior for determining the adjusted content offsets. This
property specifies how the safe area insets are used to modify the
content area of the scroll view.
contentInsetAdjustmentBehavior is new from iOS 11 > and the default value is automatic.
Content is always adjusted vertically when the scroll view is the
content view of a view controller that is currently displayed by a
navigation or tab bar controller. If the scroll view is horizontally
scrollable, the horizontal content offset is also adjusted when there
are nonzero safe area insets.
Which made some of my UIScrollView scroll more than they were excepted to.
I built my project as a Tab Bar Application that utilizes the UITabBarController.
I've set all the auto layout constraints for all my subviews and it looks right in the preview. When my application first starts, I hide the tab bar in viewDidLoad. Once a button is clicked, I hide the view and show the tab bar.
My problem is that the constraints adjusted themselves to the hidden tool bar and everything shifts down the length of the height of the tab bar. If I go to the second tab and back to the first, the constraints are back to normal. Is there an easy way to deal with this? I need to find out how to either hide the tab bar in other way that doesn't compromise my constraints, or how to allow the first view to extend down over the tab bar. Please help.
Hiding tab bar liks so.
[self.tabBarController.tabBar setHidden:YES];
Oddly enough. When I go to set the vertical constraint to the bottom of the view, the distance to the bottom of the view is equal to the top of the tab bar even though the height of the tab bar is 50 px.
This is not my day. I've just deleted every object from my previously completed view controller to start over because I can't get a simple scroll view to scroll. I've got a view controller that is embedded in a navigation controller. I put scroll view inside the view controller and then put two text fields inside the scroll view, one field at the top and one at the bottom.
First of all, when I run this, it won't scroll. What is the point of the scroll view if it won't scroll?
Second, I can't figure out how the relationship between the navigation bar and the scroll view works. Is the scroll view behind the navigation bar? Is it below the navigation bar? In the story board, it looks like it is behind the bar, but when I run it, my text field is pushed down so far that it looks like it is behind it.
Here are a couple of screen shots. To say that I am frustrated is an understatement. Thanks for any help getting me out of my circular problem. I appreciate it.
And here is how it looks when I run it. Notice how far down the top text field gets drawn. Also note that you cannot see the bottom text field. I am unable to scroll to this. What gives?

Scroll views won't scroll by default unless their contentSize exceeds their bounds. You can force it to scroll anyway by setting alwaysBounceVertical to YES.

Yes, in iOS 7, by default, a scroll view will start at y = 0, behind the nav bar. You use the contentInsets property to push it down. The view controller has an automaticallyAdjustsScrollViewInsets property that can handle this for you.
I would like to have buttons inside a scroll view (or another solution to creating a scrollable button bar).
I have buttons placed side by side in a row along the top of a view. As a user resizes the window to be less wide, fewer buttons can be seen.
When all the buttons cannot be viewed, I would like the user to still be able to access all the buttons by scrolling horizontally through them.
To visualise this, imagine in Safari if you open too many tabs to fit in the window - I would like the user to be able to scroll to the right and reveal the tabs that weren't on the screen.
You need to deselect the springs (for the custom view of the scroller) in the autosizing setter so that the view doesn't shrink along with the scroll view when you resize.
