I have a full screen UIScrollView to display my image. And the scroll view recognize long press gesture. After long pressing on the scrollview, an action sheet shows up. If i add the action sheet to the window, it will not rotate while I am rotating the screen. If i add it to the scroll view, it rotates but not that good when the scroll view has been zoomed or scrolled. Is it possible to rotate the action sheet well regardless of the scrolling and zooming of the scroll view?
ps. the scroll view is directly add to the window by "self.view = myScrollView;"
Adding the scrollView to the rootviewcontroller or the parent view on which scrollview resides would be better and solve you problem.

I am implementing a scroll view which consists of an image underneath it is a collection view.
What I want to do is a smooth scrolling between the page as if the collection view is just elements in the scroll view.
But what happens is the when I scroll, the collection view needs to be dragged twice to exit it or to enter it.
What I mean is that when the scroll view first appears there is an image and under it is collection view. when I scroll down if I touch the image, the scroll is done correctly, however, if I touch the view the image is still here and a small scroll is done then when I scroll again the scroll is done right and the collection view takes the whole screen
After that when I scroll upwards, the same happens a small scroll happens then I have to touch again to do the scroll right and show the image.
EDIT: This GIF shows would clarify what I mean :

Edit: The best solution was to create a TableView/CollectionView header and and my header in it and scroll normally for the table/collection view.
Old solution
The solution as provided in a comment by #MayurKarmur was to disable the scrolling in the collection view and adding height to collection view according to its content.
i am creating an app which has two UIImageViews at top and bottom of the screen and few customs buttons in between them which i am using in a UIScrollview so that user can scroll through them while the two images remain on top & bottom as they are.But when i use the scrollview the buttons scroll over the two UIimageview instead of just scrolling between them or hiding behind them as users scroll down..how can i make the UIImagviews remain on top of the buttons in UIScrollview??
I assume that you use the Interface Builder...
Make sure that:
The frame of the scroll view is between the image view
The Clip subviews of the scroll view is checked
The image views appear after the scroll view in the views hierarchy (if not then you can just drag them inside the hierarchy)
Is there better (framework built in) way to add small "touchable" round info button (i) on top of scroll view? Theoretically I think there should be container view for button(UIControl or UIImageView with png?) and scroll view.
Simply make your information button float above the scroll view by adding it to the scroll view's superview, then ordering the views such that the information button resides on top of the scroll view. You'll retain scrolling capability, while still catching button touches.
I have a view with half a dozen text fields and labels, and a button.
I want it to be that when the keyboard pops up, the view becomes scrollable, so you can scroll the view up and see the bottom half of the fields without having to dismiss the keyboard to get to them.
Just putting it inside a UIScrollView doesn't seem to do it.
You have to set the scroll view's contentSize to enable scrolling.
I have a UIButton within a UIView. The button is docked on the bottom of the view using the Autoresizing Masks. The button is working fine when the view initially loads and the IBAction is being called successfully.
Now when I resize the height of the parent view the button stays docked at the bottom of the view, however now only half of the button responds to the touch events. If I resize the parent view height a bit larger then the button completely doesn't respond anymore.
Any ideas why this would be occurring?
It sounds as if you've got another view, most likely a transparent one, that is resizing improperly and covering up part of the button.
It seems that I was moving the main view as the inner view height was changing. I guess if the UIButton is outside the bounds of the self.view then touches are not received.
