I'm trying to speed up my UIScrollView and one method I know of is to set everything to be opaque. I think I have done so, to my UIScrollView, its contentView, the contentView's tiledLayer (I have a CATiledLayer as the actual useful bit that the users see), and on the UIView that all of this sits in. But despite all of that when I look i...

I have multiple editable textfiels and some of them are covered with keyboard. So I used UIScrollView and it works quite nice. Problem is when I want to hide keyboard.

I have a view that displays a PDF. It should be zoomable, so I also created a UIScrollView, and in its delegate I implemented viewForZoomingInScrollView to return the PDF view. So far so good. However, when the user reaches the edge of a zoomed PDF page, I'd like to flip to the next page. Sounds easy, yet I can't seem to figure out how ...
Hi I am loading in images with varying sizes and putting them in UIScrollViews, all the images are larger than the UIScrollView. The user can scroll and zoom as they please, but initially I would like for the image to be centered and scaled so the largest side of the image aligns with the edge of the scrollView, i.e. if the picture is i...

I tried catching it ...
Hey. I'm trying to use a UIWebView for displaying content higher than the screen of the iPhone, without needing to scroll in the webView itself. The webView is placed under a UIScrollView in IB with some other objects that I want the scrollView to scroll up and down with the UIWebView. I know you can do this with a UITextView (CGRect ...

For that, I need a way to get the total document size, including the scrollable ...
I have a CATiledLayer that is used to display a PDF page (this CATiledLayer is the layer type of my UIView which is a subview of a UIScrollView). I want to add overlay markers on this page. So I add a sublayer to my CATiledLayer. This sublayer again hosts the different marker's layers and acts as a grouping layer. So graphically, I have...
In my app, I have a table view. When the user clicks a button, a UIView overlays part of that table view. It's essentially a partial modal. That table view is intentionally still scrollable while that modal is active. To allow the user to scroll to the bottom of the table view, I change the contentInset and scrollIndicatorInsets values t...

Alright, so the key here is I'm not using IB at all, because the View I'm working with is created programmatically. The UIView covers the lower half the screen, and has a bunch of buttons on it. However, I want to add more buttons to the UIView, without making it any larger. To do so, I want to make a UIScrollView inside the view, whi...
