Questions tagged [uiscrollview]

Use this tag for all questions about scroll views on iOS. Do NOT use this tag for other platforms.

UIScrollView is the native scroll view system in iOS. It is part of Cocoa and UIKit. A number of other very common iOS classes, such as UITableView, are based on UIScrollView. UIScrollViewDelegate is the associated delegate.

Full Apple documentation for UIScrollView is at the usual Apple documentation site. It is on the internet. It can be found at https://developer.apple.com/reference/uikit/uiscrollview.

Use this tag only for the specific, iOS, UIScrollView class. For the native scroll views in other specific platforms, such as Android, use those tags.

If you genuinely have a rare, non-platform-specific, general conceptual question about scroll views, you could use the otherwise totally worthless tag.

How to automatically size UIScrollView to fit the content

Is there a way to make a UIScrollView auto-adjust to the height (or width) of the content it's scrolling? Something like: [scrollView setContentSize:(CGSizeMake(320, content.height))];

Getting the current page

In my scroll view, I want to get the current page that's being displayed (maybe page isn't the correct term). I can't find any variable that holds this. But I think it must be held somewhere, since the indicator is able to show which sub-view of the…

UIScrollView pauses NSTimer until scrolling finishes

While a UIScrollView (or a derived class thereof) is scrolling, it seems like all the NSTimers that are running get paused until the scroll is finished. Is there a way to get around this? Threads? A priority setting? Anything?
