How to center content in a UIScrollView with contentOffset
I think you want:
CGFloat newContentOffsetX = (self.contentSize.width/2) - (self.bounds.size.width/2);diagram:
|------------------------self.contentSize.width------------------------| |-----self.width-----||-------- offset --------| ^ center
Use below code:
CGFloat newContentOffsetX = (scrollView.contentSize.width - scrollView.frame.size.width) / 2;scrollView.contentOffset = CGPointMake(newContentOffsetX, 0);
Swift 4
Scroll to center of content of ScrollView
let centerOffsetX = (scrollView.contentSize.width - scrollView.frame.size.width) / 2let centerOffsetY = (scrollView.contentSize.height - scrollView.frame.size.height) / 2let centerPoint = CGPoint(x: centerOffsetX, y: centerOffsetY)scrollView.setContentOffset(centerPoint, animated: true)
