How to scroll MXScrollView to top programmatically about mxparallaxheader HOT 6 OPEN

Max,
Hi and Thanks.
Another need / vote to enable programmatic scrolling.

from mxparallaxheader.

As a workaround I'm calling scrollView:setContentOffset: since it disables KVO in MXScrollView while you change it.

[self.scrollView scrollView:scrollView setContentOffset:CGPointMake(0, -self.scrollView.contentInset.top)];

Of course I had to expose it in a category.

@interface MXScrollView ()
- (void) scrollView:(UIScrollView*)scrollView setContentOffset:(CGPoint)offset;
@end

from mxparallaxheader.

Hi @andiradulescu
Yes the contentoffset is locked by KVO, I will try to find a fix.

Hi @maxep! Thanks!
I would've tried to find a fix myself (instead of the workaround), but I'm not sure what is the correct approach.

[self.scrollView scrollView:scrollView setContentOffset:CGPointMake(0, -self.scrollView.contentInset.top)];

Where did you put this code ?

Hi, I have forked this library into swift version called HPParallaxHeader: https://github.com/ngochiencse/HPParallaxHeader
If you need to perform tap on status bar to scroll to top, HPParallaxHeader automatically handle for you.
If you need to scroll to top programatically, I have created this method for you:

/**
     Scroll to top manually which show parallax header totally
*/
open func hpScrollsToTop(animated: Bool)
