Top-Fold Bug - Unable to scroll centerfold after top-fold

[jpcguy89]

I've been experimenting with the...err...experimental...top-fold, and thought I'd try and help out by reporting the bugs I run into. If I slide to to the topFoldView and return to the centerTableView, I cannot get it to re-enable scrolling in that view.

I've tried all of the various combinations of enabling and disabling the topFoldView and bottomFoldView, together with sending setScrollEnabled:YES to centerTableView with no luck.

Thanks. Knew I should wait first before merging into master :p

Hey i did notice the same bug today and tried to fix it in a very short way. Probably you can use some of it :)

In your RootViewController add the a class Variable and the following function:

float lastContentOffset;

-(void)scrollViewDidScroll:(UIScrollView *)scrollView{

    int scrollDirection;

    if (lastContentOffset > scrollView.contentOffset.y && scrollView.contentOffset.y <= 0) {
        [self.centerTableView setScrollEnabled:NO];
    }
    lastContentOffset = scrollView.contentOffset.y;
}

This will let you unfold you topFold when you are scrolling up.

Then in your PaperFoldView.m find the following function

- (void)animateWithContentOffset:(CGPoint)point panned:(BOOL)panned

and replace the last else compound with the following:

else
 {
     [self.contentView setTransform:CGAffineTransformMakeTranslation(0, 0)];
     [self.bottomFoldView unfoldWithParentOffset:y];
     [self.topFoldView unfoldWithParentOffset:y];
     self.state = PaperFoldStateDefault;

      if ([self.delegate respondsToSelector:@selector(paperFoldView:viewDidOffset:)])
      {
         [self.delegate paperFoldView:self viewDidOffset:CGPointMake(0,y)];
      }

       for (UIView *view in self.contentView.subviews) {
          if([view isKindOfClass:[UITableView class]]){
              [(UITableView*)view setScrollEnabled:YES];
           }
        }
 }

This will enabled the scrolling back when you close your topFold.

Hope this helps and is comprehensible ;)
