Vfr-Reader UIScrollView from left to right - uiscrollview

Question

I'm using the Vfr-Reader source code and here I'm not able to scroll the scrollview from left to right, and by default it is from right to left. How can I achieve this I tried many just setting the offset and also tried putting the condition with the origin.
- (void)showDocumentPage:(NSInteger)page
{
if (page != currentPage) // Only if different
{
NSInteger minValue; NSInteger maxValue;
NSInteger maxPage = [document.pageCount integerValue];
NSInteger minPage = 1;
if ((page < minPage) || (page > maxPage)) return;
if (maxPage <= PAGING_VIEWS) // Few pages
{
minValue = minPage;
maxValue = maxPage;
}
else // Handle more pages
{
minValue = (page - 1);
maxValue = (page + 1);
if (minValue < minPage)
{minValue++; maxValue++;}
else
if (maxValue > maxPage)
{minValue--; maxValue--;}
}
NSMutableIndexSet *newPageSet = [NSMutableIndexSet new];
NSMutableDictionary *unusedViews = [contentViews mutableCopy];
CGRect viewRect = CGRectZero; viewRect.size = theScrollView.bounds.size;
for (NSInteger number = minValue; number <= maxValue; number++)
{
NSNumber *key = [NSNumber numberWithInteger:number]; // # key
ReaderContentView *contentView = [contentViews objectForKey:key];
if (contentView == nil) // Create a brand new document content view
{
NSURL *fileURL = document.fileURL; NSString *phrase = document.password; // Document properties
contentView = [[ReaderContentView alloc] initWithFrame:viewRect fileURL:fileURL page:number password:phrase];
[theScrollView addSubview:contentView]; [contentViews setObject:contentView forKey:key];
contentView.message = self; [newPageSet addIndex:number];
}
else // Reposition the existing content view
{
contentView.frame = viewRect; [contentView zoomReset];
[unusedViews removeObjectForKey:key];
}
viewRect.origin.x += viewRect.size.width;
}
[unusedViews enumerateKeysAndObjectsUsingBlock: // Remove unused views
^(id key, id object, BOOL *stop)
{
[contentViews removeObjectForKey:key];
ReaderContentView *contentView = object;
[contentView removeFromSuperview];
}
];
unusedViews = nil; // Release unused views
CGFloat viewWidthX1 = viewRect.size.width;
CGFloat viewWidthX2 = (viewWidthX1 * 2.0f);
CGPoint contentOffset = CGPointZero;
if (maxPage >= PAGING_VIEWS)
{
if (page == maxPage)
contentOffset.x = viewWidthX2;
else
if (page != minPage)
contentOffset.x = viewWidthX1;
}
else
if (page == (PAGING_VIEWS - 1))
contentOffset.x = viewWidthX1;
if (CGPointEqualToPoint(theScrollView.contentOffset, contentOffset) == false)
{
theScrollView.contentOffset = contentOffset; // Update content offset
}
if ([document.pageNumber integerValue] != page) // Only if different
{
document.pageNumber = [NSNumber numberWithInteger:page]; // Update page number
}
NSURL *fileURL = document.fileURL; NSString *phrase = document.password; NSString *guid = document.guid;
if ([newPageSet containsIndex:page] == YES) // Preview visible page first
{
NSNumber *key = [NSNumber numberWithInteger:page]; // # key
ReaderContentView *targetView = [contentViews objectForKey:key];
[targetView showPageThumb:fileURL page:page password:phrase guid:guid];
[newPageSet removeIndex:page]; // Remove visible page from set
}
[newPageSet enumerateIndexesWithOptions:NSEnumerationReverse usingBlock: // Show previews
^(NSUInteger number, BOOL *stop)
{
NSNumber *key = [NSNumber numberWithInteger:number]; // # key
ReaderContentView *targetView = [contentViews objectForKey:key];
[targetView showPageThumb:fileURL page:number password:phrase guid:guid];
}
];
newPageSet = nil; // Release new page set
[mainPagebar updatePagebar]; // Update the pagebar display
[self updateToolbarBookmarkIcon]; // Update bookmark
currentPage = page; // Track current page number
}
}
I changed this
if (maxPage <= PAGING_VIEWS) // Few pages
{
minValue = minPage;
maxValue = maxPage;
}
else // Handle more pages
{
minValue = (page - 1);
maxValue = (page + 1);
if (minValue < minPage)
{minValue++; maxValue++;}
else
if (maxValue > maxPage)
{minValue--; maxValue--;}
}
</pre>
I got the correct minValue and max value to load the left page and right page once you are on the current page, for example if I'm on the 3 page, then on the left side it should be 4 and right side should be 2 but it's not loading these instead it loads left side 2 and right side 5. Something that I'm missing can anyone help me out.
