If you swipe when first loading the app without having navigated anywhere segfault

[thetrebor]

There is likely a much better solution:

///////////////////////////////////////////////////////////////////////////////////////////////////

• (void) loadBoundaryPagesIfNeeded { id item = nil;

  //stop everything from crashing if you try to swipe and you haven't navigated anywhere yet //RM--Fix if ([_pages count] <= 0) { return; }

  // calculate first visible page NSInteger firstVisiblePageIndex = [self indexOfFirstVisiblePage]; // get first visible page item = [_pages objectAtIndex: firstVisiblePageIndex];

  // load if needed if (item == [NSNull null]) { [self loadPageAtIndex: firstVisiblePageIndex]; }

  // calculate visible pages count and last visible page NSInteger visiblePagesCount = [self visiblePagesCount]; NSInteger lastVisiblePageIndex = MIN([_pages count]-1, firstVisiblePageIndex + visiblePagesCount);

  // check if first page is last page
  if (lastVisiblePageIndex != firstVisiblePageIndex) { // get last visible page item = [_pages objectAtIndex: lastVisiblePageIndex];

  // load if needed
  if (item == [NSNull null]) {
    [self loadPageAtIndex: lastVisiblePageIndex];
  }

  } }
