All of my tableviews throughout the app are exactly the same and i have no issues with them. Could it possible have to do with initializing the Controller from another viewController? I wouldn't think so. My cell in the storyboard has been given the identifier. Here is a link to a screen shot. So i have tried everything here and nothing has worked. Here is the output using the [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath

However, there doesn't seem to be any easy way to preserve the formatting of the cells; it always gets blown away and set to blank. Is there any simple way I can do this? Thanks! /YGA A sample script: from xlrd import open_workbook from xlutils.copy import copy rb = open_workbook('output_template.xls',formatting_info=True) rs = rb.sheet_by_index(0) wb = copy(rb) ws = wb.get_sheet(0) for i,cell in enumerate(rs.col(8)): if not i:

In the collectionView cellForItemAtIndexPath: method, it creates a series of custom cells based on the datasource. The custom cells in turn contain a UIView, subclassed to draw single PDF pages. It's set up in such a way as to split a PDF file into its single pages, so cell 1 contains PDF page 1, cell 2 contains PDF page 2 and so on. So far so good, here's my problem: When I scroll down, the UICollectionView starts displaying the wrong cells. For instance in a 34 page document,
