Ok, so I have an iPhone application that displays Word documents for certain terms and all. My problem is that the text seems to be "wrapped" or something else like that. This causes the words to not line up, which ultimately makes a lot of my Word documents contain incorrect information
I am inserting the .doc files into a UIWebView which is set for "scale pages to fit". Also, when I zoom in it still stays the same way. This is happening in both the simulator and the actual iPhone.
All help is appreciated!
Below are two screenshots. This first one is of the iPhone app:
This second one is of the Word document and how the text should really look:
Save the doc as an HTML and use the HTML in your app. That should resolve the issue.

This is perhaps a more general question as I'm looking for ideas on how to approach a problem working with PDFView/PDFKit. I have a small sample application that allows you to display a page, select a range of text and then associate a comment with that text. Once the comment is saved the comment is displayed on the PDFView page in the margin via an overridden draw() function for PDFView.
Problem is that with very small margins the comments can be very squished. I've been looking for a straight-forward solution and would very much appreciate ideas on how to address it.
The obvious (ie, easy) solution is to change the actual "page size" in the PDFView and have wider margins, but of course PDFKit has no support for that (I don't think). Another thought was to go to a custom PDFView library but the only ones I found when I last looked were iOS (not Cocoa) based.
Last idea was to instead of drawing directly on the page have some sort of pop-up window (like a sticky-note) contain the note but then it would need to be moved dynamically with the scrolling of the page. And of course one other was to recreate the PDF dynamically for viewing and make all the pages larger... but I've not dug into how much of a performance hit / effort that would entail.
Maybe there's a simple/obvious solution that I've missed?
I created a simple sample app in gitHub which shows the basic functionality for people to play with if that's of help. https://github.com/jcnolan/PDFMarginTextView
I have a Word-File in which I'm going to add content programmatically.
The content is going to be added into table-cells and thats where the problem starts:
The Word-File looks like this
The cell where it now says "000000873588" is the one being filled by my application. This is working fine until someone enters a string thats too large like so:
The text is being broken down onto the next line which leads to my document actually adding a second page at the end because the whole content doesn't fit anymore.
Now I know the easiest way would be to already truncate the string in the application itself, but this would require me to know the exact cell-size of each cell in the document, which I don't as I have 12 different document-templates that are all being filled programmatically.
Is Word able to set a table-cell to a fixed size and then just cut off the overflow? I can't really imagine it not being able to. I did quite some research but the only thing I found was keeping cells together over page-breaks which is not what I need.
I'm developing a book app.My client has provided all the contents of pdf.
I have already implemented all the contents of pdf to book.
But he wanted to highlight a text in that pdf.
The user would like the text to allow for highlighting (like if you're reading a paper book).
Is this possible? Can anyone help me on this, please?
Thanks in advance.
Theoretically yes.. depends on a bit hacking and other things, for example fonts used in the PDF. Have a look at PdfKitten, their demo project can find text in a PDF and highlight it. That should give you a first pointer on how to highlight. If you want to the user to highlight with the touches you would need to be able to transform locations of touches into the PDF to determine where exactly the user touched, but it should be possible.
I find some iphone book apps have such feature:
One screen one page of text without scrolling. The text can just fit into the whole screen with linebreaks and indentations.
I'm curious of how to implement this. How could I decide the length of text that just fit into the screen. And also, given the whole text, I can calculate out the number of pages.
If this is not possible to be done on iPhone(runtime?), then is it possible to process the text before storing it in app? I mean I calculate how many pages I need(how to split the raw text), probably how many lines per page.
I think this is what you are looking for
iPhone SDK: How do you measure the width and height of a string using Quartz?
The accepted answer gives methods you can call on NSString to calculate sizes
What I did for TouchTomes' books was have two iPhone apps. One was the reader that showed up on the App Store. The other was a renderer that calculated what could fit on each page, that only needed to be run in the simulator to create a book DB that the reader could use.
It would throw up a bunch of text, say 100 words, and see if that overflowed or underflowed. If it underflowed, more text was added (say 20 words) and it would binary search until it found exactly how much text would fit. Then it stored in a SQLite DB a row saying "page 12 shows words 100-228" for example. The app would go through this for each font. Another table held all the words in individual rows (!). An optimization step would chop that table down, combining words that always appeared on the same page no matter what font.
I used a Webkit display so the book could include HTML formatting. Now that really complicated the page breakup (e.g. had to keep italics going from page to page) but it let me include some fancier formatting in the text.
Then the reader app had very little to do to display pages; from the page id look up what range of words go on that page, then throw that text up into a webkit view. The user could jump between pages all over the book very quickly, all the hard CPU work had already been done by the rendering app.
I have about twenty UITextViews and corresponding .txt files. What I want is to make each UITextView take the contents of the corresponding file and display it.
Moreover, the text is formatted and it contains some formulas (copy/pasted from Grapher). I've heard about displaying formatted text in UIWebView, but I haven't found a clear explanation anywhere.
Thanks in advance!
Text files normally don't contain formatted text.
If by "formatted" you mean "html" then yes, you will want to use UIWebView. Basically you will convert the text to an HTML document, and then use the web view to display that document. There are several example projects available from Apple that show you how to use UIWebView.
Displaying formula in a UITextView will be difficult as the character rules for formula are completely different from language text. You could generate HTML to display it that but that is difficult as well.
I think your best bet would be to draw the formula to an image and then display the image. That is the traditional way to handle the display of formula.
