I'm trying to use the printing stuff in iOS 4.2 to print from my iPhone app, but I'm having real trouble getting multi-page content to display nicely. As you can see in the attached screenshots of PDFs generated through the iOS printing API, UIMarkupTextPrintFormatter really likes to use a painfully small top-margin when rendering.
Additionally, it doesn't seem to try to split block-elements too nicely either ... it's tough to see in the screenshot but the page break actually occurs halfway through a table row, rather than on a border between rows.
I've tried using the CSS #page directives to specify page boundaries, however iOS Webkit doesn't seem to support these at all.
Does anyone know of any techniques, either in HTML or through the iOS SDK to make these top-margins bigger?
I really don't want to write a custom UIPrintPageRenderer class because I'm trying to give my users the ability to customize their printouts through HTML templates ... going with a custom renderer would almost certainly make this impossible (or really difficult).
Any help is much appreciated!
You're on the right track with UIPrintPageRenderer, but fortunately you don't need to write a custom subclass to do this. All you need to do is instantiate a vanilla UIPrintPageRenderer, set the headerHeight and footerHeight properties, and add your HTML formatter to the renderer using addPrintFormatter:startingAtPage:. It only takes a few extra lines of code, I have posted my method here: Print paper size and content inset

I've been working on a website and from time to time some elements are disappearing from the document. I've figured out that it's because in CSS document the early lines are not fully commented. I would like to ask why if even such a tiny thing like Skeleton's default version text is not fully commented or some of the classes or id's don't have a closing bracket then the whole website has layout problems. What skeleton's version has to do with page's body color ? This is really confusing.
Here is the HTML and CSS :

Browsers have to guess how to render bad code. Sometimes they will guess and render it correctly, other times it will look weird.
Different browsers are likely to render it differently (though error handling standards are improving)
In this case, your demo lacks a "/" at the start, which means it is trying to render the comments as css. The comments are not css, so it gets confused and does the best it can.
A quick way to find any bugs in the css is to use this:

I'd like to create a twitter like stream out of a sap.m.list, hence when I get more data with a pulltorefresh control, I'd like to update the list with the additional rows, but should not move the list at all, and be hidden until the user scrolls the list down.
Any standard ways of doing this, or alternatively, custom CSS/JS recommended ways of doing this?
Thanks,
Matt
There's no need to drop down to jQuery here as OpenUI5 already contains the awesome iScroll library.
I've just setup a test app for you to have a look at here: https://github.com/js1972/ui5_pull_to_refresh.
Clone this; check the readme; then just run grunt serve to open the app in your default browser. You can use Chrome dev tools to emulate an iphone or android, etc.
I think this does what you're after - it works just like the GMail mobile app. You pull down to refresh items and at the end of the refresh your still looking at the same items but can now scroll up to see the new ones.
Will be interesting to see the performance if you have a thousand items... iScroll gives you allot of settings to play that may help (which aren't discussed in the UI5 SDK).
One thing to be careful of with browser scrolling is paint times. If the browser is not 100% done painting then iScroll can't calculate all the element dimensions it needs and you get strange results - typically just no scrolling. Sometimes you've just got to give a little time back to the browser by wrapping things in setTimeout(scroll_stuff, 0).
Hope this helps...
While not quite the answer I was after, looked into doing it another way, and provided you can work with automatically generated Id's that you'll need to calculate based on the row number, the following is one brute force way of doing it (I've borrowed it from another SO question and kept the animation for fun - Referenced SO Link):
var pOffset = $("#__item0-App--Main--MyList-76").position().top;
$("#App--Main--myPage-cont").animate({scrollTop: ( pOffset)}, 800);
The object is to Show-Hide text located under their respective Titles, so a User reads the title and shows or hides text belonging to that title if the User wants to read more.
I tried whatever I could find so far on here, we're talking dynamically setting text coming from a spreadsheet, can't use IDs, must work with .class, must be missing something, I have this piece of code:
... html.push('<div class="comments">' + comment + '</div></div></div>');
but when I try this Show-Hide code nothing happens, even if the error console shows nothing. Basically I want to Show-Hide the .comments class divs with a show-hide toggle link located under each of them. I say them because the .comments divs are reproduced dynamically while extracting text coming from Google spreadsheet cells/row (one .comments div per spreadsheet row). I tried .next, child and parent but they all divorced me so I dunno looks like a dynamic issue. So far I only managed to globally toggle all divs to a visible or hidden state but I need to toggle independantly individual divs.
I prefer a jQuery solution but whatever worked so far was achieved with native javascript.
Note: If a cross-browser truncate function which would append a more-less link after a number of words (var) in each .comments divs would be easier to implement then I would gladly take that option. Thx for any help, remember I am still learning lol!
I have been working on an entirely JS UI project and have brought myself to using $('', { properties }).appendTo(BaseElement) to work best for adding HTML elements because it appropriately manipulates the DOM every time.
If you are having good luck with push elsewhere, however, breakpointing on the line where you do your $('.class').hide() and see what $('.class').length is. Alternately, you can just add alert($('.class').length) to your code if you are unable to breakpoint the code. If it is 0, then your elements have not been properly added to the DOM. Changing to append will ensure they are part of the DOM and therefore targetable via JQuery.
I'm fairly new to Cocoa and am having trouble Googling for the best way to design my iPhone app.
This app is for viewing a stageplay. It should pretty print the script such that character headings are centered and in small caps, say, and stage directions are in italics etc. It should also allow one character's lines to be highlighted (i.e. dynamic formatting).
Looking at this question it looks like NSTextView/NSTextStorage will provide the formatting requirements I want, I'm just confused as to how to construct the view from the underlying data.
I'm thinking at the moment my source will be XML in the following form:
<script>
<dialogue character="bob">Hello Sue!</dialogue>
<stageDirection>He moves to the table</stageDirection>
<dialogue character="sue">Hello Bob!</dialogue>
</script>
Which would output something similar to the following:
BOB
Hello Sue!
He moves to the table
SUE
Hello Bob!
How do I go from a document model (XML / CoreData / ...) to a view containing pretty formatted text?
Any advice or pointers would be great; I just can't get my head around this problem!
If interactivity isn't required then the most easy way I can think of is to generate HTML and render it with UIWebView. Dynamic highlighting can be done with stringByEvaluatingJavaScriptFromString:
UPDATE
Next relatively easy option is to compose styled text with individual UILabels. Basically you have an array of text entries (cues, stage directions etc.), each with it's own style. We create an array of corresponding UILabels with styles applied and then layout them on "script view". After that we can put this "script view" in UIScrollView and that's it. Size of label required to fit particular text can be determined with sizeWithFont:constrainedToSize:lineBreakMode: of NSString.
There are also CoreText services available, but this is much more advanced option.
I'm looking for a tutorial without any javascript - pure CSS3.
I've created two pages (page1.html, page2.html) for the iPhone and I'm using CSS3 and the -webkit-properties.
To connect those sites I created a next- and a backbutton.
When tapping on the nextbutton page2.html is loaded, when tapping on the backbutton page1.html is loaded.
This is working so far.
I'd like to try using some more -webkit-properties to get the flip-effect like in this demo.
So, when clicking on my next-button page2.html should be flipped in. When clicking/tapping on the backbutton page1.html should be flipped in.
I'm new to this and hope to get some help here. Do you know a tutorial dealing with my problem?
Another question coming up to my mind was whether it is possible to load page2.html seperatly or whether I have to build only one page with the content of page1.html and page2.html?
You have to build only one page with two sections/divs with the flip-contents in it. Then you can use the transform: rotateY … or, maybe load the second page in with AXAJ or something else, but because it's CSS on my understanding you have to put everything in one page with two sections/divs
There are lots of pageflip demos on the interwebs. This is one we did It was inspired by Roman Cortes one - there are others that use more of a squeeze than a flip.
