Currently, I have an RSS Feed Reader in a UITableView within a Navigation Control. I would like to click on the links and Open up a formatted page (containing all of the information from the website formatted for the iOS screen). I'm not sure if I should do this using the RSS data and a UITextView? I'm currently attempting to use UITextView in hopes that I can separate the information (title, author, body) without anything looking promising. I want to be able to move around the data and format it to my liking in the actual application itself. I read around and noted that you can include HTML and custom CSS. Would this be the way to go? I'm not quite sure how to tackle this. I want the page that opens up to be entirely scrollable (Like the IGN application or Slashgear application). Many apps for websites utilize this (and I am a bit new to this). How do they go about this? I also want to note, at some point I will like to cache the data so it may load what is already loaded without being connected to the internet. Does anyone have any ideas?
Edit:
Ok, I believe I found the correct path to go down from playing around and a lot of googling (nothing directly says what a decent way of doing this is). My particular way as of now is the route of a UIScrollView in general. Now the part I don't understand is how to divide up the long text into 'pages' for scrolling (and I am using the paging feature. This situation has led me into this question: How To Separate Strings For UIScrollView/UITextView based on the size of the frame

Ok so this question is actually in two parts.
I coded a video filter for VLC and I would like to add a control to the Video Effects panel on the OS X UI. So far I've been able to link my plugin the the UI by hijacking one of the existing controls, but this isn't ideal.
Now, if I open up the Xcode project (I'm running Xcode 6.3.1) and try to open the VideoEffect.xib file, I get the following error:
I tried to google this but it sounds like the only alternative would be to play archaeologist and dig up an old copy of Xcode 3. Is there any other way to be able to open this file and edit it somehow? I tried to look at the XML code but if I started to change that I'd do more damage than good.
The second thing I'd like to do is sending back values from the effect module to the UI. At the moment (by hijacking one of the existing sliders), all I can do is read a value from the panel with
config_ChainParse(p_filter, FILTER_PREFIX, ppsz_filter_options, p_filter->p_cfg);
p_filter->p_sys->i_factor = var_CreateGetIntegerCommand(p_filter, FILTER_PREFIX "factor");
and then, inside the callback function:
p_sys->i_factor = VLC_CLIP( newval.i_int, 0, 255 );
However, I haven't been able to write back the value. I'd like the filter to set p_sys->i_factor to a random value at start. This works (using var_SetInteger()), but it isn't reflected in the position of the slider in the Video Effect panel. I suspect I need to hack a bit deeper for that. Any ideas?
Regarding your first question with the xib-file. Consider downloading and using our forthcoming 3.0 code from git://git.videolan.org/vlc.git - it allows editing of said file without Xcode 3.
Regarding your second question, why would you want your video filter to interfere with the UI? This is not how the architecture of VLC works and there is no correct way to do it at this point. You would need to edit the core to do another global variable callback to ask the UI to reload the presented filter configuration.
Perhaps, if you give details about what your filter does and what you want to achieve, we find a more supported way :)
Im struggling with a thought here. Let's say a user has his own CMS where he can fill the content for our app. One of his options is to create a view by uploading images and typing text. Well keep it very simple and imagine he only uploads a image (320 x 20) and some text. So an image on top and some textlines below.
What would be the best way to let my app know of this layout and download the contents? I was thinking of a downloadable XML file which defines the layout but don't really know how to implement this or if its even the best way.
Oh and the content and layout must be downloadable for offline use too.
Another option what I was thinking of is showing the layout in a webview but I can't figure out how to download the mobile website for offline use.
A push in the right direction would be appreciated!
We use a custom XML and it is working good. All texts inside 'label tags' are in XHTML
remember to:
be specific when defining the xml to save some effort
write a limiting XSD! So nothing 'surprising' creeps into the xml
remember not include everything in ONE xml file as that would get rather large rather quickly. Choose a scheme for portioning the XML
I am trying to build a site using video.js to view videos. We need to switch videos while maintaining the currentTime value from the old video. The way I have it working right now is using the loadedmetadata event to set currentTime. The problem I am seeing with this is that the first frame of the video gets shown momentarily while the player seeks to the right time. I am new to JS programming so perhaps I am doing something wrong but I do not see anything in the docs that can help me overcome this. I am trying to render H.264/mp4 videos in Chrome. Thanks!
Changing the preload setting to 'metadata' might help this in the browsers that support that setting.
preload="metadata"
Then it supposedly should only load the metadata and trigger the loadedmetadata event, and not show the first frame. That is unless providing any new src forces preloading, and I'm not sure off the top of my head.
HTML5 video doesn't give us a lot of options around seamless switching videos unfortunately. The media source API proposal from Google/Microsoft/Netflix aims to fix this. http://dvcs.w3.org/hg/html-media/raw-file/tip/media-source/media-source.html
You could try this:
https://bitbucket.org/felixschwarz/videojs-hdtoggle/
As seen here on the old videoJS-Forum I think you might have to declare preload="auto".
In the linked forum-threat there are also some changes I made documented.
I've been programming for a while, but just recently decided to start developing for Mac OS X. I feel like I've come to grips with the basics of Objective-C and Cocoa development over the past week. I'm planning on making graphics apps, and as such am currently in the process of learning how to control Quartz compositions through a Cocoa app. I went through the tutorial that apple offers (with the Mac Engravings composition), and was able to create that just fine. In order to make sure that I truly understood what I learned, I decided to create my own composition and link it to a slightly more complicated Cocoa application.
Essentially, I have a composition that loads a movie or image through a Movie Loader patch, at which point it applies various filters to the frames before outputting it. In my Cocoa app, I've written code (or rather copied and pasted from other apple examples) that lets a user pick a file using an NSOpenPanel object. The filepath of the file they pick gets placed in a text-box that I placed in the app's window using Interface Builder. I binded the value of said text-box to the "Movie_Location" key in my composition, which is a published input in the Movie Loader patch that I'm using. However, no matter what I do, movies and images aren't loaded into this composition no matter what I try. The only thing that gets displayed is the default image that I have saved in that input from Quartz Composer (or nothing if I leave it blank before publishing).
I've added a Clear Color patch to the composition and binded that to a colorwell in my UI, and that successfully changes the color in my display, so I know that the composition and my Cocoa app are communicating. I've spent numerous hours at this point trying to figure out what's going on, and I've just about given up. Does the Movie Loader have any weird behaviors that I'm not aware of, or is there something obvious that I seem to be missing? I'd really appreciate any help or advice from anybody.
Thanks for reading through this...

There are two things I can think of as reasons why it is doing this:
The file path isn't formatted incorrectly. Try checking backslashes, colons, etc.
The box isn't updating the value. Try literally clicking in the text field and hitting enter.
That's all I can think of without seeing your quartz composition and/or code.
EDIT:
Check the other continuous box, in the general properties.
I figured this out yesterday. spudwaffle's second idea is what was going on. If I were to type a filepath in and hit enter, it would work just fine. I got this to work properly by just removing the bind and instead using the setValue:keyInPath: function that a patch controller offers. That said, is there some way to force a text-box to update? I remember seeing a "continuously update" or something like that button within the bind sub-menu in the inspector, but my code didn't work with that checked either.
Thanks to those of you that tried to help me! I really appreciate it.
Best,
Sami
I am developing an iPhone application where i want to display three image in each row on scroll view where i need to click action on each image like Photo album in iPhone. I am not getting any sample code.
Hoping for help

There's plenty of sample code out there, I found this after only basic googling. You want to search for "UIImageView Iphone". It's also worth mentioning that Apple's very own Developer Center is extremely well written, and will teach you everything you need to know about iPhone programming.
Generally it is frowned down upon to say to look more or read documentation, but you really haven't looked at all. Especially because of Apple's own resource that tells you how to do almost anything, especially something like this. It's not something you can pick up and bits and pieces of and expect to be successful with, it really should be learned starting from the beginning and moving forward. This is especially true if you've never programmed before or are unfamiliar with C/Objective-C.
Three20 has a photo browser that is open source and works similarly to the iPhone's photo browser with some nice code examples. The images come from an image source object that can relate them to images in your apps bundle or images on the web. Looks like its Google group is here. I think that to use images in your bundle you use a URL formed like: bundle://image-name.png and not the typical use of the main bundle to get a path to resource.
