I have seen some tutorials on the subject, but they all go half into it and then leave a person wondering.
How can I stream an rss feed into an iphone app.
I know the xml should be read in, parsed etc.
But then I am not sure how to display the information I need like, images, embedded videos etc.
If someone could just point me in the right direction I would be extremely grateful.
Thanks in advance
First, you need some type of XML parser. You can use the built in NSXMLParser or a slew of other parsers that you will need to download. Each have their pros/cons depending on what type of reading/writing you will be doing with your RSS feed.
To display the data, I would recommend a tableView. You can create custom UITablvewCells for each cell to hold the data however you want to display it. There are several tutorials available for that if you want to Google for it.
As for data, read all the RSS data into an array you create and have the tableView access that array.
Again, there are many online tutorials for this already but it seems like you need help with displaying the data. A quick Google lookup for how to create custom UITableViewCells should provide you lots of helpful links. Good luck.

Ive tried to search up documentation and several tutorials but it seems like there's nothing out there. Maybe this is something simple to do, but I just cannot figure it out.
My goal is to make an application that has a series of questions that you fill in. Some tick boxes and some text fields where you fill in some more info. This survey would be on one VC and you scroll down through the questions. After all this I want to append the data to the apple numbers app on the iPad with a specific structure.
How would I go about this? Any resources you can recommend?
T.I.A
I believe that you should generate and export a .csv file with all the data you collect in the app. Save that file to iCloud Drive or to another cloud solution you can integrate in your app, and then access it and open it using Numbers.
So I've got this idea for a project and am looking for some solutions on how to complete it. Right now I have an iphone app set up to take in a bunch of user information and an image of a signature they draw. I have a pdf waiver that needs to be populated with this data and the signature. Is there any way to overlay this data on the form? Is there a way to create an html document with the form as the background and then the data laid over the top with css?
If this is possible, then what's the best way to get that new pdf or html page to a website/folder/email.
Would appreciate any help with that. Thanks!

I need to create one sample application for NITF-News Industry Text Format in iphone. I don't know how to begin. What Language(Css,Javascript like that..) should i use to read the content from .xml(NITF) files and design the article pages in iphone.I red from this Link. NITF uses the eXtensible Markup Language(xml) to define the content and structure of news articles.
Please anyone give me some guidance to start.
Thanks in Advance
Use NSXmlParser to parse the data.. Then display the content accordingly..
First, I would to thank everyone for all the help they provide via this website. It has gotten me to the point of almost being able to release my first iPhone app!
Okay, so the last part I have is this: I have a game that allows users to save their high scores. I update a plist file which contains the users Name, Level, and score.
Now I want to create a screen that will display the top 20 high scores. What would be the best way to do this? At first I thought possibly creating an HTML file with this info but am not even sure if that is possible. I would need to read the plist file, and then write it out as HTML. Is this possible? To write a file out as HTML?
Or an even better question, is there a better way?
Thanks in advance for any and all help!
Geo...
This is what UITableView was made for. Read your plist into an array and feed the contents to the table view through its datasource/delegate methods.
The iPhone makes it really simple to snarf down an image from the web; you can turn a URL into a UIImage in one line of code. So I'd like to enable my app (an educational puzzle game... my first!) to download some random images to make it more interesting and dynamic.
I thought about using Kodak's image of the day RSS feed, but I'm having quite a time figuring out how to parse it. Rather than being a simple list of image URLs, it seems to reference a bunch of "jhtml" URLs, which run Javascript to display the images in your RSS reader. Is this intentionally obfuscated, or am I missing some basic step to parse this?
I also tried the Astronomy Picture of the Day, via this RSS feed, but it's just the original page's HTML stuffed into CDATA... ugh.
So I guess this is really two questions:
Is there a simple way to parse these feeds to actually get at the JPG URLs on the iPhone?
Is there a better source for "picture of the day" type images?
PS: I'm using NSXMLParser, which I learned to use here.
I would recommend going with something that has an API, perhaps the Flickr "Interestingness" feed:
http://www.flickr.com/services/api/flickr.interestingness.getList.html
There is an objective-C library written to help with accessing Flickr but not sure if this API call is included:
