How could I access a website and turn components of the website into strings. For example taking information from Facebook posts. I have done a little searching but can't find any good tutorials or anything useful.
Try looking at this tutorial. It should get you more familiar on the subject and start you off on the right track.
As it states at the beginning of the tutorial...
How to Parse HTML on iOS
Let’s say you want to find some information inside a web page and
display it in a custom way in your app. This technique is called
“scraping.” Let’s also assume you’ve thought through alternatives to
scraping web pages from inside your app, and are pretty sure that’s
what you want to do. Well then you get to the question – how can you
programmatically dig through the HTML and find the part you’re looking
for, in the most robust way possible? Believe it or not, regular
expressions won’t cut it! Well, in this tutorial you’ll find out how!
You’ll get hands-on experience with parsing HTML into an Objective-C
data model that your apps can use.

I'm currently exploring the capabilities of custom passes in Apple Wallet.
One thing I would like to do is enable users to be able to go to my website if they click their gift card's icon.
However, after looking through the documentation - there doesn't seem to be any support for this basic ask.
The closest thing I was able to find was adding URLs to the back of the custom passes. Anyone know of a workaround?
I'm looking for the same thing.
I'm surprised people praise Apple Wallet passes that much, when it's really bad to work with.
Everything is file based, and you have to create a physical zip-file.
Google's approach is much better imho: everything is done via an API, so the pass itself is just a url with a token. Sharing a Google Pass is so much simpler and works everywhere.
Updating a pass is simple; just call the Google Api and everything will be ok. Images and assets are urls. Much much better to work with.
Updating an Apple pass involves fricking Push notifications, it's mind bogglingly complex compared to Google's solution.
Oh well
Alright — this sort of question shows my naïveté but I am asking it nonetheless so I don't venture down the wrong rabbit hole while trying out this app.
I'm making what amounts to a news app. Imagine taking a Wordpress blog and fitting it to iOS. Now, here's my question — what sort of feed / architecture should I be using to push information from my Wordpress server to my app? I would assume RSS using AFNetworking, but that seems to cause some rough edges, and all tutorials that I see end up pushing to a web view instead of a scrollview with nice, rendered text. Plus, none of the same tutorials seem to have anything further than the initial feed (loading more than the initial 10 stories given, for example).
I've already committed a few hours to trying the RSS / AFNetworking approach, but is there a significantly better alternative that I just haven't come across. (Note that I do have access to the back-end of my Wordpress site, i.e. it isn't somebody else's)
If you are building an iOS app that connects to WordPress, I suggest you to access the website data by an API instead of feed, then you can hit the API from your app and manipulate the data as you want.
If you have access to the WordPress backend, check the Thermal API which is a plugin that will probably solve your problem.
Cheers,
I would suggest that you look at https://wordpress.org/plugins/json-rest-api/ this is to be added to the core of wordpress so it would seem that is the way to go I think.
By the way I am working on the same type of thing as you.
I think the most popular Wordpress API is the one that comes with Jetpack. You can find its documentation here: https://developer.wordpress.com/docs/api/
If you just want read access, then i think the easiest way to do so is by using: https://github.com/evermeer/AlamofireJsonToObjects/blob/master/AlamofireJsonToObjectsTests/WordpressTest.swift
If you also want write access, then you have to implement Oauth2. For that you can select a library from: https://cocoapods.org/?q=oauth
i have a website, its to exchange links, files... to say it quickly it's my 'version' of twitter+megaupload,
Well, users add links all the time and so on, but i would like user be able to syinch his bookmarks from the browser to the ones he has at his profile of mywebsite,
Where should i look into?
Basically i need to be able to:
- Acces bookmarks file (1)
- being able to send the urls to my service ( 2 )
- maybe adding the login feature (in the future)
I was google'ing about this for ages few weeks a go and i kind of give up, because i'm ok with PHP and JS, but with this plugin languages i'm very lost. So i decided posting here, wich always brings positive answers
(1) - > I don't even know where to start
(2) -> i was thinking to have a website.com/auto_import_no_confirm.php?url=[URL] and put it in a for each.
how many different languages and extension files do i have to work with? I really need any kind of tip with point (1)
feel like?
-edit-
Just found This -> https://developer.mozilla.org/En/Code_snippets/Bookmarks
wich really looks like i need, but where do i place this code?
thanks!
Might not be a bad question, but there are too many subtopics raised to answer that. (And there is too much tagspam as well. Break up your question into PHP- and Javascript-specific tasks, when you have devised the general application scheme.)
But to get started, download similar Firefox extensions (.xpi) and unzip them to inspect the general structure. You'll find examplary code for bookmark handling and invoking remote APIs pretty quickly. And basically you only need Javascript for the extension itself. (It sounds like your extension does not need much UI.)
And there are many tutorials on designing Firefox addons: http://roachfiend.com/archives/2004/12/08/how-to-create-firefox-extensions/ or http://www.google.com/search?q=firefox+develop+an+xpi
The good news first, you won't need much more than javascript if you just want to access bookmarks and send them to a server, neither on firefox nor on chrome.
But still you'll have to make yourself familiar with the apis of the browsers and learn how to develop extensions.
However, both Mozilla and Google provide all necessary information on their developer sites.
For Chrome, this is a good place to start, you'll find the api for bookmark access here.
The Corresponding site for Firefox can be found here, with information on bookmark access here.
I want to make a program that takes as user input a website address. The program then goes to that website, downloads it, and then parses the information inside. It outputs a new html file using the information from the website.
Specifically, what this program will do is take certain links from the website, and put the links in the output html file, and it will discard everything else.
Right now I just want to make it for websites that don't require a login, but later on I want to make it work for sites where you have to login, so it will have to be able to deal with cookies.
I'll also want to later on have the program be able to explore certain links and download information from those other sites.
What are the best programming languages or tools to do this?
Beautiful Soup (Python) comes highly recommended, though I have no experience with it personally.
Python.
It's fairly easy to write a simple crawler using python's standard libs, but you'll also be able to find some existing python crawler libraries available on the web.
I am unlucky to be in charge of maintaining some old Yahoo! Store built using their RTML-based platform.
Recently I've noticed that HTML code generated by some RTML functions is sprinkled all over with "padding images" (or whatever is the conventional name for those 1x1 pixel images used to enforce layout). I have nothing against using such images, but... all those images are supplied with an ALT attribute like this:
<img href="http://.../image1x1.gif" alt="pad">
With all due respect to the original authors of RTML, but they must have been smoking something when they came up with this "accessibility enhancement"... :-(
Anyway, here are my questions:
Does anybody know a list of all RTML functions that generate HTML with all these "pad" images?
Is there any way to get rid of all those alt="pad" attributes without rewriting a lot of RTML code?
NB: This may sound a little cynical, but improved accessibility is not the main goal here. The main goal is to stop exposing those moronic alt="pad" attributes to Google and other smart search engines. So client-side scripting is not going to help, as far as I know.
Thank you!
P.S. Probably, most of you are really lucky and never heard of RTML. Because if somebody would establish a prize for software products based on
commercial success
------------------
usability
ratio, this RTML-based "platform" would probably win the first place.
P.P.S. Apparently someone from Yahoo! finally listened, because I can no longer find those silly "pad" tags in the RTML generated for our store. Nevertheless, one of the ideas offered in response to my original question does provide a very practical solution - not just to the original problem but to any similar problem with RTML platform. See the winning answer - it's really good.
The only way I see is to have your own website front-end that will filter whatever you want from the RTML site....
for example, your rtml site is at http://rtmlusglysite.yahoo.com/store/XYZ01134 , you could host a simple PHP front-end at http:://www.example.com that would be acting like a "filtering" HTTP web proxy, so http://rtmlusglysite.yahoo.com/store/XYZ01134/item1234.rtml would be accessed by http://www.example.com/item1234.html
It's not an ideal solution, but it should work, and you could do some more fancy stuff.
Nice try from the other posters, but there is a very simple RTML command that will do it. . .
TEXT PAT-SUBST s GRAB
MULTI
HEAD
BODY
TEXT #var-with-alt-tag-equals-pad-in-it
frompat "alt=\"pad\""
topat ""
The above RTML will find all instances of alt="pad" and replace it with nothing.
Well you're right on RTML being relatively untraveled :)
Do you have a way to add your own attributes to these images tags? If so, would it be possible to override the alt attribute? If you specify alt="", I would think that would override Yahoo's... Otherwise consider putting a useful alt tag in there for the blind and dialup types.
It's the first time I'm hearing about this platform, but here is an idea: if you can add javascript to the pages, you could write a function that will run after the page has loaded and remove all the alt="pad" attributes from the page.
Unfortunately this solutions works only with browsers that know about scripting, so lynx or some other text based browsers might not support it.
I have shared a link official RTML guide from yahoo. Hope it will help. Thanks!
