Objective-C in web development

Is it possible/feasible to use ObjC (not necessary the Apple flavor) to develop server-side web applications? Is GNU ObjC toolchain at all usable? Please share your thoughts and experiences.

Upd. I'd like to hear more answers with concrete practical experience, like "i tried/use .... and it is great/sucks, because...". 300 bounty!

Upd2. The rationale behind my question is that I'm about to develop an iOS app with a large web-based backend and thought it would be nice to use the same toolchain/IDE for both parts. But, alas, the answers so far show that this is not going to be feasible. Thanks everybody for taking time.

Apple Push Services created instead of Apple Production iOS Push Services

I'm trying to create a certificate for Production iOS Push Services. Instead I get an Apple Push Services. How can I create a dedicated Apple Production iOS Push Services certificate?

The top certificate is what I used to get. The bottom one is what I now get.

I use Pusher application to test my push notifications certificate and it cannot read the p12 of the new Apple Push Services.

Speeding-up the Apple review process for iOS application for patches and hotfixes

Good day!

Is there any way to upload a quick-fix for my application, approved by Apple some days ago? Or should I wait for another 2 weeks for re-review again? :)

Rounding in Swift with round()

While playing around, I found the round() function in swift. It can be used as below:

round(0.8)

Which will return 1, as expected. Here's my question:

how do I round by thousandths in swift?

I want to be able to plug in a number, say 0.6849, and get 0.685 back. How does round() do this? Or, does it not, in which case, what function does?

iPhone WebApps, is there a way to detect how it was loaded? Home Screen vs Safari?

I have an iPhone Web App. I'm interested in detecting if the app was loaded either from: 1. iPhone Safari 2. iPhone installed web app (via the add to my homescreen) which loads without the safari bars.

Any ideas?

iOS codesigning specs

I want to create a tool for codesigning iOS apps on a linux server remotely.

I know codesign is oss but relies heavily on the keychain and is not as portable.

I know Adobe has a codesign utility for win and mac within flash that takes the provisioning profile, .p12, and .cer and signs the app.

UDK also does something similar but doesnt seem to need the .p12 ( http://udn.epicgames.com/Three/AppleiOSProvisioning.html )

So my question is really, what is the process they are doing so i can recreate a tool that is cross platform that can do it.

iTunes Connect: How to choose a good SKU?

I'm reading the iTunes Connect Developer Guide as I'm trying to add a new application to my iTunes Connect. I'm a bit confused about the SKU number which I should provide. On page 81 in the above developer guide, they provide an example of their data for their application Orange Ball.

They have chosen Orange_Ball_01 for the SKU Number. What is the 01 indicating -- that it is version 1? Why use underscore? Why not just type "OrangeBall", if that SKU is not used?

How to force a UIViewController to Portait orientation in iOS 6

As the ShouldAutorotateToInterfaceOrientation is deprecated in iOS 6 and I used that to force a particular view to portrait only, what is the correct way to do this in iOS 6? This is only for one area of my app, all other views can rotate.

Thank you.

dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid

since an update to 10.8 I get the following error, when trying to do a sudo command, which is pretty annoying.

dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid

What does that have to mean? I hope anyone can help.

Storyboards vs. the old XIB way

I am new to iOS and was wondering which is the best to learn. I have read some of the answers here and SO, but some people say use Storyboards will others say learn XIBs first. Is there any real benefit to learning XIBs? Are XIBs easier to understand and will help with storyboards?

How to check the number of updates in the Sales and Trends Module of iTunes Connect

I have a question that is not exactly code-related. However, I thought that I would ask it here because many developers seem to have some experience with this issue.

Recently Apple updated its Sales and Trends module to a different interface. I used to be able to check to see how many updates I had for an app each day by clicking on an "updates" tab.

However, in this new module, I cannot seem to find this feature! I really need to have access to something like this and I was hoping to be able to continue to depend on Apple's website to find this information.

Mobile Safari/ iPhone Mail.app HTML design issues: prevent autolinking and styling auto-links (dates, addresses, etc.)

i am trying to design an HTML e-mail that should also look good when it is read on mobile devices. My biggest problems are with the iPhone (iOS 4): its mostly undocumented "auto linking" feature really bugs me.

Autolinking seems to appear on

• phone numbers (this is the only documented feature, as explained here)
• addresses
• dates

Is there any documentation out there on how to

1. disable auto linking for dates and addresses
2. "correct" the autolinking via microformats or something similar (so the results are better than they actually are with iOS 4)

Any information, hints, or clues are really appreciated because there does not seem to be any information out there whatsoever.

Apple touch icon isn't showing up on the home screen

I'm using the following code to get touch icons for mobile devices - it's based on the html5boilerplate/mobile example:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;">

<!-- For iPhone 4 with high-resolution Retina display: -->
<link rel="apple-touch-icon-precomposed" sizes="114x114" rel='nofollow' href="/img/touch/h/apple-touch-icon.png">
<!-- For non-Retina iPhone, iPod Touch, and Android 2.1+ devices: -->
<link rel="apple-touch-icon-precomposed" rel='nofollow' href="/img/touch/l/apple-touch-icon.png">
<!-- For nokia devices: -->
<link rel="shortcut icon" rel='nofollow' href="/img/touch/apple-touch-icon.png">

<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="apple-mobile-web-app-status-bar-style" content="black">

But for some reason, the iPhone is still giving me problems for the home screen icon. All I get is that annoying screenshot icon.

I've included the other meta tags here in case they shed some light on why it isn't working. I've tried reordering the tags.

Can anyone think of anything that might stop the icons being used?

I've used html5boilerplate/mobile as a test case - I'm able to browse to their site and add the icon to the home screen on my iPhone (4S iOS5). I've tried copying their code, folder structure, and icons into my own site, but this didn't work.

Any ideas?
