UIImage caching

Mon, 28 May 2012 17:09:22 +0100

Last week I discovered that it was possible to load unbundled images using the iOS [UIImage imageNamed:] method:

Interesting. I didn’t know that you can use [UIImage imageNamed:] (and its caching benefits) for non-bundled images: http://stackoverflow.com/a/2324544

I’ve since created a UIImage category that allows you to easily drop in the code into any project - available here on Github.

Siri & Caller ID

Fri, 04 May 2012 19:23:22 +0100

I just filed a bug report with Apple: rdar://11385707

Siri should announce caller ID when connected to Bluetooth headset / audio device.

I think this would be particularly useful while driving. I use the Jawbone Jambox in the car and I have to glance at the iPhone screen to see who’s calling when I receive an incoming call.

Bonus points go for announcing caller ID for incoming text messages.

If you’d like to see this feature in iOS, be sure to file a similar bug report.

iOS App Marketing - Quick Tips

Thu, 12 Jan 2012 15:15:00 +0000

Display ads - waste of money. The return on banner/text ads is very disappointing. Google has the best CTR. Facebook are well-targeted, but are expensive (if your app sells at less than €3, then it might not be worth your while). BuySellAds allow you to purchase ad-space on some popular blogs - the service itself is great, but sites I’ve advertised on didn’t give a good CTR.

Journalists - big blogs (Techcrunch, etc) are worth contacting but don’t expect to get featured, unless you’re VC backed and have raised a bunch of money. Focus on smaller, niche blogs - for example, a Russian iOS blog caught wind of a Muud.io sale and subsequently sales spiked 400% for couple of days. Local journos are usually eager to help out too.

App review sites - a handful of the bigger ones are worth contacting. A personal email works best if possible - press releases are usually ignored. Most are a waste of a promo code however.

Apple - extremely difficult to get noticed. Build a great app and you’ve a better chance, but don’t count on getting featured. If you have any contacts in Apple, it’s worth getting in touch - you might at least get your app in front of the iTunes editorial team for review (even so, you’re still not guaranteed placement).

Twitter, Facebook, Google+ - Worth maintaining a presence. The more active you are the better. Twitter is #1 referral stream for visitors to the Muud.io website.

Stuff 'n Junk, 2011

Mon, 19 Dec 2011 14:15:00 +0000

Some cool things I discovered this year…

MacBook Air (Mid 2011)

For the past three years or so, I’d been working off a 15” MacBook Pro, and it was an absolute work-horse of a machine. With the introduction of Lion, and Xcode 4.x, the MBP started to become a little sluggish and couldn’t keep up with the demands of my daily development duties (alliteration FTW).

I’d spent a lot of time researching which Mac to buy next and had originally planned to pick up an iMac for the extra horsepower and use my iPad as a travel “computer”. However, once Apple released the i7 MacBook Air, a lot of other developers made the switch and were singing its praises. The allure of an ultra-portable Mac, with SSD, and an extremely powerful CPU were just too much to resist. I picked up the maxed out 13” i7 model and can confidently say that it is the best machine I have ever owned.

Ruby on Rails

A simple-yet-powerful framework that makes it easy for web-luddites like myself to build web services. I learned the basics using this ebook and some online video tutorials. Thanks to RoR, I no longer have to pay licensing fees for Windows Server (it can run on Linux, Mac, or Windows), and I can quickly prototype and test services directly on my Mac. (I actually started with RoR last year, but built my first full-scale service this year - Muud.io).

Linode

Cloud-based VPS provider with a large number of Linux images to choose from. Pricing is good, uptime is great, and the community/documentation is fantastic. Linode also provide load-balancing services, called NodeBalancers, as well as an iPhone app to manage your servers and DNS entries.

iTunes Match

I’ve only had this for a few days, but it’s a service that I’ve been wanting Apple to provide for years. I no longer have to carry around an external USB drive containing my music library - it’s all in the cloud, saving over 50GB on my MacBook Air’s SSD. I can stream music to my MBP, and download on-the-fly to all of my iOS 5 devices.

5by5 Podcasts

I may have actually discovered 5by5 last year, but it became an integral part of my daily routine over the past year. The shows are great, Dan Benjamin is an excellent host - some of my favourite shows are: The Talk Show, Back to Work, Build and Analyze, The Critical Path, Founders Talk.

The Verge, The Vergecast, On The Verge

Everything I loved about Engadget - in-depth reviews and editorials, quirky sense of humour, and an hilarious podcast - combined with a new sense of style and some excellent video segments.

Sparrow

I use Gmail a lot and had previously plugged my accounts into Apple’s Mail app. Sparrow brings some of Gmail’s best features to a native client. The UI is somewhat of an acquired taste, but it works well for me.

Fantastical

A much simpler way to enter data into iCal. Just type plain text and Fantastical will parse it into a meaningful iCal event.

1Password

Use a single password to manage random passwords for every site that you sign up for. Very clever, if a little awkward sometimes. Still, much easier than resetting forgotten passwords…

FreeAgent

Online accounting software that allows me to input transaction data and forget about the rest. If you’re running a small business, definitely give it a try.

Film & TV

Disclaimer: I missed a lot of big movies this year!

The Guard - Comical caricature of Irish mentality.

Super 8 - Nostalgic, creature movie.

Attack the Block - Like Shaun of the Dead, but with aliens.

The Walking Dead - Zombies! Horror! Intense!

Boardwalk Empire - The Sopranos, set in Atlantic City during the prohibition era.

Community - Hilarious, geeky comedy, set in a community college.

Various new music

Another disclaimer: I didn’t get to try out a lot of new music this year either.

The Black Keys - El Camino

Death Cab for Cutie - Codes and Keys

The Decemberists - The King is Dead

Feist - Metals

Delorentos - Little Sparks EP

Arctic Monkeys - Suck It and See

Pretty much everything Apple did this year

iOS 5, iCloud, Siri - too much awesome for one year! Except for Lion; let’s not open that can of worms right now ;)

Scripting EirText for Mac in Terminal

Fri, 25 Nov 2011 16:42:04 +0000

Using EirText for Mac’s command line / Terminal commands:

All you need to do is launch EirText as usual and make sure that you have an account set up within the app. Make a note of your username and the network you’re using (e.g. O2.ie, VoIPCheap.com, etc). You can quit the app once you have an account ready for use.

Here’s an example of how it works:

/Applications/EirText.app/Contents/MacOS/EirText -u USERNAME -n NETWORK -rRECIPIENT1,RECIPIENT2,RECIPIENT3 -m ‘MESSAGE TEXT’

Now, just a quick explanation of those arguments:

USERNAME is the username that you use to log in to your account

NETWORK is the name of your provider/network, for example O2.ie

RECIPIENT1… is a comma-separated list of recipient phone numbers

MESSAGE TEXT is the body of the message, surrounded by single-quotes

So, for example, let’s say I’m a Vodafone.ie user and my username is 0871234567. I want to text two numbers – 0861111111 and +447547777777.

This is what I’d type into the Terminal:

/Applications/EirText.app/Contents/MacOS/EirText -u 0871234567 -n Vodafone.ie -r 0861111111,+447547777777 -m ‘Hi there. This is a message sent from the EirText app for Mac!’

Hit return and you’ll see something similar to the following output to the Terminal:

2011-06-16 14:10:22.135 EirText[5155:903] 181 messages remaining.

2011-06-16 14:10:22.136 EirText[5155:903] Sending message to 2 recipients…

2011-06-16 14:10:29.182 EirText[5155:903] Message sending successful.

2011-06-16 14:10:29.182 EirText[5155:903] Quitting EirText.

If you’ve never coded before, have a look first at Visual Basic, then C++ or C#. You can get Microsoft’s tools online for free. Just do a Google for Visual Studio. There are loads of tutorials online for VB and C# - I’d recommend trying out the latter as it’s probably more relevant (C# can be used for Windows Phone programming). This also lets you try your hand at programming without having to buy a Mac.

Once you have a bit of coding under your belt, you’ll be ready to move on to Objective-C, which is the iOS & Mac programming language. As you can guess, it’s an enhanced version of C, but it looks quite different. You’ll need a Mac for this, but you might as well go ahead and buy one - you’ll thank me later :)

Apple supply a huge amount of sample apps with the iOS SDK. All you need to do is fire up Xcode, click on Help and then on Documentation and API. There should be a link to Sample code somewhere on the main page of the docs. Xcode is available on the Mac App Store for free.

Apple also offer video tutorials on iTunes U. Check out the Stanford iOS course on iTunes U while you’re there. Jeff Lamarche’s blog is a great resource also.

To be honest, you could read and read, but the best way to learn is to download the Apple samples and tinker with them until you get a feel for how they work. Try out code, break your code, and learn how to fix it… Unfortunately it all takes a bit of time, but it’s worth it once you get your first app running on-device.

Wanted: Search and in-app purchase APIs for iTunes media on iOS.

Fri, 14 Oct 2011 11:12:00 +0100

UPDATE: Apple have marked this feature enhancement as a duplicate of 7040203

Filed as Radar # 10286028

Currently, apps have to jump into the iTunes Store app on iOS when prompting the user to purchase songs & video.

The user taps a “Buy in iTunes” button in the third-party app. This jumps into the iTunes app. The user must then tap the Buy button in iTunes and then enter their Apple ID password.

To reduce the number of user-actions and potentially increase on-device music purchases, Apple could create an in-app purchase API for music, similar to standard in-app purchases.

A native search API for iTunes could be created, which would mimic the current JSON API. A standard system UIViewController could be used to display search results and handle the purchasing experience. Songs downloaded would be added to the user’s Music / Video apps.
