Replacing a UIView backing layer with CAShapeLayer and ensuring the path is animated on frame change
Posted by Andy Yardley in iPhone on October 29, 2015
Recently i’ve started making a lot of use of CAShapeLayers as the backing for a UIView subclass. The main reason for this is it gives me a reusable high performance background which is especially useful as I find a lot of my apps usually have similar looking views with different content. This is all well […]
Objective C & iOS Weak Singletons
Posted by Andy Yardley in Development, iPhone on February 3, 2013
Temporary shared memory management is always a bit of a difficult problem to solve. There are various well known ways of dealing with this problem but recently i’ve come across a novel solution to this problem that actual takes advantage of Objective C’s Automatic Reference Counting (although it could also work without ARC) The singleton […]
Events App
Posted by Andy Yardley in Development, iPhone on August 8, 2012
Over the last few months i’ve started putting together an app for tracking sporting events. A lot of the ones i’ve used have always lacked in the ability to see what is available on a day. They usually have a horrible list that requires lots of scrolling and it’s especially clear. So I set about […]
iOS Font Name Problem
Posted by Andy Yardley in iPhone on June 14, 2012
I wanted to followup my previous post about iOS font positioning with something else I came across yesterday. While adding a custom font to a new app there was a problem with the font not appearing in the simulator or on device. It had been added correctly to the .plist, included in the project and […]
Tube App
Posted by Andy Yardley in Development, iPhone on May 3, 2012
My next app is a simple one. But one which i’ve found quite useful for the last couple of weeks and one I hope when it’s live on the store will be useful to other people. The purpose of this app is two fold. First is to solve the problem at hand, and second is […]
Custom iOS fonts and how to fix the vertical position problem
Posted by Andy Yardley in Development, iPhone on April 24, 2012
Every new iOS design I have to implement uses custom fonts. A few years back this would have been impossible but luckily since iOS4 it’s been reasonably simple to add your own fonts to iOS Apps. The process is as follows: Add the font (*.ttf or *.otf) to the project Make sure it is added […]

Apps are like buses
Posted by Andy Yardley in iPhone on March 21, 2012
At the moment the stuff i’m producing is like the bus service. Nothing for ages then loads all at once!! Anyway in September I took a few weeks out of working for a change (and decided to work – FFS), I needed a bit of a break from the grind and for a long time […]
Fixing audio sync with FFMPEG
Posted by Andy Yardley in iPhone on March 20, 2012
Yesterday a client asked me if there was anything I could do with a piece of video they had produced in which the audio was out sync with the video. Normally when I come across this kind of problem is you get the audio happen after seeing the images move. But this one was the […]
Presenting – Snoozes
Posted by Andy Yardley in Development, iPhone on March 19, 2012
Previously I covered the reasons for building an app which could revolutionise the wake up alarm business (or not as i’m not even sure it’s a business anymore), but now it’s time to go over a bit more what it will do. So i’d like to present Snoozes. The intention of snoozes is the give […]
