Undefined symbols for architecture i386 – Reachability
Today I add the Reachability classes to an app I am working on, added my #import Reachability.h to the correct files and then implemented a method to check if the device was using wifi. When I hit build, I got the following error. Undefined symbols for architecture i386: “_SCNetworkReachabilityCreateWithAddress”, referenced from: +[Reachability reachabilityWithAddress:] in Reachability.o […]
Push Notifications for iOS Apps – PushWoosh
I came across a service for push notifications, probably a bit late to the table but I have only just needed push notifications in my apps. Being a web developer my original idea was to host the service on my hosting and then that way I would be able to send as many notifications as […]
Using Current location in Apple Maps
I was updating one of my iOS apps that used to open up the Maps Application to show directions from the current location to a set of coordinates. Before Apple Maps was introduced we could use “Current Location” as a way for Maps to use the users current location (http://maps.google.com/maps?saddr=Current%%20Location&daddr=51.535455,-0.247557) this no longer works in […]
Add a custom font to iOS app

After a bit of research I found that it was down to using floating numbers to define the frame of the label. Basically, floating numbers use decimals […]
Git pull and push asks for username and password every time
I recently rebuilt my computer and cloned a git repository that I had been working on. Once I started working on the project again, I realised that every time I was executing a pull or push command in git bash it would ask me for my username and password whereas before it used to only […]

I recently encountered a problem with a website I was working on. I stopped being able to access the site. All my browsers were not able to connect to the server. I was able to access all other sites that I needed. I contacted the host of the website and requested that they check my […]
iOS Navigation Bar behind status bar after closing full screen MPMoviePlayer

WordPress Site stuck in maintenance mode.
I was updating a plugin on a WordPress site I maintain and the process just stopped working. The site was stuck in Maintenance mode. To get out of maintenance mode I had to delete the file ‘. maintenance’ from the root of the site. Once I had done this the site instantly came back up.
