Deploying to Heroku from TeamCity
Previously I discussed our TeamCity configuration using RVM and mentioned that we often use git to deploy projects. Today I’ll share an example of how a TeamCity build agent can trigger deployments of a application hosted on Heroku and some of the challenges I found.
Using RVM on TeamCity build agents
We have been using TeamCity to manage the continuous integration, testing, and deployment of many of our recent projects. We have also been using RVM on all of our recent Rails projects to allow us to install multiple ruby versions and create isolated gemsets for each project. RVM proved to be particularly useful on our …
UIView Frames and Bounds
All UIViews have frame and bounds properties which define their dimensions. The similarity of these properties can cause some confusion when attempting to determine which property to use to calculate view sizes or reposition views. The frame of a view is given in the coordinates of its superview so a view controller’s view’s frame will …
Testing iPhone View Controllers
I have been writing tests around my iPhone apps’ view controllers in order to follow the same TDD practices we use in other environments. Writing tests first has changed the way I structure my code in a couple of ways which I think offer immediate and emergent benefits for my applications. Most of an iPhone …
Multiple Environments in an iPhone Project
I’ve been following a Rails convention and defining multiple environments for my iPhone projects. This allows me to quickly switch application wide settings when running a test, development, or production version of the app.
Automatically deploying to Engine Yard Cloud
I’m working on a application which is deployed to Engine Yard’s Cloud infrastructure and I wanted to automatically redeploy the application whenever our tests passed on our continuous integration server. Engine Yard will eventually allow us to push a branch to our cloud environment from git (ie “git push engineyard master”) but until that is …
Unit testing JavaScript with Blue Ridge
My current rails project is using Blue Ridge and the tool set it bundles together (Rhino, env.js, Screw.Unit, and Smoke) to write test driven JavaScript. The ability to write tests of my JavaScript, in JavaScript, as efficiently as I can test other languages has forced me to rethink how I structure my work and I’m …
Code Formatting in Xcode
Using Xcode 4? Take a look at Code Formatting in Xcode 4 Working in Xcode I almost forgot how much I like IntelliJ’s code formatting tools. Luckily for me Mike Smith recently pointed out that UniversalIndentGUI can be used to setup your own code formatting in Xcode.
Resizing views around the keyboard
Most of my iPhone apps need to accept keyboard input somewhere and that means I need to reposition my UI elements such that the keyboard does not hide the field the user is typing in. The iPhone Application Programming Guide offers one example of Moving Content That Is Located Under The Keyboard but this is …
Loading UITableViewCells from a nib file
While working on iPhone applications I have found it useful to load as much of the UI layout and styling from nib files as possible. As a result I often want to load the cells for a table view from a nib file and created a factory class to handle this behavior every time I …
