On the twitters, friend Justin Driscoll mentioned: iOS needs a block-based UIAlertView. So many currently-delegate based interfaces would be better served by block callbacks. I’ve wanted the same. I’ve also wanted to contribute more open source code. With some time on my hands, I threw together RooAlertView. As I mention in the README, I’m not [...]

While looking for how to setup user scripts in Xcode 4 I stumbled into Tony Arnold’s Xcode-4-Uncrustify-Automator-Services on github. Creating a service with Automator answered my original, but the real find was uncrustify. From the uncrustify website: The goals of this project are simple: Create a highly configurable, easily modifiable source code beautifier. Since Tony [...]

I’ve been working with Google’s Account Authentication API lately. Specifically working with ClientLogin. One problem I ran into is that ClientLogin says that it may return a response of 403 with an error of “CaptchaRequired”. When that happens you’re supposed to display the provided CAPTCHA image to the user and have them give the answer. [...]

I was waiting for a MySQL migration to finish when I said to a friend: “mysql should have growl support to tell me when a lengthy operation is done”. 10 seconds later that became: “Even better, there should be a command like ‘time’ that would growl when whatever command you give it is done”. 3 [...]

I’m going to be showing some slides (and talking over the slides) and doing a demo of RubyCocoa tonight for the Boise ruby brigade. I’ll post the code and slides tomorrow for anyone that might care. Hopefully someone learns something (minimally, I think I’ll get a lot out of it)

Update: The traineo guys provided an API and I updated the widget. See: TraineoWeight.wdgt Updated Like most Americans I’d prefer to be less fat. To help me with that goal I’ve been logging my weight on traineo.com. They offer plenty more than just weight tracking, but I haven’t gotten into all that quite yet. Anyway, [...]

I’m working on an application that will be going into a private beta pretty soon, followed by a public beta. One of the things I wanted to do was make sure the application stopped working after 30 days from when it was built. This is to make sure the beta testers are running the latest [...]

Key-Value Coding is part of the magic behind Cocoa’s bindings. Up until yesterday I had only been binding to an ObjectController or to an ArrayController backed by Core Data. This is very powerful, but bindings pre-date Core Data so clearly not a necessity. So yesterday I went to bind an NSProgressIndicator’s ‘isIndeteriminate’ to a BOOL. [...]

To get the icon that represents an application with no custom icon (default application icon) just call: [NSImage imageNamed:@“NSDefaultApplicationIcon”];

When using Core Data, Boolean values as an attribute are represented using NSNumber. That’s all fine and good, but it requires you to use [NSNumber numberWithBool:YES|NO] when you set the value. NO is defined as: define NO (BOOL)0 we have an issue. 0 is also ‘nil’. Just below the definition of NO we see nil: [...]
