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 [...]

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: [...]

Somewhere there exists a list of words you shouldn’t assign as attributes within Core Data. I don’t know where that list is, and today I got bit by not knowing. I tried to use the word “deleted” as an attribute. No matter how hard I tried to set the “deleted” value and regardless of what [...]

NSString has a great little method prototyped as – (id)propertyList What does it do? To quote the docs: Parses the receiver as a text representation of a property list, returning an NSString, NSData, NSArray, or NSDictionary object, according to the topmost element. If you started staring at CFPropertyList(…) functions, just trying to figure out how [...]

I’m in debt to a lot of people for their help with rooVid. For some, the help was directly pointed at rooVid via questions I asked or suggestions made. For countless others it was via the wonderful blessing that is the web. One of the things I get a kick out of is when I [...]

Appcasting seems like a great idea to me. In short, an appcast is an RSS feed with an enclosure that is your latest release. I was turned on to appcasting when I found out about Sparkle. Sparkle made it super easy for me to add “check for update…” support to rooVid (it’ll be in beta [...]

I’m trying to load a NSPanel with a controller that inherits from NSWindowController. So my controller’s init calls: self = [super initWithWindowNibName:@"NibNameHere"]; and then I call showWindow on my now init’d controller object. All pretty straight forward. Problem is that the dang “window” assigned to files owner wasn’t showing up. Well, to make a painful [...]
