Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.
Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Greetings, NSHipsters!
As we prepare to increment our NSDateComponents -year by 1, it's time once again for NSHipster end-of-the-year Reader Submissions! Last year, we got some mind-blowing tips and tricks. With the release of iOS 7 & Mavericks, and a year's worth of new developments in the Objective-C ecosystem, there should be a ton of new stuff to write up for this year.
Submit your favorite piece of Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!
Here are a few examples of the kind of things I'd like to see:
NSStringFromSelector(@selector()) as a safer way to do KVC / KVO / NSCoding.
| static BOOL PSPDFIsDevelopmentBuild(void) { | |
| #if TARGET_IPHONE_SIMULATOR | |
| return YES; | |
| #else | |
| static BOOL isDevelopment = NO; | |
| static dispatch_once_t onceToken; | |
| dispatch_once(&onceToken, ^{ | |
| // There is no provisioning profile in AppStore Apps. | |
| NSData *data = [NSData dataWithContentsOfFile:[NSBundle.mainBundle pathForResource:@"embedded" ofType:@"mobileprovision"]]; | |
| if (data) { |
