This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
Howdy howdy, NSHipsters!
If you alloc init
an NSCalendar
, you'll notice that New Year's Eve falls on a Monday this year, a.k.a. "the day NSHipster is published every week". What fun!
So in celebration of the upcoming year++
, I thought it'd be fun to compile a list of some of your favorite tips and tricks of the trade. 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:
// clang -framework Foundation -fobjc-arc -O3 test.m | |
#import <Foundation/Foundation.h> | |
@interface Slice : NSObject | |
@property NSInteger start; | |
@property NSInteger length; | |
@end | |
@implementation Slice |
// Usage example: | |
// input image: http://f.cl.ly/items/3v0S3w2B3N0p3e0I082d/Image%202011.07.22%2011:29:25%20PM.png | |
// | |
// UIImage *buttonImage = [UIImage ipMaskedImageNamed:@"UIButtonBarAction.png" color:[UIColor redColor]]; | |
// .h | |
@interface UIImage (IPImageUtils) | |
+ (UIImage *)ipMaskedImageNamed:(NSString *)name color:(UIColor *)color; | |
@end |
