A friendly challenge to anyone w/ functional chops to improve this function. No holds barred: op overloading, enum/struct/class, everything-is-a-singleton... go for it! The only rule is no forced unwrapping (e.g. !).
import Foundation
import ImageIO
func datesFromImagesInDir(dir: String) -> [NSDate] {
let fm = NSFileManager.defaultManager()
var error: NSError?
let df = NSDateFormatter()
df.dateFormat = "yyyy:MM:dd HH:mm:ss"

rnystrom / Iphone Icon.png Bash Script
Created April 5, 2012 15:04 — forked from jessedc/iOS Icon.png bash script
A simple bash script using OSX command line tool sips to resample a 512x512px image
#!/bin/zsh
# Compatible with bash, just change "zsh" to "bash"
# First param: The folder that the original file is stored in
# Second param: The original image name
sips --resampleWidth 512 "${1}/${2}" --out "${1}/iTunesArtwork"
sips --resampleWidth 57 "${1}/${2}" --out "${1}/Icon.png"
sips --resampleWidth 114 "${1}/${2}" --out "${1}/Icon@2x.png"
sips --resampleWidth 29 "${1}/${2}" --out "${1}/Icon-Small.png"
sips --resampleWidth 58 "${1}/${2}" --out "${1}/Icon-Small@2x.png"

Small category I wrote to simplify displaying a UIImagePickerController, asking where the image should come from, and then running all the stuff. Just setup a UIImagePickerControllerDelegate and forget all of the UIActionSheet business.
// UIImagePickerController+ImageTypeActionSheet.h
@interface UIImagePickerController (ImageTypeActionSheet)
- (void)promptImagePickerTypeWithText:(NSString*)text titles:(NSArray*)titles delegate:(id <UIImagePickerControllerDelegate,UINavigationControllerDelegate>)delegate;
@end
// UIImagePickerController+ImageTypeActionSheet.m
@interface ImageTypeActionSheetDelegate : NSObject
<UIActionSheetDelegate>
