Nonetheless, it's a good example of how action extensions can be used to not only extend the functionality of standalone apps, but to extend the functionality of the OS as well. 7 | 8 | ### Getting Started 9 | 10 | Requires [CocoaPods](http://cocoapods.org) to manage dependencies. 11 | 12 | ``` 13 | $ cd Unzip 14 | $ pod install 15 | ``` 16 | 17 | Open **Unzip.xcworkspace**. The **Unzip** app itself doesn't contain anything, everything is implemented in **UnzipAction**. 18 | 19 | ### Icons 20 | 21 | The icons shown in the image above are from the [Glyphish 8](http://www.glyphish.com) icon set. They could not be included in this repository due to license incompatibility. 22 | 23 | ### Contact 24 | 25 | * Indragie Karunaratne 26 | * [@indragie](http://twitter.com/indragie) 27 | * [http://indragie.com](http://indragie.com) 28 | 29 | ### License 30 | 31 | Unzip is licensed under the MIT License. -------------------------------------------------------------------------------- /Unzip/Info.plist: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | CFBundleDevelopmentRegion 6 | en 7 | CFBundleExecutable 8 | $(EXECUTABLE_NAME) 9 | CFBundleIdentifier 10 | com.indragie.$(PRODUCT_NAME:rfc1034identifier) 11 | CFBundleInfoDictionaryVersion 12 | 6.0 13 | CFBundleName 14 | $(PRODUCT_NAME) 15 | CFBundlePackageType 16 | APPL 17 | CFBundleShortVersionString 18 | 1.0 19 | CFBundleSignature 20 | ???? 21 | CFBundleVersion 22 | 1 23 | LSRequiresIPhoneOS 24 | 25 | UIMainStoryboardFile 26 | Main 27 | UIRequiredDeviceCapabilities 28 | 29 | armv7 30 | 31 | UISupportedInterfaceOrientations 32 | 33 | UIInterfaceOrientationPortrait 34 | UIInterfaceOrientationLandscapeLeft 35 | UIInterfaceOrientationLandscapeRight 36 | 37 | 38 | 39 | -------------------------------------------------------------------------------- /UnzipAction/UZExtensionViewController.m: -------------------------------------------------------------------------------- 1 | // 2 | // UZExtensionViewController.m 3 | // Unzip 4 | // 5 | // Created by Indragie on 8/6/14. 6 | // Copyright (c) 2014 Indragie Karunaratne.
