YangMingShan is a collection of iOS UI components that we created while building Yahoo apps. The reason we open source it is to share useful and common components with the community. Feel free to open the feature request ticket for new UI component you see on Yahoo apps or send pull-request to benefit open source community.
YangMingShan can be installed via CocoaPods. Simply add
pod 'YangMingShan'to your Podfile.
YangMingShan also supports Carthage. Simply add
github "yahoo/YangMingShan"
to your Cartfile.
The Components
YMSPhotoPicker is an UIComponent that let you select multiple photos from your albums. You can also take a photo inside YMSPhotoPicker and select it with other photos. It has the exposed theme YMSPhotoPickerTheme that you can customize several parts of YMSPhotoPicker.
Part of the code in this package was derived from Yahoo Messenger and Yahoo Taiwan Auctions.
Add NSPhotoLibraryUsageDescription and NSCameraUsageDescription to your App Info.plist to specify the reason for accessing photo library and camera. See Cocoa Keys for more details.
