You can use either the entire module or photo library exclusively.

Initialize module assembly using Paparazzo.AssemblyFactory (or Paparazzo.MarshrouteAssemblyFactory if you use Marshroute):

let factory = Paparazzo.AssemblyFactory()
let assembly = factory.mediaPickerAssembly()

Create view controller using assembly's module method:

let viewController = assembly.module(
    items: items,
    selectedItem: selectedItem,
    maxItemsCount: maxItemsCount,
    cropEnabled: true,
    cropCanvasSize: cropCanvasSize,
    routerSeed: routerSeed,    // omit this parameter if you're using AssemblyFactory
    configuration: configuration
)

Method parameters:

Additional parameters is described in protocol MediaPickerModule:

• setContinueButtonTitle(_:) and setContinueButtonEnabled(_:) allow to customize "Continue" button text and availability.
• onItemsAdd is called when user picks items from photo library or takes a new photo using camera.
• onItemUpdate is called after user performed cropping.
• onItemRemove is called when user deletes photo.
• onFinish and onCancel is called when user taps Continue and Close respectively.

When cropping photo on devices with low RAM capacity your application can crash due to memory warning. It happens because in order to perform actual cropping we need to put a bitmap of the original photo in memory. To descrease a chance of crashing on older devices (such as iPhone 4 or 4s) we can scale the source photo beforehand so that it takes up less space in memory. cropCanvasSize is used for that. It specifies the size of the photo we should be targeting when scaling.

Initialize module assembly using Paparazzo.AssemblyFactory (or Paparazzo.MarshrouteAssemblyFactory if you use Marshroute):

let factory = Paparazzo.AssemblyFactory()
let assembly = factory.photoLibraryAssembly()

Create view controller using assembly's module method:

let viewController = assembly.module(
    selectedItems: selectedItems,
    maxSelectedItemsCount: maxSelectedItemsCount,
    routerSeed: routerSeed,    // omit this parameter if you're using AssemblyFactory
    configuration: configuration
)

• selectedItems — preselected photos (or nil).
• maxItemsCount — maximum number of photos that user is allowed to pick.
• routerSeed — routerSeed provided by Marshroute.
• configuration — closure used to provide additional module setup.

You can customize colors, fonts and icons used in photo picker. Just pass an instance of PaparazzoUITheme to the initializer of assembly factory.

var theme = PaparazzoUITheme()
theme.shutterButtonColor = .blue
theme.accessDeniedTitleFont = .boldSystemFont(ofSize: 17)
theme.accessDeniedMessageFont = .systemFont(ofSize: 17)
theme.accessDeniedButtonFont = .systemFont(ofSize: 17)
theme.cameraContinueButtonTitleFont = .systemFont(ofSize: 17)
theme.cancelRotationTitleFont = .boldSystemFont(ofSize: 14)

let assemblyFactory = Paparazzo.AssemblyFactory(theme: theme)
