Paparazzo is a component for picking and editing photos.
| Key Features
-----------|--------------- :camera: | Taking photos using camera :iphone: | Picking photos from user's photo library :scissors: | Photo cropping and rotation
There are two options to install Paparazzo using CocoaPods.
Using Marshroute:
pod "Paparazzo"
or if you don't use Marshroute and prefer not to get it as an additional dependency:
pod "Paparazzo/Core"
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:
- items — array of photos that should be initially selected when module is presenter.
- selectedItem — selected photo. If set to
nil
or if items doesn't contain any photo with matching identifier, then the first photo in array will be selected. - maxItemsCount — maximum number of photos that user is allowed to pick.
- cropEnabled — boolean flag indicating whether user can perform photo cropping.
- cropCanvasSize — maximum size of canvas when cropping photos. (see Memory constraints when cropping).
- routerSeed — routerSeed provided by Marshroute.
- configuration — closure that allows you to provide module's additional parameters.
Additional parameters is described in protocol MediaPickerModule
:
setContinueButtonTitle(_:)
andsetContinueButtonEnabled(_:)
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
andonCancel
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)
