- Implement FMPhotoPickerViewControllerDelegate protocol to handle selected photos.
func fmPhotoPickerController(_ picker: FMPhotoPickerViewController, didFinishPickingPhotoWith photos: [UIImage])
func fmPhotoPickerController(_ picker: FMPhotoPickerViewController, didFinishPickingPhotoWith assets: [PHAsset])
If you prefer to receive selected photos in type of PHAsset
instead of UIImage
then don't forget to set the shouldReturnAsset
to true
and implement the corresponding delegation method.

You can freely create your own filter by implementing the FMFilterable
protocol.
public protocol FMFilterable {
func filter(image: UIImage) -> UIImage
func filterName() -> String
}
Be careful that the filterName is used to determine whether the two filters are the same.
Make sure that your filter's names are not duplicated, especially with the default filters that you want to use.
Similar as filter function, FMPhotoPicker provides the capability to use your own cropping by implementing the FMCroppable
protocol.
public protocol FMCroppable {
func crop(image: UIImage, toRect rect: CGRect) -> UIImage
func name(string: [String: String]) -> String
func icon() -> UIImage
func ratio() -> FMCropRatio?
}
The func name(strings: [String: String]) -> String
will receive the strings configuration from configuration object.
It allows you customize the cropping while keeping all your language setting in only one place.
The name()
method is also used as identifier for the cropping.
Thus, make sure you do not have any duplicate of the cropping name.
You can use your own view style for the confirmation view by implementing the FMAlertable
protocol.
public protocol FMAlertable {
func show(in viewController: UIViewController, ok: @escaping () -> Void, cancel: @escaping () -> Void)
}
