Swift在设置值时发送给NSObject子类上的实例的不可识别的选择器
我试图填充一个NSObject自定义类数组，但是当我插入数据时，我收到了一个错误：[Wood_Factory___Gerenciador.FotoProduto setFoto:]: unrecognized selector sent to instance 0x6080000055a0
调用类的操作。
@IBAction func selecionarFotosButtonClicked(_ sender: NSButton) {
let panel = NSOpenPanel()
panel.canChooseFiles = true
panel.canChooseDirectories = false
panel.allowsMultipleSelection = true
panel.canCreateDirectories = false
panel.allowedFileTypes = NSImage.imageTypes
panel.beginSheetModal(for: view.window!) { (result) in
if result.rawValue == NSFileHandlingPanelOKButton {
for url in panel.urls {
let fotoNSImage = NSImage(byReferencing: url)
let fotoNSImageRedim = Ferramentas.redimensionaNSImage(imagem: fotoNSImage, tamanho: NSSize(width: 200, height: 200))
let fotoNSImageRep = NSBitmapImageRep(data: (fotoNSImageRedim.tiffRepresentation)!)
let fotoNSImagePng = fotoNSImageRep?.representation(using: NSBitmapImageRep.FileType.png, properties: [:])
//let fotoProduto = FotoProduto(foto: PFFile(data: fotoNSImagePng!)!, categorias: [])
let fotoProduto = FotoProduto()
fotoProduto.foto = PFFile(data: fotoNSImagePng!)
fotoProduto.categorias = []
fotoProduto.imagemCapa = false
self.projeto?.fotos = [FotoProduto]()
self.projeto?.fotos.append(fotoProduto)
}
self.verificaCapaDefinida()
if !self.capaDefinida {
let indiceImagem = IndexPath(item: 0, section: 0)
self.definirImagemCapa(indice: indiceImagem, limparSelecao: true)
} else {
self.fotosProjetoCollectionView.deselectAll(self)
self.fotosProjetoCollectionView.reloadData()
}
}
}
}FotoProduto类
import Cocoa
import Parse
class FotoProduto: NSObject {
@NSManaged var foto: PFFile?
@NSManaged var categorias: [String]
@NSManaged var imagemCapa: Bool
override init() {
super.init()
}
}以下是完全错误：

解决方案是创建PFObject的子类。
import Cocoa
import Parse
class FotoProduto: PFObject, PFSubclassing {
@NSManaged var foto: PFFile?
@NSManaged var categorias: [String]
@NSManaged var imagemCapa: Bool
override init() {
super.init()
}
init(foto: PFFile, categorias: [String]) {
super.init()
self.foto = foto
self.categorias = categorias
self.imagemCapa = false
}
static func parseClassName() -> String {
return "FotoProduto"
}
