Question

我正在尝试填充NSObject自定义类的数组，但是当我插入数据时收到错误：[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 Class

import Cocoa

import Parse

class FotoProduto: NSObject {

    @NSManaged var foto: PFFile?
    @NSManaged var categorias: [String]
    @NSManaged var imagemCapa: Bool

    override init() {
        super.init()
    }
}

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"
    }
}

Swift OSX - 设置值
