iOS 14 中的问题 UIDocumentPickerViewController

Question

很抱歉这个问题，但我找不到解决方案或者我无法理解...... 直到现在我都在使用这个函数。

func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
        
        
         // Importo
         if controller.documentPickerMode == .import {
          
         my code
         }

       // Esporto
         if controller.documentPickerMode == .exportToService {
          may code
         }

现在，ios 14 中的 .documentPickerMode 不再存在，我怎样才能获得相同的结果？或者他会知道我是来自进口还是出口？

现在您必须使用四种不同的方法。两个用于导出，另外两个用于打开您指定的文档类型：

---

Creates and returns a document picker that can export the types of documents you specify.

init(forExporting: [URL])

---

Creates and returns a document picker that can export or copy the types of documents you specify.

init(forExporting: [URL], asCopy: Bool)

---

Creates and returns a document picker that can open the types of documents you specify.

init(forOpeningContentTypes: [UTType])

---

Creates and returns a document picker that can open or copy the types of documents you specify.

init(forOpeningContentTypes: [UTType], asCopy: Bool)

然后在调用时切换控制器：

func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {

    switch controller {
        case documentExporter:
            print("documentExporter")
        case documentImporter:
            print("documentImporter")
        default: break
    }

}
