Question

录制视频时，我使用 "/MyFolder" 创建自定义文件夹，如下所示：

guard let documentsPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first else { return }
let dirPath = "\(documentsPath)/MyFolder/Videos_\(UUID().uuidString).mp4"

let outputFileURL = URL(fileURLWithPath: dirPath)
// ...

现在我有一个功能可以只删除自定义文件夹：

func deleteCustom(folder: String) {
    let fileManager = FileManager.default
    guard let documentsDirectory = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first else { return }
    let customFolder = documentsDirectory.appendingPathComponent(folder)
    guard let filePaths = try? fileManager.contentsOfDirectory(at: customFolder, includingPropertiesForKeys: nil, options: []) else { return }
    for filePath in filePaths {
        try? fileManager.removeItem(at: filePath)
    }
}

在函数参数中应该传入"MyFolder"还是"/MyFolder"？

Answer 1

In the function parameter should I pass in "MyFolder" or "/MyFolder"?

"MyFolder"，因为appendingPathComponent会自动添加/。
