ios - 以编程方式创建 plist 文件而不从我的主包中复制 plist

Question

如果不使用主包中 plist 上文件管理器实例的 .copyItemAtPath 方法，我将如何创建一个空的 plist 文件？我想检查我的 DocumentDirectory 中是否已经创建了一个 plist，如果没有创建一个空的 plist，然后创建并存储键值对以存储在 plist 中。

Answer 1

let fileManager = NSFileManager.defaultManager()

    let documentDirectory = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
    let path = documentDirectory.stringByAppendingString("/profile.plist")

    if(!fileManager.fileExistsAtPath(path)){
        print(path)

        let data : [String: String] = [
            "Company": "My Company",
            "FullName": "My Full Name",
            "FirstName": "My First Name",
            "LastName": "My Last Name",
            // any other key values
        ]

        let someData = NSDictionary(dictionary: data)
        let isWritten = someData.writeToFile(path, atomically: true)
        print("is the file created: \(isWritten)")



    }else{
        print("file exists")
    }

这对我有用。

对于 swift 3+

    let fileManager = FileManager.default

    let documentDirectory = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as String
    let path = documentDirectory.appending("/profile.plist")

    if(!fileManager.fileExists(atPath: path)){
        print(path)

        let data : [String: String] = [
            "Company": "My Company",
            "FullName": "My Full Name",
            "FirstName": "My First Name",
            "LastName": "My Last Name",
            // any other key values
        ]

        let someData = NSDictionary(dictionary: data)
        let isWritten = someData.write(toFile: path, atomically: true)
        print("is the file created: \(isWritten)")



    } else {
        print("file exists")
    }
