如何在不使用主捆绑中plist文件管理器实例的.copyItemAtPath方法的情况下创建空plist文件?我想检查是否已经在我的DocumentDirectory中创建了一个plist,如果没有创建一个空plist,然后创建并存储键值对以存储在plist中。

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。

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")
}
