创建一个txt文件 - swift：IOS

Question

我正在尝试用快速语言创建一个txt文件。 我可以这样做吗？

我试图检查文件是否存在：4

let fileManager = NSFileManager.defaultManager()

if fileManager.fileExistsAtPath("history.txt") {
print("File exists")
} else {
print("File not found")
  //If the file doesn't exist I want to create it here
}

请你试试这个，

let someDummyTextForTextFile  = "Hi there I am the contents of text file"

let data:NSData = someDummyTextForTextFile.dataUsingEncoding(NSUTF8StringEncoding)!

let fileManage = NSFileManager.defaultManager()


if let dir : NSString = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {

    data.writeToFile("\(dir)/myFile.txt", atomically: true)
}

这将在文档目录中创建一个文本文件。或者只是试试这个，

if let dir : NSString = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.AllDomainsMask, true).first {

    do {
    try someDummyTextForTextFile.writeToFile("\(dir)/myFile.txt", atomically: true, encoding: NSUTF8StringEncoding)
}
catch _ {

    print("something went wrong")
}
}
