我對Swift很陌生，我試圖執行文件創建日期檢查。Swift3.0 fileAttributes在現有文件上拋出「沒有這樣的文件」錯誤
這個想法是檢查文件是否創建超過7天前。由於某些原因代碼總是返回「沒有這樣的文件」錯誤。
要檢查是什麼錯誤，我使用相同的路徑來讀取文件的內容在相同的功能，並完美地工作。
我錯誤地使用了路徑還是誤解了一些東西？
func creationDateCheck(name: String) -> Bool {
// This is the path I am using, file is in the favorites folder in the .documentsDirectory
let documentsUrl = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
let myFilesPath = documentsUrl.appendingPathComponent("favorites/" + name + ".xml")
let pathString = "\(myFilesPath)"
//First do block tries to get the file attributes and fails
do {
let fileAttributes = try FileManager.default.attributesOfItem(atPath: pathString)
print(fileAttributes)
let creationDate = (fileAttributes[FileAttributeKey.creationDate] as? NSDate)!
return daysBetweenDates(endDate: creationDate as Date) > 7
} catch let error as NSError {
print(error.localizedDescription)
}
// Second do block reads from file successfully using the same path
do {
print(try String(contentsOf: myFilesPath, encoding: String.Encoding.utf8))
}catch {print("***** ERROR READING FROM FILE *****")}
return false
}
