獲取文件屬性主要用到FileManager的實例方法attributesOfItem(atPath:)
let filePath = "xxx"
do {
let fileAttributes = try FileManager.default.attributesOfItem(atPath: filePath)
if let fileSize:NSNumber = fileAttributes[FileAttributeKey.size] as! NSNumber? {
print("File Size: \(fileSize.uint32Value)")
}
if let ownerName = fileAttributes[FileAttributeKey.ownerAccountName] {
print("File Owner: \(ownerName)")
}
if let creationDate = fileAttributes[FileAttributeKey.creationDate] {
print("File Creation Date: \(creationDate)")
}
if let modificationDate = fileAttributes[FileAttributeKey.modificationDate] {
print("File Modification Date: \(modificationDate)")
}
} catch let error as NSError {
print("Get attributes errer: \(error)")
}
發(fā)現(xiàn)以上時間為GMT時間块攒，需要轉換為本地時間。附上將轉換時區(qū)的方法佃乘，將以上方法替換為：
//將GMT時間轉換為本地時間
//獲取本地時區(qū)及與GMT的時間間隔
let timeZone = NSTimeZone.system
let interval: TimeInterval = TimeInterval(timeZone.secondsFromGMT())
if let creationDate = fileAttributes[FileAttributeKey.creationDate] {
let localCreateDate = (creationDate as! NSDate).addingTimeInterval(interval)
print("File Creation Date: \(localCreateDate)")
}
if let modificationDate = fileAttributes[FileAttributeKey.modificationDate] {
let localModDate = (modificationDate as! NSDate).addingTimeInterval(interval)
print("File Modification Date: \(localModDate)")
}
