1、字符串本地化： NSLocalizedString(text, tableName: "Localizations", bundle: Bundle.main, value: "", comment: "")
2、获取当前时间： func getCurrentTime(matter: String) -> String{
let timeFormatter = DateFormatter()
timeFormatter.dateFormat = matter
return timeFormatter.string(from: Date())
}
3、获取当前时间是星期几
func getNowWeekday() -> String {
let calendar:Calendar = Calendar(identifier: .gregorian)
var comps:DateComponents = DateComponents()
comps = calendar.dateComponents([.year,.month,.day,.weekday,.hour,.minute,.second], from: Date())
let weekDay = comps.weekday! - 1
//星期
let array = ["星期日","星期一","星期二","星期三","星期四","星期五","星期六"]
return array[weekDay]
}
4、获取某一路径下所有文件并返回urls
func getAllFiles(path: URL) -> [URL] {
let contentsOfPath = try? FileManager.default.contentsOfDirectory(at:path, includingPropertiesForKeys: [URLResourceKey.isDirectoryKey], options: .skipsSubdirectoryDescendants)
let folderList = (contentsOfPath?.sorted(by: { (url1, url2) -> Bool in
let fileInfoDictionary1 = try? FileManager.default.attributesOfItem(atPath: url1.path)
let fileInfoDictionary2 = try? FileManager.default.attributesOfItem(atPath: url2.path)
let date1 = fileInfoDictionary1![FileAttributeKey.creationDate] as! Date
let date2 = fileInfoDictionary2![FileAttributeKey.creationDate] as! Date
return date1.compare(date2) == .orderedDescending
})) ?? URL
return folderList
}
5、清空某一文件夹
func removeFile(path: String){
let files = FileManager.default.subpaths(atPath:path)
for file in files ?? [] {
do {
try FileManager.default.removeItem(atPath: path + "/(file)") // 需要拼接路径！！
} catch {
print("remove item:(file)\n error:(error)")
}
}
}
\
6、删除文件夹中的某一个文件
func delete(url: URL) {
do {
try FileManager.default.removeItem(at: url)
} catch {
print(error)
}
}
