移动文件并覆盖 [英] Move file and override

问题描述

即使文件已经存在，我仍在尝试移动文件.

I'm trying to move a file even if a file with the same name already exists.

NSFileManager().moveItemAtURL(location1, toURL: location2)

NSFileManager的方法moveItemAtURL是否具有覆盖选项?如何替换现有文件?

Does NSFileManager's method moveItemAtURL have an override option? How can I replace the existing file?

推荐答案

您始终可以检查文件是否存在于目标位置. 如果是这样，请将其删除并移动您的项目.

You can always check if the file exists in the target location. if it does, delete it and move your item.

Swift 2.3

let filemgr = NSFileManager.defaultManager()

if !filemgr.fileExistsAtPath(location2) 
{
  do
  {
    try filemgr.moveItemAtURL(location1, toURL: location2)
  }
  catch
  {
  }
}
else
{
  do
  {
    try filemgr.removeItemAtPath(location2)
    try filemgr.moveItemAtURL(location1, toURL: location2)
  }
  catch
  {

  }
}

快速3 +

try? FileManager.default.removeItem(at: location2)
try FileManager.default.copyItem(at: location1, to: location2)
