Delete specified file from document directory

Question

I want to delete an image from my app document directory  Code I have written to delete image is       - void removeImage  NSString   fileName       fileManager    NSFileManager defaultManager       paths   NSSearchPathForDirectoriesInDomains NSDocumentDirectory  NSUserDomainMask  YES       documentsPath    paths objectAtIndex 0       filePath    documentsPath stringByAppendingPathComponent  NSString stringWithFormat        fileName         fileManager removeItemAtPath filePath error NULL       UIAlertView  removeSuccessFulAlert   UIAlertView alloc initWithTitle   Congratulation   message   Successfully removed  delegate self cancelButtonTitle   Close  otherButtonTitles nil        removeSuccessFulAlert show       Its working partially  This code deleting file from directory  but when I m checking for the contents in directory  it still showing the image name there  I want to completely remove that file from directory  What should I change in the code to do the same  Thanks

If you are interesting in modern api way  avoiding NSSearchPath and filter files in documents directory  before deletion  you can do like   let fileManager   FileManager default let keys   URLResourceKey      nameKey   isDirectoryKey  let options  FileManager DirectoryEnumerationOptions     skipsHiddenFiles   skipsPackageDescendants  guard let documentsUrl   fileManager urls for   documentDirectory  in   userDomainMask  last        let fileEnumerator   fileManager enumerator at  documentsUrl                                                    includingPropertiesForKeys  keys                                                    options  options  else   return    let urls   URL    fileEnumerator flatMap    0 as  URL                                    filter    0 pathExtension     exe    for url in urls      do         try fileManager removeItem at  url       catch         assertionFailure    error

You can double protect your file removal with NSFileManager defaultManager   isDeletableFileAtPath PathName   As of now you MUST use do  catch   as the old error methods no longer work   isDeletableFileAtPath   is not a  throws   i e    public func removeItemAtPath path  String  throws   so it does not need the do   catch  let killFile   NSFileManager defaultManager                if  killFile isDeletableFileAtPath PathName                      do                     try killFile removeItemAtPath arrayDictionaryFilePath                                    catch let error as NSError                       error description

Instead of having the error set to NULL  have it set to   NSError  error   fileManager removeItemAtPath filePath error  amp error   if  error   NSLog        error       this will tell you if it s actually deleting the file

I  checked your code  It s working for me  Check any error you are getting using the modified code below  -  void removeImage  NSString   filename     NSFileManager  fileManager    NSFileManager defaultManager     NSString  documentsPath    NSSearchPathForDirectoriesInDomains NSDocumentDirectory  NSUserDomainMask  YES  objectAtIndex 0      NSString  filePath    documentsPath stringByAppendingPathComponent filename     NSError  error    BOOL success    fileManager removeItemAtPath filePath error  amp error     if  success          UIAlertView  removedSuccessFullyAlert     UIAlertView alloc  initWithTitle   Congratulations   message   Successfully removed  delegate self cancelButtonTitle   Close  otherButtonTitles nil          removedSuccessFullyAlert show         else           NSLog   Could not delete file -       error localizedDescription
