How to delete files which contain words in the iOS documentsDirectory

Question

I want to delete several image files in the documentsDirectory. There are already a large number of files in the documents directory, but I only want to delete the files which contain the word "Test" in their filename.

How can I go about doing this?

Answer 1

Pretty simple. Have a look at [NSFileManager contentsOfDirectoryAtPath:error:], which lists you all the files in the specified directory. Then you could filter/iterate the array according to your needs.

To delete a file use [NSFileManager removeItemAtPath:error:].
