How to delete ALL FILES in the specified application directory?

Question

Given the directory [[self documentsDirectory] stringByAppendingPathComponent:@"Photos/"] , how to delete ALL FILES in this folder?

(Assume the correct document catalog path)

Answer 1

 NSFileManager *fm = [NSFileManager defaultManager]; NSString *directory = [[self documentsDirectory] stringByAppendingPathComponent:@"Photos/"]; NSError *error = nil; for (NSString *file in [fm contentsOfDirectoryAtPath:directory error:&error]) { BOOL success = [fm removeItemAtPath:[NSString stringWithFormat:@"%@%@", directory, file] error:&error]; if (!success || error) { // it failed. } } 

I leave this for you to do something useful with a mistake, if it exists.

Answer 2

if you want to delete files and the directory itself, use it without for loop

 NSFileManager *fm = [NSFileManager defaultManager]; NSString *directory = [[self documentsDirectory] stringByAppendingPathComponent:@"Photos"]; NSError *error = nil; BOOL success = [fm removeItemAtPath:cacheImageDirectory error:&error]; if (!success || error) { // something went wrong } 

Answer 3

for fast lovers:

  let fm = NSFileManager.defaultManager() do { let folderPath = ... let paths = try fm.contentsOfDirectoryAtPath(folderPath) for path in paths { try fm.removeItemAtPath("\(folderPath)/\(path)") } } catch let error as NSError { print(error.localizedDescription) }
