Robię to w następujący sposób:

NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/MyFolder"];

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
    [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder

Nie mam wystarczającej reputacji, aby skomentować odpowiedź Manniego, ale [paths objectAtIndex :0] jest standardowym sposobem uzyskania katalogu dokumentów aplikacji

Http://developer.apple.com/library/ios/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/StandardBehaviors/StandardBehaviors.html#//apple_ref/doc/uid/TP40007072-CH4-SW6

Ponieważ NSSearchPathForDirectoriesInDomains funkcja została zaprojektowana pierwotnie dla Mac OS X, gdzie tam może być więcej niż jeden z tych katalogów, zwraca tablicę ścieżek raczej niż jedna ścieżka. W iOS, wynikowa tablica powinna zawierać pojedyncza ścieżka do katalogu. Listing 3-1 pokazuje typowe zastosowanie tego funkcja.

Listing 3-1 Getting the path to the katalog dokumentów aplikacji

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

Swift 3 Rozwiązanie:

private func createImagesFolder() {
        // path to documents directory
        let documentDirectoryPath = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first
        if let documentDirectoryPath = documentDirectoryPath {
            // create the custom folder path
            let imagesDirectoryPath = documentDirectoryPath.appending("/images")
            let fileManager = FileManager.default
            if !fileManager.fileExists(atPath: imagesDirectoryPath) {
                do {
                    try fileManager.createDirectory(atPath: imagesDirectoryPath,
                                                    withIntermediateDirectories: false,
                                                    attributes: nil)
                } catch {
                    print("Error creating images folder in documents dir: \(error)")
                }
            }
        }
    }

Nie podoba mi się "[paths objectAtIndex:0]", ponieważ jeśli Apple doda nowy folder zaczynający się od "A", "B" lub "C", folder "Documents"nie jest pierwszym folderem w katalogu.

Lepiej:

NSString *dataPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/MyFolder"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
    [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder

Swift 2 rozwiązanie:

let documentDirectoryPath: String = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first!
if !NSFileManager.defaultManager().fileExistsAtPath(documentDirectoryPath) {
        do {
            try NSFileManager.defaultManager().createDirectoryAtPath(documentDirectoryPath, withIntermediateDirectories: false, attributes: nil)

        } catch let createDirectoryError as NSError {
            print("Error with creating directory at path: \(createDirectoryError.localizedDescription)")
        }

    }

To działa dobrze dla mnie,

NSFileManager *fm = [NSFileManager defaultManager];
NSArray *appSupportDir = [fm URLsForDirectory:NSDocumentsDirectory inDomains:NSUserDomainMask];
NSURL* dirPath = [[appSupportDir objectAtIndex:0] URLByAppendingPathComponent:@"YourFolderName"];

NSError*    theError = nil; //error setting
if (![fm createDirectoryAtURL:dirPath withIntermediateDirectories:YES
                           attributes:nil error:&theError])
{
   NSLog(@"not created");
}

Poniższy kod może pomóc w tworzeniu katalogu:

-(void) createDirectory : (NSString *) dirName {

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Fetch path for document directory
dataPath = (NSMutableString *)[documentsDirectory stringByAppendingPathComponent:dirName];

NSError *error;

if (![[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]) {
    NSLog(@"Couldn't create directory error: %@", error);
}
else {
    NSLog(@"directory created!");
}

NSLog(@"dataPath : %@ ",dataPath); // Path of folder created

}

Użycie:

[self createDirectory:@"MyFolder"];

Wynik:

Katalog stworzony!

Swift 1.2 i iOS 8

Utwórz własny katalog (name = "MyCustomData") wewnątrz katalogu documents, ale tylko wtedy, gdy katalog nie istnieje.

// path to documents directory
let documentDirectoryPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first as! String

// create the custom folder path
let myCustomDataDirectoryPath = documentDirectoryPath.stringByAppendingPathComponent("/MyCustomData")

// check if directory does not exist
if NSFileManager.defaultManager().fileExistsAtPath(myCustomDataDirectoryPath) == false {

    // create the directory
    var createDirectoryError: NSError? = nil
    NSFileManager.defaultManager().createDirectoryAtPath(myCustomDataDirectoryPath, withIntermediateDirectories: false, attributes: nil, error: &createDirectoryError)

    // handle the error, you may call an exception
    if createDirectoryError != nil {
        println("Handle directory creation error...")
    }

Swift 4.0

var paths: [Any] = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
let documentsDirectory: String = paths[0] as? String ?? ""
// Get documents folder
let dataPath: String = URL(fileURLWithPath: documentsDirectory).appendingPathComponent("/MyFolder").absoluteString
if !FileManager.default.fileExists(atPath: dataPath) {
    try? FileManager.default.createDirectory(atPath: dataPath, withIntermediateDirectories: false, attributes: nil)
