I do that the following way:
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

I don't have enough reputation to comment on Manni's answer, but [paths objectAtIndex:0] is the standard way of getting the application's Documents Directory

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

Swift 3 Solution:
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)")
}
}
}
}

I don't like "[paths objectAtIndex:0]" because if Apple adds a new folder starting with "A", "B" oder "C", the "Documents"-folder isn't the first folder in the directory.
Better:
NSString *dataPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/MyFolder"];
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder

The Swift 2 solution:
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)")
}
}

This works fine for me,
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");
}

Swift 4.0
let paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
// Get documents folder
let documentsDirectory: String = paths.first ?? ""
// Get your folder path
let dataPath = documentsDirectory + "/yourFolderName"
if !FileManager.default.fileExists(atPath: dataPath) {
// Creates that folder if not exists
try? FileManager.default.createDirectory(atPath: dataPath, withIntermediateDirectories: false, attributes: nil)
}

Following code may help in creating directory :
-(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
}
Usage :
[self createDirectory:@"MyFolder"];
Result :
directory created!
dataPath : /var/mobile/Applications/BD4B5566-1F11-4723-B54C-F1D0B23CBC/Documents/MyFolder

Swift 1.2 and iOS 8
Create custom directory (name = "MyCustomData") inside the documents directory but only if the directory does not exist.
// 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...")
}
}
