Question

I am new programmer in objective c. I want to create “Download” directory inside the i phone(path : setting (i phone setting directory))I want to know is it possible?. I am using i phone simulator to test the program.

Another question is, How can I access created directory in i phone simulator. Below contains code I tried to create folder in i phone. But I can not access that directory by using i phone simulator. what the wrong of this code?

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

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

you can create Directory in to Document Directory as sub Folder like this way:-

-(IBAction)CreatDirInDocDir
{

    NSFileManager *filemgr = [NSFileManager defaultManager];
    NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    NSString *dir = [NSString stringWithFormat:@"%@",DirName];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:dir];

    NSError *error;

    if ([filemgr fileExistsAtPath:path ] == YES){

    }
    else
    {
        NSLog (@"File not found");

        [[NSFileManager defaultManager] createDirectoryAtPath:path withIntermediateDirectories:NO attributes:nil error:&error];
    }


}

when ever you create directory in to Document directory folder then you can get all list of Created Custom directory like this way:-

//Get all Directory

 NSFileManager *fileMan = [NSFileManager defaultManager];

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

    NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory  error:nil];

    NSLog(@"files array %@", filePathsArray);

    NSMutableArray *directoryList=[[NSMutableArray alloc]init];


    for ( NSString *direPath in filePathsArray )
    {
        NSString *path = [documentsDirectory stringByAppendingPathComponent:direPath];
        BOOL isDir = NO;
        [fileMan fileExistsAtPath:path isDirectory:(&isDir)];
        if(isDir) {
            NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:path];
            NSLog(@"log path ==%@",fullPath);
            [directoryList addObject:fullPath];
        }
    }

NSLog(@”list path ==%@”,directoryList);

Now you have array of all directory you can get any directory with index 🙂
Hope its helps you
