Answer 1

Use like this:

BOOL isDir;
BOOL isFileExists;

isFileExists = [[NSFileManager defaultManager] fileExistsAtPath:[dirurl path] isDirectory:&isDir];
if (isDir) {...}

Official documentation example developer.apple.com:

NSArray *subpaths;
BOOL isDir;

NSArray *paths = NSSearchPathForDirectoriesInDomains
                     (NSLibraryDirectory, NSUserDomainMask, YES);

if ([paths count] == 1) {

    NSFileManager *fileManager = [[NSFileManager alloc] init];
    NSString *fontPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Fonts"];

    if ([fileManager fileExistsAtPath:fontPath isDirectory:&isDir] && isDir) {
        subpaths = [fileManager subpathsAtPath:fontPath];
// ...
[fileManager release];
