Mac OS: how to determine path is file or directory

Question

I have a path and I want to know, is this directory or a file. Pretty simple, but I have a problem. Here's my path:

NSString *file = @"file://localhost/Users/myUser/myFolder/TestFolder/";

or

NSString *file = @"file://localhost/Users/myUser/myFolder/my_test_file.png";

Here is my code:

BOOL isDir; // the original code from apple documentation: // if ([fileManager fileExistsAtPath:file isDirectory:&isDir] && isDir) // but even my if returns me "not ok" in log if([[NSFileManager defaultManager] fileExistsAtPath:file isDirectory:&isDir]) { NSLog(@"directory"); } else { NSLog(@"not ok"); }

files and dirs on this pathes are exists and they are ok. But I thinks problem could be in it. But I don't know why. Help me with this please.

By the way, I get path from another method:

 NSArray *contentOfMyFolder = [[NSFileManager defaultManager] contentsOfDirectoryAtURL:urlFromBookmark includingPropertiesForKeys:@[NSURLContentModificationDateKey, NSURLLocalizedNameKey] options:NSDirectoryEnumerationSkipsHiddenFiles error:nil];

after this in for loop, I get items that stored in array contentOfMyFolder and get path like this:

 for (id item in contentOfMyFolder) { NSString *path = [item absoluteString]; }

I thinks this is perfectly valid path for method fileExistsAtPath:(NSString *)path isDirectory:(BOOL)isDir

Where the problem could hide?!

The problem is here:

NSString *path = [item absoluteString];

because that creates a string representation of the URL, such as

file://localhost/Users/myUser/myFolder/TestFolder/

and that is not what fileExistsAtPath: expects. What you need is the path method to convert the URL to a path:

for (NSURL *item in contentOfMyFolder) { NSString *path = [item path]; BOOL isDir; if ([[NSFileManager defaultManager] fileExistsAtPath:path isDirectory:&isDir]) { if (isDir) { NSLog(@"%@ is a directory", path); } else { NSLog(@"%@ is a file", path); } } else { NSLog(@"Oops, %@ does not exist?", path); } }

Alternatively, you can ask the URL for its "directory property":

for (NSURL *item in contentOfMyFolder) { NSNumber *isDir; NSError *error; if ([item getResourceValue:&isDir forKey:NSURLIsDirectoryKey error:&error]) { if ([isDir boolValue]) { NSLog(@"%@ is a directory", item); } else { NSLog(@"%@ is a file", item); } } else { NSLog(@"error: %@", error); } }
