macOS Is a directory

[Miglu]

I am trying to save an array:

-(IBAction)save:(id)sender{
	NSSavePanel* savePanel = [NSSavePanel savePanel];
	if (NSFileHandlingPanelCancelButton != [savePanel runModal]) {
		NSURL* url = [savePanel directoryURL];
		NSFileManager* manager = [NSFileManager defaultManager];
		if(![manager createFileAtPath:[url path] contents:[NSData dataWithBytes:array length:sizeof(*array)] attributes:nil]){
			NSLog(@"Error was code: %d - message: %s", errno, strerror(errno));

		}
	}
}

This is logged: "Error was code: 21 - message: Is a directory." What is the problem?

Your path is pointing to a directory instead of a file?

But is createFileAtPath not supposed to create a file inside a directory?

What is the name of the file you are trying to create?

Read the docs. What do you think will happen if you ask it to create a file where a directory already exists?

Alright, the path has to end in the file's name.
