I’ve been looking all over the site for a similar issue, but none of the fixes for any of the other questions I’ve found have helped, so maybe I’m looking at it wrong or something. Anyways here is my code:

NSFileManager *fm = [[NSFileManager alloc] init];
NSError *err = nil;
NSURL *ASD =  [fm URLForDirectory:NSApplicationSupportDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:YES error:&err];

if (!err) {
    NSLog(@"writing file");
    NSURL* path = [NSURL URLWithString:@"license.plist" relativeToURL:ASD];
    [dict writeToURL:path atomically:NO];
    NSString* content = [NSString stringWithContentsOfURL:path encoding:NSUTF8StringEncoding error:&err];
    if (!err) {
        NSLog(@"File:%@",content);
    }
    else
    {
        NSLog(@"Error opening file: %@",err);
    }
    return YES;
}

Given that dict is a valid Dictionary(EDIT: made the incorrect assumption that even if the file was empty it would still init the Dictionary, so added an empty init even if the file is empty), I get the following log messages:

2011-09-07 15:59:58.883 iActNow[10572:707] writing file
2011-09-07 15:59:58.889 iActNow[10572:707] Error opening file: Error
Domain=NSCocoaErrorDomain Code=260 “The operation couldn’t be
completed. (Cocoa error 260.)” UserInfo=0x4ba4d0
{NSFilePath=/var/mobile/Applications/6BA775C6-29F6-4362-8860-9ADF84598531/Library/Application
Support/license.plist, NSUnderlyingError=0x497080 “The operation
couldn’t be completed. No such file or directory”}

So for whatever reason it’s not actually writing the file. Any ideas?

    I tested your code by replacing this call: 

    [dict writeToURL:path atomically:NO];

    with this one: 

    [@"Foo" writeToURL:path atomically:NO];

    and file was stored properly.

    My bet is that in dict you’re holding a custom objects that NSDictionary is not capable of writing to file by definition (i.e. by Apple specs). You’ll have to probably use a different way of storing your data to a file – maybe Archives and Serializations Programming Guide can help you?

    EDIT: I’ve just noticed that you named your file “license.plist” – check out section “Reading and Writing Property-List Data” of Property List Programming Guide
