Core Data Failing on saveToURL on UIManagedDocument
core-data, ios, objective-c, uimanageddocument
Solution
Pain is relieved, I really have to start reading my code letter for letter! I was using the `NSDocumentationDirectory` instead of the `NSDocumentDirectory`
Problem
I'm trying to set up core data but when i'm running `saveToURL` on the `UIManagedDocument` it's failing to create it. This is my code; ``` @property (nonatomic, strong) UIManagedDocument *currentUserDatabase; @synthesize currentUserDatabase = _currentUserDatabase; - (void)setCurrentUserDatabase:(UIManagedDocument *)currentUserDatabase { _currentUserDatabase = currentUserDatabase; [self useDocument]; } - (void)isUserLoggedIn { if (!self.currentUserDatabase) { NSURL *url = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentationDirectory inDomains:NSUserDomainMask] lastObject]; url = [url URLByAppendingPathComponent:@"Current User Database"]; self.currentUserDatabase = [[UIManagedDocument alloc] initWithFileURL:url]; } } - (void)useDocument { if (![[NSFileManager defaultManager] fileExistsAtPath:[self.currentUserDatabase.fileURL path]]) { [self.currentUserDatabase saveToURL:self.currentUserDatabase.fileURL forSaveOperation:UIDocumentSaveForCreating completionHandler:^(BOOL success) { if (success) { NSLog(@"create success"); } else { NSLog(@"create failed"); } //[self getCurrentUser]; }]; } else if (self.currentUserDatabase.documentState == UIDocumentStateClosed) { [self.currentUserDatabase openWithCompletionHandler:^(BOOL success) { //[self getCurrentUser]; }]; } else if (self.currentUserDatabase.documentState == UIDocumentStateNormal) { //[self getCurrentUser]; } } ``` `isUserLoggedIn` gets called first, but when it gets created, I get the log "create failed" - I don't understand because there is no errors. Are there any ways to get error messages? Anyone know why it's not working?
