データベースとの接続を開くと、コンソールに「エラーが発生しました!:14」と表示されます。プロジェクトのリソースフォルダに「mybase.sqlite」を含め、FMDBフレームワークを使用しています。
オープンコネクトの場合、私はこのコードを使用しています:
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
FMDatabase* db = [FMDatabase databaseWithPath:@"/mybase.sqlite"];
if (![db open]) {
NSLog(@"Não abriu o banco de dados.");
[pool release];
return 0;
}
AppDelegateに、次のコードを含めました。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
*)launchOptions {
// Override point for customization after application launch. HomeViewController *homeVC = [[HomeViewController alloc] init]; navigationController = [[UINavigationController alloc] initWithRootViewController:homeVC]; [self createEditableCopyOfDatabaseIfNeeded]; [window addSubview:navigationController.view];
[window makeKeyAndVisible];
return YES; }
- (void)createEditableCopyOfDatabaseIfNeeded{ BOOL success; NSFileManager
*fileManager = [NSFileManager defaultManager]; NSError *error; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString
*documentsDirectory = [paths objectAtIndex:0]; NSString
*writableDBPath = [documentsDirectory stringByAppendingPathComponent:@"mybase.sqlite"]; success = [fileManager fileExistsAtPath:writableDBPath]; NSLog(@"Success %d", success); if (success) return; NSString
*defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"mybase.sqlite"]; success = [fileManager copyItemAtPath:defaultDBPath toPath:writableDBPath error:&error]; if (!success) { NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]); } }
