    <p>How can i replace the database (with the one i am working on) in my app on each simulator run? (Still adding data and want to check that it looks good)</p> <p>I tried this but it doesn't seem to be working, still using the old database:</p> <pre><code>- (void)viewDidLoad { dbname = @"animaldatabase.sql"; NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDir = [documentPaths objectAtIndex:0]; dbpath = [documentsDir stringByAppendingPathComponent:dbname]; [self checkAndCreateDatabase]; [self readAnimalsFromDatabase]; [super viewDidLoad]; // Do any additional setup after loading the view. mylabel.text = [NSString stringWithFormat:@"%d", [animals count]]; } - (void) checkAndCreateDatabase{ BOOL success; NSFileManager *fileManager = [NSFileManager defaultManager]; success = [fileManager fileExistsAtPath:dbpath]; if (success) { //return; [fileManager removeItemAtPath:dbpath error:nil]; } NSString *dbPathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:dbname]; [fileManager copyItemAtPath:dbPathFromApp toPath:dbpath error:nil]; } </code></pre> <p>Also where is the location for the iphone database? When my app copies the database into the iphone, where does it end up?</p> <p><strong>UPDATE</strong></p> <p>Added the loading code as well.</p> <p>Senthilkumar:</p> <p>I fail to see how this should solve the problem? Doesn't this just skip the copying or my database if it already exists?</p> <p>What i want is to delete the database in my iphone app. Import the new database and then run it.</p>

    1. COWhen performing these file manager operations, use the `error` parameter. Create a `NSError* error;` beforehand, pass `&error` to the functions, then check it against `nil` afterwards. That should show you if there's errors, and potentially help debugging. If `error != nil`, then `[error localizedDescription]` should show you the error message.

    2. COWhere is this error shown? I can see when i alter some parameters that it gets hit and that the [error localizedDescription]; gets triggered. But where does that show up? Not in the output/error/console area.

    3. COI added a half-answer below, so that I could show a more complete code snippet.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
