objective c - Open ViewController right after viewDidLoad without .xib file -


I am working with the storyboard, as far as I know that I have not found the file what I want to do I: When the app launches, I want to see that the DB has been written in the last few days and if not, then open a scene which is not a standard view. (Because if DB is not empty then another view should be opened as it is a standard view.)

How much I have tried so far: (Deedload / ViewDeepPipper in view) < Pre> View Controller * vs. [[View Controller New]; [Self present ViewController: animated vs: yes complete: zero];

It leads to a black screen that contains nothings, it just stays black. After this I tried to do a segment but it was the result of reopening it once more.

Is there a common / standard way to do this?

Thanks a lot!

In this case, you can instantiate a UIViewController instance from the storyboard example: 

  UIStoryboard * Storyboard = [UIStoryboard storyboardWithName: @ "YourStoryboard" bundle: zero]; UIViewController * newController = [Storyboard Institutional Visual Control Manager];   
 It assumes that you are going to start with the initial view controller inside that storyboard instance.  
 You can add this with your conditional to do the following:  
  UIViewController * newViewController = Zero; If ([Self database base newinstance]) {UIStoryboard * Storyboard = [UIStoryboard storyboardWithName: @ "NewDataStoryboard" bundle: zero]; NewController = [Storyboard Institution Instrumental Weigh Controller]; } And {UIStoryboard * Storyboard = [UIStoryboard storyboardWithName: @ "NonudityStoreboard" bundle: zero]; NewController = [Storyboard Institution Instrumental Weigh Controller]; } // Current new view controller (this example is a navigation controller considers) [self.navigationController pushViewController: newController Animated: Yes];   
 If you want to instantiate the view controller which is not the initial view controller in the storyboard, you can take advantage of another example -  (id) instantiateViewControllerWithIdentifier: (NSString *)  instantiateInitialViewController     Identifier instead of calling

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
