ios - Hiding ViewControllers after first launch -


In my application, I have a view controller that loads as a welcome screen. When you tap on "go", the other view controller appears that opens the user account. When information is presented, their profile appears. (This is a fun testing app) I want to make it so much that when users use registers, then their use of the profile then leaves the app, they do not have to register again. So I need help locating the app for the first time to launch, then the wellcome evaluator and the registrator should go after launch first.

WelcomeViewController: 

  - (BOOL) Application: (UIApplication *) Application was given FinishLaunchingWithOptions: (NSDictionary *) Launch Options {if ([[NSUserDefaults Standard Standard Defaults] BoolForKey: @ "Alang once"]] {ProfileViewController * profileVC = [[ProfileView controller alloc] initWithNibName: zero bundle: zero]; [Self-present ViewController: animated profileVC: not complete: zero]; } And {{NSUserDefaults Standard User Defaults] SETBOOL: Yes for Y: @ "Alang once"]; [[NSUserDefaults Standard User Defaults] Synchronize]; }}   
 Register Viewer:  
  - (BOOL) Application: (UIApplication *) Application did the FinishLaunchingWithOptions: (NSDictionary *) launchOptions {if ( [[NSUserDefaults StandardUserDefaults] BoolForKey: @ "hasLaunchedOnce"] {Profile ViewController * Profile VC = [[ProfileView Controller Alloc] initWithNibName: Zero Bundle: Zero]; [Self-present ViewController: animated profileVC: not complete: zero]; } And {{NSUserDefaults Standard User Defaults] SETBOOL: Yes for Y: @ "Alang once"]; [[NSUserDefaults Standard User Defaults] Synchronize]; }}   
 
 
 NSUserDefaults is what you are looking for ... in NSUserDefaults Check / load on logged in user and application / startup ...

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.

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...
