iphone - MKMapView - NSUnknowKeyException -

-

I want to use with MKMapView with UITabbarController I solve any problem with other view controller applications but if I MKMapView with UITabBarController , MKMapView IBOutlet

is not coding-like code <3> IBOutlet with its code and IB throws NSUnknownKeyException > Deletes the application is running fine. If I set the MKMapView application to IBOutlet , then it throws an exception.

To change the UIViewController on TabBarController which will display your map: 

  @interface MyMapViewController {MKMapView * mapView; } @ Property (non-monomeric, intact) IBOutlet MKMapView * mapView;

Use inspector to change the MyMapViewController class from UIViewController on your tab bar controller

Does Laravel's routing work as expected? What I think, if I want to override a route, then I just have to give the expected route before each other. I have something like this: root :: group (array ('first' = & gt; 'defaultLoads' =); function () {root :: post 'Newsletter', 'newsletter controller @ store'); root: group (array ('(newsletter', 'newsletter controller');}}); That if I post this route, only http://domain.com/newsletter should run only the default loads route filter. However, when I call php Runs artisan routes , I get this: | | POST newsletter | newsletter.store | newslettercontroller@ store | default loads | login | | though it reads the route correctly (PHP artisan loads which The correct path is to the right place) but the file of the resource path even if it is not in the filter group, the path is affected. Then my question: How does it work Laravel? If so, do I post this -> Newsle...
