hat den Erreichbarkeitstest von Apple kopiert, aber der Linker gibt einen Fehler aus

Question

Ich habe versucht, das von Apple veröffentlichte Erreichbarkeitsprojekt zu verwenden, um eine Erreichbarkeit in einem eigenen Beispiel zu erkennen. i kopiert die meisten Initialisierung, aber ich bekomme diesen Fehler in den Linker:

vergessen. Ich wusste einfach nicht, dass ich das Systemkonfigurations-Framework manuell hinzufügen muss. Ich dachte, es würde hinzugefügt werden, wenn es importiert wurde.
