Thread 1: EXC_BAD_INSTRUCTION (Code = EXC_1386_INVOP, SUBCODE = 0X0) - Fehler

Question

Ich benutze eine KontaktPicker-Funktion, um aus Kontakten auszuwählen und sie zu meiner erstellten Tabellenansicht hinzuzufügen. Wenn ich jedoch meine App starte und auf den gewünschten Kontakt klicke, stürzt meine App ab. Das Problem scheint die Funktion contactPicker (CNContactPickerViewController, didSelect ...) zu sein. Obwohl wenn ich die schnelle Datei anzeigen, keine Fehler angezeigt werden. Kann jemand helfen, das Problem zu lösen?

Answer 1

Sie deklarieren delegate wie diese var delegate: ViewTwo! aber man kann nie Wert zuweisen. Wenn Sie also delegate.didFetchContacts([contacts]) anrufen, ist die delegatenil und Ihre App wird abstürzen. (Es scheint, Sie möchten delegate = self irgendwo in der viewDidLoad hinzufügen).

---

Sie müssen Ihre viewDidLoad Methode richtig schreiben. Verschiebe es, um sicherzustellen, dass es keine innere Funktion ist.

override func viewDidLoad() {}
