Invalid update: Ungültige Anzahl von Zeilen in Abschnitt 0, die mit einer nicht erfassten Ausnahme vom Typ NSException enden.
Ich habe alle dazugehörigen Beiträge gelesen und habe immer noch einen Fehler:
'Ungültige Aktualisierung: Ungültige Anzahl von Zeilen in Abschnitt 0. Die Anzahl der Zeilen in einem vorhandenen Abschnitt nach der Aktualisierung (5) muss der Anzahl der Zeilen in diesem Abschnitt vor der Aktualisierung (5) plus oder minus entsprechen die Anzahl der in diesen Abschnitt eingefügten oder gelöschten Zeilen (0 eingefügt, 1 gelöscht) und plus oder minus die Anzahl der in diesen Abschnitt eingefügten oder gelöschten Zeilen (0 eingezogen, 0 ausgezogen). '
Hier sind die Details
Ich benutze Code, um eine Klaviertabelle zu öffnen, wenn eine Zelle geöffnet ist. Es gibt Unterzellen. Jede Zeile hat eine andere Anzahl von Zellen. Es hat gut funktioniert, aber ich muss etwas modifizieren, wenn ich auf eine Zeile klicke, wird sie geöffnet, wenn ich auf eine andere Zeile klicke es um die zweite zu öffnen und die erste geöffnete Zeile zu schließen das ist mein Code rootView.m
