Parse Pagination loadNextPage 2. Seite wird zweimal geladen ⇐ IOS

[Guest]

In meiner Parse-App habe ich die Paginierung aktiviert und zu Testzwecken die Anzahl der Objekte pro Seite auf 5 festgelegt. Wenn ich die App ausführe, wird dies in meiner TableView angezeigt

Code: Select all

1
2
3
4
5
Load More

Nachdem Sie auf „Mehr laden“ geklickt haben, sieht die gesamte Tabelle wie folgt aus:

Code: Select all

1
2
3
4
5
6
7
8
9
10
6
7
8
9
10

Wenn Sie danach auf „Mehr laden“ klicken, wird der Satz von 11-15 zweimal hinzugefügt. Was ist los?

Code: Select all
