SDK iPhone di là delimita NSException

Question

Sto avendo un "app termina a causa di eccezione non identificata 'NSRangeException', la ragione: '*** - [NSArray objectAtIndex:]: indice 24 di là di limiti [0 .. 23]'" Non sono sicuro di come mettere il mio .m qui senza che sia davvero lunga. Per favore fatemi sapere come posso aiutare per ottenere questo problema risolto. Grazie in anticipo!

Si scopre che il problema era che le immagini sono state non tutti copiati nella cartella di destinazione> Copia Bundle Resources, e questo è ciò che stava facendo l'arresto!?!? Un milione di Grazie!

Answer 1

L'errore dice che l'array ha 24 elementi, ma si sta cercando di accedere all'elemento 25. Quindi è necessario inserire il codice che sta tentando di accedere all'elemento 25. Oppure capire perché si sta cercando di trovare l'elemento 25 in un array di 24 elementi.

EDIT:

Si consiglia di impostare un punto di interruzione nella prima riga o così di tableView: didSelectRowAtIndexPath:

poi alla gdb> digitare:

po descArray

o semplicemente:

p(int) [descArray count]

o cercare nelle variabili riquadro per vedere quanti oggetti sono in realtà in descArray in quel punto. Ripetere, se necessario, per gli altri due array.

EDIT AGAIN:

Hai un altro problema (potrebbe non essere correlato) nel nostro tableView: numberOfRowsInSection:

Si ritorna contare il ContentList tutto il tempo. Le righe dopo che il ritorno compreso il NSLogs non verrà mai raggiunto. Non appena si preme quel primo ritorno in C, si ritorna da quel metodo immediatamente. Non credo che è il tuo problema immediato, ma è un altro problema che accadrà quando si inizia ad avere di ricerca di lavoro.

Answer 2

Verificare il numero di oggetti in questi bannerImages descArray contentsList

queste matrici non aventi numero di oggetto uguale al numero di righe della vista tabella.

(è necessario verificare wher a preparare gli array poi DataSource e delegato metodi Tableview correttamente) .o inserire tutto il codice qui se non ottenere la soluzione.
