Exception inconnue et crash

Mon application plante quand j'essaie de faire défiler la tableview très rapide ou recharger les données à partir de la télécommande. Tout semble fonctionner très bien, quand je laisse la distance de fetch arriver en premier et ensuite, faites défiler la tableview. Je n'ai aucune idée de ce que le rapport de crash en dessous de moyens. Il fonctionne, tout simplement beaux et parfois se bloque de temps en temps.

Je serais vraiment heureux si quelqu'un pouvait m'expliquer ce qui ce crash pourraient se rapporter à et comment je pourrais le résoudre. Un grand merci à tous ceux qui sont prêts à aider les autres.

Il ressemble à une exception non interceptée. Ajouter une exception de point d'arrêt pour aider à traquer le code.
Pouvez-vous symbolicate 0x3c8df5d0 s'il vous plaît et après revenir.
Si vous vous demandez ce que trojanfoe signifie regarder ici stackoverflow.com/questions/1460892/... je n'ai gratter ma tête pendant une minute après la lecture de son commentaire, mais après avoir regardé ce lien, je sais exactement ce qu'il voulait dire. Mais oui cela aide.
Je ne suis pas sûr que ça va aider les en fait, comme il n'est pas dans le code d'application, de toute façon, c'est dans libsystem_kernel.dylib.
Le problème est que je n'ai .application fichier ni .dsym. Que puis-je faire dans cette situation ?
