Crash ERROR_CGDataProvider_BufferIsNotReadable + 12, CGDataProviderRetainBytePtr + 216
J'ai un plantage une fois toutes les 1000 à 2000 sessions dans notre application et je ne sais pas quoi faire à ce sujet.
Est-ce un Apple crash iOS où je ne peux rien faire?)
J'utilise le pod SDWebImage dans mon projet, c'est peut-être cela?
voici le journal des plantages:

@ chris-garrett m'a pointé dans la bonne direction et j'ai pu atténuer considérablement le problème en corrigeant les fuites de mémoire.
Les utilisateurs qui obtiennent maintenant cette erreur sont des personnes qui passent au moins 30 minutes sur l'application, ce qui est assez rare. En outre, le fait qu'il affecte principalement les grands écrans comme l'iPhone 7/6s/8 Plus, l'iPhone X, où davantage de mémoire est nécessaire pour rendre les images corroborerait cette théorie
Ce que vous devez faire pour résoudre ce problème est de vérifier la mémoire lors du débogage. S'il augmente progressivement en répétant les mêmes actions, il y a certainement quelque chose à corriger.
Il existe de nombreuses façons de trouver des fuites dans votre application, je ne suis pas un grand fan d'Instruments, mais vous pouvez trouver de nombreux tutoriels en ligne si nécessaire. Une autre option consiste à utiliser le graphique de la mémoire. J'ai écrit précédemment un article sur l'utilisation du graphe de mémoire ici .
Je reçois la même chose. Voici quelques informations supplémentaires.
Ce plantage se produit après que mon application capture une image, la recadre et la redimensionne.
Les informations sur le crash ont montré que l'utilisateur n'avait que 6% de mémoire disponible.
Je soupçonne que quelque chose dans mon pipeline de traitement d'image échoue silencieusement, peut-être en raison d'un manque de mémoire, puis produit un UIImage corrompu. Ensuite, lorsque j'essaie de le dessiner, il se bloque.
Dans mon cas, j'ai ajouté un tas de gardes et de déclarations de journalisation afin que, lorsque le crash se reproduise, j'espère obtenir plus d'informations et pouvoir publier une solution de contournement.
