ios - Error de ERROR_CGDataProvider_BufferIsNotReadable+12, CGDataProviderRetainBytePtr+216




objective-c iphone (2)

@ chris-garrett me señaló en la dirección correcta y pude mitigar el problema en gran medida al corregir las fugas de memoria.

Los usuarios que ahora están recibiendo este error son personas que pasan al menos 30 minutos en la aplicación, lo cual es bastante raro. Además, el hecho de que afecte a la mayoría de las pantallas grandes como iPhone 7 / 6s / 8 Plus, iPhone X, donde se necesita más memoria para renderizar las imágenes, corroboraría esa teoría.

Lo que debe hacer para resolver esto, es verificar la memoria mientras se realiza la depuración. Si aumenta gradualmente al repetir las mismas acciones, ciertamente hay algo para que lo arregles.

Hay muchas maneras de encontrar fugas en su aplicación, no soy un gran fanático de los instrumentos, pero puede encontrar muchos tutoriales en línea si es necesario. Otra opción es utilizar el gráfico de memoria. Escribí previamente un artículo sobre cómo usar el gráfico de memoria here .

Tengo un accidente una vez en cada 1000 a 2000 sesiones en nuestra aplicación y no puedo averiguar qué hacer al respecto.

¿Es eso un crash de Apple iOS donde no puedo hacer nada al respecto?

Estoy usando el pod SDWebImage en mi proyecto, tal vez sea eso?

Estoy recibiendo lo mismo. Aquí hay alguna información adicional.

Este bloqueo ocurre después de que mi aplicación capture una imagen, la recorte y la vuelva a escalar.

La información del fallo mostró que el usuario solo tenía un 6% de memoria disponible.

Sospecho que algo en mi canal de procesamiento de imágenes falla silenciosamente, posiblemente debido a que se queda sin memoria, y luego produce un UIImage corrupto. Entonces cuando intento dibujarlo se estrella.

En mi caso, agregué un montón de resguardos y declaraciones de registro para que, cuando vuelva a ocurrir el fallo, espero obtener más información y poder publicar una solución alternativa.
