i recently got a iOS NSMallocException crash which is Out of memory. We suggest restarting the application. If you have an unsaved document, create a backup copy in Finder, then try to save.

and it crashed at

[cell.touxiangImageView sd_setImageWithURL:[NSURL URLWithString:kSmallImageUrl(self.user.image_url)]];

kSmallImageUrl just for getting a right URL of the user avatar

#define kSmallImageUrl(url) ([url hasPrefix:@"http"]) ? url : [NSString stringWithFormat:@"%@%@?x-oss-process=image/resize,w_200,h_200",FALO_CDN_URL,url]

And the used memory we caught on the third party SDK shows the memory not really high when crashed like around 150MB

I guess its not a memory leak but might be memory suddenly increases in a short time.

I would appreciate if you have any idea about why this crash happened.
