1、获取沙盒路径

 NSString *path_document=NSHomeDirectory();
//设置存储文件路径!!!!!!文件路径的名字一定要区分开
  NSString *imagePath=[path_document stringByAppendingString:[NSString stringWithFormat:@"/Documents/%@%@%@.png",_shopObj.shopPicture,_shopObj.shopColor,self.shopObj.shopName]];
//写入文件
  [UIImagePNGRepresentation(img) writeToFile:imagePath atomically:YES];
//将地址存储到自己设置的Model模型中
  self.shopObj.shopPicture=imagePath;

2、读取数据的时候,直接从自己设置文件中读取出来就行了,例子如下:

 NSString *path_document=NSHomeDirectory();
  NSString *imagePath=[path_document stringByAppendingString:[NSString stringWithFormat:@"/Documents/%@%@%@.png",_shopObj.shopPicture,_shopObj.shopColor,self.shopObj.shopName]];
  UIImage *img=[UIImage imageWithContentsOfFile:imagePath];
  cell.imgV.image=img;

  顺便说一下设置的根目录的位置:

2,获取Documents目录路径的方法:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [paths objectAtIndex:0];

3,获取Caches目录路径的方法:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cachesDir = [paths objectAtIndex:0];

4,获取tmp目录路径的方法:

NSString *tmpDir = NSTemporaryDirectory();
