1、获取沙盒路径
? 1 2 3 4 5 6 7 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:
? 1 2 3 4 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:
? 1 2 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *docDir = [paths objectAtIndex:0];3,获取Caches目录路径的方法:
? 1 2 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); NSString *cachesDir = [paths objectAtIndex:0];4,获取tmp目录路径的方法:
? 1 NSString *tmpDir = NSTemporaryDirectory();感谢阅读,希望能帮助到大家,谢谢大家对本站的支持!
