IOS 开发获取本地图片路径及上传
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();
