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_documentstringByAppendingString:[NSStringstringWithFormat:@"/Documents/%@%@%@.png",_shopObj.shopPicture,_shopObj.shopColor,self.shopObj.shopName]]; //写入文件 [UIImagePNGRepresentation(img)writeToFile:imagePathatomically: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_documentstringByAppendingString:[NSStringstringWithFormat:@"/Documents/%@%@%@.png",_shopObj.shopPicture,_shopObj.shopColor,self.shopObj.shopName]]; UIImage*img=[UIImageimageWithContentsOfFile: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=[pathsobjectAtIndex:0];
3,获取Caches目录路径的方法:
NSArray*paths=NSSearchPathForDirectoriesInDomains(NSCachesDirectory,NSUserDomainMask,YES); NSString*cachesDir=[pathsobjectAtIndex:0];
4,获取tmp目录路径的方法:
NSString*tmpDir=NSTemporaryDirectory();
