Ios 在一个文件中获取两个数据
我想在一个文件中保存两个数据:一个图像和一个声音数据。 这对于图像(fileData)是正确的,但是我想在Parse.com中为数据声音(fileData2)添加一列。我怎么做这个?我做不到:“PFFile*file=[PFFile fileWithName:fileName-data:fileData,fileData2];” 这是我的密码:Ios 在一个文件中获取两个数据,ios,objective-c,parse-platform,pffile,Ios,Objective C,Parse Platform,Pffile,我想在一个文件中保存两个数据:一个图像和一个声音数据。 这对于图像(fileData)是正确的,但是我想在Parse.com中为数据声音(fileData2)添加一列。我怎么做这个?我做不到:“PFFile*file=[PFFile fileWithName:fileName-data:fileData,fileData2];” 这是我的密码: - (void)uploadMessage { NSData *fileData; NSData *fileData2; NSS

你不能(轻易地)把两个文件放进一个文件里。PFFFile表示一个文件
制作两个PFFile实例,一个用于图像,一个用于声音文件
PFFile *imageFile = [PFFile fileWithName:imageFileName data:imageFileData];
PFFile *soundFile = [PFFile fileWithName:soundFileName data:soundFileData];
将PFFile的这些实例设置为相应的解析列。例如:
[message setObject:imageFile forKey:@"imageFile"];
[message setObject:soundFile forKey:@"soundFile];
