请建议我

谢谢

将文件保存在应用程序的文档目录中

NSString *documentsDirectoryPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *path = [documentsDirectoryPath stringByAppendingPathComponent:@"myfile.mp3"];
BOOL success = [myMp3Data writeToFile:path atomically:YES];

是的，这是可能的

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *filePath2 = [NSString stringWithFormat:@"%@/%@.jpg", documentsDirectory, fileName]; 
NSData* imageData = UIImageJPEGRepresentation(drawImage.image, 1.0); 
[imageData writeToFile:filePath2 atomically:NO];
