尝试

UIImage *image = [UIImage imageNamed:@"Image.jpg"];
NSString *stringPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0]stringByAppendingPathComponent:@"New Folder"];
// New Folder is your folder name
NSError *error = nil;
if (![[NSFileManager defaultManager] fileExistsAtPath:stringPath])
    [[NSFileManager defaultManager] createDirectoryAtPath:stringPath withIntermediateDirectories:NO attributes:nil error:&error];

NSString *fileName = [stringPath stringByAppendingFormat:@"/image.jpg"];
NSData *data = UIImageJPEGRepresentation(image, 1.0);
[data writeToFile:fileName atomically:YES];
