iPhoneで1秒間に何枚のスクリーンショットを撮れるか知りたいです。現在、5つのスクリーンショットを取得しています。これが私のコードです

- (void)viewDidLoad
{
    [super viewDidLoad];
    [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(saveImageInPhotoAlbum) userInfo:nil repeats:YES];
    // Do any additional setup after loading the view, typically from a nib.
}

    -(void)saveImageInPhotoAlbum
{
    UIGraphicsBeginImageContext(CGSizeMake(self.view.frame.size.width,self.view.frame.size.height));

    CGContextRef context = UIGraphicsGetCurrentContext();
    [self.view.layer renderInContext:context];
    UIImage *screenShot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();


    NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(screenShot)];

    UIImage *image=[UIImage imageWithData:imageData];
    UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);

}
