(IBAction)captureButton:(id)sender {
captureButton.hidden = YES;
cancelButton.hidden = YES;
currImage = [signatureViewController imageWithView:self.view];
NSLog (@"image %@",currImage);
imgView = [[UIImageView alloc]initWithFrame:CGRectMake(150,100,300,350)];
imgView.backgroundColor = [UIColor blackColor];
imgView.image = currImage;
[self.view addSubview:imgView];
}
imageView をキャプチャすると、最初の Controller でこれを signView に渡す必要があります。
