POShare A High Resolution Image

Body
copied!<p>Here's my code:</p> <pre><code> - (void)shareButtonTapped { CGSize newImageSize = CGSizeMake(850.0, 850.0); UIGraphicsBeginImageContextWithOptions(newImageSize, YES, _aImageView.image.scale); [self.aImageView.layer renderInContext:UIGraphicsGetCurrentContext()]; [self.aImageView.image drawInRect:CGRectMake(0, 0, newImageSize.width, newImageSize.height)]; UIImage * image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); // UIActivityViewController code here } </code></pre> <p>Right now if I tap on the Mail button, for example, the image is the newImageSize, but my _aImageView.image is only displayed in the top left corner while the rest of the image is solid black.</p> <p>How do I edit this code to scale the image to the 850 x 850 or to a high resolution size so it will look sharp when shared via Email or Social Media?</p> <p>Thanks! </p> <p>EDIT <strong>*</strong></p> <p>Still stuck. I feel like I am almost there.</p> <p>Here's my new code:</p> <pre><code> - (void)shareButtonTapped { _topBarImageView.hidden = YES; _bottomBarImageView.hidden = YES; CGSize newImageSize = CGSizeMake(600.0, 600.0); UIGraphicsBeginImageContextWithOptions(newImageSize, YES, _aImageView.image.scale); [_aImageView.layer = renderInContext:UIGraphicsGetCurrentContext()]; [_aLabel drawTextInRect:CGRectMake(20, 250, 280, 140)]; UIImage * image = UIGraphicsGetImageFromCurrentImageContext(); UIImage * newImage = [UIImage imageWithImage:image scaledToSize:newImageSize]; UIGraphicsEndImageContext(); _topBarImageView.hidden = NO; _bottomBarImageView.hidden = NO; // Share Code } </code></pre> <p>So I'm hiding a couple of custom imageViews that are on this screen. The only thing I want shared is the aImageView and the aLabel.</p> <p>Right now when I open my email for example, I can see the newImageSize, but the majority of the box is still black. I still can't figure out what I am missing. </p>
