How to create an image from a UIView / UIScrollView
I've managed to get it.
Here's my solution, based on a few different ones from the web:
- (UIImage *)imageByCropping:(UIScrollView *)imageToCrop toRect:(CGRect)rect{ CGSize pageSize = rect.size; UIGraphicsBeginImageContext(pageSize); CGContextRef resizedContext = UIGraphicsGetCurrentContext(); CGContextTranslateCTM(resizedContext, -imageToCrop.contentOffset.x, -imageToCrop.contentOffset.y); [imageToCrop.layer renderInContext:resizedContext]; UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return image;}which you call by using:
CGRect clippedRect = CGRectMake(0, 0, 320, 300);picture.image = [self imageByCropping:myScrollView toRect:clippedRect];
