Convert UITextView into an image - ios

Question

I have a UITextView and an UIImageView that I want to convert into a single image to share.
SaveImageView, is the ImageView, where I want to save the image of the textview.
The Textview can move it across the screen, so I decide to save their final position and give it to the SaveImageView.
First convert the UItextView in an image and save his position.
Then, I want to join two imageview, into a single image.
self.SaveTextView.frame = self.textView.frame;
UIGraphicsBeginImageContext (self.textView.bounds.size);
[self.textView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *resultingImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
self.SaveTextView.image=resultingImage;
//join two uiimageview
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, NO, 0.0);
[self.BaseImageView.image drawInRect:CGRectMake(0, 0, self.BaseImageView.frame.size.width, self.BaseImageView.frame.size.height)];
[self.SaveTextView.image drawInRect:CGRectMake(self.SaveTextView.frame.origin.x, self.SaveTextView.frame.origin.y, self.SaveTextView.frame.size.width, self.SaveTextView.frame.size.height)];
_SaveImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
The problem is that the place where I write in the textview is not in the same position of the saved image, the image with the text is slightly moved, when it should be the exact spot where I have written, not find where is the error.
Any Help ??

Answer 1

Try implement this method and call it on superview:
#implementation UIView (ScreenShot)
- (UIImage *)screenShot
{
UIGraphicsBeginImageContextWithOptions(self.bounds.size, self.opaque, 0.0);
[self.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
#end

Try this...
//Make Label
UILabel *_labelTimeOutName = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 428, 32)];
_labelTimeOutName.text = #"Your label text here";
_labelTimeOutName.minimumScaleFactor = 0.5;
_labelTimeOutName.numberOfLines = 1;
_labelTimeOutName.textColor = [UIColor whiteColor];
_labelTimeOutName.backgroundColor = [UIColor clearColor];
_labelTimeOutName.font = [UIFont fontWithName:#"TrebuchetMS-Bold" size:24];
_labelTimeOutName.textAlignment = NSTextAlignmentCenter;
//add label inside a temp View
UIView *tempView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 428, 32)];
tempView.backgroundColor = [UIColor clearColor];
[tempView addSubview:_labelTimeOutName];
//render image
//CGContextRef context = UIGraphicsGetCurrentContext();
UIGraphicsBeginImageContextWithOptions(tempView.bounds.size, tempView.opaque, 0.0);
// The view to be rendered
[[tempView layer] renderInContext:UIGraphicsGetCurrentContext() ]; //context];
// Get the rendered image
