Save uiview as specified size

I have an uiimageview that is 600x600 and a uitexview loaded in a 200x200 uiview.

I would like to export this uiview to 600x600, same as the uiimageview size.

However If I use the code below I can only generate a size of 400x400, that is the retina size of the uiview.

Is there any code I can achieve this?

UIGraphicsBeginImageContextWithOptions(outputView.bounds.size, outputView.opaque, 2);
[outputView.layer renderInContext:UIGraphicsGetCurrentContext()];

UIImage *img = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

Have you tried changing the bounds of the view to what you need?

outputView.bounds = CGRectMake(0,0,600,600);
UIGraphicsBeginImageContextWithOptions(outputView.bounds.size, outputView.opaque, 2);     [outputView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
outputView.bound = ... original bounds here ...

If the internal view is set to be resized automatically, this should work seamlessly. Otherwise, you could change the frame of the internal view as well.

You could use the UIImage category of AliSoftware to resize it
