How to resize and redraw UITextView on UIScrollView zoom?

Question

I have a UIView hierarchy like this UIScrollView -> DrawingView(UIView) -> UITextView . When I zoom UIScrollView , it also scaling the UITextView causing blurred text and big font. I need the same resize frame of UITextView but it should not get blurred and at proper font.

Showing in images what i exactly need.

Before zoom my UITextView should look like :

When I zoom, its looking like this :

This is an image where I want UITextView should look like when I zoom/ or max zoom level.

Here is my code, Tried each 'TRY' code once but none works.

- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {
    return self.drawingView;
}

- (void)scrollViewDidEndZooming:(UIScrollView *)scrollView withView:(UIView *)view atScale:(float)scale
{
    // TRY 1
    self.textView.bounds = CGRectMake(0, 0, self.textView.frame.size.width*scale, self.textView.frame.size.height*scale);

    // TRY 2
    scale *= [[[scrollView window] screen] scale];
    self.textView.contentScaleFactor = scale;

    // TRY 3
    CGRect frame = self.textView.frame;
    frame.size.width = frame.size.width * scale;
    frame.size.height = frame.size.height * scale;
    self.textView.frame = frame;
    self.textView.contentScaleFactor = 1.0f;

    // TRY 4
    self.textView.transform = CGAffineTransformScale(CGAffineTransformIdentity, scale, scale);

    // TRY 5
    scaleTracker *= scale;
    [self.drawingView setTransform:CGAffineTransformIdentity];
    self.drawingView.frame = CGRectMake((int)self.drawingView.frame.origin.x,
                              (int)self.drawingView.frame.origin.y,
                              (int)(self.drawingView.frame.size.width * scaleTracker),
                              (int)(self.drawingView.frame.size.height * scaleTracker));

    NSLog(@"TextView Frame : %@",NSStringFromCGRect(self.textView.frame));
    NSLog(@"DrawingView Frame : %@",NSStringFromCGRect(self.drawingView.frame));
}

deal with UITextView zoom you can do this:

    //scale :zoomScale
    for (UIView *subView in self.txtContent.subviews) {
        subView.contentScaleFactor = scale * [UIScreen mainScreen].scale;
    }
