Pdf render

[Streetboy]

I am trying to render pdf in landscape using this function:

  - (void) renderPageAtIndex:(NSUInteger)index inContext:(CGContextRef)ctx {          

 CGPDFPageRef page = CGPDFDocumentGetPage(pdf, index + 1);
            
            CGContextTranslateCTM(ctx, 0, self.view.bounds.size.height);
            CGContextScaleCTM(ctx, 1.0, -1.0);
            
           // CGPDFPageRef page = CGPDFDocumentGetPage(pdf, currentPage);
            CGContextSaveGState(ctx);
            
            
            
            
            CGRect box = CGPDFPageGetBoxRect(page, kCGPDFMediaBox);
            
            CGContextScaleCTM(ctx, self.view.bounds.size.width/box.size.width, self.view.bounds.size.height/box.size.height);
            
            
            CGContextDrawPDFPage(ctx, page);
            CGContextRestoreGState(ctx);
}

But my pdf is upside down even words in pdf.

What to do if i want fix this ?

Thanks, i tried to use that code but still everything is upside down. Maybe i have to change something here:

- (CGImageRef) imageForPageIndex:(NSUInteger)pageIndex {
    NSLog(@"imageForPageIndex");
	CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
	CGContextRef context = CGBitmapContextCreate(NULL, 
												 pageSize.width, 
												 pageSize.height, 
												 8,						/* bits per component*/
												 pageSize.width * 4, 	/* bytes per row */
												 colorSpace, 
												 kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
    
	CGColorSpaceRelease(colorSpace);
	CGContextClipToRect(context, CGRectMake(0, 0, pageSize.width, pageSize.height));
	
    

    
	[dataSource renderPageAtIndex:pageIndex inContext:context];
	
	CGImageRef image = CGBitmapContextCreateImage(context);
	CGContextRelease(context);
	
	[UIImage imageWithCGImage:image];
	CGImageRelease(image);
	
	return image;
}

There i create context.

1- download the sources
2- put in and load your pdf
3- if work, see the differences line per line

have you checked the rotation?

int rotation = CGPDFPageGetRotationAngle(page);
            if (90 == rotation)
            {
                
                CGContextRotateCTM(context, 3.14/2);
}
            else if (180 == rotation)
            {
                
                CGContextRotateCTM(context, 3.14);
}
