Get the pdf document
NSString *pathToPdfDoc = [[NSBundle mainBundle] pathForResource:@"aa" ofType:@"pdf"];
NSURL *pdfUrl = [NSURL fileURLWithPath:pathToPdfDoc];
document = CGPDFDocumentCreateWithURL((CFURLRef)pdfUrl);
currentPage = 1;
In drawRect
-(void)drawRect:(CGRect)rect
{
CGPDFPageRef page = CGPDFDocumentGetPage(document, currentPage);
CGContextRef ctx = UIGraphicsGetCurrentContext();
CGContextSaveGState(ctx);
CGContextTranslateCTM(ctx, 0.0, [self bounds].size.height);
CGContextScaleCTM(ctx, 1.0, -1.0);
CGContextConcatCTM(ctx, CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, [self bounds], 0, true));
CGContextDrawPDFPage(ctx, page);
CGContextRestoreGState(ctx);
}
