Hello Christian

The basics are very simple:
- (NSData *)pdfDataForView:(UIView *)myView inRect:(CGRect)bounds {
// set up PDF rendering context
NSMutableData *pdfData = [NSMutableData data];
UIGraphicsBeginPDFContextToData(pdfData, bounds, nil);
UIGraphicsBeginPDFPage();
// tell our view to draw
[myView drawRect:bounds];
// remove PDF rendering context
UIGraphicsEndPDFContext();
return pdfData;
}
If you need to do a multipage document, it will get more complicated.
HTH,
