Grand code mais j'ai un peu de mal à travailler dans mon projet. Il obtient tout l'URL est correctement mais quand je clique dessus rien ne se passe. Voici mon code, j'ai dû modifier le vôtre légèrement à travailler avec mon projet). Est qu'il manque quelque chose:
- (void) renderPageAtIndex:(NSUInteger)index inContext:(CGContextRef)ctx {
//CGPDFPageRef page = CGPDFDocumentGetPage(pdf, index+1);
CGPDFPageRef page = CGPDFDocumentGetPage(pdf, index+1);
CGAffineTransform transform1 = aspectFit(CGPDFPageGetBoxRect(page, kCGPDFMediaBox),
CGContextGetClipBoundingBox(ctx));
CGContextConcatCTM(ctx, transform1);
CGContextDrawPDFPage(ctx, page);
int pageCount = CGPDFDocumentGetNumberOfPages(pdf);
int i = 0;
while (i<pageCount) {
i++;
CGPDFPageRef page = CGPDFDocumentGetPage(pdf, i+1);
CGPDFDictionaryRef pageDictionary = CGPDFPageGetDictionary(page);
CGPDFArrayRef outputArray;
if(!CGPDFDictionaryGetArray(pageDictionary, "Annots", &outputArray)) {
return;
}
int arrayCount = CGPDFArrayGetCount( outputArray );
if(!arrayCount) {
continue;
}
for( int j = 0; j < arrayCount; ++j ) {
CGPDFObjectRef aDictObj;
if(!CGPDFArrayGetObject(outputArray, j, &aDictObj)) {
return;
}
CGPDFDictionaryRef annotDict;
if(!CGPDFObjectGetValue(aDictObj, kCGPDFObjectTypeDictionary, &annotDict)) {
return;
}
CGPDFDictionaryRef aDict;
if(!CGPDFDictionaryGetDictionary(annotDict, "A", &aDict)) {
return;
}
CGPDFStringRef uriStringRef;
if(!CGPDFDictionaryGetString(aDict, "URI", &uriStringRef)) {
return;
}
CGPDFArrayRef rectArray;
if(!CGPDFDictionaryGetArray(annotDict, "Rect", &rectArray)) {
return;
}
int arrayCount = CGPDFArrayGetCount( rectArray );
CGPDFReal coords[4];
for( int k = 0; k < arrayCount; ++k ) {
CGPDFObjectRef rectObj;
if(!CGPDFArrayGetObject(rectArray, k, &rectObj)) {
return;
}
CGPDFReal coord;
if(!CGPDFObjectGetValue(rectObj, kCGPDFObjectTypeReal, &coord)) {
return;
}
coords[k] = coord;
}
char *uriString = (char *)CGPDFStringGetBytePtr(uriStringRef);
NSString *uri = [NSString stringWithCString:uriString encoding:NSUTF8StringEncoding];
CGRect rect = CGRectMake(coords[0],coords[1],coords[2],coords[3]);
CGPDFInteger pageRotate = 0;
CGPDFDictionaryGetInteger( pageDictionary, "Rotate", &pageRotate );
CGRect pageRect = CGRectIntegral( CGPDFPageGetBoxRect( page, kCGPDFMediaBox ));
if( pageRotate == 90 || pageRotate == 270 ) {
CGFloat temp = pageRect.size.width;
pageRect.size.width = pageRect.size.height;
pageRect.size.height = temp;
}
rect.size.width -= rect.origin.x;
rect.size.height -= rect.origin.y;
CGAffineTransform trans = CGAffineTransformIdentity;
trans = CGAffineTransformTranslate(trans, 0, pageRect.size.height);
trans = CGAffineTransformScale(trans, 1.0, -1.0);
rect = CGRectApplyAffineTransform(rect, trans);
// do whatever you need with the coordinates.
// e.g. you could create a button and put it on top of your page
// and use it to open the URL with UIApplication's openURL
NSURL *url = [NSURL URLWithString:uri];
NSLog(@"URL: %@", url);
CGPDFContextSetURLForRect(ctx, (CFURLRef)url, rect);
// CFRelease(url);
}
}
}
Grâce à l'excellent travail BrainFeeder!
Mise à JOUR:
Pour toute personne utilisant les feuilles de projet dans votre application, ce est la façon dont j'ai obtenu le lien PDF pour travailler (ce n'est pas parfait comme le rect semble remplir la totalité de l'écran, mais c'est un début):
- (void) renderPageAtIndex:(NSUInteger)index inContext:(CGContextRef)ctx {
CGPDFPageRef page = CGPDFDocumentGetPage(pdf, index+1);
CGAffineTransform transform1 = aspectFit(CGPDFPageGetBoxRect(page, kCGPDFMediaBox),
CGContextGetClipBoundingBox(ctx));
CGContextConcatCTM(ctx, transform1);
CGContextDrawPDFPage(ctx, page);
CGPDFPageRef pageAd = CGPDFDocumentGetPage(pdf, index);
CGPDFDictionaryRef pageDictionary = CGPDFPageGetDictionary(pageAd);
CGPDFArrayRef outputArray;
if(!CGPDFDictionaryGetArray(pageDictionary, "Annots", &outputArray)) {
return;
}
int arrayCount = CGPDFArrayGetCount( outputArray );
if(!arrayCount) {
//continue;
}
for( int j = 0; j < arrayCount; ++j ) {
CGPDFObjectRef aDictObj;
if(!CGPDFArrayGetObject(outputArray, j, &aDictObj)) {
return;
}
CGPDFDictionaryRef annotDict;
if(!CGPDFObjectGetValue(aDictObj, kCGPDFObjectTypeDictionary, &annotDict)) {
return;
}
CGPDFDictionaryRef aDict;
if(!CGPDFDictionaryGetDictionary(annotDict, "A", &aDict)) {
return;
}
CGPDFStringRef uriStringRef;
if(!CGPDFDictionaryGetString(aDict, "URI", &uriStringRef)) {

if( pageRotate == 90 || pageRotate == 270 ) {
CGFloat temp = pageRect.size.width;

}
rect.size.width -= rect.origin.x;
rect.size.height -= rect.origin.y;
CGAffineTransform trans = CGAffineTransformIdentity;
trans = CGAffineTransformTranslate(trans, 0, pageRect.size.height);
trans = CGAffineTransformScale(trans, 1.0, -1.0);
rect = CGRectApplyAffineTransform(rect, trans);
// do whatever you need with the coordinates.
// e.g. you could create a button and put it on top of your page
// and use it to open the URL with UIApplication's openURL
NSURL *url = [NSURL URLWithString:uri];
NSLog(@"URL: %@", url);
// CGPDFContextSetURLForRect(ctx, (CFURLRef)url, rect);
UIButton *button = [[UIButton alloc] initWithFrame:rect];
[button setTitle:@"LINK" forState:UIControlStateNormal];
[button addTarget:self action:@selector(openLink:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
// CFRelease(url);
}
//}
Dernière Mise À Jour
Ci-dessous est le dernier code que j'ai utilisé dans mes applications.
