[英]How to create a pdf from two UIViews with 2 pages
我有兩個UIView
需要轉換為PDF並作為附件發送。 我的代碼重疊了第一個UIView
。 我想將此作為電子郵件的附件發送。
謝謝。
NSMutableData *pdfData=[NSMutableData data];
UIGraphicsBeginPDFContextToData(pdfData,aView.bounds, nil);
CGContextRef pdfContext=UIGraphicsGetCurrentContext();
UIGraphicsBeginPDFPage();
[aView.layer renderInContext:pdfContext];
UIGraphicsEndPDFContext();
UIGraphicsBeginPDFContextToData(pdfData, bView.bounds, nil);
CGContextRef pdfContext2=UIGraphicsGetCurrentContext();
UIGraphicsBeginPDFPage();
[bView.layer renderInContext:pdfContext2];
UIGraphicsEndPDFContext();
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
NSString *subject=[NSString stringWithFormat:@"Delivery Report-%@",[globUserID uppercaseString]];
[mailer setSubject:subject];
[mailer addAttachmentData:pdfData mimeType:@"pdf" fileName:@"DeliveryReport.pdf"];
[self presentModalViewController:mailer animated:YES];
不要創建第二個上下文。
NSMutableData *pdfData=[NSMutableData data];
CGRect bounds = CGRectMake(0, 0, 612, 792); // letter sized paper, adjust as needed
UIGraphicsBeginPDFContextToData(pdfData, bounds, nil);
CGContextRef pdfContext = UIGraphicsGetCurrentContext();
UIGraphicsBeginPDFPage();
[aView.layer renderInContext:pdfContext];
UIGraphicsBeginPDFPage();
[bView.layer renderInContext:pdfContext];
UIGraphicsEndPDFContext();
