Print PDF file on iphone or ipad
提问by Marco
I attached a file to the mail I am using this code.
我在使用此代码的邮件中附加了一个文件。
[mail addAttachmentData:[myView PDFData] mimeType:@"application/pdf" fileName:@"name.pdf"];
How can I do the same thing for printing a file, I need to print this [myView PDFData].
我如何为打印文件做同样的事情，我需要打印这个 [myView PDFData]。
I found only this for printing:
我发现只有这个用于打印：
NSString *PDFFileWithName = [[NSBundle mainBundle] pathForResource:@"name" ofType:@"pdf"];
NSData *dataFromPath = [NSData dataWithContentsOfFile:PDFFileWithName];
Thanks
谢谢

You should read through the Drawing and Printing Guide for iOS. The printingItemproperty of UIPrintInteractionControllercan be set to the NSDataof a PDF.
您应该通读iOS的绘图和打印指南。的printingItem属性UIPrintInteractionController可以设置为NSDataPDF的属性。
Update for added code
更新添加的代码
The value of dataFromPath should be equal to [myView PDFData] although I would recommend changing the variable name once you get it working.
dataFromPath 的值应该等于 [myView PDFData] 虽然我会建议您在使用后更改变量名称。
NSData *dataFromPath = [myView PDFData];
