我附加了一个文件到我使用此代码的邮件中。在iPhone或iPad上打印PDF文件
[mail addAttachmentData:[myView PDFData] mimeType:@"application/pdf" fileName:@"name.pdf"];
我怎样才能做到同样的事，打印文件，我需要把它打印[MyView的PDFData。
我发现只有这个打印：
NSString *PDFFileWithName = [[NSBundle mainBundle] pathForResource:@"name" ofType:@"pdf"];
NSData *dataFromPath = [NSData dataWithContentsOfFile:PDFFileWithName];
感谢
你应该通过阅读Drawing and Printing Guide for iOS。 UIPrintInteractionController的printingItem属性可以设置为PDF的NSData。
更新添加的代码
dataFromPath的价值应该等于[MyView的PDFData]虽然我将建议改变变量名，一旦你得到它的工作。
NSData *dataFromPath = [myView PDFData];
提前发布错误的链接 - 这应该有帮助！

我知道这个教程很棒，但我找不到我需要的东西。 – Marco 2011-03-26 13:22:30
写下面的代码，并检查它
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *pathFolder = [NSString stringWithFormat:@"%@",pdfFileName];
NSString *path = [[paths objectAtIndex:0] stringByAppendingPathComponent:pathFolder];
NSURL *targetURL = [NSURL fileURLWithPath:path];
UIPrintInteractionController *pc = [UIPrintInteractionController sharedPrintController];
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.orientation = UIPrintInfoOrientationPortrait;
printInfo.jobName [email protected]“Print”;
printInfo.duplex = UIPrintInfoDuplexLongEdge;
pc.printInfo = printInfo;
pc.showsPageRange = YES;
pc.printingItem = targetURL;
UIPrintInteractionCompletionHandler completionHandler =
^(UIPrintInteractionController *printController, BOOL completed,
NSError *error) {
if(!completed && error){
NSLog(@"Print failed - domain: %@ error code %ld", error.domain, (long)error.code);
}
};
[pc presentFromRect:shareButton.frame inView:self.view animated:YES completionHandler:completionHandler];
你可以用说明扩展你的答案吗？为什么这段代码能解决问题？没有描述的代码转储很少有助于未来的读者。 – 2016-02-24 11:54:33
的完整代码打印PDF
UIPrintInteractionController *pc = [UIPrintInteractionController
sharedPrintController];
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.orientation = UIPrintInfoOrientationPortrait;
printInfo.jobName [email protected]"Report";
pc.printInfo = printInfo;
pc.showsPageRange = YES;
pc.printingItem = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://test.com/Print_for_Client_Name.pdf"]];
// You can use here image or any data type to print.
UIPrintInteractionCompletionHandler completionHandler =
^(UIPrintInteractionController *printController, BOOL completed,
NSError *error) {
if(!completed && error){
NSLog(@"Print failed - domain: %@ error code %ld", error.domain,
(long)error.code);
}
};
[pc presentFromRect:CGRectMake(0, 0, 300, 300) inView:self.view animated:YES completionHandler:completionHandler];
这些都是我使用电子邮件的代码（它的工作原理很大）和代码用于需要更改的打印 – Marco 2011-03-26 13:23:42
我已经更新了我的答案，如果您愿意，可以在您的帖子的编辑中重新发布您的代码示例。 – Joe 2011-03-28 18:22:38
我用这段代码做了，实际上很简单..感谢大家：printController.printingItem = [myView PDFData]; – Marco 2011-03-29 00:00:32
