我試圖從我的應用程序文檔目錄中拉出.pdf並將其加載到PIC中。 PIC顯示沒有錯誤,但在預覽中不顯示數據。 我在這裏錯過了什麼?我只是採取了一個完全錯誤的方法?如何打印應用程序文檔目錄中的.pdf文檔
-(IBAction)actPrintPDF:(id)sender
{
NSString* fileName = @"Observation.PDF";
NSArray *arrayPaths =
NSSearchPathForDirectoriesInDomains(
NSDocumentDirectory,
NSUserDomainMask,
YES);
NSString *path = [arrayPaths objectAtIndex:0];
NSString* pdfFileName = [path stringByAppendingPathComponent:fileName];
NSLog(@"Path = %@",path);
NSLog(@"pdfFileName = %@",pdfFileName);
NSData *myData = [NSData dataWithContentsOfFile:path];
UIPrintInteractionController *print = [UIPrintInteractionController sharedPrintController];
print.delegate = self;
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.jobName = [pdfFileName lastPathComponent];
printInfo.duplex = UIPrintInfoDuplexLongEdge;
print.printInfo = printInfo;
print.showsPageRange = YES;
print.printingItem = myData;
UIViewPrintFormatter *viewFormatter = [self.view viewPrintFormatter];
viewFormatter.startPage = 0;
print.printFormatter = viewFormatter;
UIPrintInteractionCompletionHandler completionHandler = ^(UIPrintInteractionController *printInteractionController, BOOL completed, NSError *error) {};
[print presentAnimated:YES completionHandler:completionHandler];
}
