在我的项目中有一个打印选项,我们使用以下代码打印一个简单的pdf文件:
UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];
if (pic && [UIPrintInteractionController canPrintData: self.myPDFData] ) {
pic.delegate = self;
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.jobName = @"PrintPdf";
printInfo.duplex = UIPrintInfoDuplexLongEdge;
pic.printInfo = printInfo;
pic.showsPageRange = YES;
pic.printingItem = self.myPDFData;
void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) =
^(UIPrintInteractionController *pic, BOOL completed, NSError *error) {
if (!completed && error)
NSLog(@"FAILED! due to error in domain %@ with error code %ld",
error.domain, (long)error.code);
};
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
[pic presentFromRect:self.printButton.frame inView:self.view animated:YES completionHandler:^(UIPrintInteractionController *printInteractionController, BOOL completed, NSError *error) {
}];
} else {
[pic presentAnimated:YES completionHandler:completionHandler];
}
}
我在打印机模拟器中测试它时工作正常。我的要求是打印机可能位于同一wifi的另一个子网上。我如何使这项工作?

无需更改代码UIPrintInteractionController中的任何内容,如果打印机将位于同一网络中,则可以发现UIPrintInteractionController
,并且从弹出窗口中您可以选择打印机
