我正在打印UIImage使用AirPrint,但边距不正确.这是打印时的样子:

有没有办法让它完美贴合在纸上？

这是所要求的代码:

    UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];
    //pic.delegate = del;

    UIPrintInfo *printInfo = [UIPrintInfo printInfo];
    printInfo.outputType = UIPrintInfoOutputGeneral;
    printInfo.jobName = [NSString stringWithFormat:@"New Ticket"];
    pic.printInfo = printInfo;


    pic.printingItem = [UIImage imageWithContentsOfFile:path];

    void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) =
    ^(UIPrintInteractionController *printController, BOOL completed, NSError *error) {
        if (!completed && error) {
            UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"Error." 
                                                   message:[NSString stringWithFormat:@"An error occured while printing: %@", error]
                                                  delegate:nil 
                                         cancelButtonTitle:@"OK" 
                                         otherButtonTitles:nil, nil];

            [av show];
            [av release];
        }
    };

    [pic presentAnimated:YES completionHandler:completionHandler];

在我的iOS应用程序中,我有以下代码用于AirPrinting一个简单的NSString.

#pragma mark - Print
-(IBAction)print:(id)sender {

    UIPrintInteractionController *pic = [UIPrintInteractionController sharedPrintController];
    pic.delegate = self;

    UIPrintInfo *printInfo = [UIPrintInfo printInfo];
    printInfo.outputType = UIPrintInfoOutputGeneral;
    printInfo.jobName = @"Message";
    pic.printInfo = printInfo;

    UISimpleTextPrintFormatter *textFormatter = [[UISimpleTextPrintFormatter alloc]initWithText:self.Message.text];
    textFormatter.startPage = 0;
    textFormatter.contentInsets = UIEdgeInsetsMake(72.0, 72.0, 72.0, 72.0); // 1 inch margins
    textFormatter.maximumContentWidth = 6 * 72.0;
    pic.printFormatter = textFormatter;
    pic.showsPageRange = YES;

    void (^completionHandler)(UIPrintInteractionController *, BOOL, NSError *) =
    ^(UIPrintInteractionController *printController, BOOL completed, NSError *error) {
        if (!completed && error) {
            NSLog(@"Printing could not …

我有UIPrintInteractionController的问题我发送pdf打印和使用带有ios 5的设备当我按下打印按钮将文件发送到打印机并工作.但是当我在带有ios 6的设备上测试时,我无法工作并使应用程序崩溃.

当ios 6上显示UIPrintInteractionController的视图时,这是日志:

这是我的代码:(self.myPDF是一个NMutableSData类型)

UIPrintInteractionController *controller = [UIPrintInteractionController sharedPrintController];

if  (controller && [UIPrintInteractionController canPrintData: self.myPDF] ) {



UIPrintInfo *printInfo = [UIPrintInfo printInfo];
    printInfo.outputType = UIPrintInfoOutputGeneral;
    printInfo.jobName = [NSString stringWithFormat:@"Coupon"];
    printInfo.orientation = UIPrintInfoOrientationPortrait;
printInfo.duplex = UIPrintInfoDuplexLongEdge; …

我正在开发一个使用Safari Webview的混合HTML5/iOS应用程序.我们使用AirPrint允许用户打印webview的内容.我遇到的问题是打开打印对话框后,打印样式会在屏幕上生效,即使打印完成或取消后也不会消失.这不会发生在我们的Windows或Android版本的应用程序中,它们分别使用CEF和Android System Webview.这些版本的应用程序中的打印样式仅应用于打印输出,如预期的那样.

任何人都有使用AirPrint和Safari Webview的经验,可以解释一下解决方案吗？我已经考虑过在打印之前和之后添加/删除包含CSS的链接标签,但是感觉很麻烦,并且没有回答为什么打印样式应用于屏幕的奇怪问题.

任何帮助赞赏!对不起,没有真正的方法来附加代码!

我真的遇到了这个问题.我不知道出了什么问题,但它吐了出来:

错误:尝试显示没有打印源(项目/项目/格式化程序/渲染器)的打印选项

如果我将其设置为打印png图像,而不是NSString的内容,则代码可以正常工作.

这是我的代码:

- (IBAction)pushPrint:(id)sender {
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    [dateFormatter setDateStyle:NSDateFormatterNoStyle];
    [dateFormatter setTimeStyle:NSDateFormatterLongStyle];
    [dateFormatter setDateFormat:@"dd/MM/YY     HH:mm:ss"];
    NSString* currentTime = [dateFormatter stringFromDate:[NSDate date]];
    [dateFormatter release]; 

    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

    NSString *path = [[NSBundle mainBundle] pathForResource:t[NSString stringWithFormat:@"Results Printout\n"
                                                              "\n"
                                                              "%@\n"
                                                              "\n"
                                                              "\n"
                                                              "%@", currentTime, pasteboard.string] ofType:nil];

    NSData *myData = [NSData dataWithContentsOfFile:path];
    UIPrintInteractionController *print = [UIPrintInteractionController sharedPrintController];

    print.delegate = self;
    UIPrintInfo *printInfo = [UIPrintInfo printInfo];
    printInfo.outputType = UIPrintInfoOutputGeneral;
    printInfo.jobName = [path lastPathComponent];
    printInfo.duplex = UIPrintInfoDuplexLongEdge;
    print.printInfo = printInfo; …

我有一个单例弹出窗口，因此一次只能显示一个弹出窗口。当我执行共享弹出框并选择“ AirPrint”时，共享弹出框会正确消失，并在其位置显示AirPrint弹出框。

但是，如果我再次按下共享按钮，则共享弹出窗口会显示在AirPrint弹出窗口的顶部。

我找不到引用AirPrint弹出窗口将其关闭的方法。

一些进一步的信息-我在屏幕底部的工具栏上有UIBarButtonItems，在屏幕顶部的NavigationBar的rightBarButtonItem中嵌套了四个UIBarButtonItems。

屏幕底部的UIBarButtonItems可以自动正确关闭AirPrint弹出窗口，但顶部的嵌套窗口则不会。

但是，如果我知道AirPrint弹出框的名称，则可以将其从顶部按钮的代码中删除。

尝试使用打印包含表格的html页面UIMarkupTextPrintFormatter.出于某些奇怪的原因,当第一页上有足够的空间(2-3英寸)时,最后一行被推到第二页.更糟糕的是,当我从html表中删除最后一行时,现在的最后一行(比删除的一行长几英寸)在第1页和第2页之间分开,当它在删除行之前明显适合第1页时.页眉和页脚高度都设置为零.插图也为零.当使用UIWebView并使用打印时,相同的html完全适合1页. UIViewPrintFormatter *formatter = [webview viewPrintFormatter]; 但这需要显示UIWebView(因此它被渲染),我不想这样做.

非常感谢对此的任何见解.

我正在尝试通过iPad应用程序设置打印,单击"打印"将打印包含其所有内容的视图.以下是我尝试过的内容(通过网上的几个例子汇总):

// This is the View I want to print
// Just a 200x200 blue square
var testView = UIView(frame: CGRectMake(0, 0, 200, 200))
testView.backgroundColor = UIColor.blueColor()

let printInfo = UIPrintInfo(dictionary:nil)!
printInfo.outputType = UIPrintInfoOutputType.General
printInfo.jobName = "My Print Job"

// Set up print controller
let printController = UIPrintInteractionController.sharedPrintController()
printController!.printInfo = printInfo
// This is where I was thinking the print job got the
// contents to print to the page??
printController?.printFormatter = testView.viewPrintFormatter()

// Do it
printController!.presentFromRect(self.frame, inView: self, animated: …

为了从工作线程打印到 UIPrinter（我已保存其 URL），我正在执行此操作并能够打印：

func PrintPdfDocument (pDocument:Data)
{
    // Create a print interaction controller
    let printController = UIPrintInteractionController.shared
    
    // Set the printing options
    let printInfo = UIPrintInfo(dictionary:nil)
    printInfo.jobName = "Print Job "
    printController.printInfo = printInfo
    printController.showsPageRange = true
    
    // Set the PDF document to be printed
    printController.printingItems = pDocument
    
    printController.print(to: defaulttprinter, completionHandler: { (controller, completed, error) in
        if completed {
            print("Printing successful!")
        } else {
            if let error = error {
                print("Printing failed with error: \(error.localizedDescription)")
            } else {
                print("Printing was …

我正在使用以下代码来打印包含文本和图像的HTML内容.

if (![UIPrintInteractionController isPrintingAvailable]) {
    UIAlertView *alertView = [[[UIAlertView alloc] 
        initWithTitle:NSLocalizedString(@"Printer Availability Error Title", @"")
        message:NSLocalizedString(@"Printer Availability Error Message", @"")
        delegate:nil
        cancelButtonTitle:NSLocalizedString(@"OK", @"OK")
        otherButtonTitles:nil] autorelease];
    [alertView show];
    return;
}

UIPrintInteractionController *pic = 
    [UIPrintInteractionController sharedPrintController];

if(!pic) {
    NSLog(@"Couldn't get shared UIPrintInteractionController!");
    return;
}

pic.delegate = self;

UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputGeneral;
printInfo.jobName = @"Sample";
pic.printInfo = printInfo;

NSString *htmlString = [self prepareHTMLText];
UIMarkupTextPrintFormatter *htmlFormatter =
