从imageview打印图像：xcode

Question

任何人都可以告诉我如何使用UIPrintInteractionController从imageview打印图像。 谢谢

Answer 1

将图像转换为pdf并打印PDF。 https://github.com/kharrison/CodeExamples/blob/master/AirPrinter/AirPrinter

您需要添加文件UYLGenericPrintPageRenderer.h和UYLGenericPrintPageRenderer.m

从这里得到它：

约AirPrinter以及如何

Answer 2

首先读it.Follow链接使用：

https://github.com/kharrison/CodeExamples/blob/master/AirPrinter/AirPrinter/UYLGenericPrintPageRenderer.h

https://github.com/kharrison/CodeExamples/blob/master/AirPrinter/AirPrinter/UYLGenericPrintPageRenderer.m

这些是PrintPageRenderer文件。

导入此文件在你的类：

#import "UYLGenericPrintPageRenderer.h" 

现在检查您的设备支持的打印与否：

if ([UIPrintInteractionController isPrintingAvailable]) { 

    UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(printImageView)]; 
    [self.navigationItem setRightBarButtonItem:barButton animated:NO]; 
    self.printButton = barButton; 
    [barButton release]; 

} 
else { 
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Sorry, Printing is not available" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil]; 
    [alert show]; 
    [alert release]; 
} 

现在打印的是“printImageView”这里作为对象的图像的UIImageView类。

- (void)printImageView{ 

UIPrintInteractionController *pc = [UIPrintInteractionController sharedPrintController]; 

UIPrintInfo *printInfo = [UIPrintInfo printInfo]; 
printInfo.outputType = UIPrintInfoOutputGeneral; 
printInfo.jobName = @"Sample Print"; 
pc.printInfo = printInfo; 
pc.showsPageRange = YES; 

UYLGenericPrintPageRenderer *renderer = [[UYLGenericPrintPageRenderer alloc] init]; 
renderer.headerText = printInfo.jobName; 
renderer.footerText = @"AirPrinter Sample"; 

UIViewPrintFormatter *formatter = [printImageView viewPrintFormatter]; 
[renderer addPrintFormatter:formatter startingAtPageAtIndex:0]; 
pc.printPageRenderer = renderer; 
[renderer release]; 

UIPrintInteractionCompletionHandler completionHandler = 
^(UIPrintInteractionController *printController, BOOL completed, NSError *error) { 
    if(!completed && error){ 
     DLog(@"Print failed - domain: %@ error code %u", error.domain, error.code); 
    } 
}; 

    [pc presentFromBarButtonItem:self.printButton animated:YES completionHandler:completionHandler]; 
}
