可可印刷 [英] Printing in Cocoa

问题描述

我的观点非常适合A4页面.现在我要打印它.请注意，我没有使用drawRect或类似的东西，只是一个带有子视图和文本标签的普通视图.我的问题是我在该视图上有一些视图，我使用图层来放置背景颜色和围绕项的圆角矩形.子视图不会打印，但是所有文本标签都会打印.

I have made a view that pretty much fits A4 page. Now I want to print it. Note that I am not using drawRect or anything like that, just a normal view with subviews and text labels. My problem is that I have a few views on that view which I use layers to put background colors and rounded rects around the items. The subviews don't print, but all text labels print.

_printReport只是一个带有视图和一堆文本标签的纯窗口.

The _printReport is just a plain window with a view and bunch of text labels.

我在做什么错，我该怎么做呢?我真的不想做绘画，但是如果需要的话，我会做.

What am I doing wrong and how could I do this better ? I really don't want to do a drawrect but I will if I have to.

这是某人打印时发生的代码:

Here is the code that happens when someone prints :

- (void)printWorksheet {
    TJContact *worksheet = [[self.workSheets selectedObjects] objectAtIndex:0];
    if (worksheet == nil) return;

    _printReport = [[TJPrintReportWindowController alloc] initWithWindowNibName:@"TJPrintReportWindowController"];
    [self.printReport setCompany:self.company];
    [self.printReport setContact:worksheet];

    [self.printReport showWindow:self];
    [self.printReport becomeFirstResponder];
    [self.printReport.view becomeFirstResponder];
    NSPrintInfo* printInfo = [NSPrintInfo sharedPrintInfo];

    [printInfo setHorizontalPagination:NSFitPagination];
    [printInfo setVerticalPagination:NSFitPagination];
    [printInfo setHorizontallyCentered:YES];
    [printInfo setVerticallyCentered:YES];
    [printInfo setLeftMargin:20.0];
    [printInfo setRightMargin:20.0];
    [printInfo setTopMargin:10.0];
    [printInfo setBottomMargin:10.0];

    NSPrintOperation* printOperation = [NSPrintOperation printOperationWithView:self.printReport.view printInfo:printInfo];
    [printOperation setShowsPrintPanel:YES];
    [printOperation runOperationModalForWindow:[self window] delegate:nil didRunSelector:nil contextInfo:nil];
}

不确定是否有帮助，但是主视图确实将setWantsLayers设置为YES，这是我的装饰之一:

Not sure if this helps, but the main view does have setWantsLayers to YES, and here is one of my decorations :

CALayer *customerLayer = [self.customerView layer];
[customerLayer setCornerRadius:10];
[customerLayer setBackgroundColor:[NSColor colorWithDeviceWhite:0 alpha:0.30].CGColor];
[customerLayer setBorderColor:[NSColor blackColor].CGColor];
[customerLayer setBorderWidth:1.5];

当我在屏幕上显示窗口时，看起来就像我想要的那样，但是上面的矩形无法打印，但是上面的所有标签都可以打印.

When I display the window on screen, it looks just like I want it to, but the above round rect doesn't get printed, but all labels that are on top of it do.

推荐答案

图层未出现在打印中.我必须创建自己的NSView对象并执行drawRect函数以将其作为背景视图.然后它会自动打印出来，而无需执行任何操作.

Layers don't appear on printing. I had to make my own NSView object and do a drawRect function to put as background views. Then it printed out automatically without doing anything.
