解雇UIPrintInteractionController

Question

我正在使用UIPrintInteractionController从rect中呈现它.

UIPrintInteractionController *controller = [UIPrintInteractionController sharedPrintController];
// than set printing settings
...
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
    [controller presentFromRect:rect inView:view animated:YES completionHandler:completionHandler];

比我设置页数(> 1)并选择一台打印机.在设备旋转之前我打电话

[controller dismissAnimated:animated];

根据Xcode文档: You should dismiss the printing options when they are presented in a sheet or animated from a rectangle and the user changes the orientation of the device.

当我UIPrintInteractionController在旋转后出现时,打印份数被设置回1(如在初始视图中),而打印机保持选中状态.UIPrintInfo的Ivar _copies是私有的,所以我无法在旋转期间获取它并存储.

如何在旋转后恢复打印页数？

抱歉，这似乎是一个显而易见的问题，但您是否将其称为代表？

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