如何使用IKScannerDeviceView扫描应用程序内部的文档?
How can I use IKScannerDeviceView to scan a document inside of my app?
我尝试通过IB将IKScannerDeviceView添加到我的视图中，并将其委托设置为我的应用程序委托(实现IKScannerDeviceViewDelegate)，但是当我运行该应用程序时，使用按钮 Show Details 获得了一个视图和 Scan ，并且仅启用了 Show Details ，当我单击它时，什么也没有发生.
I tried adding an IKScannerDeviceView into my view through IB and setting its delegate to my app delegate (which implements the IKScannerDeviceViewDelegate), but when I run the app I get a view with the buttons Show Details and Scan, and only Show Details is enabled and when I click it nothing happens.
我插入了扫描仪，可以通过Image Capture进行扫描，但不能通过我的应用程序进行扫描.
I have a scanner plugged in and I can scan through Image Capture, but not through my app.
有人有关于如何使用它的好教程吗?
Does anybody have a good tutorial on how to use it?
推荐答案
我终于能够弄清楚如何使用IKScannerDeviceView.
I was finally able to figure out how to use IKScannerDeviceView.
您的课程必须实现以下委托:
Your class must implement the following delegates:
IKScannerDeviceViewDelegate, ICScannerDeviceDelegate, ICDeviceBrowserDelegate
，您需要在窗口中拥有一个IKScannerDeviceView，并将其委托设置为实现 IKScannerDeviceViewDelegate
and you need to have an IKScannerDeviceView in your window, with its delegate set to the class implementing IKScannerDeviceViewDelegate
要开始使用它，您必须像这样创建一个 ICDeviceBrowser :
To start using it, you must create an ICDeviceBrowser like so:
ICDeviceBrowser *mDeviceBrowser = [[ICDeviceBrowser alloc] init];
mDeviceBrowser.delegate = self;
mDeviceBrowser.browsedDeviceTypeMask = ICDeviceLocationTypeMaskLocal|ICDeviceLocationTypeMaskRemote|ICDeviceTypeMaskScanner;
[mDeviceBrowser start];
然后以类似于以下方式的方式实现委托方法:
Then implement the delegate methods in a manner similar to this:
- (void)scannerDeviceDidBecomeAvailable:(ICScannerDevice*)scanner;
{
[scanner requestOpenSession];
}
- (void)deviceBrowser:(ICDeviceBrowser*)browser didAddDevice:(ICDevice*)addedDevice moreComing:(BOOL)moreComing
{
if ( (addedDevice.type & ICDeviceTypeMaskScanner) == ICDeviceTypeScanner )
{
[scannerView setScannerDevice:(ICScannerDevice*)addedDevice];
}
}
-(void)didRemoveDevice:(ICDevice*)removedDevice
{
[removedDevice requestCloseSession];
}
然后，如果一切顺利，则IKScannerDeviceView将能够与扫描仪进行交互！
Then if all goes right, your IKScannerDeviceView will be able to interact with your scanner!
