[英]MonoTouch binding notifications in 3rd party library
我正在为IDTech CC swipers创建绑定。 我一直在反对这个问题。 我被困在如何订阅第三方库引发的事件。 具体来说,我需要知道卡片刷卡何时发生。
//Notification identifiers used with NSNotificationCenter
//physical attachment related
extern NSString * const uniMagAttachmentNotification;
extern NSString * const uniMagDetachmentNotification;
//connection related
extern NSString * const uniMagInsufficientPowerNotification;
extern NSString * const uniMagPoweringNotification;
extern NSString * const uniMagTimeoutNotification;
extern NSString * const uniMagDidConnectNotification;
extern NSString * const uniMagDidDisconnectNotification;
//swipe related
extern NSString * const uniMagSwipeNotification;
extern NSString * const uniMagTimeoutSwipeNotification;
extern NSString * const uniMagDataProcessingNotification;
extern NSString * const uniMagInvalidSwipeNotification;
extern NSString * const uniMagDidReceiveDataNotification;
//command related
extern NSString * const uniMagCmdSendingNotification;
extern NSString * const uniMagCommandTimeoutNotification;
extern NSString * const uniMagDidReceiveCmdNotification;
//misc
extern NSString * const uniMagSystemMessageNotification;
文档说这应该工作:
[Notification]
[Field ("uniMagAttachmentNotification")]
NSString uniMagAttachmentNotification { get; }
它不编译。
obj/Debug/ios/magTechBinding/uniMag.g.cs(637,95): error CS0117: `MonoTouch.Constants' does not contain a definition for `magTechBindingLibrary'
obj/Debug/ios/magTechBinding/uniMag.g.cs(637,77): error CS1502: The best overloaded method match for `MonoTouch.ObjCRuntime.Dlfcn.dlopen(string, int)' has some invalid arguments
obj/Debug/ios/magTechBinding/uniMag.g.cs(637,77): error CS1503: Argument `#1' cannot convert `object' expression to type `string'
任何想法或帮助将不胜感激!
尝试:
[Field ("uniMagAttachmentNotification", "__Internal")]
第二个参数告诉在哪个库中查找该字段。 没有一个发电机假设你将有一个恒定的准备。
现在,因为您将链接第三方静态 (.a)库,它将成为最终可执行文件的一部分。 这就是__Internal
必须用作库名的原因(它意味着查看主可执行文件内部)。
