生成的绑定事件MonoTouch的崩溃 [英] Generated binding events crash MonoTouch

问题描述

我有蓝牙BLE设备与绑定以下绑定：

I have a binding for Bluetooth BLE device with the following binding:

[BaseType (typeof (CBPeripheralDelegate), Delegates=new string [] {"WeakDelegate"}, 
 Events=new Type [] { typeof (BrspDelegate) })]
interface Brsp
{
    //@property (nonatomic, weak) id <BrspDelegate> delegate;
    [Export ("delegate")]
    [NullAllowed]
    BrspDelegate Delegate { get; set; }

    [Wrap ("WeakDelegate")]
    [NullAllowed]
    NSObject WeakDelegate { get; set; }

    ...other stuff

}

和以下委托：

    [BaseType(typeof(NSObject))]
    [Model]
    interface BrspDelegate 
    {
         [Abstract]
         [Export("brsp:OpenStatusChanged:"), EventArgs("OpenStatus")]

         ...other stuff
    }

当我挂钩的openstatuschanged生成的事件处理程序，它会立即崩溃的应用程序，我得到任何东西可能是错的没有反馈。我还是一个新手到绑定，所以...

When I hook up a generated event handler for the openstatuschanged, it instantly crashes the app and I get no feedback whatsoever what could be wrong. I'm still a newbie to binding, so...

我有这种感觉不知何故，我犯的错误有活动= ...的一部分，任何想法？

I have the feeling somehow I made mistake with "Events = ..." part, any ideas?

谢谢，

推荐答案

硬盘没有更多的细节（例如symbolicated崩溃日志），但您的绑定的一部分，说是反转（以及其他可能导致无限递归将崩溃您的应用程序）。

Hard to say without more details (e.g. symbolicated crash log) but part of your bindings are inverted (and that could cause endless recursion that will crash your app).

• 您代表方法应该有 [总结] 属性（在 WeakDelegate ）;和


• 您 WeakDelegate 方法应该是一个具有 [导出] 的属性代表选择。

• your Delegate method should have the [Wrap] attribute (on WeakDelegate); and
• your WeakDelegate method should be the one with the [Export] attribute on the delegate selector.

例如

    [Wrap ("WeakDelegate")]
    StronglyTypedDelegate Delegate { get; set; }

    [Export ("delegate")][NullAllowed]
    NSObject WeakDelegate { get; set; }
