是否可以使用Kotlin/Native观察iOS NSObject值的变化

import kotlinx.cinterop.ObjCClass
import kotlinx.cinterop.ObjCName
import kotlinx.cinterop.ObjCObjectVar
import platform.Foundation.NSObject
import platform.Foundation.addObserver
import platform.Foundation.observeValueForKeyPath

@ObjCName("MyObserver")
class MyObserver : NSObject() {
    override fun observeValueForKeyPath(keyPath: String?, ofObject: ObjCObjectVar<*>, change: Map<Any?, *>?, context: CPointer<out kotlin.Any?>?) {
        // 处理属性值变化
    }
}

@ObjCName("MyObject")
class MyObject : NSObject() {
    @ObjCName("observedProperty")
    var observedProperty: String? = null
        set(value) {
            field = value
            // 属性值变化时，通知观察者
            this.notifyChangeForKeyPath("observedProperty")
        }
}

fun main() {
    val observer = MyObserver()
    val myObject = MyObject()

    myObject.addObserver(observer, "observedProperty", null, null)
    myObject.observedProperty = "New Value"
}
