好的.所以问题来了.

我想通过带谷歌标记的prepareForSegue func 传递一个类.怎么做?

There is a class i want to pass with prepareForSegue func with google marker. How to do it?

推荐答案

你太接近了，不能简单地使用你的数组对象设置passedMarker.

You are too close to pass simply set the passedMarker with your array object.

if let marker = sender as? GMSMarker , //is it correct do declare marker as GMSMarker?
   let dict = marker.userData as? [String:Int] {

    let markerIndex = dict["index"]!
    nextVC.passedMarker = self.markers[markerIndex]
}

现在只需访问 VC3 的 viewDidLoad 中的 passedMarker 属性.

Now simply access passedMarker property in viewDidLoad of VC3.
