向mapView添加按钮并点击它会抛出EXC_BAD_ACCESS

Question

在SKMaps for iOS上，我正在尝试添加一个按钮来实现“找我”功能。该按钮在地图上正确呈现，但是当我点击它时，它会在名为IBGMethodSwizzler

的内容中抛出EXC_BAD_ACCESS错误

如果这是与SKMaps相关的任何想法吗？

在我初始化地图时，我使用此代码

let findMeButton = UIButton(frame: CGRectMake(53, 90, 44, 44))
findMeButton.setBackgroundImage(UIImage(named: "find_me"), forState: .Normal)
findMeButton.addTarget(self, action: Selector("findMe:"), forControlEvents: UIControlEvents.TouchUpInside)
self.mapView.addSubview(findMeButton)

这是findMe选择器

func findMe(sender:UIButton) {
    println("this is never called")
}

将UIButton添加为mapView的子视图是否存在已知限制？

谢谢：）

请尝试以下代码段：

var positionMeButton: UIButton = UIButton.buttonWithType(UIButtonType.System) as! UIButton 
    positionMeButton.frame = CGRectMake(10.0, CGRectGetHeight(self.view.frame) - 60.0, 100.0, 40.0) 
    positionMeButton.setTitle("Position me", forState: UIControlState.Normal) 
    positionMeButton.addTarget(self, action:"positionMe", forControlEvents: UIControlEvents.TouchUpInside) 
    positionMeButton.backgroundColor = UIColor.lightGrayColor() 
    positionMeButton.autoresizingMask = UIViewAutoresizing.FlexibleTopMargin 
    positionMeButton.titleLabel?.adjustsFontSizeToFitWidth = true 
    self.mapView.addSubview(positionMeButton); 

internal func positionMe() { 

}
