CLGeocoder Swift 2版本

Question

这曾经在Swift 1.2中运行良好但现在给出错误:

"无法使用类型'的参数列表调用'geocodeAddressString'(String,completionHandler:([AnyObject]!,NSError!) - > Void)'"

geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [AnyObject]!, error: NSError!) -> Void in
            if let placemark = placemarks?[0] as? CLPlacemark {
                let annotation = MKPointAnnotation()

编辑答案:

geocoder.geocodeAddressString(address, completionHandler: {(placemarks: [CLPlacemark]?, error: NSError?) -> Void in

Answer 1

完成处理程序中的变量未正确设置,您不包含声明只是 -

coder.geocodeAddressString("1 infinite loop, cupertino, ca") { (placemarks, error) -> Void in

    if let firstPlacemark = placemarks?[0] {
        print(firstPlacemark)
    }   
}

请注意,类型推断不需要的可选强制转换将是CLPlacemark
