本文介绍了如何解决:无法将"CLLocationDegrees"类型的值(也称为"Double")分配为"Float!"类型在Swift 3中的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我从Google地图上获得了一个坐标,我想将其分配给一个float变量,但是它显示了此错误:
I get a coordinate from my google map and I want to assign it to a float variable, but it shows this error:
无法将类型"CLLocationDegrees"(也称为"Double")的值分配给类型 '漂浮!'
Cannot assign value of type 'CLLocationDegrees' (aka 'Double') to type 'Float!'
func markerButtonClicked(sender:MapButton) {
let coord = self.getCenterCoordinate()
let addressObj = Address()
addressObj.latitude = coord.latitude
addressObj.longitude = coord.longitude
}
func getCenterCoordinate() -> (CLLocationCoordinate2D) {
let location = CGPoint(x:self.mView.bounds.size.width/2,y:self.mView.bounds.size.height/2)
let coord = self.mView.projection .coordinate(for: location)
return coord
}
class Address: NSObject {
var latitude:Float!
var longitude:Float!
}
推荐答案
将您的值转换为浮点,然后赋值
Convert your value to float and then assign
addressObj.latitude = Float(coord.latitude)
addressObj.longitude = Float(coord.longitude)
