swift - 我想要一个常量的绝对值，常量类型是CLLocationDegrees

Question

我不知道如何解决这个问题，我在晶圆厂上遇到错误:一行中的连续语句必须用 ';' 分隔

 func isUpdateLocation(currentLocation: CLLocationCoordinate2D, userLocation: CLLocationCoordinate2D)-> Bool {

    let latitude: CLLocationDegrees = currentLocation.latitude - userLocation.latitude
    let longitude: CLLocationDegrees = currentLocation.longitude - userLocation.longitude

    let absoluteValueOfLatitude ＝ fabs(latitude)// the fabs I get the error :Consecutive statements on a line must be separated by ';'
    let absoluteValueOfLongitude = fabs(longitude)

    if latitude > 0.01 || longitude > 0.01 {

        return true
    }

    return false

}

Answer 1

啊哈，问题是您输入了不同等于运算符。

// odd equal operator
let absoluteValueOfLatitude ＝ fabs(latitude)

// correct equal operator
let absoluteValueOfLatitude = fabs(latitude) 

// notice the difference with these two equal operator (＝ & =)
