Value of type '(CGRect) -> CGRect' has no member 'maxY' Value of type '(CGRect) -> CGRect' has no member 'maxX' Value of type '(CGRect) -> CGRect' has no member 'width' Value of type '(CGRect) -> CGRect' has no member 'height' Value of type '(CGRect) -> CGRect' has no member 'size'
是由於你定義的某個變量屬性不對,多半應該是 CGFloat
,而你沒有規定變量類型,系統默認識別成了 Int
或者 Double
類型swift
let frameWidth = 300 // 識別爲 Int // 改成 let frameWidth: CGFloat = 300
