创建一个UIView的分类
import UIKit
extension UIView {
public var ld_x: CGFloat {
get {
return self.frame.origin.x
}
set(newVal) {
var ld_frame: CGRect = self.frame
ld_frame.origin.x = newVal
self.frame = ld_frame
}
}
public var ld_y: CGFloat {
get {
return self.frame.origin.y
}
set(newVal) {
var ld_frame: CGRect = self.frame
ld_frame.origin.y = newVal
self.frame = ld_frame
}
}
public var ld_width: CGFloat {
get {
return self.frame.size.width
}
set(newVal) {
var ld_frame: CGRect = self.frame
ld_frame.size.width = newVal
self.frame = ld_frame
}
}
public var ld_height: CGFloat {
get {
return self.frame.size.height
}
set(newVal) {
var ld_frame: CGRect = self.frame
ld_frame.size.height = newVal
self.frame = ld_frame
}
}
public var ld_size: CGSize {
get {
return self.frame.size
}
set(newVal) {
var ld_frame: CGRect = self.frame
ld_frame.size = newVal
self.frame = ld_frame
}
}
public var ld_centerX: CGFloat {
get {
return self.center.x
}
set(newVal) {
var ld_center: CGPoint = self.center
ld_center.x = newVal
self.center = ld_center
}
}
public var ld_centerY: CGFloat {
get {
return self.center.y
}
set(newVal) {
var ld_center: CGPoint = self.center
ld_center.y = newVal
self.center = ld_center
}
}
}
用法
let view: UIView = UIView()
view.ld_x = 10
view.ld_y = 10
