项目介绍：
ARAPointSilder有两种类型
-
normal是可以滑动的
-
point是点击的也可以滑动,但是只可以停在点出
enum ARAPointSilderType: Int {
case normal = 0
case point
} 如何使用
let silder = ARAPointSilder()
silder.bounds = CGRect(x: 0, y: 0, width: 300, height: 80)
silder.center = view.center
silder.type = .point
silder.continuous = false
silder.pointWidth = 20
silder.numberOfPoint = 4
silder.titleAttributes = [NSForegroundColorAttributeName: UIColor.red, NSFontAttributeName: UIFont(name: "HelveticaNeue", size: 18)!]
silder.titleArray = ["面议","报价","你看你","傻不傻"]
silder.addTarget(self, action: #selector(printNumber(sender:)), for: .valueChanged)
view.addSubview(silder) ARAPointSilder具有很多的属性
// MARK: - 属性
/// 滑条的类型
var type: ARAPointSilderType = .normal
/// 滑块的颜色
var thumbColor: UIColor = UIColor.white
/// 滑块的图片
var thumbImage: UIImage?
/// 滑块的大小
var thumbSize: CGSize = CGSize(width: 25, height: 25)
/// 滑块的点击范围，默认是2倍
var thumbTouchRate: CGFloat = 2.0
/// 滑块边框颜色
var thumbBordColor: UIColor = UIColor.blue
/// 类型为普通时，使用value
var value: CGFloat = 0.0 {
didSet {
if value <= minimumValue {
value = minimumValue
}
if value >= maximumValue {
value = maximumValue
}
}
}
/// 最大值
var maximumValue:CGFloat = 1.0
/// 最小值
var minimumValue:CGFloat = 0.0
/// 最大值的滑动颜色
var maximumValueTrackColor: UIColor = UIColor.cyan
/// 最小值的滑动颜色
var minimumValueTrackColor: UIColor = UIColor.red
/// 值变化是否是连续的
var continuous: Bool = true
/// 类型为点，使用index
var index: Int = 0 {
didSet {
if index >= numberOfPoint {
index = numberOfPoint - 1
} else if index < 0 {
index = 0
}
}
}
/// 点数的point数 默认是5级,最低是2级
var numberOfPoint: Int = 5 {
didSet {
if numberOfPoint < 2 {
numberOfPoint = 2
}
}
}
/// point点击范围，默认是point大小的2倍 pointTouchRate ＝ 2
var pointTouchRate: CGFloat = 2.0
/// 设置point的颜色
var pointColor: UIColor = UIColor.cyan
/// 设置Point的大小
var pointWidth: CGFloat?
/// 设置slider的左右间隔
var margin: CGFloat = 30.0
/// 滑条的颜色
var lineColor: UIColor = UIColor.gray
/// 设置滑条图片来显示
var lineImage: UIImage?
/// 设置滑条的粗细程度
var lineWidth: CGFloat = 8.0
/// 滑条y偏移量，默认是0
var sliderOffset: CGFloat = 0
/// 标题y偏移,默认是向下偏移20 正数向下，负数向上
var titleOffset: CGFloat = 20
/// 设置point的下标题
var titleArray: [String]?
/// 标题的字体
var titleFont: UIFont?
/// 所有标题的颜色
var titleColor: UIColor?
/// 每个标题的颜色
var titleColorArray: [UIColor]?
/// 文字的属性
lazy var titleAttributes: [String:AnyObject] = {
var dict = [String:AnyObject]()
// 文字颜色
dict[NSForegroundColorAttributeName] =
self.titleColor != nil
? self.titleColor
: UIColor.lightGray
// 文字大小
dict[NSFontAttributeName] =
self.titleFont != nil
? self.titleFont
: UIFont(name: "HelveticaNeue", size: 14)
return dict
}()
private var touchPoint: CGPoint = CGPoint.zero
private var thumbPoint: CGPoint = CGPoint.zero
private var thumbRect: CGRect = CGRect.zero
private var pointRectArray: [NSValue] = [NSValue]()
private var startPoint: CGFloat = 30
private var endPoint: CGFloat = 30
private var y: CGFloat = 0
private var isTap: Bool = false
private var isRun: Bool = false 我通过重写override func draw(_ rect: CGRect) {}来实现显示
这是监听方法
override func beginTracking(_ touch: UITouch, with event: UIEvent?) -> Bool {
touchPoint = touch.location(in: self)
var tempThumbRect = thumbRect
tempThumbRect.size.width = tempThumbRect.size.width * thumbTouchRate
tempThumbRect.size.height = tempThumbRect.size.height * thumbTouchRate
tempThumbRect.origin.x -= (tempThumbRect.size.width - thumbRect.size.width) / 2.0
tempThumbRect.origin.y -= (tempThumbRect.size.height - thumbRect.size.height) / 2.0
if type == .point {
isTap = true
for objc in pointRectArray {
let oldRect = objc.cgRectValue
var newRect = oldRect
newRect.size.width = newRect.size.width * pointTouchRate
newRect.size.height = newRect.size.height * pointTouchRate
newRect.origin.x -= (newRect.size.width - oldRect.size.width) / 2.0
newRect.origin.y -= (newRect.size.height - oldRect.size.height) / 2.0
if newRect.contains(touchPoint) {
thumbPoint = CGPoint(x: newRect.midX - thumbSize.width / 2.0,
y: newRect.midY - thumbSize.height / 2.0)
setNeedsDisplay()
return true
}
}
} else if type == .normal {
return tempThumbRect.contains(touchPoint)
}
return false
}
