SLPagingViewSwift 0.0.1

  • 由
  • StefanLage

一个允许进行类似 Tinder 或 Twitter 的导航栏系统。SLPagingViewSwift 是 SLPagingView Objective-C 版本的 Swift 版本

要求

  • iOS 7.0+
  • ARC

安装

手动

将 SLPagingView 文件夹导入到您的项目中。

如何使用

易于实现

    // Make views for the navigation bar
    var img1 = UIImage(named: "gear")
    img1 = img1?.imageWithRenderingMode(.AlwaysTemplate)
    var img2 = UIImage(named: "profile")
    img2 = img2?.imageWithRenderingMode(.AlwaysTemplate)
    var img3 = UIImage(named: "chat")
    img3 = img3?.imageWithRenderingMode(.AlwaysTemplate)

    var items = [UIImageView(image: img1), UIImageView(image: img2), UIImageView(image: img3)]
    var controllers = [ctr1, ctr2, ctr3]
    controller = SLPagingViewSwift(items: items, controllers: controllers, showPageControl: false)

然后您可以根据自己的需求修改行为

    // Tinder Like
    controller?.pagingViewMoving = ({ subviews in
        for v in subviews {
            var lbl = v as UIImageView
            var c = gray

            if(lbl.frame.origin.x > 45 && lbl.frame.origin.x < 145) {
                c = self.gradient(Double(lbl.frame.origin.x), topX: Double(46), bottomX: Double(144), initC: orange, goal: gray)
            }
            else if (lbl.frame.origin.x > 145 && lbl.frame.origin.x < 245) {
                c = self.gradient(Double(lbl.frame.origin.x), topX: Double(146), bottomX: Double(244), initC: gray, goal: orange)
            }
            else if(lbl.frame.origin.x == 145){
                c = orange
            }
            lbl.tintColor = c
        }
    })

其他示例

类似 Twitter 的行为

    // Twitter Like
    controller?.pagingViewMovingRedefine = ({ scrollView, subviews in
        var i = 0
        var xOffset = scrollView.contentOffset.x
        for v in subviews {
            var lbl = v as UILabel
            var alpha = CGFloat(0)

            if(lbl.frame.origin.x > 45 && lbl.frame.origin.x < 145) {
                alpha = 1.0 - (xOffset - (CGFloat(i)*320.0)) / 320.0
            }
            else if (lbl.frame.origin.x > 145 && lbl.frame.origin.x < 245) {
                alpha = (xOffset - (CGFloat(i)*320.0)) / 320.0 + 1.0
            }
            else if(lbl.frame.origin.x == 145){
                alpha = 1.0
            }
            lbl.alpha = CGFloat(alpha)
            i++
        }
    })

API

设置当前页面

如果您想要改变默认的分页控制索引（或其他任何属性），可以通过以下调用来实现：

    func setCurrentIndex(index: NSInteger, animated: Bool)

导航栏项样式

您可以通过配置导航栏项来轻松地进行自定义

    var navigationSideItemsStyle: SLNavigationSideItemsStyle

使用以下其中一个值：

    enum SLNavigationSideItemsStyle: Int {
        case SLNavigationSideItemsStyleOnBounds = 40
        case SLNavigationSideItemsStyleClose = 30
        case SLNavigationSideItemsStyleNormal = 20
        case SLNavigationSideItemsStyleFar = 10
        case SLNavigationSideItemsStyleDefault = 0
        case SLNavigationSideItemsStyleCloseToEachOne = -40
    }
