Swift控制元件

CocoaPods安裝

pod 'PGBannerSwift'

使用

1、無限圖片輪播

首先引入import PGBannerSwift

let banner = PGBanner(frame: self.customView.bounds, imageNameList: ["photo1", "photo2", "photo3"], timeInterval: 3.0)
banner.delegate = self
self.view.addSubview(banner)

// MARK: - PGBannerDelegate
func selectAction(didselectAtIndex index: NSInteger, didSelectView view: Any) {
    print("index = ", index, "view = ", view)
}

2、自定義控制元件無限輪播

使用自定義控制元件輪播時，需要注意兩點

1、一定要把需要輪播的第一個view放到陣列的最後位置
2、一定要把需要輪播的最後一個view放到陣列的第一個位置

首先引入import PGBannerSwift

let view1: CustomView = Bundle.main.loadNibNamed("CustomView", owner: self, options: nil)?.first as! CustomView
view1.index = 0

let view2: CustomView = Bundle.main.loadNibNamed("CustomView", owner: self, options: nil)?.first as! CustomView
view2.index = 1

let view3: CustomView = Bundle.main.loadNibNamed("CustomView", owner: self, options: nil)?.first as! CustomView
view3.index = 2

//將最後一個view放到陣列的第一個位置
let view0: CustomView = Bundle.main.loadNibNamed("CustomView", owner: self, options: nil)?.first as! CustomView
view0.index = 2

//將第一個view放到陣列的第最後位置
let view4: CustomView = Bundle.main.loadNibNamed("CustomView", owner: self, options: nil)?.first as! CustomView
view4.index = 0

let banner = PGBanner(frame: self.customView.bounds, viewList: [view0, view1, view2, view3, view4], timeInterval: 3.0)
banner.delegate = self
self.customView.addSubview(banner)

// MARK: - PGBannerDelegate
func selectAction(didselectAtIndex index: NSInteger, didSelectView view: Any) {
    print("index = ", index, "view = ", view)
}
