SBCycleScrollView是一个简单好用的图片轮播器,支持网络图片,本地图片,文字,滑动方向,storyboard以及各种样式.
使用方式
使用cocoapods导入,pod 'SBCycleScrollView','~>0.0.8',如果发现pod search SBCycleScrollView 搜索出来的不是最新版本，请先执行pod setup指令,获取最新数据源就可以了.
提供三种初始化方式
\\通过网络图片地址初始化
let cycleScrollView = CycleScrollView.initScrollView(frame: frame, imageNamesGroup: imageUrls, cycleOption: CycleOption())
\\通过本地图片名称或地址初始化
let cycleScrollView = CycleScrollView.initScrollView(frame: frame, imageNamesGroup: localImages, cycleOptions: CycleOptions())
\\通过文字数组初始化
let cycleScrollView = CycleScrollView.initScrollView(frame: frame, titleGroup: titles, cycleOption: CycleOption())
\\推荐方式,通过代理和占位图初始化,常用于图片异步获取的时候
let cycleScrollView = CycleScrollView.initScrollView(frame: frame, delegate: self, placehoder: UIImage.init(named: "place.png"), cycleOptions: CycleOptions())
cycleScrollView.imageURLStringsGroup = imageUrls
通过单独抽取一个struct来管理各种轮播器的各个属性
import UIKit
public enum PageControlStyle {
case classic,aji,aleppo,chimayo,jalapeno,jaloro,paprika,puya
}
public enum PageControlAliment {
case center,right
}
public struct CycleOption {
public var scrollDirection:UICollectionViewScrollDirection = UICollectionViewScrollDirection.horizontal
public var showPageControl: Bool = true//是否显示pageControl,默认显示
public var isOnlyDisplayText: Bool = false//只显示文字,默认false
public var imageViewMode: UIViewContentMode = UIViewContentMode.scaleToFill //图片填充样式,默认fill
public var scrollTimeInterval: TimeInterval = 2.0//滑动间隔时间
public var titleLabelBackgroundColor: UIColor = .init(red: 0, green: 0, blue: 0, alpha: 0.2)//label背景颜色
public var textColor: UIColor = .white//文字颜色
public var textFont: UIFont = UIFont.systemFont(ofSize: 14)//文字字体大小
public var titleLabelHeight: CGFloat = 30//label高度,默认30
public var textAlignment: NSTextAlignment = NSTextAlignment.left//文字默认居左
public var numberOfline = 1 // 文字行数,默认一行
public var radius: CGFloat = 5//pageControl圆点半径
public var pageAliment: PageControlAliment = PageControlAliment.center//pageControl位置,默认居中
public var bottomOffset: CGFloat = 0//pageControl距离底部距离
public var rightOffset: CGFloat = 0//pageControl距离右侧距离
public var padding: CGFloat = 7 //pagecontol间距
public var pageStyle: PageControlStyle = PageControlStyle.classic//pageControl样式,默认系统样式
public var currentPageDotColor: UIColor = .white//当前pageControl圆点的颜色
public var pageDotColor: UIColor = .gray//其他pageControl圆点的颜色
}
修改配置属性,达到你想要的效果
\\先配置再初始化
var option = CycleOption()
option.currentPageDotColor = .blue
option.radius = 10
option.pageStyle = PageControlStyle.jalapeno
let cycleScrollView = CycleScrollView.initScrollView(frame: view.frame, imageURLsGroup: imageUrls, cycleOption: option)
\\初始化后再修改配置
let cycleScrollView = CycleScrollView.initScrollView(frame: view.frame, imageURLsGroup: imageUrls, cycleOption: CycleOption())
var option = CycleOption()
option.currentPageDotColor = .blue
option.radius = 10
option.pageStyle = PageControlStyle.jalapeno
cycleScrollView.option = option
点击图片代理
代理名称SBCycleScrollViewDelegate,代理方法
func didSelectedCycleScrollView(_ cycleScrollView: CycleScrollView, _ Index: NSInteger) {
print("点击了第\(Index)张图片")
}
