1.自定义引导页控制器
import UIKit
let kScreenWidth = UIScreen.main.bounds.size.width
let kScreenHeight = UIScreen.main.bounds.size.height
letkHighlighted =UIColor.init(red:230/255.0, green:230/255.0, blue:230/255.0, alpha:1.0)

,UICollectionViewDataSource,
UICollectionViewDelegateFlowLayout{
//分区数
funcnumberOfSectionsInCollectionView(collectionView:UICollectionView) ->Int{
return1;
}
//每个分区含有的 item 个数
funccollectionView(_collectionView:UICollectionView, numberOfItemsInSection section:Int) ->Int{
return self.imageListCount!;
}
//每个分区的内边距
funccollectionView(_collectionView:UICollectionView, layout collectionViewLayout:UICollectionViewLayout, insetForSectionAt section:Int) ->UIEdgeInsets{
returnUIEdgeInsetsMake(0,0,0,0);
}
//最小 item 间距
funccollectionView(_collectionView:UICollectionView, layout collectionViewLayout:UICollectionViewLayout, minimumInteritemSpacingForSectionAt section:Int) ->CGFloat{
return0;
}
//最小行间距
funccollectionView(_collectionView:UICollectionView, layout collectionViewLayout:UICollectionViewLayout, minimumLineSpacingForSectionAt section:Int) ->CGFloat{
return0;
}
//item 的尺寸
funccollectionView(_collectionView:UICollectionView, layout collectionViewLayout:UICollectionViewLayout, sizeForItemAt indexPath:IndexPath) ->CGSize{
returnCGSize.init(width: collectionView.frame.size.width, height: collectionView.frame.size.height)
}
funccollectionView(_collectionView:UICollectionView, cellForItemAt indexPath:IndexPath) ->UICollectionViewCell{
letcell = collectionView.dequeueReusableCell(withReuseIdentifier:pageControlCellId, for: indexPath)as!PageControlCollectionViewCell;
cell.imageV?.image=UIImage(named:self.imageList![indexPath.row]as!String)
returncell
}

}
funcsetupUI(){

collectionView!.backgroundColor = .white

}
else
{
cancelBtn?.isHidden=true
}
}
requiredinit?(coder aDecoder:NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
2.自定义引导页控制器cell
import UIKit
classPageControlCollectionViewCell:UICollectionViewCell{
varimageV :UIImageView?
overrideinit(frame:CGRect) {
super.init(frame: frame);
imageV=UIImageView(frame:CGRect.init(x:0, y:0, width:self.frame.size.width, height:self.frame.size.height))
self.addSubview(imageV!);
}
requiredinit?(coder aDecoder:NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
3.在使用的地方调用即可
import UIKit
classViewController:UIViewController{
varsaveImageList = [String]()
varimageList :[String] = ["image1","image2","image3"]
overridefuncviewDidLoad() {
super.viewDidLoad()
CCPageControlSwift.SetupPageControlView(imagesList:imageList, block: { (pageNum)in
print("第\(pageNum+1)页")
}) {
print("点击了Button")
}
// Do any additional setup after loading the view, typically from a nib.
}
overridefuncdidReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
