Swift封裝的無限輪播頭視圖

此類中代碼,是已經封裝好的,在外部創建,給其frame和父視圖,即可顯示。需要注意的地方,就是圖片哪裡了,在代碼中已經寫出來了。

就是不給demo鏈接(其實我demo沒上傳到git上),自己慢慢看代碼吧,哈哈,簡書看起來代碼,還是挺舒服的。

import UIKit

class AmonCirHeadView: UIView ,UIScrollViewDelegate{

var dataArray:NSArray?;

var _scrollView:UIScrollView?;

//計時器

var _timer:NSTimer?;

//主要是為了確定scrollview和pagecontroller的顯示位置

var index:Int64?;

var _pageControl:UIPageControl?;

override init(frame: CGRect) {

super.init(frame: frame);

//復制全部代碼 插入圖片,在此更換圖片名即可,當然也可以網絡請求圖片,這個自己去修改邏輯吧

dataArray = ["aion01.jpg","aion02.jpg","aion03.jpg"];

//創建scrollview

_scrollView = UIScrollView(frame: CGRectMake(0, 0, kScreenW,self.bounds.size.height));

_scrollView?.bouncesZoom = false;

_scrollView?.bounces = false;

_scrollView?.showsHorizontalScrollIndicator = false;

_scrollView?.showsVerticalScrollIndicator = false;

_scrollView?.pagingEnabled = true;

_scrollView?.delegate = self;

self.addSubview(_scrollView!);

_scrollView?.contentSize = CGSizeMake(self.bounds.size.width * CGFloat((dataArray?.count)!), self.bounds.size.height);

_scrollView?.backgroundColor = UIColor.redColor();

//創建pageControl

_pageControl = UIPageControl(frame: CGRectMake(0, self.bounds.size.height - 20, kScreenW, 20));

self.addSubview(_pageControl!);

_pageControl!.backgroundColor = UIColor.clearColor();

_pageControl!.numberOfPages = (dataArray?.count)!;

_pageControl!.currentPage = 0;

_pageControl!.pageIndicatorTintColor = UIColor.whiteColor();

_pageControl!.currentPageIndicatorTintColor = UIColor.orangeColor();

creatImageView();

}

required init?(coder aDecoder: NSCoder) {

fatalError("init(coder:) has not been implemented")

}

//創建scrollview上的圖片控件

func creatImageView(){

index = 0;

var i = 0;

for imgNmae in dataArray!{

let imgV = UIImageView(frame: CGRectMake(self.bounds.size.width * CGFloat(i), 0, self.bounds.size.width, self.bounds.size.height));

imgV.image = UIImage(named: imgNmae as! String);

_scrollView?.addSubview(imgV);

i = i + 1;

}

//創建計時器

_timer = NSTimer.scheduledTimerWithTimeInterval(3, target: self, selector: "timeMethod", userInfo: nil, repeats: true);

//創建runloop設置計時器的運行模式,保證在滑動界面時,計時器也在工作

NSRunLoop.currentRunLoop().addTimer(_timer!, forMode: NSRunLoopCommonModes);

}

//計時器調用的方法

func timeMethod(){

index = index!+1;

if NSInteger(index!) >= dataArray?.count{

index = 0;

}

UIView.animateWithDuration(0.35) { () -> Void in

self._scrollView!.contentOffset = CGPointMake(CGFloat(self.index!) * kScreenW, self._scrollView!.contentOffset.y);

};

_pageControl!.currentPage = NSInteger(index!);

}

//scrollview的代理

func scrollViewDidScroll(scrollView: UIScrollView) {

let x = scrollView.contentOffset.x/kScreenW;

index = Int64(x);

_pageControl!.currentPage = NSInteger(x);

}

}
