小編給大家分享一下iOS如何生成圖片驗(yàn)證碼,相信大部分人都還不怎么了解,因此分享這篇文章給大家參考一下,希望大家閱讀完這篇文章后大有收獲,下面讓我們一起去了解一下吧!
專注于為中小企業(yè)提供網(wǎng)站建設(shè)、網(wǎng)站設(shè)計(jì)服務(wù),電腦端+手機(jī)端+微信端的三站合一,更高效的管理,為中小企業(yè)大觀免費(fèi)做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都,凝聚了一批互聯(lián)網(wǎng)行業(yè)人才,有力地推動了上1000+企業(yè)的穩(wěn)健成長,幫助中小企業(yè)通過網(wǎng)站建設(shè)實(shí)現(xiàn)規(guī)模擴(kuò)充和轉(zhuǎn)變。1.數(shù)據(jù)源
codeArray = ["0","1","2","3","4","5","6","7","8","9","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z","a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"]
2.隨機(jī)生成驗(yàn)證碼
for index in 0..<4 { let i = (Int)(arc4random()) % (codeArray.count-1) let str = codeArray[i] if index == 0 { codeStr = str as NSString }else { codeStr = "\(codeStr)\(str)" as NSString } }
3.創(chuàng)建放置驗(yàn)證碼的label
for i in 0..4.底部view是隨便畫幾條細(xì)線
for _ in 0...9 { let path = UIBezierPath.init() let pX = arc4random() % UInt32(self.frame.width) let pY = arc4random() % UInt32(self.frame.height) path.move(to: CGPoint.init(x: CGFloat(pX), y: CGFloat(pY))) let ptX = arc4random() % UInt32(self.frame.width) let ptY = arc4random() % UInt32(self.frame.height) path.addLine(to: CGPoint.init(x: CGFloat(ptX), y: CGFloat(ptY))) let layer = CAShapeLayer.init() layer.strokeColor = UIColor.getRandomColor(withAlpha: 0.2).cgColor//layer的邊框色 layer.lineWidth = 1.0 layer.strokeEnd = 1 layer.fillColor = UIColor.clear.cgColor layer.path = path.cgPath bgView.layer.addSublayer(layer) }5.調(diào)用方法及回調(diào)
public func refreshCode(callBack: @escaping (_ str: NSString) -> ()) { initCodeView() callBack(codeStr) }6.效果圖
