iOS开发——实用篇Swift篇QQ登入界面实现

我们知道在App Store中几乎所有软件都设计到账户的登入，而我们最常见的就是QQ，微信，在没有踏入程序员这条不归路之前，看到一个个的界面都感觉好高大上的样子。

在学习的过程中，自己就照着手机上面APP自己比较好奇的界面实现了一下，今天分享一下关于QQ登入界面，完全纯代码，实用StoryBoar太麻烦，个人比较喜欢用代码实现，而几乎所有登入界面几乎都是一样的，只是图标不同，或者还会有其他的拓展功能，不过这里都会了其他的纳豆不是事儿。

废话不多说，直接上代码

import UIKitclass ViewController: UIViewController {/// 定义属性
var QQNumber = UITextField()
var PassNumber = UITextField()override func viewDidLoad() {self.view.backgroundColor = UIColor.whiteColor()super.viewDidLoad()// 添加头图片[self .addAllSubViews()];}// 添加所有子控件func addAllSubViews(){/// 头像/var headImage = UIImageView(frame: CGRectMake(50, 30, 220, 200))headImage.image =  UIImage(named:"QQ.png")self.view.addSubview(headImage)/// QQ号输入提示// var phoneText = UILabel(frame: CGRectMake(30, 240, UIScreen.mainScreen().bounds.size.width-60, 30))// phoneText.text = "请输入QQ号"//self.view.addSubview(phoneText)/// QQ号输入框var QQNumber = UITextField(frame: CGRectMake(30, 270, UIScreen.mainScreen().bounds.size.width-60, 30))QQNumber.placeholder = "请输入QQ号"QQNumber.layer.borderWidth = 1QQNumber.layer.borderColor = UIColor.lightGrayColor().CGColorQQNumber.layer.cornerRadius = 5QQNumber.keyboardType = UIKeyboardType.NumberPadself.view.addSubview(QQNumber)self.QQNumber = QQNumber/// 密码输入提示//var passText = UILabel(frame: CGRectMake(30, 300, UIScreen.mainScreen().bounds.size.width-60, 30))//passText.text = "请输入密码"//self.view.addSubview(passText)/// 密码输入框var PassNumber = UITextField(frame: CGRectMake(30, 330, UIScreen.mainScreen().bounds.size.width-60, 30))PassNumber.placeholder = "请输入密码"PassNumber.layer.borderWidth = 1PassNumber.layer.borderColor = UIColor.lightGrayColor().CGColorPassNumber.layer.cornerRadius = 5self.view.addSubview(PassNumber)self.PassNumber = PassNumber/// 密码找回var button = UIButton(frame: CGRectMake(200, 360, 120, 30))UIButton.buttonWithType(UIButtonType.Custom)button.setTitle("忘记密码", forState: UIControlState.Normal)button.setTitleColor(UIColor.lightGrayColor(), forState: UIControlState.Normal)self.view.addSubview(button)button.addTarget(self, action: "onClick", forControlEvents: UIControlEvents.TouchUpInside)}/// 密码找回方法实现func onClick(){///找回密码提示UIAlertView(title: "温馨提示", message: "新密码已发送至手机上", delegate: nil, cancelButtonTitle: "确定", otherButtonTitles: "取消").show()}/**点击界面键盘辞去第一响应者*/override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {self.QQNumber.resignFirstResponder()self.PassNumber.resignFirstResponder()}}
