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*不是事儿。
废话不多说,直接上代码
import UIKit class 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(, , , )) 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(, , UIScreen.mainScreen().bounds.size.width-, )) QQNumber.placeholder = "请输入QQ号" QQNumber.layer.borderWidth = QQNumber.layer.borderColor = UIColor.lightGrayColor().CGColor QQNumber.layer.cornerRadius = QQNumber.keyboardType = UIKeyboardType.NumberPad self.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(, , UIScreen.mainScreen().bounds.size.width-, )) PassNumber.placeholder = "请输入密码" PassNumber.layer.borderWidth = PassNumber.layer.borderColor = UIColor.lightGrayColor().CGColor PassNumber.layer.cornerRadius = self.view.addSubview(PassNumber) self.PassNumber = PassNumber /// 密码找回 var button = UIButton(frame: CGRectMake(, , , )) 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() } }
