var imageview = UIImageView(frame: self.view.bounds)

let image = UIImage(named: "1.png")

imageview.image = image

self.view.addSubview(imageview)

// 定义用户名输入框

var text = UITextField(frame: CGRectMake(30,100,UIScreen.mainScreen().bounds.size.width-60,30))

text.delegate = self

text.keyboardType = UIKeyboardType.Default

text.layer.borderWidth = 0.5

text.layer.borderColor = UIColor.lightGrayColor().CGColor

text.placeholder = "请输入用户名"

text.clearButtonMode = UITextFieldViewMode.Always

self.view.addSubview(text)

text.returnKeyType = UIReturnKeyType.Done

self.text = text

let lab = UILabel(frame: CGRectMake(0,70,text.bounds.size.height))

lab.text = "用户名："

text.leftView = lab

// lab.font = UIFont.systemFontOfSize(17.0)

text.leftViewMode = UITextFieldViewMode.Always

var pwdtext = UITextField(frame: CGRectMake(30,150,30))

pwdtext.delegate = self

pwdtext.keyboardType = UIKeyboardType.NumberPad

pwdtext.layer.borderWidth = 0.5

pwdtext.layer.borderColor = UIColor.lightGrayColor().CGColor

pwdtext.placeholder = "请输入文字"

pwdtext.clearButtonMode = UITextFieldViewMode.WhileEditing

self.view.addSubview(pwdtext)

pwdtext.returnKeyType = UIReturnKeyType.Done

self.pwdtext = pwdtext

let pwd = UILabel(frame: CGRectMake(0,text.bounds.size.height))

pwd.text = "验证码："

pwdtext.leftView = pwd

pwd.font = UIFont.systemFontOfSize(17.0)

pwdtext.leftViewMode = UITextFieldViewMode.Always

// Do any additional seuitup after loading the view,typically from a nib.

}

// 第一种是遵循代理，是在代理方法中实现键盘的隐藏

override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()

// Dispose of any resources that can be recreated.

}

// 第一种方法。用代理实现键盘的隐藏

func textFieldShouldReturn(textField: UITextField) -> Bool {

if (textField == self.text) {

textField.resignFirstResponder()

// self.view.becomeFirstResponder()

}

return true;

}

// 第二种方法实现键盘的隐藏

override func touchesBegan(touches: NSSet,withEvent event: UIEvent) {

self.text.resignFirstResponder()

self.pwdtext.resignFirstResponder()

}

}
