[super viewDidLoad];

//新建一个UITextField
myTextField = [[UITextField alloc]initWithFrame:CGRectMake(0, 100, 300, 50)];

//设置边框
[myTextField setBorderStyle:UITextBorderStyleRoundedRect];

//设置键盘的样式
myTextField.keyboardType =  UIKeyboardTypeNamePhonePad;

[self.view addSubview:myTextField];

//让虚拟键盘在完成输入后收回（点空白处就收回了）

}
