// 创建一个textField    UITextField *userNameTextField = [[UITextField alloc]initWithFrame:KFrame(0, 80, 200, 30)];    // 添加提示文字    userNameTextField.placeholder = @"请输入登录密码";        // 每输入一个字符就变成点,用密码输入    userNameTextField.secureTextEntry = YES;    // 设置return关键字    userNameTextField.returnKeyType = UIReturnKeyGo;    // 设置边框样式    userNameTextField.borderStyle = UITextBorderStyleRoundedRect;    // 设置对齐方式    userNameTextField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;    // 设置键盘类型    userNameTextField.keyboardType = UIKeyboardAppearanceDefault;    // 设置代理回收键盘    userNameTextField.delegate = self;    NSLog(@"userNameTextField = %@",userNameTextField);// 输出地址        // 设置键盘不弹出    //userNameTextField.inputView = [[UIView alloc] initWithFrame:CGRectZero];

代理方法: 需要在.h文件里面添加协议

//输入前调用-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField{    //textField.frame = CGRectMake(20, 20, 150, 30);    return YES;}// 按return执行-(BOOL)textFieldShouldReturn:(UITextField *)textField{    NSLog(@"textField = %@",textField);    NSLog(@"%s",__func__);    // 回收键盘    [textField resignFirstResponder];    return YES;}
