物料组件-文本字段-IOS [英] Material Components - Text Field - IOS

问题描述

我是快速编程的新手，我需要使用浮动占位符输入来设计登录页面.我已经使用POD安装了MDCTextInput.

I'm newbie to swift programming, i need to design the login page with floating placeholder input. I have installed the MDCTextInput using POD.

添加了导入

import MaterialComponents.MaterialTextFields

并在以下代码的viewDidLoad()中添加了

and in viewDidLoad() below code added,

companyID.placeholder = "Company ID"
companyID.placeholderLabel.highlightedTextColor = UIColor.white
companyID.placeholderLabel.textColor = UIColor.white
companyID.underline?.color = UIColor.white
companyID.delegate = self

我遵循了IOS中材料组件"中给出的步骤

i have followed the steps given in Material components in IOS

我不清楚这条线，

To achieve the animations and presentations defined by the guidelines (floating placeholders, character counts), a controller that conforms to protocol MDCTextInputController must be initialized to manage the text field.

我没有获得浮动占位符动画，如何在swift4中做到这一点?请任何人给我一个主意.

I am not getting floating placeholder animation, how to do this in swift4 ? please anybody provide me an idea .
