3.UITextField基础知识
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// UITextField:UIControl:UIView
// ============UIView的属性和方法=============
// 1. 创建UITextField对象
let textField = UITextField.init(frame: CGRectMake(100, 100, 200, 50))
// 2. 添加到界面上
self.view.addSubview(textField)
// 3. 设置背景颜色
textField.backgroundColor = UIColor.yellowColor()
// 4. 再创建一个UITextField对象
let textField1 = UITextField.init(frame: CGRectMake(100, 200, 200, 50))
self.view.addSubview(textField1)
textField1.backgroundColor = UIColor.yellowColor()
textField1.delegate = self
// ==========textField的专有属性和方法==========
// (1). 文字相关
// 1. text属性
// 设置文本输入框的内容
textField.text = ""
// 拿到文本输入框的内容
print(textField.text)
// 2. 文字颜色
textField.textColor = UIColor.brownColor()
// 3. 设置文字字体
textField.font = UIFont.systemFontOfSize(14)
// 4. 设置占位文字(在输入框的内容为空的时候就会显示出来)
textField.placeholder = "请输入账号"
// 5. 设置文本的对齐方式(默认:左对齐)
textField.textAlignment = .Left
// 6. 密文显示(默认是false)
textField.secureTextEntry = true
//(2) 显示相关
// 1. 设置文本框的样式
textField.borderStyle = .RoundedRect
// 2. 设置清除按钮模式
// Always -> 一直显示
// Never -> 从不显示(默认)
// WhileEditing -> 当文本框输入处于编辑状态的时候显示
// UnlessEditing -> 当文本框输入处于非编辑状态的时候显示
// 注: 当文本输入框中有光标的时候就是处于编辑状态
textField.clearButtonMode = .Always
// 3. 左视图
let leftImageView = UIImageView.init(frame: CGRectMake(0, 0, 50, 50))
leftImageView.image = UIImage.init(named: "luffy4")
// 设置做视图
textField.leftView = leftImageView
//设置做视图的显示模式(确定什么时候显示,默认是从不显示)
textField.leftViewMode = .Always
// 4. 右视图
// 当又视图显示的时候,清除按钮不能显示
/*
let rightLabel = UILabel.init(frame: CGRectMake(0, 0, 40, 40))
rightLabel.text = "你好"
textField.rightView = rightLabel
textField.rightViewMode = .Always
*/
// (3) 键盘相关
// 1. 设置键盘上返回按钮的样式
textField.returnKeyType = .Done
// 2. 键盘样式
textField.keyboardType = .Default
// 3.设置自定义的键盘
// 自定义的键盘,只有高度有效。宽度是屏幕的宽度
let myInputView = UIView.init(frame: CGRectMake(0, 0, 0, 256))
myInputView.backgroundColor = UIColor.redColor()
// textField.inputView = myInputView
// 4. 设置子键盘
let accessoryView = UIView.init(frame: CGRectMake(0, 0, 0, 50))
accessoryView.backgroundColor = UIColor.greenColor()
textField.inputAccessoryView = accessoryView
// (4) 设置代理
// textField -> 委托
// self -> 代理
textField.delegate = self
}
}
extension ViewController:UITextFieldDelegate {
// 6. 当按键盘上的返回按钮的时候,会自动调用
func textFieldShouldReturn(textField: UITextField) -> Bool {
print("返回按钮被点击")
// 收起键盘
// 1. 放弃第一响应者
textField.resignFirstResponder()
// 2. 直接让指定的textField结束编辑
textField.endEditing(true)
// 3. 让self.view上的所有的子视图都结束编辑
self.view.endEditing(true)
return true
}
// 5. 当点击textField弹出来的键盘上的按键的时候会自动调用这个方法
// 参数1: 委托
// 参数2: 当前输入的的字符所在的位置
// 参数3: 当前输入的字符串(在键盘上按的键的值)
// 返回值: 是否可以改变textField的text属性(); false -> 按键盘上的按键无效
func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {
print(range)
print(string)
if string == "0" {
print("进入秘密页")
}
return true
}
// 4. 当文本输入框已经结束编辑的时候会自动调用这个方法
func textFieldDidEndEditing(textField: UITextField) {
print("已经结束编辑")
}
// 2. 当文本输入框已经开始编辑的时候会自动调用这个方法
func textFieldDidBeginEditing(textField: UITextField) {
print("已经开始编辑")
}
// 3.当文本输入框将要结束编辑的时候会自动调用这个方法
// 返回: 设置当前的textField是否可以结束编辑()默认是true
func textFieldShouldEndEditing(textField: UITextField) -> Bool {
print("将要结束编辑")
// 要求文本输入框的文字长度要大于等于8的时候才能结束编辑
if textField.text?.characters.count >= 8 {
return true
}
return false
}
// 1. 在textField将要开始编辑的时候会自动调用
// 参数:当前这个协议对应的的委托
// 返回值:设置当前的textField是否可以进行编辑(默认是true)
func textFieldShouldBeginEditing(textField: UITextField) -> Bool {
print("将要开始编辑")
return true // false -> 让textField不能进行编辑
}
}
