6.UITextField和UITableView自定义下拉列表框
7.使用UIPickerView在UITextField实现滚动选择
8.使用UIDatePicker在UITextField实现日期选择
一、键盘风格
UIKit框架支持8种风格键盘。
typedef enum { UIKeyboardTypeDefault, // 默认键盘：支持所有字符 UIKeyboardTypeASCIICapable, // 支持ASCII的默认键盘 UIKeyboardTypeNumbersAndPunctuation, // 标准电话键盘，支持+*#等符号 UIKeyboardTypeURL, // URL键盘，有.com按钮；只支持URL字符 UIKeyboardTypeNumberPad, //数字键盘 UIKeyboardTypePhonePad, // 电话键盘 UIKeyboardTypeNamePhonePad, // 电话键盘，也支持输入人名字 UIKeyboardTypeEmailAddress, // 用于输入电子邮件地址的键盘 } UIKeyboardType;
用法用例：textView.keyboardtype = UIKeyboardTypeNumberPad;
二、键盘外观
typedef enum { UIKeyboardAppearanceDefault, // 默认外观：浅灰色 UIKeyboardAppearanceAlert, //深灰/石墨色 } UIKeyboardAppearance;
用法用例：textView.keyboardAppearance=UIKeyboardAppearanceDefault;
三、回车键
typedef enum { UIReturnKeyDefault, //默认：灰色按钮，标有Return UIReturnKeyGo, //标有Go的蓝色按钮 UIReturnKeyGoogle, //标有Google的蓝色按钮，用于搜索 UIReturnKeyJoin, //标有Join的蓝色按钮 UIReturnKeyNext, //标有Next的蓝色按钮 UIReturnKeyRoute, //标有Route的蓝色按钮 UIReturnKeySearch, //标有Search的蓝色按钮 UIReturnKeySend, //标有Send的蓝色按钮 UIReturnKeyYahoo, //标有Yahoo!的蓝色按钮，用于搜索 UIReturnKeyDone, //标有Done的蓝色按钮 UIReturnKeyEmergencyCall, //紧急呼叫按钮 } UIReturnKeyType;
用法用例：textView.returnKeyType=UIReturnKeyGo;
四、自动大写
typedef enum { UITextAutocapitalizationTypeNone, //不自动大写 UITextAutocapitalizationTypeWords, //单词首字母大写 UITextAutocapitalizationTypeSentences, //句子首字母大写 UITextAutocapitalizationTypeAllCharacters, //所有字母大写 } UITextAutocapitalizationType;
用法用例：textField.autocapitalizationType = UITextAutocapitalizationTypeWords;
五、自动更正
typedef enum { UITextAutocorrectionTypeDefault,//默认 UITextAutocorrectionTypeNo,//不自动更正 UITextAutocorrectionTypeYes,//自动更正 } UITextAutocorrectionType;
用法用例：textField.autocorrectionType = UITextAutocorrectionTypeYes;
六、安全文本输入
textView.secureTextEntry=YES;
开启安全输入主要是用于密码或一些私人数据的输入，此时会禁用自动更正和自此缓存。
//点击回车键的回调
UITextFieldDelegate -(BOOL)textFieldShouldReturn:(UITextField *)textField{ return YES; }
//结束触摸 - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { //isExclusiveTouch一个布尔值来指示接收机处理触摸事件。 //没有触摸_textUser进入if内操作 if (![_textUser isExclusiveTouch]) { //resignFirstResponder取消第一响应者状态的。如果对textfield使用的话，那么调用这个方法，textfield的第一响应者状态就会取消，然后键盘就消失了。 [_textUser resignFirstResponder]; } }
//或者
//结束触摸 -(void)touchesEnded:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{ [self.view endEditing:YES];//收回键盘 }
//需要处理输入框被键盘挡住的.h文件，遵守UITextFieldDelegate协议
#import <UIKit/UIKit.h> #import "MyKeyboard.h" @interface Test2ViewController : UIViewController<MykeyBoardDelegate,UITextFieldDelegate> @end
//需要处理输入框被键盘挡住的.m文件，实现UITextFieldDelegate协议方法
//实现委托 _textUser.tag=1; _textUser.delegate=self; _textPwd.tag=2; _textPwd.delegate=self;
//选中开始编辑文本框内容
-(void)textFieldDidBeginEditing:(UITextField *)textField{ _textTag=textField.tag; //根据tag判断这个键盘是否是被遮住的键盘 if (_textTag==2) { //将界面上移避免文本框被键盘挡住 CGRect frame = self.view.frame; frame.origin.y -=200; frame.size.height +=200; self.view.frame = frame; } }
//结束编辑文本框内容
-(void)textFieldDidEndEditing:(UITextField *)textField{ //根据tag判断这个键盘是否是被遮住的键盘 if (_textTag==2) { CGRect frame=self.view.frame; frame.origin.y+=200; frame.size.height-=200; self.view.frame=frame; } }
//MyKeyboard.h文件（自定义键盘）
#import <UIKit/UIKit.h> @protocol MykeyBoardDelegate<NSObject> //文本框值输入委托 -(void)myKeyBoardInput:(NSString *)inputString; //删除文本框字委托 -(void)myKeyBoardBack; //隐藏键盘委托 -(void)myKeyBoardOK; @end @interface MyKeyboard : UIView @property (nonatomic,weak) id<MykeyBoardDelegate> delegate;//声明一个委托变量 @end
