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。
那么如何设置键盘类型呢？
接下来，请看：
在TextviewDelegate的这个方法设置：
// return NO to disallow editing.
-
(BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
textView.keyboardtype = UIKeyboardTypeNumberPad;
//textField.returnKeyType =
UIReturnKeyYahoo;//the same as
search
//textField.returnKeyType =
UIReturnKeyEmergencyCall;
//EmergencyCall
//textField.returnKeyType
= UIReturnKeyGoogle;//the same as
search
textField.returnKeyType =
UIReturnKeyDefault;
}
关于键盘的隐藏
首先在ViewController接口上添加<UITextFieldDelegate>
然后实现如下：
UITextField *text ＝ [[UITextFieldalloc]initWithFrame:CGRectMake(100, 152, 130, 20)];
text.returnKeyType = UIReturnKeyDefault;//返回键类型
text.placeholder = @"请输入姓名";
text.borderStyle = UITextBorderStyleRoundedRect;
text.keyboardAppearance = UIKeyboardTypeNamePhonePad;//键盘类型
text.returnKeyType = UIReturnKeyDone;
text.delegate = self;
[self.viewaddSubview:text];
实现以下方法：
-(void)viewTapped:(UITapGestureRecognizer*)tapGr{
[text resignFirstResponder];
}
-(BOOL) textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
returnYES;
}
