键盘样式风格设置及隐藏

一、键盘风格   

UIKit框架支持8种风格键盘。

  1. typedef  enum  {  
  2.     UIKeyboardTypeDefault,                 // 默认键盘:支持所有字符   
  3.     UIKeyboardTypeASCIICapable,            // 支持ASCII的默认键盘   
  4.     UIKeyboardTypeNumbersAndPunctuation,   // 标准电话键盘,支持+*#等符号   
  5.     UIKeyboardTypeURL,                     // URL键盘,有.com按钮;只支持URL字符   
  6.     UIKeyboardTypeNumberPad,               //数字键盘   
  7.     UIKeyboardTypePhonePad,                // 电话键盘   
  8.     UIKeyboardTypeNamePhonePad,            // 电话键盘,也支持输入人名字   
  9.     UIKeyboardTypeEmailAddress,            // 用于输入电子邮件地址的键盘   
  10. } UIKeyboardType;  

用法用例:

textView.keyboardtype = UIKeyboardTypeNumberPad;

二、键盘外观

  1. typedef  enum  {  
  2.     UIKeyboardAppearanceDefault,     // 默认外观:浅灰色   
  3.     UIKeyboardAppearanceAlert,       //深灰/石墨色   
  4. } UIKeyboardAppearance;  

用法用例:

textView.keyboardAppearance=UIKeyboardAppearanceDefault;

三、回车键

  1. typedef  enum  {  
  2.     UIReturnKeyDefault,  //默认:灰色按钮,标有Return
  3.     UIReturnKeyGo,  //标有Go的蓝色按钮
  4.     UIReturnKeyGoogle,  //标有Google的蓝色按钮,用于搜索
  5.     UIReturnKeyJoin,  //标有Join的蓝色按钮
  6.     UIReturnKeyNext,  //标有Next的蓝色按钮
  7.     UIReturnKeyRoute,  //标有Route的蓝色按钮
  8.     UIReturnKeySearch,  //标有Search的蓝色按钮
  9.     UIReturnKeySend,  //标有Send的蓝色按钮
  10.     UIReturnKeyYahoo,  //标有Yahoo!的蓝色按钮,用于搜索
  11.     UIReturnKeyDone,  //标有Done的蓝色按钮
  12.     UIReturnKeyEmergencyCall,  //紧急呼叫按钮
  13. } UIReturnKeyType;  

用法用例:

textView.returnKeyType=UIReturnKeyGo;

四、自动大写

  1. typedef  enum  {  
  2.     UITextAutocapitalizationTypeNone,  //不自动大写   
  3.     UITextAutocapitalizationTypeWords,  //单词首字母大写   
  4.     UITextAutocapitalizationTypeSentences,  //句子首字母大写   
  5.     UITextAutocapitalizationTypeAllCharacters,  //所有字母大写   
  6. } UITextAutocapitalizationType;  

用法用例:

textField.autocapitalizationType  =  UITextAutocapitalizationTypeWords ;

五、自动更正

  1. typedef  enum  {  
  2.     UITextAutocorrectionTypeDefault, //默认   
  3.     UITextAutocorrectionTypeNo, //不自动更正   
  4.     UITextAutocorrectionTypeYes, //自动更正   
  5. } 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;

}
