鍵盤樣式風格設置及隱藏

1、鍵盤風格   api

UIKit框架支持8種風格鍵盤。緩存

  1. typedef  enum  {  
  2.     UIKeyboardTypeDefault,                 // 默認鍵盤:支持全部字符   
  3.     UIKeyboardTypeASCIICapable,            // 支持ASCII的默認鍵盤   
  4.     UIKeyboardTypeNumbersAndPunctuation,   // 標準電話鍵盤,支持+*#等符號   
  5.     UIKeyboardTypeURL,                     // URL鍵盤,有.com按鈕;只支持URL字符   
  6.     UIKeyboardTypeNumberPad,               //數字鍵盤   
  7.     UIKeyboardTypePhonePad,                // 電話鍵盤   
  8.     UIKeyboardTypeNamePhonePad,            // 電話鍵盤,也支持輸入人名字   
  9.     UIKeyboardTypeEmailAddress,            // 用於輸入電子郵件地址的鍵盤   
  10. } UIKeyboardType;  

用法用例:安全

textView.keyboardtype = UIKeyboardTypeNumberPad;app

2、鍵盤外觀框架

  1. typedef  enum  {  
  2.     UIKeyboardAppearanceDefault,     // 默認外觀:淺灰色   
  3.     UIKeyboardAppearanceAlert,       //深灰/石墨色   
  4. } UIKeyboardAppearance;  

用法用例:spa

textView.keyboardAppearance=UIKeyboardAppearanceDefault;接口

3、回車鍵it

  1. typedef  enum  {  
  2.     UIReturnKeyDefault,  //默認:灰色按鈕,標有Return
  3.     UIReturnKeyGo,  //標有Go的藍色按鈕
  4.     UIReturnKeyGoogle,  //標有Google的藍色按鈕,用於搜索
  5.     UIReturnKeyJoin,  //標有Join的藍色按鈕
  6.     UIReturnKeyNext,  //標有Next的藍色按鈕
  7.     UIReturnKeyRoute,  //標有Route的藍色按鈕
  8.     UIReturnKeySearch,  //標有Search的藍色按鈕
  9.     UIReturnKeySend,  //標有Send的藍色按鈕
  10.     UIReturnKeyYahoo,  //標有Yahoo!的藍色按鈕,用於搜索
  11.     UIReturnKeyDone,  //標有Done的藍色按鈕
  12.     UIReturnKeyEmergencyCall,  //緊急呼叫按鈕
  13. } UIReturnKeyType;  

用法用例:io

textView.returnKeyType=UIReturnKeyGo;class

4、自動大寫

  1. typedef  enum  {  
  2.     UITextAutocapitalizationTypeNone,  //不自動大寫   
  3.     UITextAutocapitalizationTypeWords,  //單詞首字母大寫   
  4.     UITextAutocapitalizationTypeSentences,  //句子首字母大寫   
  5.     UITextAutocapitalizationTypeAllCharacters,  //全部字母大寫   
  6. } UITextAutocapitalizationType;  

用法用例:

textField.autocapitalizationType  =  UITextAutocapitalizationTypeWords ;

5、自動更正

  1. typedef  enum  {  
  2.     UITextAutocorrectionTypeDefault, //默認   
  3.     UITextAutocorrectionTypeNo, //不自動更正   
  4.     UITextAutocorrectionTypeYes, //自動更正   
  5. } UITextAutocorrectionType;  

用法用例:

textField . autocorrectionType  =  UITextAutocorrectionTypeYes ;

6、安全文本輸入

textView.secureTextEntry=YES;

開啓安全輸入主要是用於密碼或一些私人數據的輸入,此時會禁用自動更正和自此緩存。

 

那麼如何設置鍵盤類型呢?

接下來,請看:

在TextviewDelegate的這個方法設置:

// 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;

}

 

關於鍵盤的隱藏

首先在ViewController接口上添加<UITextFieldDelegate>

而後實現以下:

UITextField *text = [[UITextFieldalloc]initWithFrame:CGRectMake(100, 152, 130, 20)];

text.returnKeyType = UIReturnKeyDefault;//返回鍵類型

text.placeholder = @"請輸入姓名";

text.borderStyle = UITextBorderStyleRoundedRect;

text.keyboardAppearance = UIKeyboardTypeNamePhonePad;//鍵盤類型

text.returnKeyType = UIReturnKeyDone;

text.delegate = self;

[self.viewaddSubview:text];

 

實現如下方法:

-(void)viewTapped:(UITapGestureRecognizer*)tapGr{

    [text resignFirstResponder];

}

-(BOOL) textFieldShouldReturn:(UITextField *)textField {

    [textField resignFirstResponder];

    returnYES;

}
