一、键盘风格   
UIKit框架支持8种风格键盘。
class="dp-j">
- typedef  enum  {  
-     UIKeyboardTypeDefault,                 
-     UIKeyboardTypeASCIICapable,            
-     UIKeyboardTypeNumbersAndPunctuation,   
-     UIKeyboardTypeURL,                     
-     UIKeyboardTypeNumberPad,               
-     UIKeyboardTypePhonePad,                
-     UIKeyboardTypeNamePhonePad,            
-     UIKeyboardTypeEmailAddress,            
- } UIKeyboardType;  
用法用例:
textView.keyboardtype = UIKeyboardTypeNumberPad;
二、键盘外观
- typedef  enum  {  
-     UIKeyboardAppearanceDefault,     
-     UIKeyboardAppearanceAlert,       
- } UIKeyboardAppearance;  
用法用例:
textView.keyboardAppearance=UIKeyboardAppearanceDefault;
三、回车键
monospace; margin: 0px 0px 1px; padding: 2px 0px; border: 1px solid #d1d7dc; text-align: left; color: #2b91af; text-transform: none; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; font-size-adjust: none; font-stretch: normal; background-color: #ffffff; -webkit-text-stroke-width: 0px;">
- 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,  
-     UITextAutocapitalizationTypeWords,  
-     UITextAutocapitalizationTypeSentences,  
-     UITextAutocapitalizationTypeAllCharacters,  
- } UITextAutocapitalizationType;  
用法用例:
textField.autocapitalizationType  =  UITextAutocapitalizationTypeWords ; 
五、自动更正
- typedef  enum  {  
-     UITextAutocorrectionTypeDefault, 
-     UITextAutocorrectionTypeNo, 
-     UITextAutocorrectionTypeYes, 
- } 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;
}
 
那么如何控制某种类型的特定的一个按钮的显示或者隐藏,可以做到吗?
