键盘 - 键盘样式风格有关设置

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;

UIKeyboardTypeDefault：

UIKeyboardTypeASCIICapable：

UIKeyboardTypeNumbersAndPunctuation：

UIKeyboardTypeURL：

UIKeyboardTypeNumberPad：

UIKeyboardTypePhonePad：

UIKeyboardTypeNamePhonePad：

UIKeyboardTypeEmailAddress：

UIKeyboardTypeDecimalPad：

UIKeyboardTypeTwitter：

UIKeyboardTypeWebSearch:

UIKeyboardTypeAlphabet:

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,  <span style="white-space:pre">	</span>//默认：灰色按钮，标有Return
    UIReturnKeyGo,  <span style="white-space:pre">		</span>//标有Go的蓝色按钮
    UIReturnKeyGoogle,  <span style="white-space:pre">	</span>//标有Google的蓝色按钮，用于搜索
    UIReturnKeyJoin, <span style="white-space:pre">		</span>//标有Join的蓝色按钮
    UIReturnKeyNext, <span style="white-space:pre">		</span>//标有Next的蓝色按钮
    UIReturnKeyRoute,  <span style="white-space:pre">		</span>//标有Route的蓝色按钮
    UIReturnKeySearch, <span style="white-space:pre">		</span>//标有Search的蓝色按钮
    UIReturnKeySend,  <span style="white-space:pre">		</span>//标有Send的蓝色按钮
    UIReturnKeyYahoo,  <span style="white-space:pre">		</span>//标有Yahoo!的蓝色按钮，用于搜索
    UIReturnKeyDone,  <span style="white-space:pre">		</span>//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, <span style="white-space:pre">		</span>//不自动大写   
    UITextAutocapitalizationTypeWords, <span style="white-space:pre">		</span>//单词首字母大写   
    UITextAutocapitalizationTypeSentences, <span style="white-space:pre">	</span>//句子首字母大写   
    UITextAutocapitalizationTypeAllCharacters, <span style="white-space:pre">	</span>//所有字母大写   
} UITextAutocapitalizationType;  

用法用例：

textField.autocapitalizationType = UITextAutocapitalizationTypeWords;

五、自动更正

typedef enum 
{  
    UITextAutocorrectionTypeDefault,<span style="white-space:pre">	</span>//默认   
    UITextAutocorrectionTypeNo,<span style="white-space:pre">		</span>//不自动更正   
    UITextAutocorrectionTypeYes,<span style="white-space:pre">	</span>//自动更正   
} UITextAutocorrectionType;  

用法用例：

textField.autocorrectionType = UITextAutocorrectionTypeYes;

六、安全文本输入（密码输入）

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。

UITextField和UITextView隐藏键盘

    self._textField.returnKeyType=UIReturnKeyDone;
    self._textField.delegate=self;
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

    self._textView.delegate=self;
    self._textView.returnKeyType=UIReturnKeyDone;
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text 
{
    if ([text isEqualToString:@"\n"]) 
    {
        [textView resignFirstResponder];
        return NO;
    }
    return YES;
}
