键盘设置

一、键盘风格

UIKit框架支持13种风格键盘。

二、键盘外观

[cpp] view plaincopy
typedef enum {
UIKeyboardAppearanceDefault, // 默认外观：浅灰色
UIKeyboardAppearanceAlert, //深灰/石墨色
} UIKeyboardAppearance;
textView.keyboardAppearance=UIKeyboardAppearanceDefault;

三、回车键

[cpp] view plaincopy
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

[cpp] view plaincopy
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;
textField.autocapitalizationType = UITextAutocapitalizationTypeWords;

五、自动更正

[cpp] view plaincopy
typedef enum {
UITextAutocorrectionTypeDefault,//默认
UITextAutocorrectionTypeNo,//不自动更正
UITextAutocorrectionTypeYes,//自动更正
} UITextAutocorrectionType;
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。
