IOS键盘UIKeyboard相关知识点
一、键盘风格
UIKit框架支持8种风格键盘。
[java] view plaincopy
- 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;
[java] view plaincopy
- 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;
二、键盘外观
[java] view plaincopy
- typedef enum {
- UIKeyboardAppearanceDefault, // 默认外观:浅灰色
- UIKeyboardAppearanceAlert, //深灰/石墨色
- } UIKeyboardAppearance;
[java] view plaincopy
- 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, //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
[java] 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;
[java] 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
[java] view plaincopy
- typedef enum {
- UITextAutocorrectionTypeDefault,//默认
- UITextAutocorrectionTypeNo,//不自动更正
- UITextAutocorrectionTypeYes,//自动更正
- } UITextAutocorrectionType;
[java] 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。
七、键盘遮住视图
这个问题又来已久,我专门写了篇文章来解决此问题,请笑纳:
