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;
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, //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, //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;
用法用例:
textField.autocapitalizationType = UITextAutocapitalizationTypeWords ;
五、自动更正
- typedef enum {
- UITextAutocorrectionTypeDefault, //默认
- UITextAutocorrectionTypeNo, //不自动更正
- UITextAutocorrectionTypeYes, //自动更正
- } 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?
