键盘
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ReturnUIReturnKeyGo, <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;
}
