當文本輸入時, 文本框有幾中選擇用于輔助輸入:

?

textField.clearButtonMode?=?UITextFieldViewModeWhileEditing;

?

Java代碼?

typedef?enum?{??

????UITextFieldViewModeNever,?//clear?button?永遠不出現??

????UITextFieldViewModeWhileEditing,?//編輯的時候出現??

????UITextFieldViewModeUnlessEditing,?//未編輯的時候出現??

????UITextFieldViewModeAlways?//永遠都出現??

}?UITextFieldViewMode;??

?

?

彈出的鍵盤類型也可以輔助快速輸入:

?

textField.keyboardType?=?UIKeyboardTypeAlphabet;

?

Java代碼?

typedef?enum?{??

????UIKeyboardTypeDefault,????????????????//?Default?type?for?the?current?input?method.??

????UIKeyboardTypeASCIICapable,???????????//?Displays?a?keyboard?which?can?enter?ASCII?characters,?non-ASCII?keyboards?remain?active??

????UIKeyboardTypeNumbersAndPunctuation,??//?Numbers?and?assorted?punctuation.??

????UIKeyboardTypeURL,????????????????????//?A?type?optimized?for?URL?entry?(shows?.?/?.com?prominently).??

????UIKeyboardTypeNumberPad,??????????????//?A?number?pad?(0-9).?Suitable?for?PIN?entry.??

????UIKeyboardTypePhonePad,???????????????//?A?phone?pad?(1-9,?*,?0,?#,?with?letters?under?the?numbers).??

????UIKeyboardTypeNamePhonePad,???????????//?A?type?optimized?for?entering?a?person's?name?or?phone?number.??

????UIKeyboardTypeEmailAddress,???????????//?A?type?optimized?for?multiple?email?address?entry?(shows?space?@?.?prominently).??

??

????UIKeyboardTypeAlphabet?=?UIKeyboardTypeASCIICapable,?//?Deprecated??

??

}?UIKeyboardType;??

?

鍵盤的呈現風格:

textField..keyboardAppearance?=?UIKeyboardAppearanceAlert;

?

Java代碼?

typedef?enum?{??

????UIKeyboardAppearanceDefault,??????????//?Default?apperance?for?the?current?input?method.??

????UIKeyboardAppearanceAlert,????????????//?Appearance?suitable?for?use?in?"alert"?scenarios.??

}?UIKeyboardAppearance;??

?

鍵盤對輸入字母的控制:

?

textField.autocapitalizationType?=?UITextAutocapitalizationTypeAllCharacters;

?

Java代碼?

typedef?enum?{??

????UITextAutocapitalizationTypeNone,?//什么也不做??

????UITextAutocapitalizationTypeWords,?//單詞首字母大寫??

????UITextAutocapitalizationTypeSentences,?//句子首字母大些??

????UITextAutocapitalizationTypeAllCharacters,?//所有字母大些??

}?UITextAutocapitalizationType;??

?

鍵盤對輸入字母自動糾正

textField.autocorrectionType?=?UITextAutocorrectionTypeYes;

?

Java代碼?

typedef?enum?{??

????UITextAutocorrectionTypeDefault,??

????UITextAutocorrectionTypeNo,??

????UITextAutocorrectionTypeYes,??

}?UITextAutocorrectionType;??

?

?

確認鍵的類型

textField.returnKeyType?=?UIReturnKeyDone;

?

Java代碼?

typedef?enum?{??

????UIReturnKeyDefault,??

????UIReturnKeyGo,??

????UIReturnKeyGoogle,??

????UIReturnKeyJoin,??

????UIReturnKeyNext,??

????UIReturnKeyRoute,??

????UIReturnKeySearch,??

????UIReturnKeySend,??

????UIReturnKeyYahoo,??

????UIReturnKeyDone,??

????UIReturnKeyEmergencyCall,??

}?UIReturnKeyType;??

?

?

最后一個技巧,也是網上收集,鍵盤透明以及增加一個按鍵的應用:

?[[NSNotificationCenter defaultCenter] addObserver:self

Java代碼?

?????????????????????????????????????????????selector:@selector(keyboardWillShow:)???

?????????????????????????????????????????????????name:UIKeyboardWillShowNotification???

???????????????????????????????????????????????object:nil];??

??

??

??

--------------------??

-?(void)keyboardWillShow:(NSNotification?*)note?{????

????//?create?custom?button??

????UIButton?*doneButton?=?[UIButton?buttonWithType:UIButtonTypeCustom];??

????doneButton.frame?=?CGRectMake(0,?163,?106,?53);??

????doneButton.adjustsImageWhenHighlighted?=?NO;??

????[doneButton?setImage:[UIImage?imageNamed:@"DoneUp.png"]?forState:UIControlStateNormal];??

????[doneButton?setImage:[UIImage?imageNamed:@"DoneDown.png"]?forState:UIControlStateHighlighted];??

????[doneButton?addTarget:self?action:@selector(doneButton:)?forControlEvents:UIControlEventTouchUpInside];??

??

????//?locate?keyboard?view??

????UIWindow*?tempWindow?=?[[[UIApplication?sharedApplication]?windows]?objectAtIndex:1];??

????UIView*?keyboard;??

????for(int?i=0;?i<[tempWindow.subviews?count];?i++)?{??

????????keyboard?=?[tempWindow.subviews?objectAtIndex:i];??

????????//?keyboard?view?found;?add?the?custom?button?to?it??

????????if([[keyboard?description]?hasPrefix:@"<UIKeyboard"]?==?YES)??

????????????[keyboard?addSubview:doneButton];??

????}??

} ?
