iphone 软键盘设置参数说明

当文本输入时, 文本框有几中选择用于辅助输入:

textField.clearButtonMode = UITextFieldViewModeWhileEditing;

1. typedef enum {
2.     UITextFieldViewModeNever, //clear button 永远不出现
3.     UITextFieldViewModeWhileEditing, //编辑的时候出现
4.     UITextFieldViewModeUnlessEditing, //未编辑的时候出现
5.     UITextFieldViewModeAlways //永远都出现
6. } UITextFieldViewMode;

 

 

弹出的键盘类型也可以辅助快速输入:

textField.keyboardType = UIKeyboardTypeAlphabet;

1. typedef enum {
2.     UIKeyboardTypeDefault,                // Default type for the current input method.
3.     UIKeyboardTypeASCIICapable,           // Displays a keyboard which can enter ASCII characters, non-ASCII keyboards remain active
4.     UIKeyboardTypeNumbersAndPunctuation,  // Numbers and assorted punctuation.
5.     UIKeyboardTypeURL,                    // A type optimized for URL entry (shows . / .com prominently).
6.     UIKeyboardTypeNumberPad,              // A number pad (0-9). Suitable for PIN entry.
7.     UIKeyboardTypePhonePad,               // A phone pad (1-9, *, 0, #, with letters under the numbers).
8.     UIKeyboardTypeNamePhonePad,           // A type optimized for entering a person’s name or phone number.
9.     UIKeyboardTypeEmailAddress,           // A type optimized for multiple email address entry (shows space @ . prominently).
11.     UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable, // Deprecated
13. } UIKeyboardType;

 

键盘的呈现风格:

textField..keyboardAppearance = UIKeyboardAppearanceAlert;

1. typedef enum {
2.     UIKeyboardAppearanceDefault,          // Default apperance for the current input method.
3.     UIKeyboardAppearanceAlert,            // Appearance suitable for use in ”alert” scenarios.
4. } UIKeyboardAppearance;

 

键盘对输入字母的控制:

textField.autocapitalizationType = UITextAutocapitalizationTypeAllCharacters;

1. typedef enum {
2.     UITextAutocapitalizationTypeNone, //什么也不做
3.     UITextAutocapitalizationTypeWords, //单词首字母大写
4.     UITextAutocapitalizationTypeSentences, //句子首字母大些
5.     UITextAutocapitalizationTypeAllCharacters, //所有字母大些
6. } UITextAutocapitalizationType;

 

键盘对输入字母自动纠正

textField.autocorrectionType = UITextAutocorrectionTypeYes;

1. typedef enum {
2.     UITextAutocorrectionTypeDefault,
3.     UITextAutocorrectionTypeNo,
4.     UITextAutocorrectionTypeYes,
5. } UITextAutocorrectionType;

 

确认键的类型

textField.returnKeyType = UIReturnKeyDone;

1. typedef enum {
2.     UIReturnKeyDefault,
3.     UIReturnKeyGo,
4.     UIReturnKeyGoogle,
5.     UIReturnKeyJoin,
6.     UIReturnKeyNext,

10.     UIReturnKeyYahoo,
11.     UIReturnKeyDone,
12.     UIReturnKeyEmergencyCall,
13. } UIReturnKeyType;

 

 

键盘透明以及增加一个按键的应用:

[[NSNotificationCenter defaultCenter] addObserver:self

1.                                              selector:@selector(keyboardWillShow:)
2.                                                  name:UIKeyboardWillShowNotification
3.                                                object:nil];
7. ——————–
8. - (void)keyboardWillShow:(NSNotification *)note {
9.     // create custom button
10.     UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
11.     doneButton.frame = CGRectMake(0, 163, 106, 53);
12.     doneButton.adjustsImageWhenHighlighted = NO;
13.     [doneButton setImage:[UIImage imageNamed:@"DoneUp.png"] forState:UIControlStateNormal];
14.     [doneButton setImage:[UIImage imageNamed:@"DoneDown.png"] forState:UIControlStateHighlighted];
15.     [doneButton addTarget:self action:@selector(doneButton:) forControlEvents:UIControlEventTouchUpInside];
17.     // locate keyboard view
18.     UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
19.     UIView* keyboard;
20.     for(int i=0; i<[tempWindow.subviews count]; i++) {
21.         keyboard = [tempWindow.subviews objectAtIndex:i];
22.         // keyboard view found; add the custom button to it
23.         if([[keyboard description] hasPrefix:@”<UIKeyboard”] == YES)
24.             [keyboard addSubview:doneButton];
25.     }
26. }
