软键盘的属性设置

textField.clearButtonMode = UITextFieldViewModeWhileEditing;

Java代码 

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;

Java代码 

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).  
10.   
11.     UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable, // Deprecated  
12.   
13. } UIKeyboardType;  

 

键盘的呈现风格:

textField..keyboardAppearance = UIKeyboardAppearanceAlert;

Java代码 

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;

 

Java代码 

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;

Java代码 

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

 

 

确认键的类型

textField.returnKeyType = UIReturnKeyDone;

 

Java代码 

1. typedef enum {  
2.     UIReturnKeyDefault,  
3.     UIReturnKeyGo,  
4.     UIReturnKeyGoogle,  
5.     UIReturnKeyJoin,  
6.     UIReturnKeyNext,  
7.     UIReturnKeyRoute,  
8.     UIReturnKeySearch,  
9.     UIReturnKeySend,  
10.     UIReturnKeyYahoo,  
11.     UIReturnKeyDone,  
12.     UIReturnKeyEmergencyCall,  
13. } UIReturnKeyType;  

 

 

最后一个技巧,也是网上收集,键盘透明以及增加一个按键的应用:

 [[NSNotificationCenter defaultCenter] addObserver:self

Java代码 

1.                                              selector:@selector(keyboardWillShow:)   
2.                                                  name:UIKeyboardWillShowNotification   
3.                                                object:nil];  
4.   
5.   
6.   
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];  
16.   
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. }
