当文本输入时, 文本框有几中选择用于辅助输入:

textField.clearButtonMode=UITextFieldViewModeWhileEditing;

Java代码
  1. typedefenum{
  2. UITextFieldViewModeNever,//clearbutton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. typedefenum{
  2. UIKeyboardTypeDefault,//Defaulttypeforthecurrentinputmethod.
  3. UIKeyboardTypeASCIICapable,//DisplaysakeyboardwhichcanenterASCIIcharacters,non-ASCIIkeyboardsremainactive
  4. UIKeyboardTypeNumbersAndPunctuation,//Numbersandassortedpunctuation.
  5. UIKeyboardTypeURL,//AtypeoptimizedforURLentry(shows./.comprominently).
  6. UIKeyboardTypeNumberPad,//Anumberpad(0-9).SuitableforPINentry.
  7. UIKeyboardTypePhonePad,//Aphonepad(1-9,*,0,#,withlettersunderthenumbers).
  8. UIKeyboardTypeNamePhonePad,//Atypeoptimizedforenteringaperson'snameorphonenumber.
  9. UIKeyboardTypeEmailAddress,//Atypeoptimizedformultipleemailaddressentry(showsspace@.prominently).
  11. UIKeyboardTypeAlphabet=UIKeyboardTypeASCIICapable,//Deprecated
  13. }UIKeyboardType;

键盘的呈现风格:

textField..keyboardAppearance=UIKeyboardAppearanceAlert;

Java代码
  1. typedefenum{
  2. UIKeyboardAppearanceDefault,//Defaultapperanceforthecurrentinputmethod.
  3. UIKeyboardAppearanceAlert,//Appearancesuitableforusein"alert"scenarios.
  4. }UIKeyboardAppearance;

键盘对输入字母的控制:

textField.autocapitalizationType=UITextAutocapitalizationTypeAllCharacters;

Java代码
  1. typedefenum{
  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. typedefenum{
  2. UITextAutocorrectionTypeDefault,
  3. UITextAutocorrectionTypeNo,
  4. UITextAutocorrectionTypeYes,
  5. }UITextAutocorrectionType;

确认键的类型

textField.returnKeyType=UIReturnKeyDone;

Java代码
  1. typedefenum{
  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];
  7. --------------------
  8. -(void)keyboardWillShow:(NSNotification*)note{
  9. //createcustombutton
  10. UIButton*doneButton=[UIButtonbuttonWithType:UIButtonTypeCustom];
  11. doneButton.frame=CGRectMake(0,163,106,53);
  12. doneButton.adjustsImageWhenHighlighted=NO;
  13. [doneButtonsetImage:[UIImageimageNamed:@"DoneUp.png"]forState:UIControlStateNormal];
  14. [doneButtonsetImage:[UIImageimageNamed:@"DoneDown.png"]forState:UIControlStateHighlighted];
  15. [doneButtonaddTarget:selfaction:@selector(doneButton:)forControlEvents:UIControlEventTouchUpInside];
  17. //locatekeyboardview
  18. UIWindow*tempWindow=[[[UIApplicationsharedApplication]windows]objectAtIndex:1];
  19. UIView*keyboard;
  20. for(inti=0;i<[tempWindow.subviewscount];i++){
  21. keyboard=[tempWindow.subviewsobjectAtIndex:i];
  22. //keyboardviewfound;addthecustombuttontoit
  23. if([[keyboarddescription]hasPrefix:@"<UIKeyboard"]==YES)
  24. [keyboardaddSubview:doneButton];
  25. }
  26. }
