UITextField 键盘

typedefenum{      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;

typedefenum{      UIKeyboardAppearanceDefault,// 默认外观：浅灰色UIKeyboardAppearanceAlert,//深灰/石墨色

} UIKeyboardAppearance;

用法用例：

textView.keyboardAppearance=UIKeyboardAppearanceDefault;

typedefenum{      UIReturnKeyDefault,//默认：灰色按钮，标有ReturnUIReturnKeyGo,//标有Go的蓝色按钮UIReturnKeyGoogle,//标有Google的蓝色按钮，用于搜索UIReturnKeyJoin,//标有Join的蓝色按钮UIReturnKeyNext,//标有Next的蓝色按钮UIReturnKeyRoute,//标有Route的蓝色按钮UIReturnKeySearch,//标有Search的蓝色按钮UIReturnKeySend,//标有Send的蓝色按钮UIReturnKeyYahoo,//标有Yahoo!的蓝色按钮，用于搜索UIReturnKeyDone,//标有Done的蓝色按钮UIReturnKeyEmergencyCall,//紧急呼叫按钮} UIReturnKeyType;

用法用例：

textView.returnKeyType=UIReturnKeyGo;

typedefenum{      UITextAutocapitalizationTypeNone,//不自动大写UITextAutocapitalizationTypeWords,//单词首字母大写UITextAutocapitalizationTypeSentences,//句子首字母大写UITextAutocapitalizationTypeAllCharacters,//所有字母大写} UITextAutocapitalizationType;

用法用例：

textField.autocapitalizationType=UITextAutocapitalizationTypeWords;

typedefenum{      UITextAutocorrectionTypeDefault,//默认UITextAutocorrectionTypeNo,//不自动更正UITextAutocorrectionTypeYes,//自动更正} UITextAutocorrectionType;

用法用例：

textField.autocorrectionType=UITextAutocorrectionTypeYes;

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。

解决虚拟键盘挡住UITextField的方法：

-(BOOL)textFieldShouldReturn:(UITextField*)textField

{

NSTimeIntervalanimationDuration =0.30f;

[UIViewbeginAnimations:@"ResizeForKeyboard"context:nil];

[UIViewsetAnimationDuration:animationDuration];

CGRectrect =CGRectMake(0.0f,64,self.view.frame.size.width,self.view.frame.size.height);

self.view.frame= rect;

[UIViewcommitAnimations];

[textFieldresignFirstResponder];

returnYES;

}

- (void)textFieldDidBeginEditing:(UITextField*)textField

{

CGRectframe = textField.frame;

intoffset = frame.origin.y+32- (self.view.frame.size.height-260.0);//键盘高度216

NSTimeIntervalanimationDuration =0.30f;

[UIViewbeginAnimations:@"ResizeForKeyBoard"context:nil];

[UIViewsetAnimationDuration:animationDuration];

floatwidth =self.view.frame.size.width;

floatheight =self.view.frame.size.height;

if(offset >0)

{

CGRectrect =CGRectMake(0.0f, -offset,width,height);

self.view.frame= rect;

}

[UIViewcommitAnimations];

}

-(void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event

{

NSTimeIntervalanimationDuration =0.30f;

[UIViewbeginAnimations:@"ResizeForKeyboard"context:nil];

[UIViewsetAnimationDuration:animationDuration];

CGRectrect =CGRectMake(0.0f,64,self.view.frame.size.width,self.view.frame.size.height);

self.view.frame= rect;

[UIViewcommitAnimations];

[_titleTextresignFirstResponder];

[_contentTextresignFirstResponder];

}
