一、键盘风格
UIKit框架支持8种风格键盘。
- typedef enum {
- UIKeyboardTypeDefault,
- UIKeyboardTypeASCIICapable,
- UIKeyboardTypeNumbersAndPunctuation,
- UIKeyboardTypeURL,
- UIKeyboardTypeNumberPad,
- UIKeyboardTypePhonePad,
- UIKeyboardTypeNamePhonePad,
- UIKeyboardTypeEmailAddress,
- } UIKeyboardType;
用法用例:
textView.keyboardtype = UIKeyboardTypeNumberPad;
二、键盘外观
- typedef enum {
- UIKeyboardAppearanceDefault,
- UIKeyboardAppearanceAlert,
- } UIKeyboardAppearance;
用法用例:
textView.keyboardAppearance=UIKeyboardAppearanceDefault;
三、回车键
- typedef enum {
- UIReturnKeyDefault, //默认:灰色按钮,标有Return
- UIReturnKeyGo, //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;
四、自动大写
- typedef enum {
- UITextAutocapitalizationTypeNone,
- UITextAutocapitalizationTypeWords,
- UITextAutocapitalizationTypeSentences,
- UITextAutocapitalizationTypeAllCharacters,
- } UITextAutocapitalizationType;
用法用例:
textField.autocapitalizationType = UITextAutocapitalizationTypeWords;
五、自动更正
- typedef enum {
- UITextAutocorrectionTypeDefault,
- UITextAutocorrectionTypeNo,
- UITextAutocorrectionTypeYes,
- } UITextAutocorrectionType;
用法用例:
textField.autocorrectionType = UITextAutocorrectionTypeYes;
六、安全文本输入
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。

七、键盘遮住视图
默认情况下打开键盘会遮住下面的view,带来一点点困扰,不过这不是什么大问题,我们使用点小小的手段就可以解决。
首先我们要知道键盘的高度是固定不变的,不过在IOS 5.0 以后键盘的高度貌似不是216了,不过不要紧,我们调整调整就是了:
| iPhone | ipad |
竖屏(portrait) | 216 | 264 |
横屏(landScape) | 140 | 352 |
我们采取的方法就是在textField(有可能是其他控件)接收到弹出键盘事件时把self.view整体上移216px了(我们就以iPhone竖屏为例了)。
有关View的frame,origin,size之类的知识点不懂的请参看我的另一篇博文: <<有关View的几个基础知识点>>
首先我们要设置textField的代理,我们就设为当前控制器了。
textField,delegate=self;
然后我们在当前控制器实现下面三个委托方法:
- - (void)textFieldDidBeginEditing:(UITextField *)textField
- {
- NSTimeInterval animationDuration = 0.30f;
- CGRect frame = self.view.frame;
- frame.origin.y -=216;
- frame.size.height +=216;
- self.view.frame = frame;
- [UIView beginAnimations:@"ResizeView" context:nil];
- [UIView setAnimationDuration:animationDuration];
- self.view.frame = frame;
- [UIView commitAnimations];
- }
- - (BOOL)textFieldShouldReturn:(UITextField *)textField
- {
- NSTimeInterval animationDuration = 0.30f;
- CGRect frame = self.view.frame;
- frame.origin.y +=216;
- frame.size. height -=216;
- self.view.frame = frame;
-
- [UIView beginAnimations:@"ResizeView" context:nil];
- [UIView setAnimationDuration:animationDuration];
- self.view.frame = frame;
- [UIView commitAnimations];
- [textField resignFirstResponder];
- }
