方法1：通知中心

    [[NSNotificationCenter defaultCenter] addObserver:self                                             selector:@selector(textFieldEditChanged:)                                                 name:@"UITextFieldTextDidChangeNotification"                                               object:_inputTextField];

UIKIT_EXTERN NSString *const UITextFieldTextDidBeginEditingNotification;UIKIT_EXTERN NSString *const UITextFieldTextDidEndEditingNotification;UIKIT_EXTERN NSString *const UITextFieldTextDidChangeNotification;

- (void)textFieldEditChanged:(NSNotification *)obj{    UITextField *textField = (UITextField *)obj.object;    NSString *toBeString = textField.text;}

补充：获取键盘的模式

    NSString *lang = [[UITextInputMode currentInputMode] primaryLanguage]; // 键盘输入模式    if ([lang isEqualToString:@"：-Hans"]) {        UITextRange *selectedRange = [textField markedTextRange];        UITextPosition *position = [textField positionFromPosition:selectedRange.start offset:0];        if (!position) {        }else{        // 中文以外的输入法        }    }

补充：

#pragma mark - UITextFieldDelegate// 开始编辑键盘弹出的时候将组件向上移动  4s- (void)textFieldDidBeginEditing:(UITextField *)textField {    KTLog(@"%f",self.view.frame.size.height);    if (iPhone4s) {        if ([textField isEqual:_phoneNumTextField]) {            [UIView animateWithDuration:0.5 animations:^{                _tgView.frame = CGRectMake(SCREEN_WIDTH, -SCREEN_HEIGHT/5, SCREEN_WIDTH, SCREEN_HEIGHT);            }];        }    }}// 结束编辑键盘消失后将组件移到原来的位置- (void)textFieldDidEndEditing:(UITextField *)textField {    if (iPhone4s) {        if ([textField isEqual:_phoneNumTextField]) {            [UIView animateWithDuration:0.5 animations:^{                _tgView.frame = CGRectMake(SCREEN_WIDTH, 0, SCREEN_WIDTH, SCREEN_HEIGHT-54);            }];        }    }}
