从键盘事件（比如UIKeyboardWillShowNotification）中，得不到使用是哪个输入法。只能得到类似下面的信息：
{
UIKeyboardAnimationCurveUserInfoKey = 7;
UIKeyboardAnimationDurationUserInfoKey = 0;
UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 216}}";
UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 568}";
UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 460}";
UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 568}, {320, 0}}";
UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 352}, {320, 216}}";
}
所以感觉使用正常渠道可能得不到这个信息，不过使用私有API可以获取得到当前输入法的Id:
UIKeyboardInputModeController *key = [UIKeyboardInputModeController sharedInputModeController];
//当前输入法
UIKeyboardInputMode *currentInputMode = [key currentInputMode];
//第三方扩展输入法
NSArray *extensionInputModes = [key extensionInputModes];
if ([extensionInputModes containsObject:currentInputMode]) {
NSLog(@"current input mode (%@) is the 3rd party input mode", currentInputMode.identifier);
} else {
NSLog(@"current input mode (%@) is build-in input mode", currentInputMode.identifier);
}
输出大概是这样的：
current input mode (com.cleanshavenapps.Pasteboard.PasteboardKeyboard) is the 3rd party input mode
current input mode (com.sogou.sogouinput.basekeyboard) is the 3rd party input mode
current input mode (com..inputMethod.keyboard) is the 3rd party input mode
current input mode (en_US@hw=US;sw=QWERTY) is build-in input mode
current input mode (zh_Hans-Pinyin@sw=Pinyin10-Simplified;hw=US) is build-in input mode
current input mode (emoji@sw=Emoji) is build-in input mode
有三个是系统自带的，三个是第三方的。
共涉及到两个私有API类：分别是，UIKeyboardInputModeController 和 UIKeyboardInputMode。
这是我的头文件，你放入工程就可以用了：

在应用中我们常常自定义键盘，特别是为数字键盘增加新的功能按钮；现在越来越多的输入法支持iphone，百度。腾讯，搜狐等；
如用户安装了第三方的输入法，我们就需要辨别出来：
在IOS 4.2以上支持 UITextInputMode，可通过 [[UITextInputMode currentInputMode] primaryLanguage] 来获取当前输入法，如果是自定义的这里会显示自定义信息（例如：。。）但是如何更好的识别呢，暂时也没有找到令我满意的方式：
需要知道的：
普通的数字键盘弹出时，打印[[UITextInputMode currentInputMode] primaryLanguage] 跟当前语言相关，比如当前语言为en，打印所得是en-US；当前语言是zhhhans，打印所得是zh-hans;若改数字键盘是密码键盘形式，打印所得都是en-US;
暂时可以通过以下方式解决：
1、获取系统设置里当前语言，例如ja(日语)，可通过判断primaryLanguage 是否为en－US或者primaryLanguage是否包含前缀ja（注：primaryLanguage 与当前语言并不完全相同）；若不满足前两个条件，则应该是第三方输入法；（这种方式也可能会有问题，加入除了一个输入法，名字是japan，谁知道呢？？）
2、[UITextInputMode activeInputModes]，另外一个规律是，如果是系统输入法获取的这个数组中有包含一个keyboardmode对象，而出现第三方输入法键盘时，包含两个keyboardmode对象，不知道算不算规律，暂时来看也是一种方法吧；
暂时采用的第一种方式，感觉更有依据性一些，如果有更好的方法，欢迎分享
