ZYKeyboardUtil
Util Handed all keyboard events with Block Conveniently
只需要一个Block，全自动处理任何多层嵌套复杂界面 因键盘升降 造成的输入控件遮挡问题。
第三方键盘分次弹出问题
- 0.4.1支持一个页面多个输入控件处理(全自动处理键盘升降遮挡输入控件问题) (仅需配置animateWhenKeyboardAppearAutomaticAnimBlock) - 0.3.1更新自动处理键盘收起时对界面的还原(需与全自动升起处理同时使用， 无需配置animateWhenKeyboardDisappearBlock) - 0.2.1更新全自动处理键盘遮盖事件(需配置animateWhenKeyboardAppearAutomaticAnimBlock),具体使用参照Demo
#Features：
第三方键盘分次弹出问题：
ZYKeyboardUtil 通过对每次键盘展开时的增量heightIncrement作处理 应对 第三方键盘 分次弹出的问题
**同时能处理多层嵌套情况下控件的键盘遮盖问题** UITextField嵌套两层UIView例子演示：
一个页面内多个输入控件处理：
#CocoaPods：
pod 'ZYKeyboardUtil', '~> 0.4.1'
#Usage：
创建一个ZYKeyboard对象，为了让其生存在整个页面实现功能的时间段内，让你的controller持有他吧。
self.keyboardUtil = [[ZYKeyboardUtil alloc] init];配置animateWhenKeyboardAppearAutomaticAnimBlock，即可全自动处理键盘升降遮挡输入控件问题，且控件resignFirstResponder后自动还原。
只需在Block里利用参数keyboardUtil调用adaptiveViewHandleWithController:adaptiveView:，第一个参数为当前页面controller，第二个参数接收一个可变参数，为当前页面内的单个/多个输入控件或者包裹输入控件的View。
__weak ViewController *weakSelf = self;
[_keyboardUtil setAnimateWhenKeyboardAppearAutomaticAnimBlock:^(ZYKeyboardUtil *keyboardUtil) {
[keyboardUtil adaptiveViewHandleWithController:weakSelf adaptiveView:weakSelf.inputViewOne, weakSelf.inputViewSecond, weakSelf.inputViewThird, weakSelf.inputViewFourth, nil];
}];**Attach：** 另外提供自定义处理键盘升/降遮挡输入控件处理(自定义处理方案优先级高于自动处理方案)： ```objc [_keyboardUtil setAnimateWhenKeyboardAppearBlock:^(int appearPostIndex, CGRect keyboardRect, CGFloat keyboardHeight, CGFloat keyboardHeightIncrement) { //do something when keyboard appear }];
[_keyboardUtil setAnimateWhenKeyboardDisappearBlock:^(CGFloat keyboardHeight) { //do something when keyboard dismiss }];
[_keyboardUtil setPrintKeyboardInfoBlock:^(ZYKeyboardUtil *keyboardUtil, KeyboardInfo *keyboardInfo) { //you can get keyboardInfo hear when animation ended }];
<br>
#**explain：**
ZYKeyboardUtil 通过lazy方式注册键盘通知监听者，核心工作围绕一个model和四个Block(一个主功能Block和三个附加Block)，内部类KeyboardInfo作为model存储着每次处理时所需的键盘信息。animateWhenKeyboardAppearAutomaticAnimBlock作全自动处理，animateWhenKeyboardAppearBlock作键盘展示时的处理，animateWhenKeyboardDisappearBlock作键盘收起时的处理，而printKeyboardInfoBlock用作在必要时输出键盘信息。AppearBlock和DisappearBlock统一做了UIViewAnimation，自定义处理事件时只需要编写需要的界面变化即可。

###Class：
####-KeyboardInfo:
**property：**
- animationDuration: 响应动画的过程时长
- frameBegin：触发键盘事件前键盘frame
- frameEnd：变化后键盘frame
