#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

<br> **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：

<br>

一个页面内多个输入控件处理：(可逐个传入，可传入共同superView)
<br> <br>

UITextView处理：
<br> <br>

#CocoaPods：
pod 'ZYKeyboardUtil', '~> 1.0.7'

<br>

#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];
}];

or you can write like this convenient: (KeyboardUtil can find the controller itself)

__weak ViewController *weakSelf = self;
[_keyboardUtil setAnimateWhenKeyboardAppearAutomaticAnimBlock:^(ZYKeyboardUtil *keyboardUtil) {
    [keyboardUtil adaptiveViewHandleWithAdaptiveView:weakSelf.inputViewOne, weakSelf.inputViewSecond, weakSelf.inputViewThird, weakSelf.inputViewFourth, nil];
}];
<br> **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  
- heightIncrement：单次键盘变化增量  
- action：键盘事件枚举  
- isSameAction：是否同一种动作    

**func：**  
- fillKeyboardInfoWithDuration:frameBegin:frameEnd:heightIncrement:action:isSameAction:    
为KeyboardInfo各属性赋值。

- keyboardInfo  
- haveRegisterObserver：是否已经注册监听者  
- animateWhenKeyboardAppearBlock：弹出Block  
- animateWhenKeyboardDisappearBlock：收起Block  
- printKeyboardInfoBlock：输出键盘信息Block    
- animateWhenKeyboardAppearBlockAutomaticAnim：全自动处理键盘遮盖事件Block   
**func：**  
- setAnimateWhenKeyboardAppearBlock:    
- setAnimateWhenKeyboardDisappearBlock:  
- setPrintKeyboardInfoBlock:    
- setAnimateWhenKeyboardAppearBlockAutomaticAnim:
