+# IMUICustomInputView
+
+from [0.10.0 Version] you can use ```IMUICustomInputView ``` to customize you inputView. ```IMUIInputView``` is basic in ```IMUICustomInputView```. You can use ```IMUICustomInputView``` to put anything into inputTextView's left/right/bottom position,and put anything into inputView's FeatureView. and it is easy used, just like ```UICollectionView``` or ```UITableView``` .You need implement ```IMUICustomInputViewDataSource``` and ```IMUICustomInputViewDelegate``` protocol.
+
+### Usage:
+
+**Setp one:** drag a view to your UIViewController (storyboard or xib), and adjust class to ```IMUICustomInputView```,and set customInput's delegate and dataSource.
+**Setp two:** implement ```IMUICustomInputViewDataSource```
+
+- return left/right/bottom inputBarItemListView's item number
+
+  ```
+  func imuiInputView(_ inputBarItemListView: UICollectionView,
+                             numberForItemAt position: IMUIInputViewItemPosition) -> Int
+  ```
+
+- retuen left/right/bottom inputBarItemListView's item size
+
+  ```
+  func imuiInputView(_ inputBarItemListView: UICollectionView,
+                             _ position: IMUIInputViewItemPosition,
+                             sizeForIndex indexPath: IndexPath) -> CGSize
+  ```
+
+- return left/right/bottom inputBarItemListView's item cell
+
+  ```
+  func imuiInputView(_ inputBarItemListView: UICollectionView,
+                             _ position: IMUIInputViewItemPosition,
+                             cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
+  ```
+
+- return featureView's cell
+
+  ```
+  func imuiInputView(_ featureView: UICollectionView,
+                             cellForItem indexPath: IndexPath) -> UICollectionViewCell
+  ```
+
+**Setp three:** implement ```IMUICustomInputViewDelegate```
+
+- Tells the delegate when inputTextview text did change
+
+  ```
+  optional func textDidChange(text: String)
+  ```
+
+- Tells the delegate when keyboard will show
+
+  ```
+  optional func keyBoardWillShow(height: CGFloat, durationTime: Double)
+  ```
+
+### API:
+
+##### register
+
+- register ```UICollectionViewCell``` to specified position, The usage just like ```UICollectionView```. there are two register function:
+
+```
+// register cell with class
+public func register(_ cellClass: AnyClass?, in position: IMUIInputViewItemPosition, forCellWithReuseIdentifier identifier: String) {  }
+
+// register cell with nib
+public func register(_ nib: UINib?,in position: IMUIInputViewItemPosition, forCellWithReuseIdentifier identifier: String) {  }
+```
+
+example:
+
+```
+  customIntputView.self.register(
+          UINib(nibName: "IMUIFeatureListIconCell", bundle: bundle), 
+          in: .bottom, 
+          forCellWithReuseIdentifier: "IMUIFeatureListIconCell"
+  		)
+  
+  func imuiInputView(_ inputBarItemListView: UICollectionView,
+                     _ position: IMUIInputViewItemPosition,
+                     cellForItemAt indexPath: IndexPath) -> UICollectionViewCell 
+  {
+       switch position {
+        case .bottom:
+          let cell = inputBarItemListView.dequeueReusableCell(
+          withReuseIdentifier: cellIdentifier, 											
+          for: indexPath)
+        default:
+        break
+        }
+  }
+```
+
+- featureView also need to register ```UICollectionViewCell ``` to featureView, there are two register function:
+
+  ```
+  // register cell with class
+  public func registerForFeatureView(_ cellClass: AnyClass?, 
+           forCellWithReuseIdentifier identifier: String) {  }
+
+  // register cell with nib
+  public func registerForFeatureView(_ nib: UINib?, 
+     forCellWithReuseIdentifier identifier: String) {  }
+  ```
+
+  example:
+
+  ```
+  customInputView.registerForFeatureView(
+  		UINib(nibName: "IMUIRecordVoiceCell", bundle: bundle),
+           forCellWithReuseIdentifier: "IMUIRecordVoiceCell"
+         )
+         
+  func imuiInputView(_ featureView: UICollectionView,
+               cellForItem indexPath: IndexPath) -> UICollectionViewCell {
+    let cell = featureView.dequeueReusableCell(
+            withReuseIdentifier: CellIdentifier, 
+            for: indexPath
+    		)
+  }
+  ```
+
+##### update inputView's item(inputBar' cell and FeatureView's cell)
+
+Sometime you need to update inputView's item(ex: if textView's text is empty, you want to set send button's color to gray that mean the button is unable to click), You can use the following methods：
+
+```
+//update inputBar's item
+public func updateInputBarItemCell(_ position: IMUIInputViewItemPosition,
+                                     at index: Int)
+                                     
+//update featureView's content，
+public func reloadFeaturnView()
+```
+
+##### show featureView
+
+```
+customInputView.showFeatureView()
+```
+
+##### hidden featureView
+
+```
+customInputView.hideFeatureView()
+```
+
