+## setNativeProps to clear TextInput value
+
+Another very common use case of `setNativeProps` is to clear the value
+of a TextInput. The `controlled` prop of TextInput can sometimes drop
+characters when the `bufferDelay` is low and the user types very

+use `setNativeProps` to directly manipulate the TextInput value when
+necessary. For example, the following code demonstrates clearing the
+input when you tap a button:
+
+```javascript
+var App = React.createClass({
+  clearText() {
+    this._textInput.setNativeProps({text: ''});
+  },
+
+  render() {
+    return (
+      <View style={styles.container}>
+        <TextInput ref={component => this._textInput = component}
+                   style={styles.textInput} />
+        <TouchableOpacity onPress={this.clearText}>
+          <Text>Clear text</Text>
+        </TouchableOpacity>
+      </View>
+    );
