title: Trying to clear input placeholder on focus/touch
body: <p>This is my code:</p>
  
  <pre><code>&lt;TextInput value={this.state.task} underlineColorAndroid={'transparent'} placeholder = {'+ הוסף משימה חדשה'}
              style={styles.input}
              onChangeText={(text) =&gt; {
                this.setState({task: text});
              } }
              onEndEditing={()=&gt; this.addTask()}
              /&gt;
  </code></pre>
  
  <p>Not sure how I can do this. Hope someone can help. Thanks!</p>
