title: ProgressViewOffset for IOS Refresh Control React Native
body: <p>I have the header that hides on a scroll, So I use <code>ProgressViewOffset</code> to bring out refresh control loader below the header.<br>
  It's working fine on Android. But in IOS we have no support for offset. But I ended up using contentInset and contentOffset but I'm not getting it. </p>

  <pre><code>          refreshControl: (
          &lt;RefreshControl
            // refreshing
            refreshing={this.props.isloading}
            onRefresh={this.onRefresh}
            progressViewOffset={200}
            /&gt;
        ),
        contentInset: {top: 200},
        onMomentumScrollBegin,
        onMomentumScrollEnd,
        onScrollEndDrag,
        ItemSeparatorComponent: this.renderSeparator,
        onScrollEventThrottle: 16,
        automaticallyAdjustContentInsets: false, 
        contentOffset: {x: 0, y: -200},
  </code></pre>
  
  <p>PS: When I use contentContainerStyle and contentInset, There's a space between refreshcontrol and the content...</p>
