[Question] TabbarIOS.Item icon with image

[steve-ng]

How do I allow tabbarIOS.item to use my image?

Here's my code, I have an image called itemSelected

<TabBarIOS.Item       
  selected={this.state.selectedTab === 'Item'}      
  icon={require('image!itemNotSelected')}       
  selectedIcon={require('image!itemSelected')}       
 title="Item"       
 onPress={() => { this.setState({ selectedTab: 'Item',});}}

However, I can only see a square box being loaded from react-native in my tabbar.

it's working, except that my image needed to have transparent area.
