is there a way to preselect items? about react-native-camera-roll-picker HOT 14 CLOSED

@jeanpan, there's another issue. The selected state is kept despite new selected props being passed in. perhaps it needs a componentWillReceiveProps to update state.

from react-native-camera-roll-picker.

@ndao. I will prepare a commit for preserving the state by passing an array of selected image as a props to the component and setting this props as the default value of selected state.

from react-native-camera-roll-picker.

@ndao. Now you can pass a selected array as a props to the component, as the example here https://github.com/jeanpan/react-native-camera-roll-picker/blob/master/Example/index.ios.js#L50 to preserve the selected state. Let me know if this solve your problem.

@jeanpan wow that was fast! thanks so much!
Question: in the latest version, the callback now returns an array of Objects whereas before it was returning an array of string. As they're objects now, this won't return the right index https://github.com/jeanpan/react-native-camera-roll-picker/blob/master/index.js#L159
to satisfy the selected state.
it is breaking for me. thoughts?

from react-native-camera-roll-picker.

@ndao. Yes, before the callback returns an array of string ( image uri ) but now it returns an array of Objects ( image object ). The indexOf works fine for me. Is your selected state a object array or a string array ? Could you please provide me your code so I can help you to fix the problem ?

from react-native-camera-roll-picker.

@jeanpan, i am basically using Redux to store the objects that returned from callback and pass it back again to CameraRollPicker component
Below is what the array of objects looks like

like so

<View
        style={{flex: 1, flexDirection: 'column'}}>
          <CameraRollPicker
            groupTypes='All'
            maximum={15}
            assetType='All'
            imagesPerRow={3}
            imageMargin={5}
            selectedMarker={<Marker />}
            selected={selected}
            callback={this.props.attachPhotos} />
      </View>

it also looks like the Camera component adds the selected array that i am passing in to its state (but not showing those images are selected). it then returns all the newly selected items PLUS the selected array items that was passed in.
