An example gist trying to show how to implement an icon within a tcomb form in react-native

iconExample.js

const Form = t.form.Form;

const postOptions = t.struct({
    publication: t.String,
    tags: t.String,
    more: t.String,
    facebook: t.Boolean
})

const options = {
    fields: {
        publication: {
            placeholder: "Add to Publication",
            template: template,
            config: { icon: 'plus' }
        },
        tags: {
            placeholder: "Add tags",
            template: template,
            config: { icon: 'tag' }
        },
        more: {
            placeholder: "More Options",
            template: template,
            config: { icon: 'info' }
        }
    }
};

function template(locals) {

    var containerStyle = { ... };
    var labelStyle     = { ... };
    var textboxStyle   = { ... };

    return (
        <View style={containerStyle}>
            <Icon name={locals.config.icon} style={labelStyle} size={15} />
            <TextInput style={textboxStyle} placeholder={locals.placeholder} />
        </View>
    );

}

....

<Form
    ref="postOptions"
    type={postOptions}
    options={options}
/>
