iOS Issue When Calling Tweet From Modal

[angusmccloud]

I'm using SocialShare on both iOS and Android for the Twitter side of Social integration (using the FBSDK for that piece), and have found that on iOS the Twitter dialog box doesn't doesn't appear if my tweet function is called from a button in a Modal.

If I put a flat button on the screen it will work every time, but in a Modal it doesn't.

At this point I've disabled the modals that see if people want to post to social media, but that's really disappointing since it's a great way to prompt people when certain events happen.

Has anyone else run into this?

@angusmccloud Hey Connor

I am quite sure this behavior happens because the share dialog is a modal of some sort itself. Maybe you could fix it by making the button first close down the modal and then trigger the social share.

@doefler I should have shared some code! Yes, that was my first guess and so I have things structured like this:

  tweet(){
    this.setSocialMediaModal(false); // this true/false powers the Visible property on the Modal
    var text = this.getTwitterText(); // Pulls a random string to have as the default text (that fits within the 140 characters)
    if(this.props.PublishedFlag == "1"){ // Should we share a link to the content (is it a publicly accessible URL)
      var link = this.props.ProfileURL;
    }
    else{
      var link = null;
    }
    if(this.props.BeerImage == "noimage.jpg"){ // Is there an image to share
//      console.log("Beer has no image");
      var imageLink = null;
    }
    else{
//      console.log("Beer has an image");
      var imageLink = GLOBAL.beer_image_base_url + this.props.BeerImage;
    }
//    console.log("Text: " + text + ", link: " + link + ", Image: " + imageLink);
    shareOnTwitter({
        'text':text,
        'link':link,
        'imagelink':imageLink,
      },
      (results) => {
.....
//        console.log(results);
      }
    );
  }

Can you share the rest of this file? Do you bind "this" to the event? onClick={this.onClickHandler.bind(this)} for example.

Does the console tell anything?

@doefler

Can you share the rest of this file? I can share that relevant section (this screen is the most complex and longest within the app).

Do you bind "this" to the event? No, the setSocialMediaModal is not bound, I can try that tonight.

Does the console tell anything? No, but that's because I do all of this on a PC and this works 100% of the time on Android. I'll steal my wife's macbook and see if the log tells me anything. I DO know that iOS will crash if you try to open multiple modals/alerts, and Android doesn't. But this method of "close the one that's open before opening the next" has worked for me everywhere else in the app.

Code for that component (with unrelated pieces "..." out):

class RenderButtons extends Component {
  constructor() {
    super();
    this.state = {
      socialMediaModal: false,
      ...
    }
  }

  async componentWillMount(){
	... // Fetching some asyncStorage info, not relevant to Twitter
    this.CheckOut = this.CheckOut.bind(this);
  }

  CheckOut(){
    this.setState({checkedInFlag: false});
  }

  removeImage() {
    ...
  }

  startImagePicker() {
    ...
  }

  render(){
    var dataFetching = this.props.dataFetching;
    ... // Other unrelated variables

    if (dataFetching === false) {
      ...

      return(
        <View>

I would try changing:

<View style={{padding: 10}}>
	<Button
		onPress = { () => this.tweet() }
		title = "Post to Twitter"
		color = {COLOR_DEFAULT_ORANGE}
		accessibilityLabel = "Post to Twitter"
	/>
</View>

into

<View style={{padding: 10}}>
	<Button
		onPress = { this.tweet.bind(this) }
		title = "Post to Twitter"
		color = {COLOR_DEFAULT_ORANGE}
		accessibilityLabel = "Post to Twitter"
	/>
</View>

Notice the onPress part.

Other than that, I don't have any idea, what might cause this.
