RESOLVED : My setState function is not working on IOS

I recently tested my react native app on IOS and saw a strange bug : One of my setState call do not update my state, and i checked if everything else was correct.

I'm working on a real estate selling application. This setState was meant to, on a map, when the user click on a marker, shows a box of the estate clicked with detailled informations. So when a user click, it get the index of the estate clicked, and fill a state var currentEstate with it.

Furthemore it appears only on IOs, on Android everything is working fine, any ideas ?

Here's the code :

My toggle estate function, which contains the setState

  _toggleEstate(index, coords) {    // This is what i want to put in my currentEstate, and it's not empty    console.log(this.state.estates[index]);    this.setState(      {        currentEstate: this.state.estates[index]      },      function() {        // But this is empty, so the setState didn't work        console.log(this.state.currentEstate);      }    );    var newRegion = {      latitude: coords.latitude,      longitude: coords.longitude,      latitudeDelta: 0.00522,      longitudeDelta: 0.0221    };    this.mapRef.animateToRegion(newRegion, 500);  }

My renderEstate function which check if the currentEstate is empty and return a JSX component if not :

  _renderEstateItem() {    if (this._isEmpty(this.state.currentEstate)) {      return null;    } else {      return (<View style={styles.estateContainer}><EstateItem            estate={this.state.currentEstate}            displayDetailForEstate={this._displayDetailForEstate}            showImage={false}          /></View>      );    }  }

And my JSX component :

  render() {    return (<View style={styles.mainContainer}><MapView          initialRegion={{            latitude: 48.8691526048,            longitude: 2.352065575453187,            latitudeDelta: 0.1922,            longitudeDelta: 0.0421          }}          ref={ref => {            this.mapRef = ref;          }}          onPress={() => this._clickOnMap()}          style={{ flex: 1 }}>          {this.state.markers.map((marker, index) => {            const coords = {              latitude: marker.lat,              longitude: marker.lng            };            return (<MapView.Marker                key={index}                coordinate={coords}                title={this.state.estates[index].adress}                description={                  numeral(this.state.estates[index].price)                    .format("0,0")                    .replace(",", "") +"€"                }                pinColor={color.electricViolet}                onPress={() => this._toggleEstate(index, coords)}              />            );          })}</MapView><TouchableOpacity          onPress={() => this._goToList()}          style={            this._isEmpty(this.state.currentEstate)              ? styles.listButton              : styles.listButtonUp          }><Image            style={styles.listIcon}            resizeMode="contain"            source={require("../assets/images/purple_icons/List.png")}          /></TouchableOpacity>        // Here it is when it's suppose to render        {this._renderEstateItem()}        {this._displayLoading()}</View>    );  }

And finally the constructor :

  constructor(props) {    super(props);    this.mapRef = null;    this.myResearch = this.props.navigation.state.params.myResearch;    this.state = {      isLoading: false,      estates: [],      markers: [],      currentEstate: []    };    Geocoder.init(constants.GOOGLE_MAPS_API);    this._displayDetailForEstate = this._displayDetailForEstate.bind(this);  }

Thanks in advance !
