How to zoom in/out in react-native-map?
问题 I am using react-native to build a map application. The api I am using is from this link: https://github.com/lelandrichardson/react-native-maps. Below is the code I bring the map on my app. I wander how I can give a zoom value on that map. And how I can change the zoom value when user click a button on the map. What is the zoom API I should use to achieve this? import React, { AppRegistry, Component, StyleSheet, Text, View, Image, ListView, TextInput, TouchableHighlight, Dimensions, //MapView
