[iOS] app hang when include CJK characters multiline TextInput

[yangyi]

Description

when using CJK chars in multiline TextInput, app hangs, and unresponsive.

Reproduction Steps

paste sample code in any page of your app, and navigate to the page

Sample Code

export default class App extends React.Component {
  render() {
    const text = <Text>王者荣耀</Text>
    return (
      <View style={styles.container}>
        <TextInput multiline>
          {text}
        </TextInput>
      </View>
    );
  }

I also provide an git repo https://github.com/yangyi/demoinput

Solution

I replace NaN with CGFLOAT_MAX, that resolve the issue, but I'm not sure why this happens, and the solution is not well tested.
