Gyroscope Iphone camera controls not working in 4.5

Questions & Answers
1

The script that I was using to control the camera with my iphone’s gyroscope seems to have broken when upgrading to 4.5. It works perfectly when testing with unity remote 4 but does not load up when pushed from xcode despite no errors or warnings. Any Insight?
I originally found the script here.

// Directions: Attach this script to main camera.
// Note: Unity Remote does not currently support gyroscope. 

private var gyroBool : boolean;
private var gyro : Gyroscope;
private var rotFix : Quaternion;

function Start() {
	
	var originalParent = transform.parent; // check if this transform has a parent
	var camParent = new GameObject ("camParent"); // make a new parent
	camParent.transform.position = transform.position; // move the new parent to this transform position
	transform.parent = camParent.transform; // make this transform a child of the new parent
	camParent.transform.parent = originalParent; // make the new parent a child of the original parent
	
	gyroBool = SystemInfo.supportsGyroscope;
	
	if (gyroBool) {
		
		gyro = Input.gyro;
		gyro.enabled = true;
		
		if (Screen.orientation == ScreenOrientation.LandscapeLeft) {
			camParent.transform.eulerAngles = Vector3(90,90,0);
		} else if (Screen.orientation == ScreenOrientation.Portrait) {
			camParent.transform.eulerAngles = Vector3(90,180,0);
		}
		
		if (Screen.orientation == ScreenOrientation.LandscapeLeft) {
			rotFix = Quaternion(0,0,0.7071,0.7071);
		} else if (Screen.orientation == ScreenOrientation.Portrait) {
			rotFix = Quaternion(0,0,1,0);
		}
		//Screen.sleepTimeout = 0;
	} else {
		print("NO GYRO");
	}
}

function Update () {

		var camRot : Quaternion = gyro.attitude * rotFix;
		transform.localRotation = camRot;

I got it working using this script. `#pragma strict

static var gyroBool : boolean;
private var gyro : Gyroscope;
private var quatMult : Quaternion;
private var quatMap : Quaternion;
private var camGrandparent : GameObject;
function Awake() {
// find the current parent of the camera’s transform
var currentParent : Transform = transform.parent;
// instantiate a new transform
var camParent : GameObject = new GameObject(“camParent”);
// match the transform to the camera position
camParent.transform.position = transform.position;
// make the new transform the parent of the camera transform
transform.parent = camParent.transform;

// Also creates a grandparent (camGrandparent) which can be rotated with localEulerAngles.y
// This node allows an arbitrary heading to be added to the gyroscope reading
// so that the virtual camera can be facing any direction in the scene, no matter what the phone's heading
camGrandparent = new GameObject("camGrandParent");
// match the transform to the camera position
camGrandparent.transform.position = transform.position;
// make the new transform the parent of the camera transform
camParent.transform.parent = camGrandparent.transform;
// make the original parent the grandparent of the camera transform
camGrandparent.transform.parent = currentParent;

// check whether device supports gyroscope
gyroBool = SystemInfo.supportsGyroscope;

if (gyroBool) {
    gyro = Input.gyro;
    gyro.enabled = true;
 
    #if UNITY_IPHONE
        camParent.transform.eulerAngles = Vector3(90, 90, 0);
        quatMult = Quaternion(0, 0, 1, 0);
    #endif
 
    Screen.sleepTimeout = SleepTimeout.NeverSleep;
} else {
    print("NO GYRO");
}

}

function Start() {
// First, check if user has location service enabled
if (!Input.location.isEnabledByUser)
return;

// Start service before querying location
Input.location.Start();
Input.compass.enabled = true;

// Wait until service initializes
var maxWait : int = 20;
while (Input.location.status == LocationServiceStatus.Initializing && maxWait > 0) {
    yield WaitForSeconds(1);
    maxWait--;
}

if (maxWait < 1) {
    // Service didn't initialize in 20 seconds
    print("Timed out");
    return;
}

if (Input.location.status == LocationServiceStatus.Failed) {
    // Connection has failed
    print("Unable to determine device location");
    return;
}

}
function Update() {
if (gyroBool) {
#if UNITY_IPHONE
quatMap = gyro.attitude;
#endif

    camGrandparent.transform.localEulerAngles.y = Input.compass.trueHeading;
    transform.localRotation = quatMap * quatMult;
}

}
