我关于信标的项目，当它最接近信标时显示图像，当它转到另一个信标时，它会显示另一个图像。我试图通过使用if语句来解决这个问题，我不知道该怎么做它给我看错误。
func locationManager(manager: CLLocationManager, didRangeBeacons beacons: [CLBeacon], inRegion region: CLBeaconRegion) {
if BEACON_1_UUID = BEACON_1_MAJOR {
var closestBeacon = beacons[0]
// print("major = \(closestBeacon.major) minor = \(closestBeacon.minor)")
if closestBeacon != lastFoundBeacon || lastProximity != closestBeacon.proximity {
lastFoundBeacon = closestBeacon
lastProximity = closestBeacon.proximity
var proximityMessage: String!
switch lastFoundBeacon.proximity {
case CLProximity.Immediate:
if BEACON_1_MAJOR = closestBeacon {
proximityMessage = "Very Close"
txtDesc.text = "hi"
imageview.image = UIImage(named: "CC_Zoe-Francois_No-Bake-Strawberry-Cheesecake.jpg");
self.checkIn("Leaving", comment: "Checking In")
self.view.backgroundColor = UIColor.redColor()
txtre.text! += "Very Close to \(closestBeacon.major) \(closestBeacon.minor) \n"
} else { /* ... */ }

default:

}
