iBeacon 和 BLE 的差異
1. Use Core Location framework to find iBeacon's distance.
使用CLLocationManagerDelegate 抓取Beacon 和裝置間的距離

2. Use Core Bluetooth framework to communicate with BLE device.
在架構中有分Centrals(手機端) 和 Peripherals(裝置端) , Centrals 由CBCentralManager 這個物件來管理和Peripherals連線的事宜. 而裝置端則是 CBPeripheral . CBPeripheral 下會有 CBService 代表不同的服務.
以上使用時需用到 CBCentralManagerDelegate, CBPeripheralDelegate 這兩個delegate.
例如在CBCentralManagerDelegate內有 centralManager(_:didDiscover:advertisementData:rssi:) 這個method, 透過rssi 我們可以知道裝置連線的訊號強弱判斷與裝置間的距離.

使用CLLocationManagerDelegate 抓取Beacon 和裝置間的距離
// Delegate method from the CLLocationManagerDelegate protocol. |
- (void)locationManager:(CLLocationManager *)manager |
didRangeBeacons:(NSArray *)beacons |
inRegion:(CLBeaconRegion *)region {
|
if ([beacons count] > 0) {
|
CLBeacon *nearestExhibit = [beacons firstObject]; |
// Present the exhibit-specific UI only when |
// the user is relatively close to the exhibit. |
if (CLProximityNear == nearestExhibit.proximity) {
|
[self presentExhibitInfoWithMajorValue:nearestExhibit.major.integerValue]; |
} else {
|
[self dismissExhibitInfo]; |
} |
} |
