CBCentralManager

Initializing a Central Manager

- (instancetype)initWithDelegate:(id<CBCentralManagerDelegate>)delegate queue:(dispatch_queue_t)queue//建立Center
- (instancetype)initWithDelegate:(id<CBCentralManagerDelegate>)delegate queue:(dispatch_queue_t)queue options:(NSDictionary *)options

Establishing or Canceling Connections with Peripherals

- (void)connectPeripheral:(CBPeripheral *)peripheral options:(NSDictionary *)options//启动连接某设备
- (void)cancelPeripheralConnection:(CBPeripheral *)peripheral//断开连接

Retrieving Lists of Peripherals

- (void)retrieveConnectedPeripherals//获取已经连接的设备。回调centralManager:didRetrieveConnectedPeripherals。如果与其他Center连接也会获得。
- (NSArray *)retrieveConnectedPeripheralsWithServices:(NSArray *)serviceUUIDs//直接返回peripherals列表，无需回调。IOS7新增以取代上个方法。
- (void)retrievePeripherals:(NSArray *)peripheralUUIDs//根据UUID获得设备。回调centralManager:didRetrievePeripherals。
- (NSArray *)retrievePeripheralsWithIdentifiers:(NSArray *)identifiers//直接返回peripherals列表。 

 

Scanning or Stopping Scans of Peripherals

- (void)scanForPeripheralsWithServices:(NSArray *)serviceUUIDs options:(NSDictionary *)options//启动扫描。回调diddiscover
- (void)stopScan//停止扫描

Monitoring Properties

@property(readonly) CBCentralManagerState state//状态。系统调用centralManagerDidUpdateState更新状态。主要为当前蓝牙状态。
@property(weak, nonatomic) id< CBCentralManagerDelegate > delegate
