委托设置

baby的使用分为2步。设置block委托和调用方法 每次调用方法后，都会进入到相应的委托方法。每个方法对应的委托见“用法示例”

示例

  //设置扫描到设备的委托
    [baby setBlockOnDiscoverToPeripherals:^(CBCentralManager *central, CBPeripheral *peripheral, NSDictionary *advertisementData, NSNumber *RSSI) {
        NSLog(@"搜索到了设备:%@",peripheral.name);
    }];
    //设置设备连接成功的委托
    [baby setBlockOnConnected:^(CBCentralManager *central, CBPeripheral *peripheral) {
        //设置连接成功的block
        NSLog(@"设备：%@--连接成功",peripheral.name);
    }];
    

设置委托方法后执行

baby.scanForPeripherals().begin();

每当发现perihperal和连接成功后就会进入相应的委托方法。

委托方法的频道channel

委托方法的设置可以通过channel区分开来.

对于项目中多个类需要使用蓝牙这种情况，常规做法是你实例化出多个CBCentralManager,并分别设置CBCentralManager和CBPeripheral的委托，这种用法超级啰嗦和麻烦。不过使用BabyBluetooth,可以仅使用一个BabyBluetooth的实例，通过setBlockOn...AtChannel的方法设置不同channel的委托方法，并使用baby.channel(channelName)的方法切换到这个channelName的委托。

示例：

    //设置channel “detailsView” 频道上 ， 扫描到设备的委托
    NSString *channelName = @"detailsChannel";
    [baby setBlockOnDiscoverToPeripheralsAtChannel:channelName
          block:^(CBCentralManager *central, CBPeripheral *peripheral, NSDictionary *advertisementData, NSNumber *RSSI) {
         NSLog(@"channel(%@) :搜索到了设备:%@",channelName,peripheral.name);
    }];
    
    //切换到委托频道
    baby.channel(channelName)
    //扫描设备并开始执行
    .scanForPeripherals().begin();
    

##默认频道 在 baby.().().()链式函数体中，channel()可以放在.begin()之前的任意位置。若链式函数体中不包含.channel()方法或是channelName为nil时，会切换到默认频道。
