一个简单易用的蓝牙设备操作库，基于CoreBluetooth框架

//导入.h文件和系统蓝牙库的头文件
#import <CoreBluetooth/CoreBluetooth.h>
#import "BabyBluetooth.h"

-(void)viewDidLoad {
    [super viewDidLoad];   

   //初始化BabyBluetooth 蓝牙库
    baby = [BabyBluetooth shareBabyBluetooth];
    //设置蓝牙委托
    [self babyDelegate];
    __weak typeof(baby) weakBaby = baby;
    //因为蓝牙设备打开需要时间，所以只有监听到蓝牙设备状态打开后才能安全的使用蓝牙
    [baby setBlockOnCentralManagerDidUpdateState:^(CBCentralManager *central) {
        if (central.state == CBCentralManagerStatePoweredOn) {
            //开始扫描设备
            weakBaby.scanForPeripherals().begin();
        }
    }];
}

//蓝牙网关初始化和委托方法设置
-(void)babyDelegate{
    //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);
    }];
}
