主要思路

虽然苹果官方的API没有获取Mac地址的方法，但是当我翻看蓝牙的文档的时候，我发现蓝牙有提供一个设备信息的service［service UUID：0x180A］,里面提供了两个characteristic：获取芯片的Mac地址（0x2A23 ）和获取软件的版本号（0x2A26）。如下图所示：
这里写图片描述

实现

根据这个思路：

[peripheral discoverServices:@[[CBUUID UUIDWithString:@"180A"]]];[service discoverCharacteristics:@[[CBUUID UUIDWithString:@"2A23"]]];[peripheral readValueForCharacteristic:characteristic]NSString *value = [NSString stringWithFormat:@"%@",characteristic.value];NSMutableString *macString = [[NSMutableString alloc] init];[macString appendString:[[value substringWithRange:NSMakeRange(16, 2)] uppercaseString]];[macString appendString:@":"];[macString appendString:[[value substringWithRange:NSMakeRange(14, 2)] uppercaseString]];[macString appendString:@":"];[macString appendString:[[value substringWithRange:NSMakeRange(12, 2)] uppercaseString]];[macString appendString:@":"];[macString appendString:[[value substringWithRange:NSMakeRange(5, 2)] uppercaseString]];[macString appendString:@":"];[macString appendString:[[value substringWithRange:NSMakeRange(3, 2)] uppercaseString]];[macString appendString:@":"];[macString appendString:[[value substringWithRange:NSMakeRange(1, 2)] uppercaseString]];//00:E0:4C:3F:14:DE

这里可一个大家推荐一个非常好用的蓝牙开发的库，跟CoreBluetooth的接口一摸一样，只是数据是用过block返回的，用起来更加的方便。

MPBluetoothKit

下面是写的MPBluetoothKit 获取Mac地址的代码

CBUUID *macServiceUUID = [CBUUID UUIDWithString:@"180A"];    CBUUID *macCharcteristicUUID = [CBUUID UUIDWithString:@"2A23"];    [mPeripheral discoverServices:@[macServiceUUID] withBlock:^(MPPeripheral *peripheral, NSError *error) {        if(peripheral.services.count){            MPService *service = [peripheral.services objectAtIndex:0];            [service discoverCharacteristics:@[macCharcteristicUUID] withBlock:^(MPPeripheral *peripheral, MPService *service, NSError *error) {                for(MPCharacteristic *characteristic in service.characteristics){                    if([characteristic.UUID isEqual:macCharcteristicUUID]){                        [characteristic readValueWithBlock:^(MPPeripheral *peripheral, MPCharacteristic *characteristic, NSError *error){                            NSString *value = [NSString stringWithFormat:@"%@",characteristic.value];                            NSMutableString *macString = [[NSMutableString alloc] init];                            [macString appendString:[[value substringWithRange:NSMakeRange(16, 2)] uppercaseString]];                            [macString appendString:@":"];                            [macString appendString:[[value substringWithRange:NSMakeRange(14, 2)] uppercaseString]];                            [macString appendString:@":"];                            [macString appendString:[[value substringWithRange:NSMakeRange(12, 2)] uppercaseString]];                            [macString appendString:@":"];                            [macString appendString:[[value substringWithRange:NSMakeRange(5, 2)] uppercaseString]];                            [macString appendString:@":"];                            [macString appendString:[[value substringWithRange:NSMakeRange(3, 2)] uppercaseString]];                            [macString appendString:@":"];                            [macString appendString:[[value substringWithRange:NSMakeRange(1, 2)] uppercaseString]];                            NSLog(@"macString:%@",macString);                        }];                    }                }            }];        }    }];
