[蓝牙]CoreBluetooth获取蓝牙设备UUID

更多智能设备开始脱离音频口，改用蓝牙4.0。【iPhone 4S，iOS 7 以上设备】
所以接入产商SDK的时候，需要自行匹配蓝牙模块的UUID。

1）导入CoreBluetooth.framework
2）加入头#import “CoreBluetooth/CoreBluetooth.h”
3）引入协议
4）看下面代码：
[objc]
@interface BlueSearchViewCtrl : UIViewController<CBCentralManagerDelegate,CBPeripheralDelegate>{

NSMutableArray *blueDevs,*nameDevs;//用于存放蓝牙UUID，用于存放设备名，也可直接整成Arr+Dict
CBCentralManager *centralMgr;

}
[/objc]
5）创建事例，初始化2动态数组
[objc]
centralMgr = [[CBCentralManager alloc] initWithDelegate:self queue:nil];

nameDevs = [NSMutableArray new];
[nameDevs addObject:@">>退出蓝牙匹配"];

blueDevs = [NSMutableArray new];
[/objc]
6) 查找设备
[objc]
– (void)centralManagerDidUpdateState:(CBCentralManager *)central{

switch (central.state) {
case CBCentralManagerStatePoweredOn:{
//这个字典，主要用来过滤不要出现重复情况，不然会不停的添加进来；当然下面options:直接nil也行；
NSDictionary * tempDict = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:NO],CBCentralManagerScanOptionAllowDuplicatesKey, nil];
[centralMgr scanForPeripheralsWithServices:nil options:tempDict];
}break;

default:
NSLog(@"Central Manager State Other");
break;
}

}
[/objc]
7）设备回调
[objc]
– (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI
{
[nameDevs addObject:peripheral.name];
[blueDevs addObject:peripheral.identifier.UUIDString];
UITableView *table = (UITableView*)[self.view viewWithTag:1];
[table reloadData];
NSLog(@"name : %@", peripheral.name);
NSLog(@"identifier : %@", peripheral.identifier.UUIDString);

}
[/objc]
8）由于接入产商只要得到UUID即可，后面部分就略了。
9）关于连接蓝牙，与回调
[objc]
[centralMgr connectPeripheral:peripheral options:
[NSDictionary dictionaryWithObject:[NSNumber numberWithBool:YES]
forKey:CBConnectPeripheralOptionNotifyOnDisconnectionKey]];
[/objc][objc]
– (void)centralManager:(CBCentralManager *)central didConnectPeripheral:(CBPeripheral *)peripheral{
}
[/objc]
