使用GameKit实现蓝牙功能

首先需要导入GameKit框架

实现代码如下

需要建立GKPeerPickerControllerDelegate

@interface ViewController ()<GKPeerPickerControllerDelegate,UINavigationControllerDelegate,UIImagePickerControllerDelegate>

 @property (nonatomic, strong) GKSession *session;

 

 // 创建蓝牙选择器
    GKPeerPickerController *picker = [[GKPeerPickerController alloc]init];
    picker.delegate = self;
    // 显示
    [picker show];

 

/*
 * 连接蓝牙的方式    附近    在线
 */
- (void)peerPickerController:(GKPeerPickerController *)picker didSelectConnectionType:(GKPeerPickerConnectionType)type {
    NSLog(@"%s  %d  type =%lu  picker %@",__func__,__LINE__,(unsigned long)type,picker);
}

// 连接会话的方式   附近  在线
- (GKSession *)peerPickerController:(GKPeerPickerController *)picker sessionForConnectionType:(GKPeerPickerConnectionType)type {
    
    return nil;
}

/* 连接成功
 *  peerID  连接成功的设备id
