我正在尝试创建一个应用程序，其中两个不同的设备可以使用相同的UIControlView相互通信，使用iBeacon来回发送通知，并使用bluetoothle来回发送数据 .
我首先派出一个邻近的iBeacon来询问该地区的人是否想要玩游戏 .
如果获得通知的某人点击“确定”按钮，则他们通告蓝牙特征，其 Value 是原始人正在收听的唯一用户ID和服务，然后是提示他们想要播放的原始人的iBeacon通知 .
完成此操作后，应用程序停止外围设备广告，并根据自己的用户ID和部分UUID启动centralManager扫描不同的服务UUID .
我使用位置管理器来获取邀请通知 . 然后，当点击“确定”按钮时，我使用
-(void) alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex{
if (AlertView) {
NSLog(@"idenify:%@",identifierString);
if ([identifierString isEqualToString:@"com.checkers.bluetooth"]) {
if (buttonIndex == 0) {
[UIView animateWithDuration:2 delay:0 options:UIViewAnimationOptionCurveEaseIn animations:^{
//here I clear the CentralManager so a new service can be looked for
centralManager = nil;
//here the peripheralManager sends the unique code
[self.peripheralManager startAdvertising:@{ CBAdvertisementDataServiceUUIDsKey : @[[CBUUID UUIDWithString:sendUUID]] }]; recieve.frame = CGRectMake(147,55,20,20); } completion:^ (BOOL completed) {
//here the peripheralManager sends the proximity notification
NSUUID * uid = [[NSUUID alloc] initWithUUIDString:@"55DCE9F4-7942-4B9D-B914-50426D6CC976"];
self.beaconRegion = [[CLBeaconRegion alloc] initWithProximityUUID:uid identifier:@"com.checkersok.bluetooth"];
[self configureTransmitter];
[self.peripheralManager startAdvertising:self.peripheralData];inviteCheckers.hidden = YES; [self.recieve setBackgroundImage:[UIImage imageNamed:@"accept.png"] forState:UIControlStateNormal];[UIView animateWithDuration:1 delay:2 options:UIViewAnimationOptionCurveEaseIn animations:^{ movementImage.frame = CGRectMake(300,292,17,17);
} completion:^ (BOOL completed) {
//here the peripheral manager is stopped
[self.peripheralManager stopAdvertising];
NSString *startString2 = userId.text;
NSString *endString2 = [startString2 stringByAppendingString:@"-2C29-40E0-8E1E-1D7A9E5D0964"];
recieverUUID =endString2;
self.userUUIDString = @"YES";
NSLog(@"userUUIDString2;%@",userUUIDString);
NSLog(@"recieverUUID7;%@",recieverUUID);
//here the centralManager is allocated again and starts scanning for the new service UUID
centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil];
[self.centralManager scanForPeripheralsWithServices:@[[CBUUID UUIDWithString:recieverUUID]] options:@{ CBCentralManagerScanOptionAllowDuplicatesKey : @YES }];} ];} ];
NSLog(@"userUUIDString:%@",userUUIDString);
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
}
当发件人收到有人愿意播放的通知时，我将peripheralManager设置为nil，这样我就可以将其设置为其他内容 .
当原始人（发送者）轻击“确定”按钮时，我重新分配外围管理器并基于第二人用户ID和UUID的同一端开始广播服务UUID . 这是sendUUID .
else if ([identifierString isEqualToString:@"com.checkersok.bluetooth"]) {
if (buttonIndex == 0) {
[timer4 invalidate];
self.peripheralManager = [[CBPeripheralManager alloc] initWithDelegate:self queue:nil];
[self.peripheralManager startAdvertising:@{ CBAdvertisementDataServiceUUIDsKey : @[[CBUUID UUIDWithString:sendUUID]] }];
movementImage.frame = CGRectMake(283,292,17,17); } completion:^ (BOOL completed) {
} ];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
self.userUUIDString = userField.text;
}
这就是问题所在 . 我知道正在调用peripheralManager并且正在发送数据，并且CentralManager正在通过日志进行连接 .
这是发件人日志 .

如您所见，peripheralManager正在做广告，而centralManager正在扫描 . 中央找到外围设备并连接但停止 . 通常外围设备继续做广告，并且中央必须在获取数据之前连接和断开连接一段时间 . 这是我不知道如何开始工作，因为我使用相同的代码来发送和接收这些数据，而我使用从第二个人发送到第一个人的数据 .
我已经尝试了几种不同的方法来实现这一点，但不能 . 任何人都可以告诉我如何让这个工作？
