问题连接的蓝牙设备，如在IOS 8连现有的代码没有找到蓝牙腕带和主要的东西它的工作在iOS 7..my代码很细的是建议我任何想法或蓝牙iOS 8的变化..

-(void)connecttodevice { 
     // Scan for all available CoreBluetooth LE devices 
     NSArray *services = @[[CBUUID UUIDWithString:info_UUID],[CBUUID UUIDWithString:info_UUID_service],[CBUUID UUIDWithString:BAND_SERVICE_INFO]]; 
     NSLog(@"device connting....."); 
     CBCentralManager *centralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil]; 
     [centralManager scanForPeripheralsWithServices:services options:nil]; 
     self.centralManager = centralManager; 
 } 

Answer 1:

你的问题是，你正在创建的CBCentralManager而不是等到中央管理器是在状态的动力作为指示后，立即调用scanForPeripheralsWithServices centralManagerDidUpdateState代表。

- (void)centralManagerDidUpdateState:(CBCentralManager *)central

     if (central.state == CBCentrallManagerStatePoweredOn {
        NSArray *services = @[[CBUUID UUIDWithString:info_UUID],[CBUUID UUIDWithString:info_UUID_service],[CBUUID UUIDWithString:BAND_SERVICE_INFO]]; 
        NSLog(@"device connting....."); 
        [central scanForPeripheralsWithServices:services options:nil];
     }
}

在iOS中7开始扫描，显示通电状态下前发出的控制台上的警告。 在iOS中8不开始扫描。
