iOS 8和ble CBCentralManager無法正常工作

Question

我有一個iOS應用程序，它使用ble連接到設備。 iOS 7正在運行。 升級到iOS 8后，CBCentralManager找不到任何外圍設備。

    case CBCentralManagerStatePoweredOn:
    {

        NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:FALSE], CBCentralManagerScanOptionAllowDuplicatesKey, nil];
        //NSArray *services = [NSMutableArray new];
        NSArray *services = @[[CBUUID UUIDWithString:@"0000FBB0-494C-4F47-4943-544543480000"], [CBUUID UUIDWithString:@"180A"]];
        [centralManager scanForPeripheralsWithServices:services options:options];

        break;
    }

Answer 1

嘗試移動以下代碼：

 NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:FALSE], CBCentralManagerScanOptionAllowDuplicatesKey, nil];
    //NSArray *services = [NSMutableArray new];
    NSArray *services = @[[CBUUID UUIDWithString:@"0000FBB0-494C-4F47-4943-544543480000"], [CBUUID UUIDWithString:@"180A"]];
    [centralManager scanForPeripheralsWithServices:services options:options];

進入Iba操作，然后在CBCentralManagerStatePoweredOn上調用該操作
