これが私のコードです:
- (void)peripheralManager:(CBPeripheralManager *)peripheralManager central:(CBCentral *)central didSubscribeToCharacteristic:(CBCharacteristic *)characteristic
{
[self.centralManager retrievePeripherals:@[central.UUID]];
}
エラーが発生します:
Collection element of type 'CFUUIDRef' (aka 'const struct __CFUUID *') is not an Objective-C object
私は何をしますか?
