在IOS 7中不推荐使用retrievePeripherals如何用retrievePeripheralsWithIdentifiers替换它

Question

我使用的"[self.manager retrievePeripherals:[NSArray arrayWithObject:(id)aPeripheral.UUID]];”工作正常，但在IOS7中已弃用。我发现我必须使用“retrievePeripheralsWithIdentifiers”。但我无法弄清楚哪个是新函数的正确语法。任何人都可以请翻译

"[self.manager retrievePeripherals:[NSArray arrayWithObject:(id)aPeripheral.UUID]];”

到新函数“retrievePeripheralsWithIdentifiers”。

// Invoked when the central discovers heart rate peripheral while scanning.
- (void) centralManager:(CBCentralManager *)central
  didDiscoverPeripheral:(CBPeripheral *)aPeripheral
  advertisementData:(NSDictionary *)advertisementData
               RSSI:(NSNumber *)RSSI
{
    NSMutableArray *peripherals = [self mutableArrayValueForKey:@"heartRateMonitors"];
    if(![self.heartRateMonitors containsObject:aPeripheral])
    [peripherals addObject:aPeripheral];

    // Retrieve already known devices
[self.manager retrievePeripherals:[NSArray arrayWithObject:(id)aPeripheral.UUID]];

}

最后我可以解决它，希望它有所帮助。

// Invoked when the central discovers heart rate peripheral while scanning.
- (void) centralManager:(CBCentralManager *)central
  didDiscoverPeripheral:(CBPeripheral *)aPeripheral
  advertisementData:(NSDictionary *)advertisementData
               RSSI:(NSNumber *)RSSI
{
[self.manager retrievePeripheralsWithIdentifiers:@[[CBUUID UUIDWithString:@"180D"]]];

NSLog(@"centralManager didDiscoverPeripheral -> Discovered: %@", aPeripheral.name);

if (aPeripheral) {
    [self stopScan];
    _peripheral = aPeripheral;
    [_manager connectPeripheral:self.peripheral
                        options:[NSDictionary dictionaryWithObject:
                                 [NSNumber numberWithBool:YES]
                                                            forKey:
                                 CBConnectPeripheralOptionNotifyOnDisconnectionKey]];
}


}
