iOS開發(fā)丨藍(lán)牙4.0復(fù)制粘貼就能使用的CoreBluetooth藍(lán)牙框架

作為多年的iOS藍(lán)牙開發(fā)者，下面共享一下我自己搭建和使用的藍(lán)牙框架飒箭。首先創(chuàng)建一個(gè)類BluetoothManager，用來管理CBCentralManager和CBPeripheral蜒灰，以及一些掃描連接的公共方法弦蹂，其中數(shù)據(jù)和狀態(tài)回調(diào)使用通知的形式進(jìn)行處理，這樣在整個(gè)項(xiàng)目中强窖，只需要保存一份BluetoothManager就可以了凸椿，而不是在每個(gè)需要藍(lán)牙的頁面都生成CBCentralManager。

BluetoothManager.h文件實(shí)現(xiàn)：

使用方法：

1燥撞、在AppDelegate的didFinishLaunchingWithOptions中調(diào)用[BluetoothManager sharedModel]進(jìn)行初始化座柱，如果藍(lán)牙未授權(quán)，則此時(shí)系統(tǒng)會(huì)自動(dòng)調(diào)用授權(quán)彈窗物舒。

2色洞、在viewDidLoad中添加藍(lán)牙事件通知監(jiān)聽，在viewDidDisappear中移除通知監(jiān)聽冠胯。

3火诸、實(shí)現(xiàn)通知監(jiān)聽的回調(diào)方法，來處理藍(lán)牙設(shè)備的不同情況荠察。

/////////////////////////////////////////////////////////////////////////////////////////////////////////
#pragma mark BluetoothNotification
/////////////////////////////////////////////////////////////////////////////////////////////////////////

- (void)BLENotificationBLECenterChangeState:(NSNotification *)notif {
    CBCentralManager *central = notif.object;
    if (central.state == CBCentralManagerStatePoweredOn) {
        // 藍(lán)牙打開
    }
    else {
        // 藍(lán)牙關(guān)閉
    }
}

- (void)BLENotificationPeripheralDidConnected:(NSNotification *)notif {
    // 設(shè)備連接成功
}

- (void)BLENotificationPeripheralDisconnected:(NSNotification *)notif {
    // 設(shè)備斷開連接
}

- (void)BLENotificationPeripheralConnectFailed:(NSNotification *)notif {
    // 設(shè)備連接失敗
}

- (void)BLENotificationPeripheralSessionError:(NSNotification *)notif {
    // 藍(lán)牙異常狀態(tài)處理
}

4置蜀、調(diào)用scanWithPrefixNames進(jìn)行掃描設(shè)備，如傳入@[@"FOT"]表示只搜索設(shè)備名為FOT開頭的藍(lán)牙設(shè)備悉盆，如果不希望過濾設(shè)備名盯荤，可傳入@[@""]；timeout可以指定掃描時(shí)間焕盟，一般為10秒秋秤，10秒過后自動(dòng)停止掃描，也可以傳0脚翘，這時(shí)候會(huì)在后臺(tái)一直掃描灼卢，除非調(diào)用stopScan方法停止掃描。scanBlock為符合條件的設(shè)備回調(diào)来农，你可以在這里對設(shè)備進(jìn)行判斷和連接操作鞋真。timeoutBlock為超時(shí)后的回調(diào)，如果不使用可傳nil沃于。

// 掃描設(shè)備名為ABC123的藍(lán)牙設(shè)備涩咖，如果掃描到則進(jìn)行連接
[[BluetoothManager sharedModel] scanWithPrefixNames:@[@"ABC123"] timeout:0.0 scanBlock:^(CBPeripheral *peripheral, NSDictionary *advertisementData, NSNumber *RSSI) {
    [BluetoothManager sharedModel].willConnectPeripheral = peripheral;  // 必須保存此變量，才可正常連接
    [[BluetoothManager sharedModel] connect:[BluetoothManager sharedModel].willConnectPeripheral timeout:10.0];  //連接指定設(shè)備
    [[BluetoothManager sharedModel] stopScan];  // 停止掃描
} timeoutBlock:nil];

5揽涮、使用writeValueToPeripheral來將值寫入設(shè)備中抠藕。

[[BluetoothManager sharedModel] writeValueToPeripheral:data block:^(BOOL success) {
    if (success) {
        // 數(shù)據(jù)寫入成功
    }
    else {
        // 數(shù)據(jù)寫入失敗
    }
}];
