创建WCCrashBlockMonitorPlugin插件的代码

        let config = WCCrashBlockMonitorConfig()
        config.enableCrash = true
        config.enableBlockMonitor = true
        config.reportStrategy = .all

        let blockMonitorConfig = WCBlockMonitorConfiguration.defaultConfig() as! WCBlockMonitorConfiguration
        blockMonitorConfig.bMainThreadHandle = true
        blockMonitorConfig.bGetPowerConsumeStack = true
        config.blockMonitorConfiguration = blockMonitorConfig

        let plugin = WCCrashBlockMonitorPlugin()
        plugin.pluginConfig = config
