输出log日志的数据格式

{
    "cpu": "0.4",
    "fps": "60 FPS",
    "version": "11.2",
    "appname": "xxxxxx",
    "battery": "-100.0",
    "appversion": "5.0.4",
    "time": "2018-09-07 11:45:24",
    "memory": "141.9",
    "devicesName": "xxxxxx",
    "vcClass": "DDAlreadPaidTabListVC",
    "idf": "8863F83E-70CB-43D5-B6C7-EAB85F3A2AAD"
}

开一个子线程定时采集数据

/*
 * 性能采集子线程
 */

- (void) performancethread {
    NSThread *thread = [[NSThread alloc] initWithBlock:^{
        NSLog(@"performance   ======get performance======");

        [self get_fps];

        while (true) {
            DDPerformanceModel *model = [DDPerformanceModel new];
            model.time=[self get_time];
            model.appname=[self get_appname];
            model.appversion=[self get_appversion];
            model.idf =[self get_idf];
            model.devicesName =[self get_devicesName];
            model.version = [self get_systemVersion ];
            model.vcClass = NSStringFromClass([self get_vc].class);
            model.memory = [self get_memory];
            model.battery = [self get_battery];
            model.cpu = [self get_cpu];
            model.fps = self.percount;

            NSString *json = [model modelToJSONString];

//            printf(" getperformance    %s\r\n", [json UTF8String]);
            NSLog(@"getperformance model  %@", json);
            sleep(5);
        }
    }];
    [thread start];

    NSLog(@"performance   ======continue mainblock======");
}

AppDelegate.m文件中didFinishLaunchingWithOptions方法中用户各种初始化操作,可以在第一行初始化性能采集,
这样app启动以后就可以定时采集数据

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    [[getperformance new] performancethread];//获取性能数据

    }

模拟器可以使用xcrun simctl命令获取当前设备运行日志,
真机用libimobiledevice获取日志

xcrun simctl spawn booted log stream --level=debug | grep getperformance

输出log日志的数据格式,这块做了json美化,每歌几秒在控制台就打印一次

{
    "cpu": "0.4",
    "fps": "60 FPS",
    "version": "11.2",
    "appname": "xxxxxx",
    "battery": "-100.0",
    "appversion": "5.0.4",
    "time": "2018-09-07 11:45:24",
    "memory": "141.9",
    "devicesName": "xxxxxx",
    "vcClass": "DDAlreadPaidTabListVC",
    "idf": "8863F83E-70CB-43D5-B6C7-EAB85F3A2AAD"
}

如果获取多次数据可以使用shell脚本把命令放到后台,定时写入到logpath中
nohup xcrun simctl spawn booted log stream --level=debug >${logpath} &

scriptrootpath=${2}
AddFiles=${2}"/GetPerformance/performancefiles"
localDDPerformanceModelh=${scriptrootpath}"/GetPerformance/performancefiles/DDPerformanceModel.h"
localDDPerformanceModelm=${scriptrootpath}"/GetPerformance/performancefiles/DDPerformanceModel.m"
localgetperformanceh=${scriptrootpath}"/GetPerformance/performancefiles/getperformance.h"
localgetperformancem=${scriptrootpath}"/GetPerformance/performancefiles/getperformance.m"

addfiles(){

    echo "删除${projectaddpath}中的原性能采集文件"

    rm -rf ${DDPerformanceModelh}
    rm -rf ${DDPerformanceModelm}
    rm -rf ${getperformanceh}
    rm -rf ${getperformancem}

    echo "复制文件到${projectaddpath}路径"

    cp  ${localDDPerformanceModelh} ${projectaddpath}
    cp  ${localDDPerformanceModelm} ${projectaddpath}
    cp  ${localgetperformanceh} ${projectaddpath}
    cp  ${localgetperformancem} ${projectaddpath}

}
