ios中关于检测应用安装和流量信息研究

关于检测应用安装和流量信息研究

1. 关于检测应用安装情况研究---

(1).利用URL scheme，看对于某一应用特有的url scheme，有没有响应。如果有响应，就说明安装了这个特定的app。

http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Introduction/Introduction.html

对于URL Scheme的使用请参看我之前的文章。

市场上有一部分应用检测安装是利用第三方ihasapp的接口获取的，目前ihasapp接口可以返回5000多个应用的URL Scheme。https://ihasapp.herokuapp.com/api/schemeApps.json 遍历列表，里面提供了每个应用的URL
Scheme，客户端利用application的openurl函数，一个一个在iphone上尝试打开这些app，不过这种实现方式会很快把你的iphone变成暖手宝.

(2)利用一些方法获得当前正在运行的进程信息，从进程信息中获得安装的app信息。

代码请参看http://forrst.com/posts/UIDevice_Category_For_Processes-h1H

缺点是打印输出的应用名称：让你找不到北，最熟悉的是找到tmall.

(3)破解手机的私有API可参看

http://stackoverflow.com/questions/3878197/is-it-possible-to-get-information-about-all-apps-installed-on-iphone/3878220#3878220

http://www.iphonedevsdk.com/forum/iphone-sdk-development/22289-possible-retrieve-these-information.html

关于越狱情况获取iphone用户安装的app列表：（这是从一篇讨论 360因为侵犯用户隐私被苹果下架 的文章中看来的）

已安装app列表 /private/var/mobile/Library/Caches/com.apple.mobile.installation.plist
用户相片 /var/mobile/Media/DCIM/100APPLE/
音乐目录 /var/mobile/Media/iTunes_Control/Music/

/private/ ，/var/都是合法app不能访问的目录，但是你的iphone一旦越狱，app就可以为所欲为。



2.关于流量检测研究-----

(1) 通过读取系统网络接口信息，可以获取当前iphone设备的流量相关信息， 但统计的是上次开机至今的流量信息。代码如下：

-(void)checkNetworkflow {

struct ifaddrs *ifa_list = 0, *ifa;

if (getifaddrs(&ifa_list) == -1){

return;

}

uint32_t iBytes = 0;

uint32_t oBytes = 0;

uint32_t allFlow = 0;

uint32_t wifiIBytes = 0;

uint32_t wifiOBytes = 0;

uint32_t wifiFlow = 0;

uint32_t wwanIBytes = 0;

uint32_t wwanOBytes = 0;

uint32_t wwanFlow = 0;

struct timeval time ;

for (ifa = ifa_list; ifa; ifa = ifa->ifa_next){

if (AF_LINK != ifa->ifa_addr->sa_family)

continue;

if (!(ifa->ifa_flags & IFF_UP) && !(ifa->ifa_flags & IFF_RUNNING))

continue;

if (ifa->ifa_data == 0)

continue;

// Not a loopback device.

// network flow

if (strncmp(ifa->ifa_name, "lo", 2)){

struct if_data *if_data = (struct if_data *)ifa->ifa_data;

iBytes += if_data->ifi_ibytes;

oBytes += if_data->ifi_obytes;

allFlow = iBytes + oBytes;

time = if_data->ifi_lastchange;

// NSLog(@"1111===%s :iBytes is %d, oBytes is %d", ifa->ifa_name, iBytes, oBytes);

}

//<span style="font-family: Tahoma, Helvetica, Arial, 宋体, sans-serif; ">WIFI流量统计功能</span>

if (!strcmp(ifa->ifa_name, "en0")){

struct if_data *if_data = (struct if_data *)ifa->ifa_data;

wifiIBytes += if_data->ifi_ibytes;

wifiOBytes += if_data->ifi_obytes;

wifiFlow = wifiIBytes + wifiOBytes;

}

//<span style="font-family: Tahoma, Helvetica, Arial, 宋体, sans-serif; ">3G和GPRS流量统计</span>

if (!strcmp(ifa->ifa_name, "pdp_ip0")){

struct if_data *if_data = (struct if_data *)ifa->ifa_data;

wwanIBytes += if_data->ifi_ibytes;

wwanOBytes += if_data->ifi_obytes;

wwanFlow = wwanIBytes + wwanOBytes;

//NSLog(@"111122===%s :iBytes is %d, oBytes is %d", ifa->ifa_name, iBytes, oBytes);

}

}

freeifaddrs(ifa_list);

// NSString *changeTime=[NSString stringWithFormat:@"%s",ctime(&time)];

// NSLog(@"changeTime==%@",changeTime);

NSString *receivedBytes= [self bytesToAvaiUnit:iBytes];

NSLog(@"receivedBytes==%@",receivedBytes);

NSString *sentBytes = [self bytesToAvaiUnit:oBytes];

//self.textView.text = alltext;

int i = [selfgetGprs3GFlowIOBytes];

NSLog(@"3G 流量-----%d",i);

int j = [selfgetInterfaceBytes];

NSLog(@"wifi 流量-----%d",j);

}

-(NSString *)bytesToAvaiUnit:(int)bytes {

if(bytes < 1024) // B

{

return [NSString stringWithFormat:@"%dB", bytes];

}

else if(bytes >= 1024 && bytes < 1024 * 1024) //
KB

{

return [NSString stringWithFormat:@"%.1fKB",
(double)bytes / 1024];

} else if(bytes >= 1024 * 1024 && bytes < 1024 * 1024 * 1024) //

{

return [NSString stringWithFormat:@"%.2fMB",
(double)bytes / (1024 * 1024)];

} else // GB

{

return [NSString stringWithFormat:@"%.3fGB",
(double)bytes / (1024 * 1024 * 1024)];

}

}



//--- 3G/GPRS流量统计

-(int) getGprs3GFlowIOBytes

{

struct ifaddrs *ifa_list = 0, *ifa;

if (getifaddrs(&ifa_list) == -1)

{

return 0;

NSLog(@"%s :iBytes is %d, oBytes is %d",

ifa->ifa_name, iBytes, oBytes);

}

}

freeifaddrs(ifa_list);

return iBytes + oBytes;

}

//WIFI流量统计功能

- (long long int)getInterfaceBytes

{

continue;

/* Not a loopback device. */

if (strncmp(ifa->ifa_name, "lo", 2))

}

可以获取内容有：

WIFI接收数据流量，WIFI发送数据流量；

3G和GPRS接收数据流量，3G和GPRS发送数据流量；

通过查看其他流量软件具体到每日每月总流量，越狱情况下应该可以实现这每日每月总流量检测， 但我还未找到获取单个应用的流量信息私有API，大家有知道怎么获取的，也分享下，呵呵。
