AppSync会导致iCloud和应用内购买出现问题,因此我想检测设备上是否存在处理iCloud和IAP奇怪行为的问题。有没有办法知道这个?
没关系设备是否越狱,但AppSync阻止我的应用程序正常工作,而且它显然是“一线黑客”。
答案 0 :(得分:1)
我搜索并发现了AppSync的痕迹,这里是代码,以确定它是否存在于设备上。是的,它比需要的时间长一点,但我想确定。当然在发布代码中你应该以某种方式混淆字符串,但就是这样:
bool isAppSyncExist()
{
BOOL isbash = NO;
BOOL isappsync = NO;
FILE *f = fopen("/bin/bash", "r");
if (f != NULL)
{
//Device is jailbroken
isbash = YES;
fclose(f);
}
if (isbash)
{
f = fopen("/Library/MobileSubstrate/DynamicLibraries/AppSync.plist", "r");
if (f != NULL)
{
isappsync = YES;
fclose(f);
}
if (isappsync == NO)
{
NSError *err;
NSArray *files = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:@"/private/var/lib/dpkg/info" error:&err];
for (int i = 0; i < files.count; i++)
{
NSString *fname = [files objectAtIndex:i];
if ([fname rangeOfString:@"appsync" options:NSCaseInsensitiveSearch].location != NSNotFound)
{
isappsync = YES;
break;
}
}
}
if (isappsync == NO)
{
NSError *err;
NSArray *files = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:@"/var/lib/dpkg/info" error:&err];
for (int i = 0; i < files.count; i++)
{
NSString *fname = [files objectAtIndex:i];
if ([fname rangeOfString:@"appsync" options:NSCaseInsensitiveSearch].location != NSNotFound)
{
isappsync = YES;
break;
}
}
}
}
return isappsync == YES;
}
