How to monitoring App running in the foreground in

Everyone Great God！I really need help~

Before iOS8，I use the PrivateFrameworks SpringBoardServices monitoring the App running in foreground is fine. Like the following code：

#define SPRINGBOARDPATH "/System/Library/PrivateFrameworks/SpringBoardServices.framework/SpringBoardServices"
....
+(void) monitoringFrontApp {
    mach_port_t *port;
    void *uikit = dlopen(SPRINGBOARDPATH, RTLD_LAZY);
    int (*SBSSpringBoardServerPort)() =
    dlsym(uikit, "SBSSpringBoardServerPort");
    port =  (mach_port_t *)SBSSpringBoardServerPort();

    //dynamic link sys mothed
    void* (*SBFrontmostApplicationDisplayIdentifier)(mach_port_t* port,char * result) =
    dlsym(uikit, "SBFrontmostApplicationDisplayIdentifier");
    //call mothed
    char frontmostAppS[256];
    memset(frontmostAppS,sizeof(frontmostAppS),0);
    SBFrontmostApplicationDisplayIdentifier(port,frontmostAppS);
    NSString * app_id = [NSString stringWithUTF8String:frontmostAppS];

    NSLog(@"front display app Identifier----%@", app_id);

    //dynamic link sys mothed
    CFStringRef (*SBSCopyLocalizedApplicationNameForDisplayIdentifier)(CFStringRef displayIdentifier) =
    dlsym(uikit, "SBSCopyLocalizedApplicationNameForDisplayIdentifier");
    //call mothed
    CFStringRef locName = SBSCopyLocalizedApplicationNameForDisplayIdentifier((__bridge  CFStringRef)app_id);
    NSString *app_name = [NSString stringWithFormat:@"%@",locName];
    if (locName != NULL)CFRelease(locName);

     NSLog(@"front display app name----%@", app_name);
}

But... Recently released iOS8,Everything is change. I cann't get by call 'SBFrontmostApplicationDisplayIdentifier' to front display app Identifier,and 'SBSCopyLocalizedApplicationNameForDisplayIdentifier' is invaild.

so, I searched on google for a long time not have result, everyone reply would be appreciated!!!
