请问在ios9系统中如何获取进程信息

我现有的代码是这样的，但是在ios9下是获取不到进程信息的，请问我如何获取进程信息

• (NSArray *)runningProcesses1 {
  int mib[4] = {CTL_KERN, KERN_PROC, KERN_PROC_ALL, 0};
  size_t miblen = 4;

  size_t size;
  int st = sysctl(mib, miblen, NULL, &size, NULL, 0);

  struct kinfo_proc * process = NULL;
  struct kinfo_proc * newprocess = NULL;

  do {
  size += size / 10;
  newprocess = realloc(process, size);
  if (!newprocess){
  if (process){
  free(process);
  }
  return nil;
  }
  process = newprocess;
  st = sysctl(mib, miblen, process, &size, NULL, 0);
  } while (st == -1 && errno == ENOMEM);

  if (st == 0){
  if (size % sizeof(struct kinfo_proc) == 0){
  int nprocess = size / sizeof(struct kinfo_proc);
  if (nprocess){
  NSMutableArray * array = [[NSMutableArray alloc] init];
  for (int i = nprocess - 1; i >= 0; i--){
  NSString * processID = [[NSString alloc] initWithFormat:@"%d", process[i].kp_proc.p_pid];
  NSString * processName = [[NSString alloc] initWithFormat:@"%s", process[i].kp_proc.p_comm];
  double t = [[NSDate date] timeIntervalSince1970] - process[i].kp_proc.p_un.__p_starttime.tv_sec;
  NSString * proc_useTiem = [[NSString alloc] initWithFormat:@"%f",t];
  
  NSDictionary * dict = [[NSDictionary alloc] initWithObjects:[NSArray arrayWithObjects:processID, processName,proc_useTiem, nil]
  forKeys:[NSArray arrayWithObjects:@"ProcessID", @"ProcessName", @"time",nil]];
  [array addObject:dict];

          }
          free(process);                                                                    return array;
      }
  }
  

  }
  return nil;
  }

你要把这段放到target只是ios9的看看，是不是部分方法不再支持了
