在用反射调用sdk动态库，发现必须要加载一次，所以备注dlopen提前加载动态库

   NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
   NSString* dlPath = [NSString stringWithFormat: @"%@/Frameworks/###.framework/###", resourcePath];
  const char* cdlpath = [dlPath UTF8String];
  void* hModule = dlopen(cdlpath, RTLD_LAZY); 
  dlclose(hModule);
