前面几章，代码经过重构，可能有点乱。这里给个最终版本，以供参考。
1、应用基类：
IScean.h
enum SceanResult{
SceanResult_EXIT = 1,
SceanResult_Done = 2
};
class IScean {
public:
IScean();
virtual ~IScean();
// 纯虚函数
virtual SceanResult tick(u32 ticks) = 0;
virtual int scean_init(cJSON* param) {return 0;};
virtual int scean_resume(void){return 0;};
virtual int scean_pause(void){return 0;};
protected:
map_t iconMap = NULL;
unsigned char* getImageResource(char* fn);
};IScean.cpp
int iterate(any_t item, any_t data){
psram_heap_free((unsigned char *)data);
return MAP_OK;
}
IScean::IScean(){
iconMap = hashmap_new();
}
IScean::~IScean(){
any_t val;
hashmap_iterate(iconMap, iterate, val);
hashmap_free(iconMap);
}
unsigned char* IScean::getImageResource(char* fn){
int error;
unsigned int w,h;
unsigned char *val;
error= hashmap_get(iconMap, fn, (void**)(&val));
if(error == MAP_MISSING){
lodepng_decode32_file(&val, &w, &h, fn);
hashmap_put(iconMap, fn, val);
}
return val;
