Question

当我使用模拟器时 - ＆gt;发布配置代码运行正常。但如果我使用模拟器 - ＆gt;调试配置给我以下错误

Undefined symbols:
  "_AGTileInfoEqualToAGTile", referenced from:
      -[TiledScrollView loadTileAtPoint:] in TiledScrollView.o
  "_AGTileInfoMake", referenced from:
      -[TiledScrollView loadTilesIfNeeded] in TiledScrollView.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

以下是代码

typedef struct 
{
    NSString *dataSet;
    NSInteger level;
    NSInteger x;
    NSInteger y;


}AGTileInfo;


/* Make a AGTileInfo  */
inline AGTileInfo AGTileInfoMake(NSString *dataSet, NSInteger level, NSInteger x, NSInteger y);

inline AGTileInfo
AGTileInfoMake(NSString *dataSet, NSInteger level, NSInteger x, NSInteger y)
{
    AGTileInfo tInfo;   tInfo.dataSet = dataSet;    tInfo.level = level;    tInfo.x = x;    tInfo.y = y;    return tInfo;
}



inline bool AGTileInfoEqualToAGTile(AGTileInfo info1, AGTileInfo info2);

inline bool
AGTileInfoEqualToAGTile(AGTileInfo info1, AGTileInfo info2)
{
    return [info1.dataSet isEqualToString:info2.dataSet] && (info1.level==info2.level) && (info1.x == info2.x) && (info1.y == info2.y) ;
}

提前致谢。

你是否尝试过没有“内联”条款进行编译？

看看这个： Objective C: Inline function - symbol not found

感谢xj1200。他的链接非常有帮助。我所做的只是在内联之前添加“静态”修饰符。这是新代码，它工作正常。

static inline AGTileInfo AGTileInfoMake(NSString *dataSet, NSInteger level, NSInteger x, NSInteger y);

static inline AGTileInfo
AGTileInfoMake(NSString *dataSet, NSInteger level, NSInteger x, NSInteger y)
{
    AGTileInfo tInfo;   tInfo.dataSet = dataSet;    tInfo.level = level;    tInfo.x = x;    tInfo.y = y;    return tInfo;
}


static inline bool AGTileInfoEqualToAGTile(AGTileInfo info1, AGTileInfo info2);

static inline bool
AGTileInfoEqualToAGTile(AGTileInfo info1, AGTileInfo info2)
{
    return [info1.dataSet isEqualToString:info2.dataSet] && (info1.level==info2.level) && (info1.x == info2.x) && (info1.y == info2.y) ;
}

iPhone： - 使用内联函数： - 使用调试配置时显示错误
