我有一个struct Position,像这样:

typedef struct Position { int x, y; } Position;

我怎么能在NSObject中传递它performSelector:withObject:afterDelay:？像这样:

Position pos;
pos.x = pos.y = 1;
[self performSelector:@selector(foo:)
           withObject:pos               // ERROR
           afterDelay:5.0f];

编辑:更改代码以修复拼写错误
