如何访问精灵数组中的第一个精灵并将其位置更改为此？

        sprite.position = CGPointMake(arc4random_uniform(self.frame.size.width), arc4random_uniform(self.frame.size.height));

@property (nonatomic, strong) SKSpriteNode *aSprite;
@property (nonatomic) NSMutableArray *sprites;

要访问精灵数组中的第一个对象，您可以这样做：

SKSpriteNode *object = [myArray firstObject];
object.position = CGPointMake(arc4random_uniform(self.frame.size.width), arc4random_uniform(self.frame.size.height));

要访问数组中的所有对象，请执行以下操作：

for(SKSpriteNode *object in myArray) {
    object.position = CGPointMake(arc4random_uniform(self.frame.size.width), arc4random_uniform(self.frame.size.height));
}
