Ios 如何将不同类的精灵添加到场景中？

我创建了一个名为“level1Layout.m”和“level1Layout.h”的新类。这些是分类代码

level1Layout.m

level1Layout.h

请有人帮忙。

当我将“testMethod”更改为实例时，当它崩溃时，我会在控制台中得到它

我找到了导致它的原因，就是这一部分

[NSTimer scheduledTimerWithTimeInterval:2
                                         target:self
                                       selector:@selector(runLevel1Layout)
                                       userInfo:nil
                                        repeats:NO];

---

您的崩溃日志中描述的问题起源于：

+(void) testMethod{
    // ...
    [NSTimer scheduledTimerWithTimeInterval:0.1
                                     target:self
                                   selector:@selector(addSprite)
                                   userInfo:nil
                                    repeats:NO];
}

注意

testMethod

之前的

+

：这是一个类方法。因此，您正在安排计时器调用

+[level1Layout addSprite]

，但是

addSprite

是一个实例方法（用

-

声明）：

-[level1Layout addSprite]

）

因此，您需要将

testMethod

声明为实例方法，或者更改目标

self

，以指向

level1Layout

的特定实例

阅读您的代码的人的勇气哈哈，很抱歉发布了这么多lol@BeguerajYou不应该在Sprite Kit中使用NSTimer：谢谢，尽管Sprite从未出现，但计时器仍然更容易键入@事实上，你告诉我要用的新定时器从未被调用过，也从未做过它应该做的事。。代码跳过了它或者@learncos2dok，所以我把它改成了一个实例，然后它又崩溃了，我编辑了我的帖子并加入了一些东西。你看到新的错误了吗？我打赌你一定能弄明白。这与第一个错误非常相似。我确实犯了，我想我已经发现了。。我只是将“runAddLevel1Layout”更改为实例，而不是类方法。但是精灵从来没有出现过。。但是没有错误
