Instruments报告最后一行有一个由NSPlaceHolderString引起的16字节泄漏

我想我遗漏了一些明显的东西,但我不太明白是什么
谢谢你的帮助
更新:我已经将有问题的代码块复制到ApplicationIDFinishLaunching的第一部分,但它仍然泄漏。我的模型有问题吗
您是否发布可用性系列?除此之外,我什么也没看到 您是否发布可用性系列?除此之外,我什么也没看到 > P> NSPlaceHolder是由基础库使用的“单点”,在诸如:等结构中推迟NSRSITE内存的分配。

如果你只漏过一次,那就不是真的漏了
- 我说“singleton”和“one”,但可以有多个NSPlaceHolderString—如果使用allocWithZone,则每个NSZone一个
