我正在尝试subLayers在我的parentLayer. 这是我创建我的方式CALayer：

_imgZutendaal = [CALayer layer];
_imgZutendaal.contents = (id)[imZutendaal CGImage];
_imgZutendaal.frame = CGRectMake(0, 0, 656, 608);

这就是我将它添加到我的 parentLayer 的方式：

[self.layer addSublayer:_imgAchel];

但由于某种原因，它崩溃而没有任何错误消息。当我只添加例如 10 个子层时，一切正常。

有人可以帮助我吗？

您的应用程序内存不足。崩溃报告表明您的应用程序使用了 166401 页内存，即 650 MByte。因为这个原因，它被杀死了。

您的层很可能是内存问题的主要原因。单个图层的内存消耗将取决于其内容，即取决于您分配的图像。如果图像是 600 x 600 像素，那么它至少会消耗 1 MByte (600 x 600 x 3)。

使用 Instruments 来分析您的应用程序的内存使用情况。找出内存使用量增加的原因和位置。在开始添加层之前，内存使用量可能已经非常高。或者您多次添加相同的图层。
