我有一个自定义键盘，其中图像按类别划分。现在我每个类别都有 12 张图片。如果我有一个包含 20 个图像的类别，例如键盘崩溃。我已经寻找解决方案很长时间了，但没有运气。 当我调试 iPhone 中的键盘时，我收到 SIGQUIT 信号:

有什么想法吗？ 更新 我创建了一个期望断点，并在加载 nib 文件的位置得到了断点。
- (void)arrangeXib{
self.keyboard = [[[NSBundle mainBundle]loadNibNamed:@"iPhone" owner:nil options:nil] objectAtIndex:0];
self.inputView = (UIInputView *)self.keyboard;

更新2: 我很确定这与内存问题有关...如果我在单元格中仅显示彩色背景，它就可以正常工作。现在，如果我显示图像，如果它们少于 10-15 则没有问题，但如果我有更多图像，它将因不同的错误而崩溃，如上面的错误或:
libz.1.dylib`inflate:
libsystem_kernel.dylib`_kernelrpc_mach_vm_deallocate_trap:
起初我有一个 ScrollView ，我认为问题是它直接加载了所有图像，所以我尝试使用 collectionView 但结果相同。我尝试以 3 种不同的方式加载图像，但结果相同:
UIImage imageWithContentsOfFile:
UIImage imageWithData:
UIImage imageNamed:
最佳答案
现在可以使用了。正如我所料，问题与内存有关。对于第 3 方键盘，我读到苹果将内存限制为 30Mb。
Memory limits for running app extensions are significantly lower than the memory limits imposed on a foreground app. On both platforms, the system may aggressively terminate extensions because users want to return to their main goal in the host app. Some extensions may have lower memory limits than others: For example, widgets must be especially efficient because users are likely to have several widgets open at the same time.
我有每个大约 60Kb 的 png 图像，但它有一个 24 位彩色位图，当我加载它们时，每个图像在内存中的大小约为 5-6Mb。我的解决方案是使用 jpeg 图像，我将无法使用透明背景，但至少我会有一个工作应用程序。
关于objective-c - 自定义键盘崩溃共享库事件(内存泄漏？)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45468154/
