我正在使用 testflight 来测试我的应用程序，并且只有当应用程序是为临时构建并通过测试飞行分发时才会发生崩溃。相关崩溃报告详细信息如下：

NSInteger diff = sliceCount - [slicelayers count];

if(isOnEnd)

[self updateLabelForLayer:layer value:0];
[layer createArcAnimationForKey:@"startAngle"
fromValue:[NSNumber numberWithDouble:_startPieAngle]
toValue:[NSNumber numberWithDouble:_startPieAngle]
Delegate:self];
[layer createArcAnimationForKey:@"endAngle"
fromValue:[NSNumber numberWithDouble:_startPieAngle]
toValue:[NSNumber numberWithDouble:_startPieAngle]
Delegate:self];
}
[CATransaction commit];
return;
}
如果我可以在调试时重现它，我将能够追踪问题，但它似乎只在为临时构建时才会发生。谢谢！
编辑：
使用模拟器，我已将问题追踪到这一行的 EXC_BAD_ACCESS
[layersToRemove enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
我遇到了类似的问题并尝试更改项目构建设置，但它对我不起作用。最终通过更改发行版的编译器优化级别设置解决了我的问题：
在构建设置中，转到 LLVM 编译器 4.2 - 代码生成部分，查找优化级别选项并将发布设置从最快、最小 [-Os] 更改为无 [-O0]。
希望这可以帮助！
