每次我尝试跳过呼叫时,我的应用程序都会崩溃。没有调试器它工作正常。
此外,当我在模拟器中运行应用程序时,无论有没有调试器,它都可以正常工作。
最近我将我的 Mac OS X 10.8 升级到 10.9 (Mavericks)。升级前没有问题。
是什么导致了这个问题,我该如何解决?
下面是回溯。我的应用程序使用 ARC。我启用了僵尸并添加了异常断点,但没有检测到僵尸并且从未触发异常断点。

我有最新的 Xcode 版本 5.0.1 (5A2053)。
我从头开始创建了新应用程序并运行它没有问题。ViewController
然后我在's中放了一个断点viewDidLoad
并试图跨过去。在这里我遇到了另一个崩溃

Greg Clayton 在XCode 5 Crashes while running the app on device建议以下
Others have seen this issue.
A few things to try:
1 - Reboot your device and try again. The theory is an old developer disk image is already mounted and won't be unmounted until you reboot.
2 - Re-install the OS on the device
Hopefully #1 fixes your issue. Others have done #2 and had their issue fixed, but hopefully it doesn't require an OS re-install.
我都做了,但没有帮助。
我尝试使用另一台设备,结果有所不同。如果我在 iOS 6.1 上使用 iPod Touch,但在 iOS 7.0.2 上使用 iPad 时,例外情况仍然存在。
因此,看起来问题与设备上安装的 iOS 版本有关。我仍然不确定该怎么做才能修复它。

我的命令行工具版本与我的 Xcode 版本相匹配(实际上,我只有一个版本的命令行工具)。
这些问题可能与正在调试的代码无关。它与 Xcode 创建的新创建的单视图应用程序一起崩溃。跳过琐碎的代码时它会崩溃:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
我曾在 Apple Developer Forum 上提问并得到 Jason Molenda 的以下回复:
我们正在跟踪一个听起来像您在此处看到的错误。这是一个微妙的时序问题,需要稍慢的主机或稍慢的设备才能命中。在 iOS 7 中主要是 iPhone 4 和类似设备。在 iOS 6 中,iPhone 4 和 iPhone 3GS 设备最有可能遇到这种情况。...这个问题只会发生在 Xcode 5.0.1 上。
所以,这似乎是 Xcode 中的一个错误。
