此外,当我在模拟器中运行应用程序时,无论是否使用调试器都可以正常工作。
最近我将我的Mac OS X 10.8升级到10.9(Mavericks)。升级之前没有任何问题。
是什么导致了这个问题,我该如何解决?
以下是回溯信息。我的应用程序使用ARC。我已启用僵尸对象检测,并添加了异常断点,但未检测到僵尸对象,也未触发异常断点。

编辑:
我有最新的Xcode版本5.0.1(5A2053)。
我从头开始创建了一个新的应用程序,并且成功运行。然后我在ViewController
的viewDidLoad
中设置了一个断点,尝试跳过它。在这里我又遇到了另一个崩溃。

编辑2:
在XCode 5 Crashes while running the app on device中,Greg Clayton建议如下:
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.
我两个都试过了,但没有帮助。 我尝试使用另一台设备,它有所改善。 如果我使用iOS 6.1的iPod Touch,则仍然存在异常,但使用iOS 7.0.2的iPad正常工作。 因此,问题似乎与设备上安装的iOS版本有关。 我仍然不确定该怎么做才能解决它。 编辑3:我的命令行工具版本与我的Xcode版本匹配(实际上我只有一个版本的命令行工具)。 问题可能与正在调试的代码无关。 它会崩溃并在跨越微不足道的代码时崩溃,这是由Xcode创建的新创建的Single View Application引起的。
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
我在苹果开发者论坛上询问,并从Jason Molenda那里得到以下回复:
我们正在追踪一个听起来像你在这里看到的bug。这是一个微妙的时间问题,需要稍微慢一点的主机或稍微慢一点的设备才能击中它。主要是iPhone 4和类似设备在iOS 7下会出现这种情况。在iOS 6下,iPhone 4和iPhone 3GS设备最有可能遇到这个问题。...这个问题只会在Xcode 5.0.1中发生。
所以,看起来这是Xcode的一个bug。
