在分析设备上运行的应用程序并使用 xcode 分析器检测泄漏时，程序收到信号：SIGKILL 是什么意思？
My app broke on a line calling drawInRect on a UIImage instance
我的应用程序在 UIImage 实例上调用 drawInRect 的行中断
top of call stack is CGGStateCreateCopy
调用堆栈的顶部是 CGGStateCreateCopy

SIGKILLis a signal that is common across POSIX systems, such as in your iphone OS, which it issued the signal to your application. SIGKILL cannot be caught programmatically. Usually to kill a process involves entering this on the command line, remember you can do this to the processes that you own since you logged into the shell:
SIGKILL是 POSIX 系统中常见的信号，例如在您的 iphone 操作系统中，它向您的应用程序发出信号。无法以编程方式捕获 SIGKILL。通常杀死一个进程需要在命令行上输入这个，记住你可以对你登录到 shell 后拥有的进程执行这里操作：
ps -elf | grep myprocessThen to kill 'myprocess' by using the numeric process id based on the PID column from the previous output sample
kill -1 9149Depending on 'myprocess' and how the OS handles this, you will receive similar output as shown:
myprocess: received SIGKILL. process terminatedDepending on what happened, it is likely when your profiler ran the code, it somehow killed your application whether by intentionally or unintentionally, judging by your question:
My app broke on a line calling drawInRect on a UIImage instance top of call stack is CGGStateCreateCopy
It is likely that drawInRectwas supplied with a parameter that was invalid...you need to check the parameters used for that function and verify it. That could be the very reason why the OS killed your application...
很可能drawInRect提供了一个无效的参数......您需要检查用于该函数的参数并验证它。这可能就是操作系统杀死您的应用程序的真正原因......
Hope this helps, Best regards, Tom.
希望这会有所帮助，最好的问候，汤姆。
