SIGABRT 坠毁......CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__
原标题:SIGABRT crash on __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE0_PERFORM_FUNCTION__

我有一个SIGABRT坠毁记录,对我不熟悉。 看一看它 exception倒了一种例外情况,但我看看一看该例外是在哪里列出的,或它的根源。

这在一家客户(iPad 2 /OS 4.3)上运行。

我会从哪里开始寻求诊断?

最佳回答

该方案应印刷有关该装置的独有性的信息(在装置连接时可在X条码组织器查阅)。 看到这一信息非常有益。

<代码>_NSThreadPerformPerform >在方法的家属中使用。 因此,看你如何使用这些方法。 具体来说,如果你可以再次要求某个物体做一个选择,而该选择并不支持。 这将造成一个例外。
