Question

我只是想开始优化我的应用并通过Instruments启动它。但无论我使用哪种工具，我的应用程序在启动时都会立即崩溃。

当我正常运行我的应用时，它不显示任何问题。此外，我在几天/几周前用仪器运行它没有问题。但今天它甚至都没有开始。

仪器显示以下内容（从短期开始）

Total Samples   Running Time    Self        Symbol Name
322 322.0ms   92.0% 0,0     Main Thread  0x1734
256 256.0ms   73.1% 0,0      start

9   9.0ms    2.5%   0,0     _dispatch_mgr_thread  0x1752
7   7.0ms    2.0%   0,0     _dispatch_worker_thread3  0x1756
5   5.0ms    1.4%   0,0     _dispatch_worker_thread3  0x1755
4   4.0ms    1.1%   0,0     start_wqthread  0x1754
2   2.0ms    0.5%   0,0     _dispatch_worker_thread3  0x1753

在这里，我想展示应用程序崩溃的一部分（尽管可能没用），但它甚至无法启动我的应用程序。 Aaaarrrggghhhhh

等等 - 控制台日志！
