所有的exception断点在模拟器上无故停止
这是非常烦人的，每次我试图在“所有exception断点”在模拟器上debugging，应用程序停在这一行没有理由：
return UIApplicationMain(argc, argv, nil, NSStringFromClass([STAppDelegate class])); 有没有人发现他自己在这个问题上挣扎？
谢谢！

我只是遇到同样的问题，并追踪到这个问题。
确保您在Info.plist指定Fonts provided by this application下的所有字体实际上都在您的应用程序包中。
回溯显示，该应用程序没有任何理由停止。 它停止了，因为引发了一个exception，它看起来像一个C ++exception。
与Objective-C不同的是，由于编程错误只能引发exception，因此非常罕见，因此会引发大量的C ++代码，并捕获大量exception。 在这种情况下，最好只设置一个Objective-Cexception的断点，而不是所有的exception。
抛出一个exception，但是调用者（例如在libFontParser和libTrueTypeScaler中）正在处理它，它并没有到达你的程序。
除非您看到其他问题的证据（例如日志消息），或者exception到达您的程序，否则假定实施正在处理它。 您可以继续在debugging器中通过这些实例，而不用担心。
