iphone - Debug模式和断点的 Xcode 问题

Question

我有这样的情况:当我使用断点运行我的项目时，编译器会转到第一个断点并像往常一样停止程序，直到我按下下一步按钮。但是当我下一步 - 他那边没有反应，然后我点击 2-3 次“下一步”(进入)按钮 - 之后他运行程序到最后并且没有反应。

我尝试这样做:Build->Clear All Targets - 但它没有给出任何结果。尝试重新启动计算机 - 同样的效果。

调试器日志如下:

The Debugger has exited due to signal 15 (SIGTERM).The Debugger has exited due to signal 15 (SIGTERM).

经过进一步审查，原因似乎是这段代码:

NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [path objectAtIndex: 0];
    NSString *fname = [documentsDirectory stringByAppendingPathComponent: @"phoneBook.sqlite3"];

此代码获取可执行文件的当前目录，然后我在那里创建我的数据库文件。第一次都很好，第二次 - 不好。这可能是什么原因造成的，我该如何解决？

Answer 1

执行 Cmd + Opt + B 以显示所有断点。删除所有断点。现在通过 iPhone Simulator -> Reset Content and Settings 清除您的模拟器，然后再试一次。
