po command in Xcode does not generate output
提问by cheesus
At some point during my work, Xcode's poand pcommands stopped working. No matter what I enter, it doesn't generate output:
在我工作的某个时候，Xcodepo和p命令停止工作。无论我输入什么，它都不会生成输出：
(gdb) po self
(gdb) po [self name]
(gdb) po [UITableView class]
(gdb) po @"Hello"
(gdb) p indexPath.row
(gdb) print indexPath.row
(gdb) po fjkldsjflksdjklwjfkljfkldsjflk
(gdb)
When I enter any of these commands, the command line just goes to the next line, where it prints the blue (gdb), but no output.
当我输入这些命令中的任何一个时，命令行只会转到下一行，在那里打印 blue (gdb)，但没有输出。
I tried the following steps:
我尝试了以下步骤：
- Restart Xcode, restart my Macbook
- Tried while debugging in the simulator as well as on a iOS device
- Switched to LLDB and restarted
- Re-installed Xcode
- 重启 Xcode，重启我的 Macbook
- 在模拟器和 iOS 设备上调试时试过
- 切换到LLDB并重新启动
- 重新安装Xcode
The other debugging tools in Xcode seem to work okay: Breakpoints, step-by-step execution, the Autovariable examination window etc.
Xcode 中的其他调试工具似乎工作正常：断点、逐步执行、自动变量检查窗口等。
Any ideas?
有任何想法吗？
EDIT:Doesn't work even after a re-install of Xcode.
编辑：即使在重新安装 Xcode 后也不起作用。

Silly me, I was in the 'Target Output' window instead of the 'Debugger Output' window.
愚蠢的我，我在“目标输出”窗口而不是“调试器输出”窗口中。
Somehow I thought I checked the other console windows there, but apparently I didn't.
不知何故，我以为我检查了那里的其他控制台窗口，但显然我没有。

I added filter in debugger which hid other logs. Removing the filter worked for me.
我在调试器中添加了过滤器，它隐藏了其他日志。移除过滤器对我有用。
