How to clear console programmatically in Xcode?
提问by NSExplorer
I have a bunch of NSLog statements in my code which I use for debugging. Every time I run my Project I'd like to start from a fresh console screen. Is there any command I can embed in my code which can do this?
我的代码中有一堆 NSLog 语句用于调试。每次我运行我的项目时，我都想从一个新的控制台屏幕开始。是否有任何命令可以嵌入我的代码中可以做到这一点？

Maybe you could use the "Auto Clear Debug Console" setting in the XCode Preferences.. Don't know if this answers your question?
也许您可以使用 XCode 首选项中的“自动清除调试控制台”设置.. 不知道这是否能回答您的问题？

I think the only thing you can is
我认为你唯一能做的就是
for(int i= 0; i < 100; i++)
NSLog(@" ");
just like in good old MS-DOS :)
就像在旧的 MS-DOS 中一样 :)

If you are talking about the console in the Xcode window there is a "Clear Console" option in the "Run" menu. There is also, in the "Debugging" Preferences tab an "Auto Clear Debug Console" checkbox. I am referring Xcode 3.2.x
如果您在 Xcode 窗口中谈论控制台，则“运行”菜单中有一个“清除控制台”选项。在“调试”首选项选项卡中还有一个“自动清除调试控制台”复选框。我指的是 Xcode 3.2.x

The debugger console / run log are basically a redirected "log this to the console" command from your app. "Clearing" it means nothing in the general sense, since the messages are usually just shunted somewhere (like a file). Your application would have to know about its debugging environment and be able to tell that environment to clear whatever it's logging to.
调试器控制台/运行日志基本上是来自您的应用程序的重定向“将其记录到控制台”命令。“清除”在一般意义上没有任何意义，因为消息通常只是被分流到某个地方（如文件）。您的应用程序必须了解它的调试环境，并能够告诉该环境清除它正在记录的任何内容。
In short: I suppose it's not impossiblebut it's ridiculously inconvenient.
简而言之：我认为这并非不可能，但它非常不方便。

As mentioned by stackr, the "Auto Clear Debug Console" setting in the XCode Preferences will do this. To do it in code:
正如 stackr 所提到的，XCode 首选项中的“自动清除调试控制台”设置将执行此操作。要在代码中做到这一点：
bool ClearXCodeDebuggerConsole()
{
NSString *const scriptText = @"\
tell application \"System Events\"\n\
set currentapp to the name of the current application\n\
end tell\n\
tell application \"Xcode\" to activate\n\
tell application \"System Events\"\n\
keystroke \"r\" using {command down, control down, option down}\n\
end tell\n\
tell application currentapp to activate\n\
return true";
NSAppleScript *script = [[[NSAppleScript alloc] initWithSource:scriptText] autorelease];
[scriptText release];
NSDictionary *dictError = nil;
NSAppleEventDescriptor *result = [script executeAndReturnError:&dictError];
if (!result) return false;
if ([result booleanValue] != YES) return false;
return true;
}
