How to display Xcode output into terminal.app

Question

I'm having issues with getting xcode project output to display into my terminal.app. I can get the terminal to pop up on run, but how do I get the "output" to display into the terminal.app.

All NSLog are printed automatically in System log in Terminal.app.

If you want to see the results directly in your Terminal, you need to run the built product as a child of the Terminal, which means using something like /path/debug/build/MyProgram.app/Contents/MacOS/MyProgram to launch the app.

From Here.

EDIT:

If you want to redirect the NSLog to a file use :

-(void) redirectNSLogToFile {
     NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
     NSString *filePath=[paths objectAtIndex:0];
     NSString *logPath=[filePath stringByAppendingPathComponent:@"LogFile.txt"];
     freopen([logpath cStringUsingEncoding:NSASCIIStringEncoding],"a+",stderr);
}

So, I don't have to use the output files in xcdoe? – TWcode Mar 06 '13 at 17:26
What I really want is to get the apps output and export it into a text file. Is that possible or am I over thinking things? – TWcode Mar 06 '13 at 17:34
If you look at the pic you can see the output that I'm getting from my app in the "all output" screen. Is there a way to display that into a text file and/or terminal? – TWcode Mar 06 '13 at 17:36
I like this, but I made the file LogFile.txt and nothing happened. Where would I stick this method? – TWcode Mar 06 '13 at 18:30
whereever you write nslog, replace this with that – Anoop Vaidya Mar 06 '13 at 19:12

When you run your app in Xcode all the output is in the 'All Output' pane. If you want to preserve that just: select it, copy it, and paste it into a file (created with TextEdit or whatever).

By default, running your app in the Terminal.app won't preserve the output. You can use Unix pipes/redirects to get it into a file with, for example:

  $ /path/to/myapp > /path/to/LogFile.txt

Where would I put this redirect? – TWcode Mar 06 '13 at 18:06
The above is what you would type in the Terminal.app, to the shell (which is what actually runs in the Terminal.app). – GoZoner Mar 06 '13 at 18:49
Getting this error message /path/to/LogFile.txt: No such file or directory – TWcode Mar 06 '13 at 18:54
The notation '/path/to' means that you need to provide that information. The error message is saying that '/path/to' doesn't exist; which is true. If you want 'LogFile.txt' to be in your 'Home' folder use "~/LogFile.txt"; if you want it on your Desktop use "~/Desktop/LogFile.txt" – GoZoner Mar 06 '13 at 19:04
