Thanks Guys,
Yes I was not planning to use -[NSURL isEqual:]. Interestingly, Graham¹s
suggestion was to use NSSet, I was thinking what if I want to keep this

As a general principle, if you have to check whether one of a list of things is
part of another list of things, an array is the wrong container for the job,
because it amounts to a worst-case O(n^2) search. Instead, use a set or hash
table for the set of things that must be d

Hi All,
I have a question about efficiency when trying to compare NSURL. The
requirement is quite simple. I try and iterate through a directory to all
subdirectories and files. While doing this walk-through, I need to check
against an array of NSURLs which are restricted files and folders.

I just added iCloud and App Sandboxing entitlements to my app. I had to fix
some code that autosaves a file on launch to Application Support/, so now it
saves inside the Container.
But now I see the very brief flash of what I think is an Open file Panel, set
to some iCloud setting.

Using setEnvironment made it easily. I was looking for a complicated solution
when the solution was not so difficult.

Bryan,
I am trying to adapt your code to pdflatex. I hope it will work!!!
It seems that putting the option -l at the end was very important.
Do you know why? I have to admit that I put these « -c » and « -l » options
thanks to other answers, but I don’t know what they are doing.
Thanks very muc

Colas,
If my previous code snippet doesn’t work with pdflatex, NSTask has a
-setEnvironment method; it may allow you to set your task’s environment
variables.

Colas,
Bash’s -c option expects commands in a string which follows. Therefore, this
will work: I’m using /usr/bin/touch as an example, rather than your example of
pico, which is an interactive text editor.
NSTask * myTask = [[NSTask alloc]init];
NSArray * arguments = @[@"-c", @"/us

Terminal doesn't just run the shell (which, in turn, runs pico). It provides a
window and a TTY (terminal device) for the processes to use and translates the
I/O to the window. T

OK.
But without the simple quotes, it also fails.
With the quotes, the error is
/bin/bash: pico /Users/colas/myfile.txt: No such file or directory
Without the quotes, the error is
Error opening terminal: unknown.
Thanks!

From documentation
Colas,
Do you want your app to open a Terminal window, in which Pico has opened the
file at /Users/colas/myfile.txt?
If that’s so, I don’t think launching it via NSTask is going to get you
anything.
What is the end result you want to achieve?

I don’t know what they mean by “special”, but anyhow, the ‘ ' you put around
