I tried BOOL ImageMagick = [[NSFileManager defaultManager]
fileExistsAtPath:@"/ImageMagick*/" isDirectory:YES];
You're calling that wrong, the second parameter expects a pointer to a
BOOL, not an actual BOOL. The correct syntax is:
BOOL directory;
BOOL exists = [[NSFileManager defaultManager] fileExistsAtPath:@"/
ImageMagick/" isDirectory:&directory];
But anyway, you're probably best getting the directory contents of
where ImageMagick should be installed and running through it. I'm not
familiar with ImageMagick; I don't even know what it is! But you
should bear in mind that if it's relocatable you'll want to check all
the possible locations.
Take a look at NSSearchPathForDirectoriesInDomains() in the docs.
