Hell all,
Let's suppose I've got NSString @"C:omponent" , which represents
the name of a file. Is there a way to instruct NSString class not
to treat a leading single letter followed by a column as a path
separator? Namely, I need this one treated as only one path
component @"C:omponent", but NSString sees two, @"C:" and
"omponent". So, if I ask for the last path component, I get
@"omponent" instead of the whole string @"C:omponent".
I've searched documentation, took a look into NSPathUtilities.h,
but no help.
You can use the CFURL API which provide a set of function to
manipulate path, but due to memory management, it's not as clean
than the Cocoa string API (objects are not autoreleased).
• CFURLCreateCopyAppendingPathComponent
• CFURLCreateCopyAppendingPathExtension
• CFURLCreateCopyDeletingLastPathComponent
• CFURLCreateCopyDeletingPathExtension
CFURLCopyPathExtension
CFURLCopyLastPathComponent
etc…
Or to stay entirely in Cocoa-land, you could always use
NSArray* components = [filePath componentsSeparatedByString:@"/"];
NSString* lastPathComponent = [components objectAtIndex:([components
count] - 1)];
Not quite as straightforward as the methods in NSPathUtilities but it
would certainly work around the colon issue...
