Answer 1

I think it's good solution:

NSURL *bUrl = [aUrl URLByAppendingPathComponent:@"newString"];

In Swift you could do the following,

var bURL = aURL.URLByAppendingPathComponent( "newString" )

You can also state whether the URL is a directory,

var bURL = aURL.URLByAppendingPathComponent( "newString", isDirectory: true )

Answer 2

I think it's as simple as:

    NSString *s = [aUrl.path stringByAppendingString:@"newString"];

Answer 3

If you have a file NSURL to a directory and you want to end up with a NSString containing the NSURL's path with a file name appended to it, use this:

NSURL *url = [NSURL fileURLWithPath:@"/System" isDirectory:YES];
NSString *filename = @"foo";
NSString *result = [url.path stringByAppendingPathComponent:filename];

You can also use URLByAppendingPathComponent but that adds an extra step which creates an extra NSURL object that isn't needed.

NSURL *url = [NSURL fileURLWithPath:@"/System" isDirectory:YES];
NSString *filename = @"foo";
NSURL *newURL = [url URLByAppendingPathComponent:filename];
NSString *result = newURL.path;
