NSURl urlWithString replaces body with dots

Question

I try to convert NSString to NSURL however I receive truncated url.

NSURL *url = [NSURL fileURLWithPath:music.url];

If I make NSLog music.url I get:

/Users/Nikita/Library/Developer/CoreSimulator/Devices/D93FE148-7F72-43BB-A545-06D76C71300B/data/Containers/Data/Application/48BC6629-F054-4679-AC7B-709815EC5E2A/Library/Caches/4219609-357670045.mp3

And when NSLog received url:

/Users/Nikita/Library/Developer/CoreSimulator/Devices/D93FE148-7F72-43BB-A545-06D76C71300B/data/Containers/Data/Applicat ... 0045.mp3

The link is partially truncated.

What is the reason? Thank you

Answer 1

music.ulr is obviously an instance of NSString . url is an instance of NSURL . Using NSLog() an instance of a class makes its own decision how to be logged.

Objective-C object, printed as the string returned by descriptionWithLocale: if available, or description otherwise. Also works with CFTypeRef objects, returning the result of the CFCopyDescription function.

NSLog() prints only a description, not the complete object, whatever this should be.

Obviously the developer of NSString thought, that it is a good idea to print out the complete string and wrote a description method doing that. The developer of NSURL thought that it is enough to print the string partially, so you can recognize it.
