Q:

get access to a file of another PC through NSURL

I can access to my local file through NSURL by using:
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"file://localhost/Users/user/Desktop/lucky_numbers.json"]];  

But I need to get access of a file of another PC. 
I tried:    
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"file://foyzulkarim:000000@192.168.1.48/localhost/Users/foyzulkarim/Desktop/lucky_numbers.json"]];

and
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"file://192.168.1.48/localhost/Users/foyzulkarim/Desktop/lucky_numbers.json"]];

and
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"file://Foyzul-Karims-MacBook.local/localhost/Users/foyzulkarim/Desktop/lucky_numbers.json"]];
But Error shows NSURLError domain code -1100
Please help me if anyone knows how to do this. 

A:

You can access to my local file through NSURL by using:  NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"file://192.168.1.48/localhost/Volumes/foyzulkarim/Desktop/lucky_numbers.json"]];
but, to do this you have to first connect with that PC manually.
