Answer 1

When making URL from NSString, don't forget to encode it first, so try this:

NSString *urlString = [NSString stringWithFormat:@"%@", item.image];
NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];  

For IOS ≥ 9.0 use

NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]]];

Answer 2

In Swift:

NSURL(fileURLWithPath: item.image!)

Answer 3

item.image does not only contain the URL, but it starts with a newline and spaces. Remove those first and you should be fine.

Answer 4

All is ok, if you want to get the URL to print in NSLog use this:

NSLog(@"url> %@ ", [url absoluteString]);
