Convert an NSURL to an NSString

问题

I have an app where the user can choose an image either from the built-in app images or from the iphone photo library. I use an object Occasion that has an NSString property to save the imagePath.

Now in the case of the built-in app images I do get the file name as an NSString an save in the [occasion imagePath]. But in the 2nd case where the user picks an image form the photo library I get an NSURL which I want to convert to an NSString to be able to save it in [occasion imagePath].

Is it possible to convert the NSURL to an NSString?

回答1:

In Objective-C:

NSString *myString = myURL.absoluteString;

In Swift:

var myString = myURL.absoluteString

More info in the docs:

回答2:

If you're interested in the pure string:

[myUrl absoluteString];

If you're interested in the path represented by the URL (and to be used with NSFileManager methods for example):

[myUrl path];

回答3:

Try this in Swift :

var urlString = myUrl.absoluteString

Objective-C:

NSString *urlString = [myURL absoluteString];

回答4:

Swift update:

var myUrlStr : String = myUrl.absoluteString

回答5:

I just fought with this very thing and this update didn't work.

This eventually did in Swift:

let myUrlStr : String = myUrl!.relativePath!

回答6:

You can use any one way

NSString *string=[NSString stringWithFormat:@"%@",url1];

or

NSString *str=[url1 absoluteString];

NSLog(@"string :: %@",string);

string :: file:///var/containers/Bundle/Application/E2D7570B-D5A6-45A0-8EAAA1F7476071FE/RemoDuplicateMedia.app/loading_circle_animation.gif

NSLog(@"str :: %@", str);

str :: file:///var/containers/Bundle/Application/E2D7570B-D5A6-45A0-8EAA-A1F7476071FE/RemoDuplicateMedia.app/loading_circle_animation.gif

In Swift :- var str_url = yourUrl.absoluteString

It will result a url in string.
