将NSURL转换为NSString。

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.

我有一个应用程序，用户可以从内置的应用程序图像或iphone照片库中选择一个图像。我使用具有NSString属性的对象场景来保存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].

现在，在内置的应用程序映像中，我确实将文件名作为NSString，保存在[场景imagePath]中。但是在第二种情况下，用户选择一个图像格式的照片库我得到一个NSURL，我想要转换成NSString，以便在[场景imagePath]中保存它。

Is it possible to convert the NSURL to an NSString?

是否可以将NSURL转换为NSString?

If you're interested in the pure string:

如果你对纯字符串感兴趣:

[myUrl absoluteString];

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

如果您对URL表示的路径感兴趣(并使用NSFileManager方法):

[myUrl path];

#3

Try this in Swift :

试试这个吧:

var urlString = myUrl.absoluteString

Objective-C:

objective - c:

NSString *urlString = [myURL absoluteString];

#4

Swift update:

迅速更新:

var myUrlStr : String = myUrl.absoluteString

#5

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

我只是和这个东西斗争，这个更新没用。

This eventually did in Swift:

这最终在斯威夫特:

let myUrlStr : String = myUrl!.relativePath!

You can use any one way

你可以用任何一种方法。

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

或

NSString *str=[url1 absoluteString];

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