Getting substring from NSString

Question

I have a NSString which looks like this:

http://fiskltd.com/components/com_jshopping/files/img_products/thumb_09afd9f041af34fb0cffec1e0b1222e8.jpg

And I need extract from that this string:

thumb_09afd9f041af34fb0cffec1e0b1222e8.jpg

I will have lots of such strings, so I won't know the number of characters and how many of them will the name of the picture. Can anyone tell me how to extract the name of picture?

Answer 1

Try this:

NSString *originalString = @"http://fiskltd.com/components/com_jshopping/files/img_products/thumb_09afd9f041af34fb0cffec1e0b1222e8.jpg";
NSString *filename = [originalString lastPathComponent];

Apple docs here.

Answer 2

可能是你的情况下最好的解决方案是[NSString lastPathComponent] 。
