如何在NSString中多次出现的特定字符之后获取NSString？

Question

I have a complete URL, say

http://www.mywebsite.com//Folder /Detals /Final Image /La Image Logo.jpg

Here in this NSString, I only want to fetch

La Image Logo.jpg

How can I do so?

Thanks

Answer 1

[string lastPathComponent]应该可以解决问题

Answer 2

If it's about the filename in a URL you should definitely create an NSURL object and query that object for the desired information:

NSURL *url = [NSURL URLWithString:@"http://www.mywebsite.com//Folder /Detals /Final Image /La Image Logo.jpg"];
NSString *filename = [url lastPathComponent];

NSURL is good at parsing URL strings. This way you're sure that you don't get any fragment part ("#anchor") or parameters ("?q=foo&p=bar") in your filename.

Answer 3

您可以使用NSString *string=[[yourString componentsSeparatedByString:@"/"] lastObject]
