If I have a file name like this how do I get the path extension?
http://example.com/image.png?key=value
If I use -pathExtension
for NSString
it returns jpg?key=value
.
I want to get the true extension from the path so just jpg
.
Try your code in swift. It works fine.
let url = URL(string: "http://example.com/image.png?key=value")
print(url?.pathExtension) //Optional("png")
Try this:
NSURL *url = [NSURL URLWithString:@"http://example.com/image.png?key=value"];
NSString *ext = [[url lastPathComponent] pathExtension];
NSLog(@"%@", ext) ; // png
