Question

NSURL *url = [NSURL URLWithString:@"appName://<?xml version=\"1.0\" encoding=\"UTF-8\"?>"];

But the url = nil. I found if I remove the “<” and “>” signs, it will be ok.
So, the two signs cannot be used in a URL? Should I replace the signs with another one?

Thanks!

I solved this problem.
Before I do NSURL *url = [NSURL URLWithString:@”….”];
I first do:

    NSString *urlStr = [string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

And when parse this url on the receiver side, I firstly do:

NSString *urlString = [[url absoluteString] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; // url is a NSURL
