How to resolve ftp url with special characters like @,$?

Question

有人可以建议如何使用特殊字符解析ftp网址。

Answer 1

Take the string, use the stringByAddingPercentEscapesUsingEncoding method to escape it, then you can use it normally:

NSString *fuzzyUrl = @"ftp://jailbreak.apple.com/?foo=@@@&bar=$$$&baz=¥¥¥";
NSString *urlString = [fuzzyUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [[NSURL alloc] initWithString:urlString];
// ...
// your code here
// ...
[url release];
