How to use iPhone Custom URL schemes

问题

I've got an app that I want to be able to use Custom URL schemes for. I want users to be able to open Tweetie using the Custom URL protocol however I need to populate the tweet with dynamic website link which I get using currentItem.link.

I found this code which launches Tweetie and populates a message with static information:

NSString *shortened_url = @"http://your.url.com";
NSString *stringURL = [NSString stringWithFormat:@"tweetie://%@", shortened_url];
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];

So using the above code how would I populate the message with currentItem.link information?

Thanks.

回答1:

It depends entirely on the application on the receiving end. You have to find out how their protocol works, then you can use their protocol as it is designed.

Adding a http:// protocol URL to the end of a tweetie:// protocol URL is not the correct method, and searching for how the Tweetie URL protocol works would be suggested.

The Tweetie protocol is documented, but it's not clear how much of this still applies since the client was converted to the official Twitter one. I believe that the format you want is:

NSString *stringURL = [NSString stringWithFormat:@"tweetie://post?message=%@", shortened_url];

I have already tried this to get the account selection parameter to work. The basic method works, but account selection does not for me.
