HTTP Post help - iOS app

I've successfully implemented push notifications with Urban Airship in my app, but I want to make an administrative password-protected part of the app that enables one to send the push notifications from any authorized iPhone with the app installed. I need a way so whatever i typ开发者_如何学Ce in a text box is send via https POST to https://go.urbanairship.com/api/push/broadcast. Can anyone recommend or tell me a way to do this?

You can use NSURLConnection to do this. Setup an NSMutableURLRequest with the post data and other information, and then use NSURLConnection to post it and get a response:

NSString * postString = [NSString stringWithFormat:@"field1=%@", myItem];
NSData * postData = [postString dataUsingEncoding:NSUTF8StringEncoding];
NSURL * myURL = [NSURL URLWithString:@"https://go.urbanairship.com/api/push/broadcast"];
NSMutableURLRequest * request = [[NSMutableURLRequest alloc] initWithURL:myURL
                                                             cachePolicy:NSURLRequestReloadIgnoringCacheData
                                                         timeoutInterval:10];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%d", [postData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postData];

NSData * returnedData = [NSURLConnection sendSynchronousRequest:request
                                              returningResponse:nil error:nil];

You can also use NSURLConnection for asynchronous requests. See the NSURLConnection Class Reference.
