how to send push from iphone via urban airship?

Question

I have an urban airship account and my iOS app ist already configured with the system. My device token is on the server and if I send a test notification from the server I get the notification on my iphone. BUT how can I send a message FROM my iphone to another user? I haven't found any stuff about sending through iphone. This is my code:

NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://go.urbanairship.com/api/push/"]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSDictionary *push;
push = @{@"aps":@{@"alert":@"How are you?"},@"device_tokens":@[@"87892382J393FS77789S90909N82022312332"]};

and then I have to send it as json or something else???

Answer 1

As documentation on http://docs.urbanairship.com/reference/api/v3/intro.html says, requests are http ones with JSON body.

You need to authorize first. From documentation:

The username portion is the application key. The password portion is either the application secret, or master secret.

You can find in this question how to authorize on iOS:

NSString *authStr = [NSString stringWithFormat:@"%@:%@", [self username], [self password]];
NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding];
NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodingWithLineLength:80]];
[request setValue:authValue forHTTPHeaderField:@"Authorization"];

And then I guess you should do like this:

#import "JSONKit.h"

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://go.urbanairship.com/api/push/"]];
request.HTTPMethod = @"POST";
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

NSDictionary *push = @{@"aps":@{@"alert":@"How are you?"},@"device_tokens":@[@"87892382J393FS77789S90909N82022312332"]};
request.HTTPBody = [push.JSONString dataUsingEncoding:NSUTF8StringEncoding];
[NSURLConnection sendSynchronousRequest:req returningResponse:nil error:nil];

Note that you need JSONKit to serialize your dictionary into string

Answer 2

OK this is my actually Method:

- (IBAction)sendPush:(id)sender {
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://go.urbanairship.com/api/push/"]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

NSString *authStr = [NSString stringWithFormat:@"app key:app secret"];
NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding];
NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodedDataWithOptions:nil]];
[request setValue:authValue forHTTPHeaderField:@"Authorization"];

NSDictionary *push = @{@"aps":@{@"alert":@"How are you?"},@"device_tokens":@[@"87892382J393FS77789S90909N82022312332"]};
request.HTTPBody = [push.JSONString dataUsingEncoding:NSUTF8StringEncoding];
NSLog(@"push: %@",push);
NSLog(@"request: %@",request);
[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
}

If I comment the line 6-10 out then I get for the NSLog:

2013-11-06 12:59:13.238 myApp[7273:907] push: {
aps =     {
    alert = "How are you?";
};
"device_tokens" =     (
    87892382J393FS77789S90909N82022312332
);
}
2013-11-06 12:59:13.241 myApp[7273:907] request: <NSMutableURLRequest https://go.urbanairship.com/api/push/>

I really don't know why it doesn't works!!!

Just FYI, doing this would present a risk in a publicly released app.

Any push through UA requires your master secret to authenticate. If you added your master secret to the app, it would be viewable to a savvy hacker, who could then use it to send unauthorized pushes on your behalf. It has happened to people before.

It's not generally recommended.

This is an Example using the API V3

-(void)richPushNotification{

NSDictionary *push = @{

                       @"audience" : @{
                               @"device_token" : deviceToken
                               },
                       @"device_types" : @[ @"ios" ],
                       @"notification" : @{
                               @"ios" : @{
                                       @"alert":Message,
                                       @"sound":@"default",
                                       @"badge":@"auto",
                                       }
                               },
                       @"message": @{
                               @"title": Message,
                               @"body": @"<html><body><h1>blah blah</h1> etc...</html>",
                               @"content_type": @"text/html",
                               @"extra": @{
                                       @"offer_id" : @"608f1f6c-8860-c617-a803-b187b491568e"
                                       }
                               }
                       };


NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://go.urbanairship.com/api/push/"]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/vnd.urbanairship+json; version=3;" forHTTPHeaderField:@"Accept"];

NSString *authStr = [NSString stringWithFormat:@"%@:%@", appKey, appMasterSecret];
NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding];
NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed]];
[request setValue:authValue forHTTPHeaderField:@"Authorization"];


NSData *jsonData = [NSJSONSerialization dataWithJSONObject:push
                                                   options:0 // Pass 0 if you don't care about the readability of the generated string
                                                     error:NULL];

request.HTTPBody = jsonData;

[NSURLConnection connectionWithRequest:request delegate:self];

}

And The Response:

- (void) connection:(NSURLConnection *) connection didReceiveResponse:(NSURLResponse *) response {
NSHTTPURLResponse * res = (NSHTTPURLResponse *) response;
NSLog(@"response: %@",res);
NSLog(@"res %li\n",(long)res.statusCode);

if (res.statusCode == 202) {

    //Show Alert Message Sent

}else{

    //Handle Error

}

}
