Admob App Conversion tracking setup

Target Platforms Mobile

Hi,

I’m trying to set up the app conversion tracking from Admob. I need to add the two codes snippets:

[self performSelectorInBackground:@selector(reportAppOpenToAdMob) withObject:nil];

// This method requires adding #import <CommonCrypto/CommonDigest.h> to your source file.
- (NSString *)hashedISU {
  NSString *result = nil;
  NSString *isu = [UIDevice currentDevice].uniqueIdentifier;
 
  if(isu) {
    unsigned char digest[16];
    NSData *data = [isu dataUsingEncoding:NSASCIIStringEncoding];
    CC_MD5([data bytes], [data length], digest);
 
    result = [NSString stringWithFormat: @"%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x",
           digest[0], digest[1], 
           digest[2], digest[3],
           digest[4], digest[5],
           digest[6], digest[7],
           digest[8], digest[9],
           digest[10], digest[11],
           digest[12], digest[13],
           digest[14], digest[15]];
    result = [result uppercaseString];
  }
  return result;
}

- (void)reportAppOpenToAdMob {
  NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // we're in a new thread here, so we need our own autorelease pool
  // Have we already reported an app open?
  NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                  NSUserDomainMask, YES) objectAtIndex:0];
  NSString *appOpenPath = [documentsDirectory stringByAppendingPathComponent:@"admob_app_open"];
  NSFileManager *fileManager = [NSFileManager defaultManager];
  if(![fileManager fileExistsAtPath:appOpenPath]) {
    // Not yet reported -- report now
    NSString *appOpenEndpoint = [NSString stringWithFormat:@"http://a.admob.com/f0?isu=%@&md5=1&app_id=%@",
                                 [self hashedISU], @"<APPLE ITUNES ID>"];
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:appOpenEndpoint]];
    NSURLResponse *response;
    NSError *error = nil;
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    if((!error)  ([(NSHTTPURLResponse *)response statusCode] == 200)  ([responseData length] > 0)) {
      [fileManager createFileAtPath:appOpenPath contents:nil attributes:nil]; // successful report, mark it as such
      NSLog(@"App download successfully reported.");
    } else {
      NSLog(@"WARNING: App download not successfully reported. %@", [NSString stringWithData:responseData encoding:NSUTF8StringEncoding]);
    }
  }
  [pool release];
}

Here is my problem, I know Unity well but with Xcode, I’ve got no clue what’s going on… I looked online to find where to place them and how to do it.
Atm, I placed them in iPhone_target2AppDelegate.m

like this:

//
//  iPhone_target2AppDelegate.m
//  iPhone-target2
//
//  Created by Renaldas on 8/22/08.

#import "iPhone_target2AppDelegate.h"

#import <CommonCrypto/CommonDigest.h>

@implementation iPhone_target2AppDelegate

@synthesize window;

- (void)applicationDidFinishLaunching:(UIApplication *)application {	
	
	// Override point for customization after app launch
    [self performSelectorInBackground:@selector(reportAppOpenToAdMob) withObject:nil];
    [window makeKeyAndVisible];
    
}


- (void)dealloc {
	[window release];
	[super dealloc];
}

// This method requires adding #import <CommonCrypto/CommonDigest.h> to your source file.
- (NSString *)hashedISU {
  NSString *result = nil;
  NSString *isu = [UIDevice currentDevice].uniqueIdentifier;
 
  if(isu) {
    unsigned char digest[16];
    NSData *data = [isu dataUsingEncoding:NSASCIIStringEncoding];
    CC_MD5([data bytes], [data length], digest);
 
    result = [NSString stringWithFormat: @"%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x",
           digest[0], digest[1], 
           digest[2], digest[3],
           digest[4], digest[5],
           digest[6], digest[7],
           digest[8], digest[9],
           digest[10], digest[11],
           digest[12], digest[13],
           digest[14], digest[15]];
    result = [result uppercaseString];
  }
  return result;
}

- (void)reportAppOpenToAdMob {
  NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // we're in a new thread here, so we need our own autorelease pool
  // Have we already reported an app open?
  NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                  NSUserDomainMask, YES) objectAtIndex:0];
  NSString *appOpenPath = [documentsDirectory stringByAppendingPathComponent:@"admob_app_open"];
  NSFileManager *fileManager = [NSFileManager defaultManager];
  if(![fileManager fileExistsAtPath:appOpenPath]) {
    // Not yet reported -- report now
    NSString *appOpenEndpoint = [NSString stringWithFormat:@"http://a.admob.com/f0?isu=%@&md5=1&app_id=%@",
                                 [self hashedISU], @"<APPLE ITUNES ID>"];
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:appOpenEndpoint]];
    NSURLResponse *response;
    NSError *error = nil;
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    if((!error)  ([(NSHTTPURLResponse *)response statusCode] == 200)  ([responseData length] > 0)) {
      [fileManager createFileAtPath:appOpenPath contents:nil attributes:nil]; // successful report, mark it as such
      NSLog(@"App download successfully reported.");
    } else {
      NSLog(@"WARNING: App download not successfully reported. %@", [NSString stringWithData:responseData encoding:NSUTF8StringEncoding]);
    }
  }
  [pool release];
}


@end

As you can see I’ve added the #import <CommonCrypto/CommonDigest.h> on the top…
When I launch the app, I’ve got no feedback. It s supposed to say:
“App download successfully reported.” or this “WARNING: App download not successfully reported.” But I don’t get anything at all.

Does anyone could help me out on how to set up this conversion tracking system ? It seems pretty easy but I don’t have the knowledge in Xcode to fully understand what I’m doing in it… :slight_smile:

Thanks for the help

P.S. I took off my apple itunes ID from the code posted but not on the code I use.

Hello
In the applicationDidFinishLaunching method
add the colons after the reportAppOpenToAdMob call .
